public class InvocationTargetException
extends ReflectiveOperationException

InvocationTargetException is a checked exception that wraps an exception thrown by an invoked method or constructor.

As of release 1.4, this exception has been retrofitted to conform to the general purpose exception-chaining mechanism. The "target exception" that is provided at construction time and accessed via the getTargetException() method is now known as the cause, and may be accessed via the Throwable#getCause() method, as well as the aforementioned "legacy method."

方法详细资料

getTargetException

返回:

the thrown target exception (cause of this exception).

getCause

public Throwable getCause()

Returns the cause of this exception (the thrown target exception, which may be null).

覆盖:
