制作人：全心全意
创建spring的核心配置文件（springmvc.xml，可自定义名称）
<?xml version="1.0" encoding="UTF-8"?> <!-- 引入头文件开始 --> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> </beans> <!-- 引入头文件结束 -->
配置前端控制器（web.xml）
<!-- 配置前端控制器开始 --> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 加载springmvc.xml文件 --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> <!-- 启动加载 --> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.action</url-pattern> <!-- *.action：访问以action为结尾，由DispatcherServlet进行解析 /：所有地址，都由DispatcherServlet进行解析，不使用（例如，访问图片不可解析） /*：此处不正确的配置，会形成页面和解析器的死循环 --> </servlet-mapping> <!-- 配置前端控制器结束 -->
创建控制器
#===================User对象开始=======================================
package com.zq.bean;
public class User {
private String username;
private Integer age;
private Integer sex;
public User() {
}
public User(String username, Integer age, Integer sex) {
super();
this.username = username;
this.age = age;
this.sex = sex;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public Integer getSex() {
return sex;
}
public void setSex(Integer sex) {
this.sex = sex;
}
}
#===================User对象结束=======================================
#===================User1Controller开始=======================================
package com.zq.user;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
import com.zq.bean.User;
public class User1Controller implements Controller {
@Override
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
// 生成用户列表
List<User> users = new ArrayList<>();
for (int i = 1; i <= 20; i++) {
users.add(new User("username" + i, i, 0));
}
// 封装页面的地址和要传入页面的数据
ModelAndView modelAndView = new ModelAndView();
modelAndView.addObject("users", users); // 向页面传入内容
// 跳转的页面，默认为转发
modelAndView.setViewName("list.jsp");
// modelAndView.setViewName("redirect:list.jsp"); //重定向
return modelAndView;
}
}
#===================User1Controller结束=======================================
#===================User2Controller开始=======================================
package com.zq.user;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.HttpRequestHandler;
import com.zq.bean.User;
public class User2Controller implements HttpRequestHandler {
@Override
public void handleRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// 生成用户列表
List<User> users = new ArrayList<>();
for (int i = 1; i <= 20; i++) {
users.add(new User("username" + i, i, 0));
}
// 封装页面的地址和要传入页面的数据
request.setAttribute("users", users); // 向页面传入内容
// 跳转的页面，默认为转发
request.getRequestDispatcher("list.jsp").forward(request, response);
}
}
#===================User2Controller结束=======================================
配置控制器（springmvc.xml）
<!-- 配置控制器开始 --> <bean id="user1Controller" name="/user1Controller.action" class="com.zq.user.User1Controller"></bean> <!-- 配置控制器结束 -->
配置控制器映射器
<!-- 配置控制器映射器开始 --> <!-- 两种控制器映射器 org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping：将bean的name作为url进行查找，也就是handler必须配置name属性 org.springframework.web.servlet.handler.SimpleUrlHandlerMapping：可以配置多个url能够访问 --> <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean> <!-- 配置控制器映射器结束 -->
配置控制器适配器
<!-- 配置控制器适配器开始 --> <!-- 两种控制器适配器 org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter：Controller实现的是Controller接口 org.springframework.web.servlet.mvc.HttpRequestHandlerAdapter：Controller实现的是HttpRequestHandler接口，例如User2Controller --> <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean> <!-- 配置控制器适配器结束 -->
配置视图解析器：
<!-- 配置视图解析器开始 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"></bean> <!-- 配置视图解析器结束 -->
配置测试页面
#=================list.jsp页面开始===================================
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>用户列表</title>
</head>
<body>
<table width="60%" align="center" border="1" cellpadding="5">
<tr>
<th>用户名</th>
<th>年龄</th>
<th>性别</th>
</tr>
<c:forEach var="sn" items="${ users }">
<tr>
<td align="center">${ sn.username }</td>
<td align="center">${ sn.age }</td>
<td align="center">${ sn.sex }</td>
</tr>
</c:forEach>
</table>
</body>
</html>
#=================list.jsp页面结束===================================
注意：pom.xml所有spring的插件版本号都应一致
#===================pom.xml开始================================================
