看网上的教程ssm三大框架整合都是一堆xml配置文件，我今天出一个教程，SSM三大框架只需要一个xml配置文件，

无需 :mybatis-config.xml, db.properties，spring-mvc.xml , log4j.properties。

**示例环境基于：**

spring5.2.9,下载地址：[https://repo.spring.io/libs-release-local/org/springframework/spring/5.2.9.RELEASE/][https_repo.spring.io_libs-release-local_org_springframework_spring_5.2.9.RELEASE]

Mybatis:3.5.6,下载地址：[https://github.com/mybatis/mybatis-3/releases][https_github.com_mybatis_mybatis-3_releases]

以上包均为目前最新版本

**1，User.java实体类**

package com.ssm.entity;
    
    public class User {
        private String loginid;
        private String loginname;
        private String sex;
        private String mobile;
    
        public String getLoginid() {
            return loginid;
        }
    
        public void setLoginid(String loginid) {
            this.loginid = loginid;
        }
    
        public String getLoginname() {
            return loginname;
        }
    
        public void setLoginname(String loginname) {
            this.loginname = loginname;
        }
    
        public String getSex() {
            return sex;
        }
    
        public void setSex(String sex) {
            this.sex = sex;
        }
    
        public String getMobile() {
            return mobile;
        }
    
        public void setMobile(String mobile) {
            this.mobile = mobile;
        }
    
        @Override
        public String toString() {
            StringBuilder sb = new StringBuilder();
            sb.append(getClass().getSimpleName());
            sb.append(" [");
            sb.append("loginid=").append(loginid);
            sb.append(", loginname=").append(loginname);
            sb.append(", sex=").append(sex);
            sb.append(", mobile=").append(mobile);
            sb.append("]");
            return sb.toString();
        }
    
    
    }

**2，UserDao.java 接口类**

package com.ssm.dao;
    
    import java.util.List;
    import com.ssm.entity.User;
    
    /*
        接口类中定义接口即可，无需自己去写接口实现类，Mybatis会做这个工作
        接口类中所有方法默认均为public作用域，所以可以不写public权限修饰符
    */
    public interface UserDao {
    	int selectCount();
    	List<User> selectAllUser();
    }

**3，UserDao.xml 映射文件**

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE mapper
      PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
      "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
      
      <mapper namespace="com.ssm.dao.UserDao">
    	<select id="selectCount" resultType="int">
    		select count(*) from t_users;
    	</select>
    	
    	<select id="selectAllUser" resultType="com.ssm.entity.User">
    		select * from t_users;
    	</select>
    </mapper>

**4，UserController.java 控制类**

package com.ssm.controller;
    import java.util.List;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.servlet.ModelAndView;
    
    import com.ssm.dao.UserDao;
    import com.ssm.entity.User;
    
    @Controller
    public class UserController {
    	
    	@Autowired
    	UserDao user;
    	
    	@GetMapping("/index")
        public String index() {
    		System.out.printf("到了这里代表你已经成功了！,共有记录：%d条",user.selectCount());
            return "Hello World!";
        }
    	
    	@RequestMapping("/userlist")
    	public ModelAndView  userlist() {
    		ModelAndView mv =new ModelAndView();
    		List<User> userlist =user.selectAllUser();
    		//类似于request.setAttribute("userlist",userlist);
    		mv.addObject("userlist",userlist);
    		mv.setViewName("index");
    		return mv;
    	}
    
    }

**5，Spring.xml （spring+springmvc+mybatis整合配置文件）**

<?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"
           xmlns:tx="http://www.springframework.org/schema/tx"
           xsi:schemaLocation="http://www.springframework.org/schema/beans

    	<mvc:annotation-driven >
    		<mvc:message-converters register-defaults="true">
    	          <bean class="org.springframework.http.converter.StringHttpMessageConverter">
    	            <property name="supportedMediaTypes" value="text/html;charset=UTF-8"/>
    	          </bean>
    	   </mvc:message-converters>
    	</mvc:annotation-driven>
    	
    	
        
    	
    	
        
    
    	
    	
    	<context:component-scan base-package="com.ssm.controller" />
    	
    	
    	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" 
    	      id="internalResourceViewResolver">
            
    	    <property name="prefix" value="WEB-INF/pages/" />
            
    	    <property name="suffix" value=".jsp" />
           </bean> 
    	 
    
     
    
    	
    	
    	
    
       
        
        <bean id="jdbcDataSource" class="org.apache.commons.dbcp.BasicDataSource"  destroy-method="close">
            <property name="driverClassName" value="com.mysql.jdbc.Driver" />
            <property name="url" value="jdbc:mysql://127.0.0.1:3306/itqs" />
            <property name="username" value="root" />
            <property name="password" value="123456" />
        </bean>
        
     
       
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            
            <property name="dataSource" ref="jdbcDataSource"></property>
            
            
            <property name="mapperLocations" value="classpath:com/ssm/dao/*.xml" />
        </bean>
        
        
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            
            
            
             <property name="basePackage" value="com.ssm.dao" />
        </bean>
    
        
        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="jdbcDataSource"></property>
        </bean>
        
        
        <tx:annotation-driven transaction-manager="transactionManager"/>
    	
    </beans>

**6，web.xml配件文件（这个必须的）**

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
             xmlns="http://java.sun.com/xml/ns/javaee" 
             xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
             http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
    	
      <display-name>SSM</display-name>
     
    
    <servlet>
        <servlet-name>Spring-MVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            
            <param-value>classpath:spring.xml</param-value>
        </init-param>
    </servlet>
    
    <servlet-mapping>
        <servlet-name>Spring-MVC</servlet-name>
        
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
    </web-app>

**7，index.jsp测试文件**

<%@ page contentType="text/html;charset=UTF-8" %>
    <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
    
    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="UTF-8">
    <title>Insert title here</title>
    <style>
    	table{border-collapse:collapse; font-size:14px;}
    	table td,th{ border:1px solid #98bf10;border-collapse:collapse; padding:5px 8px;}
    	table td{ text-align:center; padding:3px;}
    	table th{background-color:#A7C942;color:#FFF;font-size:15px;}
    	table .alt{ background-color:#EAF2D3;}
    	tr.change:hover{ background-color:#00FF00 }
    </style>
    
    </head>
    <body>
    	Tips: Hello!这是一个基于SSM整合框架的测试<br><br>
    	<div id="all-div" >
    		<table width="500;" border="1">
    			<thead>
    				<th>登录id</th>
    				<th>名字</th>
    				<th>性别</th>
    				<th>手机</th>
    			</thead>
    			<tbody>
    				<c:forEach var="users" items="${userlist}">
    					<tr class="change">
    						<td>${users.loginid}</td>
    						<td>${users.loginname}</td>
    						<td>${users.sex}</td>
    						<td>${users.mobile}</td>
    					</tr>
    				</c:forEach>
    			</tbody>
    		</table>
    	</div>
    </body>
    </html>
