Struts2 项目中自定义返回结果类型

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

	
		
		
			
				
		
		
			/WEB-INF/test/test.jsp
			/WEB-INF/jsp/error.jsp
			/WEB-INF/jsp/error.jsp
		
		
		
			
			 
		
	

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";
	}
}

访问 项目名称（/斜线不能少）加 nsfw/user/user_defineResult.do 就会跳转到测试页面
