JPA difference Windows / Unix System? - json

For development purposes i'm using a windows environment (Eclipse / Jboss)
There i have a userDAO, that offers the method to rerieve a UserEntity by first- and lastname. This Query runs well on the dev environment. However on the Unix-Environment, i get a javax.persistence.NoResultException: No entity found for query Exception.
Situation in Detail:
A REST-Service is beeing called, containing many Data, along with a firstname and lastname. this parameters needs to be used to obtain the actuall userEntity. (It fails for ANY user on Unix.)
So, the rest service is doing this:
#Consumes("application/json")
#Produces("application/json")
public String create(String plaindata) {
JSONObject data = new JSONObject(plaindata);
String ownerFirstname = data.getString("userFirstname"); //Yes userX, not ownerX
String ownerLastname = data.getString("userLastname");
UserEntity owner = null;
try {
owner = userDataService.getUserDetailsByName(ownerFirstname, ownerLastname);
} catch (Exception e) {
throw new Exception("Found zero possible users for the given name '" + ownerFirstname + " " + ownerLastname
+ "'. Cannot invoke process.", e);
}
...
}
The userDataService looks (stripped) like this:
private static String GET_USER_BY_FIRSTNAME_LASTNAME_QUERY = "SELECT * FROM " + DBConstants.USER_TABLE_NAME
+ " user WHERE user.FIRST_NAME = :firstnameValue AND user.LAST_NAME = :lastnameValue";
public UserEntity getUserDetailsByName(String firstname, String lastname) {
Query query = em.createNativeQuery(GET_USER_BY_FIRSTNAME_LASTNAME_QUERY, UserEntity.class);
query.setParameter("firstnameValue", firstname);
query.setParameter("lastnameValue", lastname);
UserEntity u = (UserEntity) query.getSingleResult();
return u;
}
DBConstants contains the table name like:
public static final String DATATABLE_PREFIX = "pre_";
public static final String USER_TABLE_NAME = DATATABLE_PREFIX+"user_entity";
Column Names in mySQL are Capitalized, so everything seems right.
this works on a Windows Environment, but NOT in the Unix Environment :(

String ownerFirstname = data.getString("userFirstname").trim();
String ownerLastname = data.getString("userLastname").trim();
And it works... Strange thing - what could be the difference between windows and unix towards this issue? (The Exception logged absolutely NO Whitespace)

