从JAX-RS中的另一个ExceptionMapper调用ExceptionMapper [英] Call ExceptionMapper from another ExceptionMapper in JAX-RS

问题描述

在我的RESTEasy应用程序中，我得到一个java.lang.reflect.UndeclaredThrowableException，因为正在从一个未在throws子句中声明该异常的方法中抛出一个检查异常. 所以我在写UndeclaredThrowableExceptionMapper. UndeclaredThrowableException包装了真正的异常；我调用e.getCause()进行检索.
然后可以扔掉它还是以某种方式查找适当的ExceptionMapper来处理它?<​​/p>

In my RESTEasy application I'm getting a java.lang.reflect.UndeclaredThrowableException, because a checked exception is being thrown from a method that doesn't declare the exception in the throws clause.
So I'm writing an UndeclaredThrowableExceptionMapper. The UndeclaredThrowableException wraps the real exception; I call e.getCause() to retrieve it.
Can I then throw it or somehow look up the proper ExceptionMapper to handle it?

推荐答案

您可以尝试在UndeclaredThrowableExceptionMapper类中添加@Context javax.ws.rs.ext.Providers字段/属性.
然后使用Providers.getExceptionMapper(Class)查找要使用的真实异常映射器.

You can try adding a @Context javax.ws.rs.ext.Providers field/property to your UndeclaredThrowableExceptionMapper class.
Then use Providers.getExceptionMapper(Class) to look up the real exception mapper you want to use.
