如何解决 Singleton EJB 的初始化失败
How to solve a Initialization Failed for Singleton EJB
我有一个 java EE 项目，该项目使用 EJB 注入在 Eclipse Mars 的 Glassfish 4.1 容器中执行。我有一个单例 EJB，它在应用程序启动时初始化或更新数据库
@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
}
}
该项目在 Eclipse Mars 中执行，使用 Debug on Server 选项，并且运行良好。然而昨天我只是试图这样做来启动项目，并且部署过程在 Eclipse 中失败了。此异常堆栈出现：

有人知道如何解决这个错误吗？发生这种情况后，glassfish 的 DAS 再次尝试部署应用程序，eclipse 多次生成部署错误消息（这仅在我删除 glassfish server 中的资源并停止它时停止）
该项目正在使用 maven 来管理依赖项。
如the docs中所述：
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.
然后从
改变你的方法
@PostConstruct
public void initialize(UserVO userVO) {
// ... initialize code
}
到
@Inject
UserVO userVO
@PostConstruct
public void initialize() {
// ... initialize code
}
并创建一个 生产者，它将负责向带有 @Produces 注释的注入点提供 UserVo 对象。
