struts2 自定义结果集类型

先实现一个类去继承StrutsResultSupport，baseAction继承了ActionSupport

public class SysResultAction extends StrutsResultSupport{
  @Override
  protected void doExecute(String finalLocation, ActionInvocation invocation) throws Exception {
    HttpServletRequest request = ServletActionContext.getRequest();
    HttpServletResponse response = ServletActionContext.getResponse();
    System.out.println("finalLocation="+finalLocation);
    System.out.println("(BaseAction)invocation.getAction()="+(baseAction)invocation.getAction());
    System.out.println("进入了 SysResultAction ...");
    //eg redirect
    String baseURl = request.getContextPath()  +  finalLocation.replace("WEB-INF/", "");
    String RedirectUrl  = baseURl.substring(0,baseURl.lastIndexOf("/")+1);
    response.sendRedirect( RedirectUrl + "test_TAction.do" );
  }
}

在修改struts2核心配置配置文件

<!-- 配置全局结果及异常映射 配置文件包-->
<package name="base-default" extends="struts-default" >
  <!-- 自定义结果集类型  -->
  <result-types>
    <result-type name="myRedirectResult" class="cn.terry.commons.exception.SysResultAction"></result-type>
  </result-types>		
  <!-- 全局结果集 -->
  <global-results>
    <result name="MRR" type="myRedirectResult">/WEB-INF/test/test.jsp</result>
    <result name="sysError">/WEB-INF/jsp/error.jsp</result>
    <result name="input">/WEB-INF/jsp/error.jsp</result>
  </global-results>
  <!-- 全局错误结果集 -->
  <global-exception-mappings>
    <exception-mapping result="sysError" exception="cn.terry.commons.exception.SysException"></exception-mapping>
    <exception-mapping result="input" exception="java.lang.Exception"></exception-mapping> 
  </global-exception-mappings>
</package>

在添加action

public class userAction extends baseAction {
  // 自定义返回结果类型定义,会输出定义的内容
  public String defineResult() throws Exception {
    return "MRR";
  }
}
