Spring-mvc数据响应ModelAndView形式详解
Spring-mvc数据响应ModelAndView形式详解
Springmvc中ModelAndView形式有很多
。
提示：以下是本篇文章正文内容，下面案例可供参考
一、配置内部资源视图解析器
<!--Controller的组件扫描-->
<context:component-scan base-package="com.itheima">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!--配置内部资源视图解析器-->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- /jsp/success.jsp -->
<property name="prefix" value="/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
二、使用步骤
1.controller代码
代码如下（示例）：
@Controller
public class UserController {
@RequestMapping("/quick2")
public ModelAndView save2(){
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName("success");
modelAndView.addObject("username","ldz");
return modelAndView;
}
@RequestMapping("/quick3")
//注入方法参数
public ModelAndView save3(ModelAndView modelAndView){
modelAndView.setViewName("success");
modelAndView.addObject("username","ldz");
return modelAndView;
}
@RequestMapping("/quick4")
public String save4(Model model){
model.addAttribute("username","ldz");
return "success";
}
@RequestMapping("/quick5")
public String save5(HttpServletRequest request){
request.setAttribute("username","ldz");
return "success";
}
2.读入数据
代码如下（示例）：
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h1>Success! ${
username} </h1>
</body>
</html>
Model：用于封装数据 View：用于展示数据
