如何解决Singleton EJB的初始化失败

Question

I have a java EE project that is executed in a Glassfish 4.1 container using Eclipse Mars, using EJB injection. I have a Singleton EJB that initialize or update the database when application start

@Startup
@Singleton
public class DatabaseUpdater {

    private static final Logger LOG = Logger.getLogger(DatabaseUpdater.class.getName());

   /**
    * Initializes database process
    */
    @PostConstruct
    public void initialize(UserVO userVO) {
        // ... initialize code
    }
}

The project is executed in Eclipse Mars, using Debug on Server option, and it was working good. However yesterday I just tried to do this to start project, and deployment process failed in Eclipse. This exception stack appears:

Someone knows how to fix this error? After this happen, the DAS of glassfish try again to deploy application, and eclipse generate several times deployment error messages (this only stop when I remove the resource in glassfish server and stop it)

The project is using maven to manage dependencies.

Answer 1

As specified in the docs :

The method on which the @PostConstruct annotation is applied MUST fulfill all of the following criteria

• The method MUST NOT have any parameters except in the case of EJB interceptors in which case it takes an InvocationC ontext object as defined by the EJB specification.
• The return type of the method MUST be void.
• The method MUST NOT throw a checked exception.
• The method on which PostConstruct is applied MAY be public, protected, package private or private.
• The method MUST NOT be static except for the application client.
• The method MAY be final.
• If the method throws an unchecked exception the class MUST NOT be put into service except in the case of EJBs where the EJB can handle exceptions and even recover from them.

Then change your method from

@PostConstruct
public void initialize(UserVO userVO) {
    // ... initialize code
}

to

@Inject
UserVO userVO

@PostConstruct
public void initialize() {
    // ... initialize code
}

and create a producer that will be responsible to provide the UserVo object to the injection points with the @Produces annotation.
