As of now whole process is handled by JTA but i want to commit Scrutiny class instantantly which suggest job has just started and at end want to update the same.
You should remove the UserTransaction injection from your DAO generic object and handle the transaction within Scrutiny bean, annotating it with TransactionManagement.
Your bean code should become this:
#Stateless
#TransactionManagement(value=TransactionManagementType.BEAN)
public class Scrutiny {
private static final Logger log = Logger.getLogger(Scrutiny.class.getName());
#Inject
private UserTransaction utx;
public Scrutiny() {
System.out.println("Scrutiny");
}
#Inject
StatusDao statusDao;
public JobStatus insertNewRecord(JobName jName) {
log.info("insertNewRecord:" + jName);
try {
utx.begin(); <--- Here i want to begin
statusDao.create(js);
utx.flush();
utxcommit(); <--- Here i want to Commit
} catch (Exception e) {
log.warning("insertNewRecord:" + e);
}
}
With these changes, your DAO should continue to work using container managed transactions, while your specific bean can control the transaction as desired.

Unit Testing Rest Services with Spring Boot and JUnit

I have a basic SpringBoot app. using Spring Initializer, JPA, embedded Tomcat, Thymeleaf template engine, and package as an executable JAR file. I've defined this Rest method to get a User
#GetMapping(path = "/api/users/{id}",
consumes = "application/json",
produces = "application/json")
public ResponseEntity<User> getUser
(HttpServletRequest request,
#PathVariable long id) {
User user = checkAccess(request, id);
return ResponseEntity.ok(user);
}
I've created this Junit to test it
#ContextConfiguration(classes={TestSystemConfig.class})
#RunWith(SpringRunner.class)
#WebMvcTest(UserResourceController.class)
public class UserResourceControllerTests {
#Autowired
private MockMvc mvc;
#MockBean
private UserResourceController UserResourceController;
#Test
public void getUser() throws Exception {
mvc.perform(get("/api/users/1")
.with(user("pere.peris#gmail.com").password("password"))
.contentType(APPLICATION_JSON))
.andExpect(status().isOk());
}
}
But I got this error when I run the test:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.IllegalArgumentException: Name for argument type [long] not available, and parameter name information not found in class file either.

The reason is because you are mocking your controller. This is not necessary when you have #WebMvcTest(UserResourceController.class)
This should work.
#ContextConfiguration(classes={TestSystemConfig.class})
#RunWith(SpringRunner.class)
#WebMvcTest(UserResourceController.class)
public class UserResourceControllerTests {
#Autowired
private MockMvc mvc;
#Test
public void getUser() throws Exception {
mvc.perform(get("/api/users/1")
.with(user("pere.peris#gmail.com").password("password"))
.contentType(APPLICATION_JSON))
.andExpect(status().isOk());
}
}

ApplicationContext Exception in Test with #WebMvcTest

I Have an Spring Boot Application (1.5.10.RELEASE) which contains a main (SpringBootApplication) like this:
#SpringBootApplication
#Configuration
#EntityScan(basePackages = { "db.modell", "db.modell.base" })
#ComponentScan(basePackages = { "de.gui.test" })
public class SpringBootConsoleApplication {
public static void main(String[] args) throws Exception {
SpringApplication.run(SpringBootConsoleApplication.class, args);
}
}
and two REST controllers like the following:
#RestController
#RequestMapping("/as")
public class AController {
#Autowired
private ARepository aRepository;
#RequestMapping(method = RequestMethod.GET)
public ResponseEntity<Collection<A>> getAs() {
return new ResponseEntity<>(orgtFarbeRepository.findAll(), HttpStatus.OK);
}
#RequestMapping(value = "/{id}", method = RequestMethod.GET)
public ResponseEntity<A> getA(#PathVariable long id) {
A a = ARepository.findOne(id);
if (party != null) {
return new ResponseEntity<>(ARepository.findOne(id), HttpStatus.OK);
} else {
return new ResponseEntity<>(null, HttpStatus.NOT_FOUND);
}
}
}
Furthermore I have a single test like this:
#RunWith(SpringRunner.class)
#WebMvcTest(AController.class)
public class AControllerTest {
#Autowired
private MockMvc mvc;
#MockBean
private ARepository ARepository;
#Test
public void firstTest() throws Exception {
A a = new aFarbe();
a.set....
when(ARepository.findAll()).thenReturn(Collections.singleton(a));
mvc.perform(
get("/as")
.accept(MediaType.APPLICATION_JSON_UTF8_VALUE)
)
.andExpect(status().isOk());
}
}
The repositories look like this:
public interface ARepository extends CrudRepository<A, Long>
{
Collection<A> findAll();
}
public interface BRepository extends CrudRepository<B, Long>
{
Collection<B> findAll();
}
A and B them self are JPA annotated classes. The whole application contains access to a database..
Furthermore I have a Service like this:
#Service
public class XService {
private static final Logger LOGGER = LoggerFactory.getLogger(XService.class);
#Autowired
private ARepository aRepository;
#Autowired
private BRepository bRepository;
...
}
The XService is not used via #Autowire or so (Just need to remove that):
So I try to run the AControllerTest I get the following error:
java.lang.IllegalStateException: Failed to load ApplicationContext at

