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 -

  

配置文件

web.xml

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

dispatcher-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

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";
    }


}
