如何配置在Jboss 7中使用EntityListeners？

Question

我已在JBoss 7中添加org.eclipse.persistence模塊。我不能使用EntityListeners。
如果我從實體中刪除@EntityListeners(IDInterceptor.class)，則堅持操作即可。
在實體存在之前，我必須做一些操作。

如果我測試插入方法的DAO與Junit,EntityListeners是工作。

我用：JBoss 7，Spring 3.5和JPA 2.0 (EcliplseLink 2.5.0)

讓我知道，我怎麼能在我的web應用程序使用EntityListeners與JBoss 7？

InsuType.java

@Entity 
@TableGenerator(name = "INSUTYPE_GEN", table = "ID_GEN", pkColumnName = "GEN_NAME", valueColumnName = "GEN_VAL", pkColumnValue = "INSUTYPE_GEN", allocationSize = 10) 
@EntityListeners(IDInterceptor.class) 
public class InsuType implements Serializable { 
    @Id 
    @GeneratedValue(strategy = GenerationType.TABLE, generator = "INSUTYPE_GEN") 
    private String id; 
    private String name; 
    //getter and setter 
} 

IDInterceptor.java

public class IDInterceptor { 
    @PrePersist 
    public void onPrePersist(Object obj) { 

    } 

    //other function 
} 

InsuTypeDAO.java

@Repository("InsuTypeDAO") 
public class InsuTypeDAO implements IInsuTypeDAO { 
    @PersistenceContext 
    protected EntityManager em; 

    @Transactional(propagation = Propagation.REQUIRED) 
    public InsuType insert(InsuType insuType) throws DAOException { 
     em.persist(insuType); 
     return insuType; 
    } 
} 

如果我使用@EntityListeners(IDInterceptor.class)，我收到以下錯誤

Answer 1

最後，我得到一個解決方案，它是EntityListener類必須擴展DescriptorEventAdapter。 即使EntityListener需要注入彈簧組件，只需嘗試如下。 確保對彈簧組件/ bean使用static屬性和setter property。

@Component 
public class IDInterceptor extends DescriptorEventAdapter { 
    private static SomeSpringBean someSpringBean; 

    @Autowired(required = true) 
    @Qualifier("SomeSpringBean") 
    public void setSomeSpringBean(SomeSpringBean bean) { 
     someSpringBean = bean; 
    } 

    @Override 
    public void preInsert(DescriptorEvent event) { 

    } 
}