My assumption is that during the test more context is started than it should. The question is how can I prevent that? Which means only to start the context for the AControler and nothing more? I thought that based on the #WebMvcTest(AController.class) it should be limited already which looks like that it was not the case...
The referenced answer does not really answered my question but a in the context a hint gave me the solution. This means in consequence to add the following to my test:
so I have to add #OverrideAutoConfiguration(enabled=true):
#RunWith(SpringRunner.class)
#WebMvcTest(OrgtFarbenController.class)
#OverrideAutoConfiguration(enabled=true)
public class AControllerTest {
...
}

spring webclient unit test with mockito

I'm trying to write a test for my controller (which has an autowired field pageModelService)
here is my test class:
#RunWith(MockitoJUnitRunner.class)
public class PageModelControllerTest {
#Mock
private PageModelService pageModelService;
#InjectMocks
private PageModelController pageModelController;
private WebTestClient client;
#Before
public void setup() {
client = WebTestClient.bindToController(pageModelController).build();
}
}
I can't create the client, it tells me it can't autowire pageModelService
any idea

Spring restful service test case fail HTTP status is 500

I want to implement test case for spring restful web services which return a json
MY controller test class is :
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(classes = {WebAppContext.class,JpaTestConfiguration.class
})
#WebAppConfiguration
public class DominProfileRestControllerTest {
private MockMvc mockMvc;
#Autowired
private WebApplicationContext webApplicationContext;
private MediaType contentType = new MediaType(MediaType.APPLICATION_JSON.getType(),
MediaType.APPLICATION_JSON.getSubtype(),
Charset.forName("utf8"));
#Before
public void setUp() {
mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}
#Test
public void testGetDomainProfile() throws Exception {
String profileId = domainProfile.getId().toString();
System.out.print("testing restful"+profileId);
mockMvc.perform(get("/service/domainprofile/get/{id}", profileId) )
.andExpect(status().isOk())
.andExpect(content().contentType(contentType))
.andExpect(jsonPath("$.city", is("Chandigrah")));
/* mockMvc.perform(get("/service/domainprofile/get/{id}",profileId).accept(MediaType.TEXT_PLAIN))
.andExpect(status().isOk())
.andExpect(content().contentType("text/plain;charset=ISO-8859-1"))
.andExpect(content().string("hello Prashant"));
*/
}
My Controller class Is :
#RestController
#RequestMapping("/service/domainprofile")
public class DominProfileRestController {
#Autowired
private JpaDomainProfileRepository jpaDomainProfileRepository;
#RequestMapping(value = "/get/{id}", method = RequestMethod.GET)
public DomainProfileResource getDomainProfile(#PathVariable String id) {
JpaDomainProfile domainProfile = jpaDomainProfileRepository.findOne(Long.valueOf(id));
DomainProfileResource domainProfileResource = new DomainProfileResource();
System.out.println("domainProfile.getCity()*************" + domainProfile.getCity());
System.out.println("domainProfile.getAddress()*************" + domainProfile.getAddress());
domainProfileResource.setCity(domainProfile.getCity());
domainProfileResource.setAddress(domainProfile.getAddress());
// return new ResponseEntity<DomainProfileResource>(domainProfileResource, HttpStatus.OK);
return domainProfileResource;
// return domainProfile;
}
}
When I run test case I got An error while we got values in domainprofile.city and domainprofile.address.
Error Is :
java.lang.AssertionError: Status
Expected :200
Actual :500
It Is Working Fine When I return a plain text
can you do this
mockMvc.perform(get("/service/domainprofile/get/{id}", profileId) )
.andDo(print());
this will print the full response with exception , now if you see HttpMessageNotWritableException which was the issue I was facing , you should try to serialize your object using jackson and see if it works (spring internally uses Jackson ). For example , If any of your fields are null the Serialization will fail.
