以下示例显示如何编写一个简单的基于Web的重定向应用程序，这个应用程序使用重定向将http请求传输到另一个页面。
- 基于Spring MVC - Hello World实例章节中代码，创建创建一个名称为 PageRedirection 项目。
- 在
com.ktao.controller包下创建一个Java类WebController。 - 在
jsp子文件夹下创建一个视图文件index.jsp，final.jsp。 - 最后一步是创建所有源和配置文件的内容并导出应用程序，如下所述。
完整的项目代码，如下所示 -
配置文件
web.xml

dispatcher-servlet.xml

控制器
WebController.java
webpackage com.ktao.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; @Controller public class WebController { @RequestMapping(value = "/index",method = RequestMethod.GET) public String index(){ return "index"; } @RequestMapping(value = "/redirect",method = RequestMethod.GET) public String redirect(){ return "redirect:finalPage"; } @RequestMapping(value = "/finalPage",method = RequestMethod.GET) public String finalPage(){ return "final"; } }
视图
index.jsp
