Im using Spring Social in my application:
<spring.framework.version>3.2.0.RELEASE</spring.framework.version>
<hibernate.version>4.1.9.Final</hibernate.version>
<commons-dbcp.version>1.4</commons-dbcp.version>
<org.springframework.social-version>1.1.0.BUILD-SNAPSHOT</org.springframework.social-version>
<org.springframework.social.facebook-version>1.1.0.BUILD-SNAPSHOT</org.springframework.social.facebook-version>
<org.springframework-version>3.2.1.RELEASE</org.springframework-version>
<org.springframework.security.crypto-version>3.1.3.RELEASE</org.springframework.security.crypto-version>
When I apply
private final Facebook facebook;
#Inject
public SearchController(Facebook facebook) {
this.facebook = facebook;
}
To my HomeController:
#Controller
public class HomeController {
private final Facebook facebook;
#Inject
public HomeController(Facebook facebook) {
this.facebook = facebook;
}
private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
/**
* Simply selects the home view to render by returning its name.
*/
#RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Model model) {
return "home";
}
}
The injection works like intented and I can get information from facebook. However, when I apply it to one of my other Cotrollers like this one
#Controller
#Transactional
#RequestMapping(value = "/search")
public class SearchController {
private static final Logger logger = LoggerFactory.getLogger(SearchController.class);
private final Facebook facebook;
#Inject
public SearchController(Facebook facebook) {
this.facebook = facebook;
}
#PersistenceContext
private EntityManager entityManager;
...
I getting this error:

My guess is that I can't inject facebook to a Controller with annotation #Transactional?
CGlib has one important restriction: the target class must provide a default constructor.
If you use property-based injection instead of constructor-based injection, the problem will go away.
I just created an empty default constructor to deal with this.
If you are using Lombok in your code, then you can just add the following annotation to get rid of this error:
#NoArgsConstructor
public class SearchController {

Please help me understand where i am making the mistake
Also if i move the resolver factory definition to a public method inside that same class its working perfectly
Reason for the NullPointerException
Although not explicitly mentioned in the question the provided stacktrace reveals that the service is "run" within a unit test.
Furthermore, the stack trace reveals, that the OsgiContext is used, which does not provide an implementation of the ResourceResolverFactory.
Since no ResourceResolverFactory is registered within the mock OSGi context, the #Reference can not be injected upon service registration and activation. When the ResourceResolverFactory is then called in the activate method the reference is null and therefore the NullPointerExceptionis thrown.
Proposed Solution
Therefore, I would advise to use the excellent AemContext which is provided by the wcm.io aem-mock framework or at least the SlingContext provided by sling-mocks.
The unit test would look like this:
public class MyUnitTest {
#Rule
public AemContext context;
#Test
public void someTest() {
MyTest service = context.registerInjectActivateService(new MyTest());
[... additional test code ...]
}
}
Since the AemContext already has a functional ResourceResolverFactory (mock) registered, the unit test code does not have to create a mock and register it. When the registerInjectActivateService() method is called a new instance of the MyTest class is instantiated and the referenced ResourceResolverFactory is injected.
Additional Note
Please do not create service-wide ResourceResolvers. This is a bad practice. ResourceResolver should be short-lived. That means that they are only used for a few "operations" (like reading a resource) and then discarded.
The best way to do this is to use the try-with-resource statement like this:
public class MyTest {
private static final SERVICE_NAME = "MyTestService";
private static final Map<String, Object> authenticationInfo = Collections.singletonMap(ResourceResolverFactory.SUBSERVICE, SERVICE_NAME);
#Reference
private ResourceResolverFactory resourceResolverFactory;
public void someMethod() {
try (ResourceResolver resolver = getResourceResolver()) {
[... use resolver to do stuff in JCR ...]
}
}
private ResourceResolver getResourceResolver() {
try {
return resourceResolverFactory.getServiceResourceResolver(authenticationInfo);
} catch (LoginException cause) {
throw new IllegalStateException("Unable to obtain ResourceResolver!", cause)
}
}
}
I chose to create a separate method to create the ResourceResolver to avoid cluttering someMethod() with exception handling. But that is obviously something that can be changed.
Since administrative ResourceResolver are deprecated I also chose to use a service ResourceResolver. To use those you need to create a service user mapping. You can find out more about this in the documentation.
Please note that creating the resolver inside of Acivate method is anti-pattern. Your service might be called by multiple threads in parallel, and that these calls can be processed in parallel.
When we do write or read a resource then JCR session apply internal lock, which prevents multiple sessions to work in parallel on the very same session.
The best way to avoid this issue is to create resolver inside a method which you override.
#Override
performSomeOperation(){
final ResourceResolver resolver;
try {
resolver = resolverFactory.getAdministrativeResourceResolver(null);
} catch (LoginException e) {
LOG.error("error resolving resource resolver", e);
return;
}
}
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 {
...
}
The persistence API uses JTA managed transactions which is configured in persistence.xml.
EntitymanagerProducer.java
#PersistenceContext( unitName = "PRO" )
EntityManager proEm;
#pro
#Produces
public EntityManager createProEntityManager () {
return this.proEm;
}
The above produced EntityManager could be injected into any #Stateless bean with qualifier #Pro as below,
#Stateless
#Local( OutRepositoryBeanLocal.class )
#Remote( OutRepositoryRemote.class )
#LocalBean
#TransactionAttribute( TransactionAttributeType.MANDATORY )
public class OutRepositoryBean implements OutRepositoryBeanLocal, OutRepositoryRemote {
#Inject
#Pro
private EntityManager entityManager;
#Inject
OutRepository outRepository;
/**
*
*/
#PostConstruct
private void init () {
this.outRepository.setEntityManager( this.entityManager );
}
The above piece of code works seemlessly with no error. But while delegating the job to #Dependent subclasses problem arises,
OutRepository.java
#Dependent
public class OutRepository extends BaseService< Out, Long > {
public OutRepository() {
// TODO Auto-generated constructor stub
}
#Override
protected Class< Out > t () {
return Out.class;
}
public List< Out > getOuts ( Long proId, String Out) {
CriteriaBuilder builder = this.entityManager.getCriteriaBuilder(); <= NPE
CriteriaQuery< Out > criteriaQuery = builder.createQuery( t() );
Root< Out > endPointConfig = criteriaQuery.from( t() );
criteriaQuery.select( endPoint );
TypedQuery< Out > query = this.entityManager.createQuery( criteriaQuery );
return query.getResultList();
}
Whereas the BaseService.java is an abstract class containing generic crud methods.
BaseService.java
#Dependent
public abstract class BaseService< T, I extends Serializable > implements BaseEntity< T, I > {
protected abstract Class< T > t ();
#PostConstruct
protected abstract void init ();
public PersistenceUnitUtil persistenceUnitUtil;
public EntityManager entityManager;
#TransactionAttribute( TransactionAttributeType.MANDATORY )
#Override
public T save ( T t ) {
this.entityManager.persist( t );
return t;
}
While outRepsitory.save() is called there is no problem in transaction everything works great. Yet while outRepository.getOuts(Long proId,String Out), Following exception occurs

