I'm using primefaces 5.1.7 with wildfly and have a Problem when multiple pictures are uploaded at the same time.
I have multiple instances of a ViewScoped bean which are created (tested using breakpoints in #PostConstruct)
xhtml:
<h:form enctype="multipart/form-data" prependId="true">
<p:fileUpload fileUploadListener="#{myBean.handleFileUpload}"
mode="advanced" auto="true" update="list"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/" multiple="true"/>
...
bean:
import javax.faces.view.ViewScoped;
#Named
#ViewScoped
public class MyBean implements Serializable {
...
public void handleFileUpload(FileUploadEvent event) {
...
}
}
This happens about 75% of the time but sometimes everything is just fine. Any idea how i can avoid those multiple instances?
a possible solution... (not tested!!):
Your Session scoped CDI Bean:
...
import javax.enterprise.context.SessionScoped
...
#SessionScoped
public class MySession implements Serializable {
public void doSomeWork(...) {
...
}
}
And your Conversation scoped CDI Bean:
...
import javax.inject.Named
import javax.enterprise.context.ConversationScoped
...
#Named
#ConversationScoped
public class MyBean implements Serializable {
#Inject
private Conversation conversation;
#Inject
private MySession mySession;
#PostConstruct
public void init() {
conversation.begin();
}
public void handleFileUpload(FileUploadEvent event) {
...
mySession.doSomeWork(...);
...
}
public void remove() {
conversation.end();
}
}
And your Controller:
#Named
public class MyController implements Serializable {
#Inject
private MyBean myBean;
public String doSomethingAfterAllUploadsAreFinished() {
...
myBean.remove();
return "SUCCESS";
}
}

public class UserController {
#Autowired
private UserRepository userRepository;
#GetMapping
public List<User> findAllUsers() {
return (List<User>) userRepository.findAll();
}
}
This is the code of the controller class
you specified the url in the #RequestMapping("...") annotation
#RequestMapping("url")
public class UserController {
#Autowired
private UserRepository userRepository;
#GetMapping
public List<User> findAllUsers() {
return (List<User>) userRepository.findAll();
}
and add the #RestController annotation above the class
I am trying to mock abstract class which is called within another class. I mocked the abstract class however mocked abstract class is not being injected.
Any advise on how to mock the abstract class and inject it?
public abstract class MyAbstractClass {
public HelloBean getHelloBean(HelloBean bean){
return bean;
}
}
public class MyBusinessClass extends MyAbstractClass {
public String getBusinessData(){
HelloBean bean = getHelloBean(new HelloBean()) //I want to mock this method while testing getBusinessData()
}
}
My JUnit Class
public class MyBusinessClass {
private MyAbstractClass myAbstractClass = mock(MyAbstractClass.class);
private MyBusinessClass myBusinessClass = mock(MyBusinessClass.class);
#Test
public String getBusinessData(){
when(myAbstractClass.getHelloBean(any(HelloBean.class))).doReturn(new HelloBean());
myBusinessClass.getBusinessData();
}
}
By using Inject Mock it works
Here the test class is
#SpringBootTest
#AutoConfigureMockMvc
public class HelloServiceMockTest {
#InjectMocks
MyBusinessClass myBusinessClass;
#Mock
MyAbstractClass myAbstractClass;
#Mock
HelloBean helloBean;
#Test
public void getBusinessData(){
when(myAbstractClass.getHelloBean(helloBean)).thenReturn(new HelloBean());
myBusinessClass.getBusinessData();
Assert.assertEquals("ggg",myBusinessClass.getBusinessData());
}
}
HelloBean class is
public class HelloBean {
public String get()
{
return "ggg"; }
}
MyBusinessClass is
public class MyBusinessClass extends MyAbstractClass {
public String getBusinessData(){
HelloBean bean = getHelloBean(new HelloBean()); //I want to mock this method while testing getBusinessData()
return bean.get();
}
}
I want to test my implementation for AttributeConverter using #DataJpaTest.
test code
#RunWith(SpringRunner.class)
#DataJpaTest
#AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
class FooRepositoryTest {
#Autowired
private FooRepository repository;
#Test
void getPojoTest(){
FooEntity fooEnity= repository.findById("foo");
FooPojo fooPojo = fooEntity.getJsonPojo()
//some assertion
}
}
Entity
#Entity
#Data
#NoArgsConstructor
public class FooEntity{
....
#Column(columnDefinition= "JSON")
#Convert(converter = FooConverter.class)
private FooPojo data;
....
}
Attribute Converter
public class FooConverter implements AttributeConverter<FooPojo, String> {
#Autowired
private ObjectMapper mapper;
#SneakyThrows
#Override
public String convertToDatabaseColumn(FooPojo attribute) {
return mapper.writeValueAsString(attribute);
}
#SneakyThrows
#Override
public FooPojo convertToEntityAttribute(String dbData) {
return mapper.readValue(dbData, FooPojo.class);
}
}
with my code above, when I run getPojoTest(), the #autowired OjbectMapper in Converter is null. When I try the same test with #SpringBootTest instead, it works just fine. I wonder is there any walk-around to use #DataJpaTest and ObjectMapper together.
A better alternative compared to creating your own ObjectMapper is adding the #AutoConfigureJson annotation:
#DataJpaTest
#AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
#AutoConfigureJson
public void FooRepositoryTest {
}
This is also what #JsonTest uses.
From Docs:
#DataJpaTest can be used if you want to test JPA applications. By
default it will configure an in-memory embedded database, scan for
#Entity classes and configure Spring Data JPA repositories. Regular
#Component beans will not be loaded into the ApplicationContext.

I would like to be able for Mockito to perform a custom action when a given void method is called.
Say I have the following code:
#Autowired
private ProfileService profileService;
#Autowired
private ProfileDao profileDao;
private List<Profile> profiles;
#Before
public void setup() {
Mockito.when(profileDao.findAll()).thenReturn(profiles);
Mockito.when(profileDao.persist(any(Profile.class))).thenAddProfileToAboveList...
}
#Configuration
public static class testConfiguration {
#Bean
public ProfileDao ProfileDao() {
return mock(ProfileDao.class);
}
}
Say I want to add a Profile instance to the profiles list. Can Mockito do that? If so how?
Use Mockito.doAnswer.
doAnswer(new Answer() {
public Object answer(InvocationOnMock invocation) {
// make the changes you need here
}})
.when(mock).someMethod();
