Sping——MVC(参数传递练习)
作者:互联网
需求说明:
实现View到Controller的参数传递
1、在index.jsp,输入用户编码
2、点击提交按钮,页面跳转到success.jsp页面,并在该页面输出用户提交的编码
3、要求在控制台输出从前台获取的用户编码的值

代码实例:
导入相关架包:
新建index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>登录</title>
</head>
<body>
//创建form表单
<form action="/login.do" method="post">
账号:<input name="username" type="text" id="name">
密码:<input name="password" type="text" id="pwd">
<input type="submit" value="提交" >
</form>
</body>
</html>
配置springmvc.xml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:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="

<!--自动扫面上下文包-->
<context:component-scan base-package="cn.yyj.*"></context:component-scan>
<mvc:annotation-driven></mvc:annotation-driven>
<mvc:default-servlet-handler></mvc:default-servlet-handler>
<!--视图解析器-->
<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="UTF-8"></property>
<property name="maxUploadSize" value="10000000"></property>
</bean>
</beans>
创建跳转页面success.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>成功页面</title>
</head>
<body>
success
<br>
账号:${name}
密码:${pwd}
</body>
</html>
控制台测试
@RequestMapping("/login.do")
public ModelAndView login(String username,String password){
ModelAndView mv = new ModelAndView();
//接收页面传递过来的数据 明明是id
mv.addObject("pwd",password);
mv.addObject("name",username);//添加模型数据
System.out.println(username);
System.out.println(password);
//发送视图到success页面
mv.setViewName("success");//设置视图名
return mv;
}
结果:
标签:success,Sping,mv,参数传递,MVC,jsp,ModelAndView,password,页面 来源: https://blog.csdn.net/yangyingjian123/article/details/114980707
