UndeclaredThrowableException

public class UndeclaredThrowableException
extends RuntimeException

java.lang.Object
   ↳ java.lang.Throwable
     ↳ java.lang.Exception
       ↳ java.lang.RuntimeException
         ↳ java.lang.reflect.UndeclaredThrowableException


如果其调用处理程序的方法调用 invoke方法抛出一个检查异常( Throwable不可分配给 RuntimeExceptionError ),而该分配不能分配给方法的 throws子句中声明的任何异常类型, throws代理实例上的方法调用抛出在代理实例上调用并分派给调用处理程序。

一个UndeclaredThrowableException实例包含调用处理程序抛出的未声明的已检查异常,并且可以使用getUndeclaredThrowable()方法检索它。 UndeclaredThrowableException扩展了RuntimeException ,所以它是一个未检查的异常,它包装了一个检查的异常。

从版本1.4开始,此异常已进行了改进,以符合通用异常链接机制。 现在可以在施工时提供并通过getUndeclaredThrowable()方法访问的“调用处理程序抛出的未声明的已检查异常”现在称为原因 ,可以通过getCause()方法以及上述“传统方法“。
