如何获得HTTP状态代码为REST服务骡子

我采取了以下作为参考： - https://github.com/daveEason/mule-example-spring-security/blob/master/src/main/app/mule-config.xml

现在的问题，只要我打的网址： - http://localhost:8083/myrest ...我得到以下异常： -

我不知道它为什么产生这样的例外..

但是，如果我从代码中删除异常块，打http://localhost:8083/myrest它工作正常，并要求用户名和密码预期，并产生预期的结果..

但我不知道它为什么产生当我使用异常块代码例外.. 其实我使用异常块的目的是获取和在不同的情况

有在玩两样东西在这里：

异常，由新泽西州的资源

这种异常必须要处理抛出由一个或多个自定义JAX-RS异常处理程序，通过一个或多个jersey:exception-mapper元素注册到jersey:resources。
例外通过mule-ss:http-security-filter

这些异常是由骡子JAX-RS的范围之外抛甩，所以他们必须处理由catch-exception-strategy元素，正如你在你的问题一样。

有了这种错误处理的组合应该为你提供你所需要的。

控制不同的HTTP状态

来检索HTTP代码，您可以使用过滤器并在流程中引发异常。下面一个例子：

<message-filter throwOnUnaccepted="true"> 
    <message-property-filter pattern="message.inboundProperties['http.status'] >= 400" /> 
</message-filter>
