java.security.AccessControlException 对组件的 EJB 调用失败

【问题标题】：EJB Invocation failed on component by java.security.AccessControlExceptionjava.security.AccessControlException 对组件的 EJB 调用失败
【发布时间】：2015-01-18 11:17:17
【问题描述】：

我在 EJB Bean 中有一个方法

@Override
public void checkReqPermission(List<String> req, MyContext context) 
              throws AccessControlException, Exception
{
 if(notAllowed)
 throw new AccessControlException("Unauthorized Access : User is 
              not permitted to execute command(s)");
}else{
...}

另一方面，我需要捕获这个 ACE 以进一步执行语句。

当我调用这个方法时会发生什么？我在 server.log 中有很多异常跟踪

我不会在任何地方打印此异常跟踪。

这是什么意思？是否表示不允许访问该方法或我的自定义异常？

如果该方法不允许访问意味着我该如何使用这个ACE？ 或者它是我的自定义异常意味着如何在服务器日志中阻止此异常跟踪？

提前致谢:)。

【问题讨论】：

  • 你为什么不抛出你的自定义异常并处理它。为什么要抛出安全异常？
  • @Patton 我创建了新的自定义异常。现在它工作正常。

【解决方案1】：

您在日志中看到的消息是因为java.security.AccessControlException 是一个未经检查的异常（它是一个 RuntimeException）。 当从 ejb 方法抛出 java.lang.RuntimeException 时，容器将

  1. 回滚事务
  2. 丢弃 EJB Bean 实例
  3. 将javax.ejb.EJBException包裹的RuntimeException抛出到 客户。

在 JBoss 中，每个 EJBException 都会被记录。

当您知道您期望在您的客户端层中出现什么样的异常时，您必须展开 EJBException 以挖掘真正的原因，并在对用户有意义的情况下将其显示给用户。这类异常将是您定义的专用运行时异常（假设 AccessControlException 扩展了 RuntimeException）。

挖掘真正的原因是一个简单的方法：

Throwable unrollException(Throwable exception, Class<? extends Throwable> expected){
    
    while(exception != null && exception != exception.getCause()){
        if(expected.isInstance(exception)){
          return exception;
        }
        exception = exception.getCause();
    }
    return null;
}

在其他情况下，当从 EJB 方法抛出 java.lang.Exception 时，您显然必须使用 throws 关键字在方法的签名中声明它。容器将：

  1. 事务被提交
  2. 异常被重新抛出给客户端。

在 EJB 术语中，已检查的异常是 ApplicationException。该名称表明此异常意味着应用程序开发人员意识到的问题。
