Spring MVC页面重定向

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
  • jsp子文件夹下创建一个视图文件index.jspfinal.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 -

@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";