Spring Boot SQL JPA not using correct replica

I have an application where I am trying to distribute reads & writes between two replicas. For some reason JPA is only using my read-replica, not the write replica. The write replica is the primary replica. The result is that when I use JPA to try and write data I get and 'UPDATE command denied' error because it is using the read only datasource. I have tried doing my own annotation and using the #Transactional annotation. Both annotations are called via AOP with the correct datasource but JPA will not use it.
FYI Spring JDBC works correctly via the custom annotation. This is strictly a JPA issue. Below is some code:
My AOP class:
#Aspect
#Order(20)
#Component
public class RouteDataSourceInterceptor {
#Around("#annotation(com.kenect.db.common.annotations.UseDataSource) && execution(* *(..))")
public Object proceed(ProceedingJoinPoint pjp) throws Throwable {
try {
MethodSignature signature = (MethodSignature) pjp.getSignature();
Method method = signature.getMethod();
UseDataSource annotation = method.getAnnotation(UseDataSource.class);
RoutingDataSource.setDataSourceName(annotation.value());
return pjp.proceed();
} finally {
RoutingDataSource.resetDataSource();
}
}
#Around("#annotation(transactional)")
public Object proceed(ProceedingJoinPoint proceedingJoinPoint, Transactional transactional) throws Throwable {
try {
if (transactional.readOnly()) {
RoutingDataSource.setDataSourceName(SQL_READ_REPLICA);
Klogger.info("Routing database call to the read replica");
} else {
RoutingDataSource.setDataSourceName(SQL_MASTER_REPLICA);
Klogger.info("Routing database call to the primary replica");
}
return proceedingJoinPoint.proceed();
} finally {
RoutingDataSource.resetDataSource();
}
}
}
My RoutingDataSource class:
public class RoutingDataSource extends AbstractRoutingDataSource {
private static final ThreadLocal<String> currentDataSourceName = new ThreadLocal<>();
public static synchronized void setDataSourceName(String name) {
currentDataSourceName.set(name);
}
public static synchronized void resetDataSource() {
currentDataSourceName.remove();
}
#Override
protected Object determineCurrentLookupKey() {
return currentDataSourceName.get();
}
}
AbstractDynamicDataSourceConfig
public abstract class AbstractDynamicDataSourceConfig {
private final ConfigurableEnvironment environment;
public AbstractDynamicDataSourceConfig(ConfigurableEnvironment environment) {
this.environment = environment;
}
protected DataSource getRoutingDataSource() {
Map<String, String> props = DBConfigurationUtils.getAllPropertiesStartingWith("spring.datasource", environment);
List<String> dataSourceNames = DBConfigurationUtils.getDataSourceNames(props.keySet());
RoutingDataSource routingDataSource = new RoutingDataSource();
Map<Object, Object> dataSources = new HashMap<>();
DataSource masterDataSource = null;
for (String name : dataSourceNames) {
DataSource dataSource = getDataSource("spring.datasource." + name);
dataSources.put(name, dataSource);
if (masterDataSource == null && name.toLowerCase().contains("master")) {
masterDataSource = dataSource;
}
}
if (dataSources.isEmpty()) {
throw new KenectInvalidParameterException("No datasources found.");
}
routingDataSource.setTargetDataSources(dataSources);
if (masterDataSource == null) {
masterDataSource = (DataSource) dataSources.get(dataSourceNames.get(0));
}
routingDataSource.setDefaultTargetDataSource(masterDataSource);
return routingDataSource;
}
protected DataSource getDataSource(String prefix) {
HikariConfig hikariConfig = new HikariConfig();
hikariConfig.setJdbcUrl(environment.getProperty(prefix + ".jdbcUrl"));
hikariConfig.setUsername(environment.getProperty(prefix + ".username"));
hikariConfig.setPassword(environment.getProperty(prefix + ".password"));
return new HikariDataSource(hikariConfig);
}
}
application.yaml
spring:
datasource:
master:
jdbcUrl: jdbc:mysql://my-main-replica
username: some-user
password: some-password
read-replica:
jdbcUrl: jdbc:mysql://my-read-replica
username: another-user
password: another-password
If I use the annotation on with JDBC template then it works as expected:
THIS WORKS:
// Uses main replica as it is not specified
public Message insertMessage(Message message) {
String sql = "INSERT INTO message(" +
" `conversationId`," +
" `body`)" +
" VALUE (" +
" :conversationId," +
" :body" +
")";
MapSqlParameterSource parameters = new MapSqlParameterSource();
parameters.addValue("conversationId", message.getConversationId());
parameters.addValue("body", message.getBody());
namedJdbcTemplate.update(sql, parameters);
}
// Uses read replica
#UseDataSource(SQL_READ_REPLICA)
public List<Message> getMessage(long id) {
MapSqlParameterSource parameters = new MapSqlParameterSource();
parameters.addValue("id", id);
String sql = "SELECT " +
" conversationId," +
" body" +
" FROM message"
" WHERE id = :id";
return namedJdbcTemplate.query(sql, parameters, new BeanPropertyRowMapper<>(Message.class));
}
If I use a JPA interface it always uses the read replica:
THIS FAILS:
#Repository
public interface MessageJpaRepository extends JpaRepository<MessageEntity, Long> {
// Should use the main-replica but always uses the read-replica
#Modifying
#Query(value =
"UPDATE clarioMessage SET" +
" body = :body" +
" WHERE id = :id" +
" AND organizationId = :organizationId",
nativeQuery = true)
#Transactional
int updateMessageBodyByIdAndOrganizationId(#Param("body") String body, #Param("id")long id, #Param("organizationId")long organizationId);
}
So I am just getting the error below when I try to use the main-replica. I have tried using the #UseDataSource annotation and AOP does actually intercept it. But, it still uses the read-replica.
java.sql.SQLSyntaxErrorException: UPDATE command denied to user 'read-replica-user'#'read replica IP' for table 'message'
What am I missing?
When you use #UseDataSource, it is working so it seems rules out any issues with implementation of aspect.
And When you #Transactional, it uses the secondary replica, regardless of your your AOP being invoked. My suspicion is by the TransactionInterceptor created by spring is invoked before your RouteDataSourceInterceptor. You can try the following:
Put a breakpoint in your aop method as well as a break point in org.springframework.transaction.interceptor.TransactionInterceptor.invoke method to see which one invokes first. You want your interceptor invoked first
If your interceptor is not invoked first, I would modify your interceptor to have high order as follows.
#Aspect
#Order(Ordered.HIGHEST_PRECEDENCE)
#Component
public class RouteDataSourceInterceptor {
I still don't understand how you are telling TransactionInterceptor to choose the DataSource you set in RouteDataSourceInterceptor. I have not used multi tenant setup but recently I came across a question which I helped to solve and I can see it is implementing AbstractDataSourceBasedMultiTenantConnectionProviderImpl. So I hope you have something similar. Not able to switch database after defining Spring AOP

