i am trying to write test case for below controller its working fine,But problem is when i run unit test case then its showing null pointer exception in controller class at (LOGGER.info("========>request is------>" + objectMapper.writeValueAsString(basBaaisnEvcIdRequest));
can some one help me please how can i resolve this problem

The setUp() of Junit is not called and therefore a NullPointerException is thrown when the test methods try to acces the BankAccount object.
What is wrong with my setUp()?
Here is the test code:
package my_package;
import static org.junit.jupiter.api.Assertions.*;
import org.junit.Before;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
class BankAccountTest {
private BankAccount acc;
#Before
public void setUp(){
acc = new BankAccount(100);
}
#Test
void testDeposit() {
acc.deposit(50);
assertEquals(acc.getBalance(), 50);
}
#Test
void testWithdraw() {
acc.withdraw(50);
assertEquals(acc.getBalance(), 25);
}
#Test
void testWithdrawLimit() {
assertFalse(acc.withdraw(10000));
assertEquals(100, acc.getBalance());
assertTrue(acc.withdraw(1));
assertEquals(acc.getBalance(),99);
}
}
and here is the application code:
package my_package;
public class BankAccount {
private int balance;
public BankAccount(int i) {
balance=i;
}
public BankAccount() {
balance=0;
}
public void deposit(int amount) {
balance += amount;
}
public boolean withdraw(int amount) {
boolean allow = balance >= amount;
if(allow) {
balance -= amount;
}
return allow;
}
public int getBalance() {
return balance;
}
}
The stacktrace:

Replace #Before annotation with #BeforeEach
Explanation
The setUp method uses #Before annotation which is from JUnit4.
But your tests are written for JUnit 5 (the org.junit.jupiter.api.Test is used on test methods)
From JUnit5 user guide:
#Before and #After no longer exist; use #BeforeEach and #AfterEach instead

How to convert Part to Blob, so I can store it in MySQL?
(1 answer)
Closed 6 years ago.
I want to upload a file and save it to mysql database. thus far, I am able to upload the file, print its detail. However, when I attempt to store it in the database via a helper class everything except for the ID become null. Can you take a look and let me know what I am missing? Also, let me know if you see anything that I should change/modify as code enhancement.
Uploading the file using JSF/Primefaces:
<h:form enctype="multipart/form-data">
<p:growl id="messages" showDetail="true" />
<p:fileUpload value="#{fileUploadView1.file}" mode="simple"/>
<p:commandButton value="Submit" ajax="false" actionListener="#{fileUploadView1.upload}" />
</h:form>
FileBean:
#ManagedBean
#SessionScoped

#Inject

FacesContext.getCurrentInstance().addMessage(null, message);
input = file.getInputstream();
fileName = file.getFileName();
fileSize = file.getSize();
System.out.println("filesize3 " + file.getSize());
fileController.uploadFile(file);
}
}
}
FileController:

private FileDbUtil1 fileDbUtil;

fileController isn't getting injected.
Use #Inject private FileController1 fileController.
BalusC is right on his comment.
I have the following definition for PersonDTO:
public class PersonDTO
{
private String id
private String firstName;
private String lastName;
private String maritalStatus;
}
Here is a sample record :
{
"id": 1,
"firstName": "John",
"lastName": "Doe",
"maritalStatus": "married"
}
Now, John Doe gets divorced. So I need to send a PATCH request to this URL:
http://localhost:8080/people/1
With the following request body:
{
"maritalStatus": "divorced"
}
I cannot figure out how to do it. Here is what I tried so far:
// Create Person
PersonDTO person = new PersonDTO();
person.setMaritalStatus("Divorced");
// Create HttpEntity
final HttpEntity<ObjectNode> requestEntity = new HttpEntity<>(person);
// Create URL (for eg: localhost:8080/people/1)
final URI url = buildUri(id);
ResponseEntity<Void> responseEntity = restTemplate.exchange(url, HttpMethod.PATCH, requestEntity, Void.class);
Here are the problems with the above:
1) As I am setting only MaritalStatus, the other fields would all be null. So if I print out the request, it will look like this:
{
"id": null,
"firstName": "null",
"lastName": "null",
"maritalStatus": "married" // I only need to update this field.
}
Does that mean that I have to a GET before I do a PATCH?
2) I am getting the following stack trace:
08:48:52.717 ERROR c.n.d.t.s.PersonServiceImpl - Unexpected Exception :

