所有已实现的接口:

Serializable

public class PrivilegedActionException
extends Exception

This exception is thrown by doPrivileged(PrivilegedExceptionAction) and doPrivileged(PrivilegedExceptionAction, AccessControlContext context) to indicate that the action being performed threw a checked exception. The exception thrown by the action can be obtained by calling the getException method. In effect, an PrivilegedActionException is a "wrapper" for an exception thrown by a privileged action.

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

toString

public String toString()

从类复制的说明: Throwable

Returns a short description of this throwable. The result is the concatenation of:

• the Class#getName() of the class of this object
• ": " (a colon and a space)
• the result of invoking this object's Throwable.getLocalizedMessage() method

If getLocalizedMessage returns null, then just the class name is returned.

覆盖:

toString 在类中 Throwable

返回:

a string representation of this throwable.
