直接已知子类：

ServletActionRedirectResult

public class ServletRedirectResult
extends StrutsResultSupport
implements com.opensymphony.xwork2.util.reflection.ReflectionExceptionHandler

Calls the sendRedirect method to the location specified. The response is told to redirect the browser to the specified location (a new request from the client). The consequence of doing this means that the action (action instance, action errors, field errors, etc) that was just executed is lost and no longer available. This is because actions are built on a single-thread model. The only way to pass data is through the session or with web parameters (url?name=value) which can be OGNL expressions.

This result type takes the following parameters:

• location (default) - the location to go to after execution.
• parse - true by default. If set to false, the location param will not be parsed for Ognl expressions.
• anchor - Optional. Also known as "fragment" or colloquially as "hash". You can specify an anchor for a result.

This result follows the same rules from StrutsResultSupport.

Example:

 
 <!--
   The redirect URL generated will be:
   /foo.jsp#FRAGMENT
 -->
 <result name="success" type="redirect">
   <param name="location">foo.jsp</param>
   <param name="parse">false</param>
   <param name="anchor">FRAGMENT</param>
 </result>
