我从 @PostConstruct 带注释的 init 方法中收到此警告

Nis 18, 2014 2:46:10 PM com.sun.faces.vendor.WebContainerInjectionProvider getAnnotatedMethodForMethodArr 警告：JSF1047：方法 'public void com.revir.managed.bean.PickListBean.init() throws java.lang.Exception' 标记为'javax.annotation.PostConstruct' 注释不能声明任何已检查的异常。此方法将被忽略。

所以我的方法被忽略了，我该怎么做才能解决这个问题？

throws Exception从 init 方法中删除。用于try catch防止抛出任何异常。删除异常声明后，编译器将向您显示可能引发的任何异常，因此请在此处添加 try catch。
