重定向和转发分为：重定向到页面，转发到页面，重定向到处理器方法和转发到处理器方法
1.重定向到页面
准备一个控制器
@Controller public class RedirectAndForword { //重定向到页面 @RequestMapping("/first") public String doFirst(Model model){ model.addAttribute("msg","username"); return "redirect:/success.jsp"; } }
配置文件：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <context:component-scan base-package="demo11RedirectAndForword"></context:component-scan> <!--视图解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/"></property> <property name="suffix" value=".jsp"></property> </bean> <!--注解驱动--><!--<mvc:annotation-driven/>--> </beans>
成功页面上：success.jsp

测试的时候直接方法处理器方法的ResultMapping就可以
2.转发到页面
//转发到页面 @RequestMapping("/second") public String doSecond(Model model){ /*model.addAttribute("msg","username");*/ return "success"; }
其他和第一种一样
3.重定向到处理器方法和转发到处理器方法
//重定向到处理器 @RequestMapping("/third") public String doThird(Model model){ model.addAttribute("msg","username"); return "redirect:/first"; } //转发到处理器 @RequestMapping("four") public String doFour(Model model){ model.addAttribute("msg","username"); return "forward:/second"; }