Thanks.
There is no Inject annotation in BaseService
Should be like you have it done in OutRepositoryBean
#Inject #Pro
public EntityManager entityManager;
I've got a problem with EJB/Glassfish. I'm working on a client-server application in which the client creates an entity object and must send it to the server application, which must persist the entity in its database. I've choose to use session beans to communicate with the server.
I've implemented some simple cases in which a method in the session bean takes as input a string or an int and it works fine. The problem arises when I try to give an entity object as input.
I report my entity class:
#Entity
public class Example implements Serializable {
private static final long serialVersionUID = 1L;
#Id
String nome;
public void setNome(String nome) {
this.nome = nome;
}
public String getNome() {
return nome;
}
Here my session bean:
#Stateless
public class GestoreLibreriaRemoto implements GestoreLibreriaRemotoRemote {
#Override
public String getProva(Example prova) {
return prova.getNome();
}
Here my client application:
public class GestoreLibreriaLocale {
public static void assegnaCategoriaACopia(CopiaUtente copia, Categoria categoria) throws
public void prova() {
GestoreLibreriaRemotoRemote gestore = lookupGestoreLibreriaRemotoRemote();
Example example = new Example();
prova.setNome("hodor");
System.out.println(gestore.getProva(example));
}
private GestoreLibreriaRemotoRemote lookupGestoreLibreriaRemotoRemote() {
try {
Context c = new InitialContext();
return (GestoreLibreriaRemotoRemote) c.lookup("java:global/ServerMDB/ServerMDB-ejb/GestoreLibreriaRemoto");
} catch (NamingException ne) {
Logger.getLogger(getClass().getName()).log(Level.SEVERE, "exception caught", ne);
throw new RuntimeException(ne);
}
}
In my main class I simply call GestoreLibreriaLocale.prova() and i get the following error:
java.lang.reflect.InvocationTargetException

The error log continues, I don't report the whole log but if you need it I can post it.
Please help me, I'm working on it from days without resolving it.
Thanks for the attention,
Francesco
This seems to be a bug in the current Java versions (e.g. 1.7.0_55 and 1.8.0_05), have a look at this issue: GLASSFISH-21047
To make it work, install either an older or a newer Java version (e.g. 1.7.0_051 or 1.8.0_020).

Exception inside CORBA when accessing a remote bean
I have two Service classes which implement the same interface
ServiceClass1
#Service
public class ServiceClass1 implements ItemsService{
#Autowired
Class1DaoImpl class1Dao;
#Transactional
public List<Class1> getAllItems() {
return class1Dao.getAllItems();
}
ServiceClass2
#Service
public class ServiceClass2 implements ItemsService{
#Autowired
Class2DaoImpl class2Dao;
#Transactional
public List<Class2> getAllItems() {
return class2Dao.getAllItems();
}
And this is the controller class
#Controller
public class IndexController {
#Autowired
ServiceClass1 serviceClass1;
#Autowired
ServiceClass1 serviceClass2;
............
.....
}

I did some google-ing and can't seem to find any solid answer to why am I getting this error?
You need to autowire against the interface type, not the class type, i.e.
#Autowired
ItemsService serviceClass1;
If you have multiple beans that implement ItemsService, then autowiring isn't really appropriate. Consider using #Resource instead:
#Resource(name="serviceClass1")
ItemsService serviceClass1;
#Resource(name="serviceClass2")
ItemsService serviceClass1;