Appreciate any pointers from folks who have written client applications to consume a Restful webservice using Spring's RestTemplate.
For completeness, let me also state that we use SpringDataRest for our backend restful webservices.
SGB
I solved this problem just adding a new HttpRequestFactory to my restTemplate instance. Like this
RestTemplate restTemplate = new RestTemplate();
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setConnectTimeout(TIMEOUT);
requestFactory.setReadTimeout(TIMEOUT);
restTemplate.setRequestFactory(requestFactory);
For TestRestTemplate, add
#Autowired
private TestRestTemplate restTemplate;
#Before
public void setup() {
restTemplate.getRestTemplate().setRequestFactory(new HttpComponentsClientHttpRequestFactory());
}
PS: You will need add httpClient component in your project
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.4.1</version>
</dependency>
For cases where RestTemplate is built from a RestTemplateBuilder, constructor for the custom RestClient can be written as,
public PersonRestClient(RestTemplateBuilder restTemplateBuilder) {
this.restTemplate = restTemplateBuilder.requestFactory(new HttpComponentsClientHttpRequestFactory()).build();
}
Also, the org.apache.httpcomponents.httpclient dependency needs to added to pom.
I have added the below code in the java file. It worked for me.
String url="Your API URL";
RestTemplate restTemplate = new RestTemplate();
HttpClient httpClient = HttpClientBuilder.create().build();
restTemplate.setRequestFactory(new
HttpComponentsClientHttpRequestFactory(httpClient));
HttpHeaders reqHeaders = new HttpHeaders();
reqHeaders.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<String> requestEntity = new HttpEntity<String>(requestJson, reqHeaders);
ResponseEntity<String> responseEntity=restTemplate.exchange(url, HttpMethod.PATCH,
requestEntity, String.class);
Also, need to add the below dependency in the pom.xml file.
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
</dependency>
For me solved by adding below line:
restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());
I created a generic method to do this when there are linked resources involved:
public void patch(M theEntity, Integer entityId, String linkName, URI linkUri) {
ObjectMapper objectMapper = getObjectMapperWithHalModule();
ObjectNode linkedNode = (ObjectNode) objectMapper.valueToTree(theEntity);
linkedNode.put(linkName, linkUri.getPath());
HttpEntity<ObjectNode> requestEntity = new HttpEntity<>(linkedNode);
restTemplate.exchange(uri + "/" + entityId, HttpMethod.PATCH, requestEntity, Void.class);
}
private ObjectMapper getObjectMapperWithHalModule() {
if(objectMapperHal == null) {
objectMapperHal = new ObjectMapper();
objectMapperHal.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
objectMapperHal.registerModule(new Jackson2HalModule());
}
return objectMapperHal;
}
Feel free to look at an implementation of this example at my full jal+json implementation
If you have an older spring version than 3.1.0, then you don't have the PATCH method in the HttpMethods. You can still use HttpClient from apache. Here is a short example on how I did it:
try {
//This is just to avoid ssl hostname verification and to trust all, you can use simple Http client also
CloseableHttpClient httpClient = HttpClientBuilder.create().setSSLContext(new SSLContextBuilder().loadTrustMaterial(null, TrustAllStrategy.INSTANCE).build())
.setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE).build();
HttpPatch request = new HttpPatch(REST_SERVICE_URL);
StringEntity params = new StringEntity(JSON.toJSONString(payload), ContentType.APPLICATION_JSON);
request.setEntity(params);
request.addHeader(org.apache.http.HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE);
request.addHeader(HttpHeaders.ACCEPT, MediaType.APPLICATION_JSON_VALUE);
//You can use other authorization method, like user credentials
request.addHeader(HttpHeaders.AUTHORIZATION, OAuth2AccessToken.BEARER_TYPE + " " + accessToken);
HttpResponse response = httpClient.execute(request);
String statusCode = response.getStatusLine().getStatusCode();
} catch (Exception ex) {
// handle exception here
}
The equivalent of this, with RestTemplate would be:
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.add("Authorization", OAuth2AccessToken.BEARER_TYPE + " " + accessToken);
final HttpEntity<String> entity = new HttpEntity<String>(JSON.toJSONString(payload), headers);
RestTemplate restTemplate = new RestTemplate();
try {
ResponseEntity<String> response = restTemplate.exchange(REST_SERVICE_URL, HttpMethod.PATCH, entity, String.class);
String statusCode = response.getStatusCode();
} catch (HttpClientErrorException e) {
// handle exception here
}
Also, make sure the payload only contains the values you need to change, and make sure you are sending the request to the right URL. (this can be in some cases something ending like /api/guest/{id} )
this will work if verified answer dose works
#Bean
public RestTemplate restTemplate() {
RestTemplate restTemplate = new RestTemplate();
HttpClient httpClient = HttpClientBuilder.create().build();
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory(httpClient);
restTemplate.setRequestFactory(requestFactory);
return restTemplate;
}
WebClient offers a modern alternative to the RestTemplate with efficient support for both sync and async, as well as streaming scenarios. You can implement this with WebClient.
Configure WebClient
#Configuration
public class WebConfig {
public WebClient.Builder webClientBuilder() {
return WebClient.builder();
}
}
Then you can call method
//Constructor Injection
public YourClassName(WebClient.Builder webClientBuilder) {
this.webClientBuilder = webClientBuilder;
}
webClientBuilder.build()
.patch()
.uri("http://localhost:8081/api/v1/customers/{id}", id)
.contentType(MediaType.APPLICATION_JSON)
.retrieve()
.bodyToMono(Void.class)
.block();

I have a RESTeasy service thats running on JBOSS AS 7, that is trying to create a connection with a local database (mysql server).
The data source is properly defined in the JBOSS management and connects fine (a JSF app can connect fine with it and it can modify the database), however when I try to connect in my RESTeasy service, it gives me a nullPointerException and I can't seem to figure out why. kumonobs is the database in question. The error occurs in the persist method, which is called through a post request. Any help would be much appreciated, if any additional information is needed please ask!

Found the solution, instead of the Annotation to the datasource use:
String strDSName = "java:jboss/datasources/thenamehere";
ctx = new InitialContext();
dataSource = (javax.sql.DataSource) ctx.lookup(strDSName);
