1.新建module，名称叫02_springmvc
2.新建文件夹web
3.点击确定，就会看到如下图，idea自动给我们创建了web.xml
这时候web文件夹多一个小点点的标识
4.pom.xml引入相关依赖
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.2.0.RELEASE</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.2.1-b03</version>
<scope>provided</scope>
</dependency>
</dependencies>
5.配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
<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_4_0.xsd"
version="4.0">
<!-- 前端控制器 -->
<servlet>
<servlet-name>springDispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springDispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
<!-- /和/*都是拦截所有请求，/*的范围更大，会拦截jsp文件 -->
</servlet-mapping>
</web-app>
6.新增springmvc.xml
此时springmvc.xml 为原始xml，没有任何bean数据
7.创建controller文件，TestController
public class TestController implements Controller {
@Override
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
ModelAndView mv = new ModelAndView();
mv.addObject("name", request.getParameter("name"));
mv.setViewName("test");
return mv;
}
}8.创建web/WEB_INF/pages/test.jsp页面
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<html>
<body>
<h1>页面参数:${name}</h1>
</body>
</html>9.配置springmvc.xml
<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"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 设置逻辑视图名的前缀 --> <property name="prefix" value="/WEB-INF/pages/"/> <!-- 设置逻辑视图名的后缀 --> <property name="suffix" value=".jsp"/> </bean>
<bean name="/test" class="com.china.controller.TestController"/>
</beans>10.运行，结果如下
11.使用注解版
@Controller
public class Test2Controller {
@RequestMapping("/test2")
public ModelAndView test(@RequestParam("name") String name){
ModelAndView mv = new ModelAndView();
mv.addObject("name", name);
mv.setViewName("test");
return mv;
}
}12.springmvx.xml开启controller组件扫描
<!--开启controller组件扫描-->
<context:component-scan base-package="com.china.controller"/>13.运行结果如下