mock.method call returns null after stubbing

I am trying to test using Mockito
my class under test is
#Service
public class DynatraceAPIServiceImpl implements DynatraceAPIService {
private String apiUrl = "someurl";
private String apiToken = "sometoken";
#Override
public CreateCustomMetricResponse createCustomMetric(CreateCustomMetricRequest request) throws MonitoringException {
logger.info("Inside create custom metric");
if (request == null) {
logger.error("create metric request is null");
throw new MonitoringException("Create metric request is null");
}
String metricId = DynatraceConstants.METRIC_ID;
String displayName = request.getDisplayName();
CreateCustomMetricResponse response = httpUtils.postCustomMetric(apiUrl + "/v1/timeseries/" + metricId, apiToken, request);
if (response == null) {
logger.error("Error in creating custom metric with name : " + displayName);
throw new MonitoringException("Error in creating custom metric with name : " + displayName);
}
logger.info("Custom metric : " + displayName + " is created successfully.");
return response;
}
}
and my Test class is :
#RunWith(MockitoJUnitRunner.class)
public class DynatraceAPIServiceImplTest {
#InjectMocks
DynatraceAPIServiceImpl dynatraceAPIServiceImpl;
#Mock
DynatraceHttpUtils httpUtilsMock;
#Mock
DynatraceMonitoringUtils monitoringUtilsMock;
#Test(expected = MonitoringException.class)
public void createCustomMetricGetsNonNullResponse() throws MonitoringException {
CreateCustomMetricRequest mockRequest = CreateCustomMetricRequest.builder()
.displayName(DISPLAY_NAME)
.types(new String[] {"test-type"})
.build();
CreateCustomMetricResponse response = CreateCustomMetricResponse.builder()
.displayName(DISPLAY_NAME)
.types(new String[] {"test-type"})
.timeseriesId(TIMESERIES_ID)
.build();
boolean val = true;
when(monitoringUtilsMock.isValidMetricIdValue(anyString())).thenReturn(val);
when(httpUtilsMock.postCustomMetric(API_URL + "/v1/timeseries/" + METRIC_ID, API_TOKEN, mockRequest)).thenReturn(response);
CreateCustomMetricResponse actualRespnose = dynatraceAPIServiceImpl.createCustomMetric(mockRequest);
//verify(httpUtilsMock, times(1)).postCustomMetric(anyString(), anyString(), any(CreateCustomMetricRequest.class));
//assertEquals(actualRespnose.getDisplayName(), DISPLAY_NAME);
}
}
Here, when I execute the tests, it always end up having the response value to be null in line
CreateCustomMetricResponse response = httpUtils.postCustomMetric(apiUrl + "/v1/timeseries/" + metricId, apiToken, request);
Even if I have used when() statement to return response as I have created, it is returning null.
Really appreciate if someone can let me know what is wrong here. Thanks.
That normally happens when the params your production code uses differ from the ones that you stubbed the call with, an easy way to find out is to write the test like this
when(httpUtilsMock.postCustomMetric(any(), any(), any())).thenReturn(response);
CreateCustomMetricResponse actualRespnose = dynatraceAPIServiceImpl.createCustomMetric(mockRequest);
verify(httpUtilsMock).postCustomMetric(API_URL + "/v1/timeseries/" + METRIC_ID, API_TOKEN, mockRequest);
If you do that, you'll get a nicer error showing the difference between what your code did and what you verified it for
A better approach in general is to use 'strict stubs' so if your code does anything different to what you stubbed the mock for you'll get a nice error telling you what, where and why

