@PostConstruct 拦截器与 @Named @ViewScoped 未调用

我仔细阅读了有关的文章拦截器 http://docs.jboss.org/weld/reference/1.0.0/en-US/html/interceptors.html在接缝/焊接文档中并实施了InterceptorBinding:

@InterceptorBinding
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD, ElementType.TYPE})
public @interface MyLog {}

and a Interceptor class:

@MyLog @Interceptor
public class ErpLogInterceptor implements Serializable
{
  @AroundInvoke
  public Object logMethodEntry(InvocationContext invocationContext) throws Exception
  {..}

  @PostConstruct
  public Object logPostConstruct(InvocationContext invocationContext) throws Exception
  {...}
}

不，我尝试激活拦截器@Named @ViewScoped bean:

@javax.inject.Named;
@javax.faces.bean.ViewScoped
public class MyBean implements Serializable
{
  @PostConstruct @MyLog
  public void init()
  {...}

  @MyLog public void toggleButton()
  {..}
}

如果我按下 JSF 页面上的按钮，该方法toggleButton被正确调用and拦截器方法logMethodEntry叫做。不过好像方法@PostConstruct（我感兴趣的）从来没有被我的班级拦截过。

这个问题似乎与Java EE 拦截器和 @ViewScoped bean https://stackoverflow.com/questions/12841351但实际上我的拦截器正在工作normal方法。

您应该设置返回类型@PostConstruct拦截器void not Object。 改变：

  @PostConstruct
  public Object logPostConstruct(InvocationContext invocationContext) throws Exception
  {...}

to:

  @PostConstruct
  public void logPostConstruct(InvocationContext invocationContext) throws Exception
  {...}