Mocking an ArrayList using PwerMock

i am trying to mock an arraylist as follows using Powermock
MockDao Class
PowerMockito.mockStatic(DailyReceiptsAndExceptionsDetailsDao.class);
PowerMockito.mockStatic(UtilityFunctions.class);
DailyReceiptsAndExceptionsExport dailyExceptionsExport = Mockito.mock(DailyReceiptsAndExceptionsExport.class);
List<DailyReceiptsAndExceptionsDetailsGridDto> resultList = getDailyExceptions(inputDto);
try{
PowerMockito.whenNew(DailyReceiptsAndExceptionsExport.class).withArguments(Mockito.any(DailyReceiptsAndExceptionsDetailsInputDto.class)).thenReturn(dailyExceptionsExport);
Mockito.when(DailyReceiptsAndExceptionsDetailsDao.getDailyReceiptsAndExceptions(Mockito.any(DailyReceiptsAndExceptionsDetailsInputDto.class))).thenReturn(resultList);
Mockito.when(UtilityFunctions.processReportSchedule(scheduleId, jobId,dailyExceptionsExport,(List<DailyReceiptsAndExceptionResultDTO>)Mockito.any(), null, null)).thenReturn(true);
}catch(Exception e){
}
I need to write tests for the following class.
public static Response getOutboundAvgCubeAndWeightUtilization(
#QueryParam("dc") String dc,
#QueryParam("asn") String asn,
#QueryParam("sortBy") String sort,
#QueryParam("isExport") boolean isExport,
#QueryParam("fileType") String fileType,
#QueryParam("scheduleId") BigDecimal scheduleId,
#QueryParam("jobId") BigDecimal jobId) {
ResponseDTO responseDto = new ResponseDTO();
DailyReceiptsAndExceptionsDetailsInputDto inputDto = new DailyReceiptsAndExceptionsDetailsInputDto ();
inputDto.setAsn(asn);
inputDto.setDc(dc);
inputDto.setSortBy(sort);
inputDto.setFileType(fileType);
inputDto.setExport(isExport);
String filePath = "";
try {
DailyReceiptsAndExceptionResultDTO resultDto = DailyReceiptsAndExceptionsDetailsBusinessManager.getInstance().manageDailyReceiptsAndExceptionsDetails(inputDto);
List<DailyReceiptsAndExceptionResultDTO> resultsList = new ArrayList<DailyReceiptsAndExceptionResultDTO>();
resultsList.add(resultDto);
if(scheduleId != null) {
boolean responseStatus = UtilityFunctions.processReportSchedule(scheduleId, jobId, new DailyReceiptsAndExceptionsExport(inputDto), resultsList, null,null);
responseDto.setResult(Boolean.toString(responseStatus));
return CommonUtil.convertResponseToJson(responseDto);
}
}
My tests class is as follows.
#Test
public void testGetOutboundAvgCubeAndWeightUtilization_4()
throws Exception {
String dc = "5854";
String asn = "*";
String sort = "SKU";
boolean isExport = false;
String fileType = "";
BigDecimal scheduleId = new BigDecimal(100);
BigDecimal jobId = new BigDecimal(100);
DailyReceiptsAndExceptionsDetailsInputDto inputDto = new DailyReceiptsAndExceptionsDetailsInputDto ();
inputDto.setAsn(asn);
inputDto.setDc(dc);
inputDto.setSortBy(sort);
inputDto.setFileType(fileType);
inputDto.setExport(isExport);
DailyReceiptsAndExceptionsDetailsMockDAO.mockgetDailyExceptions(inputDto, scheduleId, jobId);
Response result = DailyReceiptsAndExceptionsDetailsService.getOutboundAvgCubeAndWeightUtilization(dc, asn, sort, isExport, fileType, scheduleId, jobId);
String output = result.getEntity().toString();
assertEquals(true,output.contains("\"result\": \"true\""));
}
when iam running the test case, it was throwing error because, i think the mocking of the list is not correct.
Can anybody tell how to run this test scenario ....
Your mocks appear to be fine.
JUnit is failing the test because the line
assertEquals(true,output.contains("\"result\": \"true\""));
is failing: this means that your String output does not contain the text "result": "true"
Perhaps one way for you to figure out what is wrong is to either print out the value of output prior to the assertEquals() call or use a debugger to see what the value of output is.
As a side note, assertEquals(true, <condition>) is very verbose, you can use assertTrue(<condition>) instead.
According to your comment the test is simply failing. (AssertionErrors are JUnit's way of saying that your test failed.)
You could get a better error message if you use Hamcrest. Therefore you have to change the last two lines of your code:
assertThat(result.getEntity(), hasToString(containsString("\"result\": \"true\"")));
Add some static imports for org.hamcrest.MatcherAssert.assertThat and org.hamcrest.Matchers.*.
The new error message may help you finding the error.

pass authentication parameter in webservice

I am building a webservice server side. In my webservice, every client needs to pass their authentication parameter, via POST method in json format, for every request they make. Is passing parameter via post a good practice?
A guy told me, I should always use GET method to retrieve data; POST should be used for insertion only. If this is so, how am I going to pass the authentication param? One could be through URL and the other through header value. Which way should I use?
try to implement this web service. This web service permits to pass their authentication parameter through header value.
#WebService(serviceName="authentication")
public class WSAuthentication {
String name = null;
String password = null;
public WSAuthentication() {
super();
}
public WSAuthentication(String name, String password) {
this.name = name;
this.password = password;
}
private static String getData(WSAuthentication sec) {
System.out.println("********************* AUTHENTICATION ********************" + "\n" +
"**********USER: " + sec.name + "\n" +
"******PASSWORD: " + sec.password + "\n" +
"******************************** AUTHENTICATION ****************************");
return sec.name + " -- " + sec.password;
}
#WebMethod(operationName="security", action="authenticate")
#WebResult(name="answer")
public String security(#WebParam(header=true, mode=Mode.IN, name="user") String user, #WebParam(header=true, mode=Mode.IN, name="password") String password) {
WSAuthentication secure = new WSAuthentication(user, password);
return getData(secure);
}
}
And I use POST method for response. I hope help you.

Datanucleus JDO setting fields to null

In an attempt to find another issue, my tests came up with the following bit of code.
public class TestPersistance {
private static final PersistenceManagerFactory PMF = JDOHelper.getPersistenceManagerFactory("datanucleus.properties");
public static final PersistenceManager pm = PMF.getPersistenceManager();
static final TestUserDataDB ud = new TestUserDataDB();
public static void main(String args[])
{
TestPersistance tp = new TestPersistance();
tp.createData();
}
#Test public void createData()
{
assertTrue("Null machined id at start", ud.machineId != null);
pm.currentTransaction().begin();
try
{
pm.makePersistent(ud);
}
finally
{
pm.currentTransaction().commit();
}
assertTrue("Null machined id at end", ud.machineId != null);
}
}
where the second assert fails. ie. my object that I am asking to be persisted is being changed by the makePersistent call. The data is being stored in the database.
Any ideas? Can any one confirm this.

Why are you accessing fields directly ? Is the accessing class declared as PersistenceAware ? Well it isn't so you can't do that - use the getters.
What is "ud" object state before persist ? (transient?) what is it after persist ? (hollow?) What does the log say ? Chances are that it is in hollow state and then you access a field directly and it has no value (by definition, as per the spec) ... but since you didn't bother calling the getter it hasn't a chance to retrieve the value. And you likely also don't have "RetainValues" persistent property set
Suggest you familiarise yourself with the JDO spec and object lifecycle states
In some cases, it is necessary to access deserialized objects' attributes directly (i.e. if using GSON library for JSON serialization). In that case you can use:
MyClass copy = myPersistencyManager.detachCopy(myRetrievedInstance);
