如果你使用的是 Intellij IDEA，请查看：

SSM的配置流程详细的写了出来，方便很少接触这个框架的朋友使用，文中各个资源均免费提供！

一.创建web项目（eclipse）

File-->new-->Dynamic Web Project (这里我们创建的项目名为SSM)

下面是大致目录结构

二. SSM所需jar包。

三.整合开始

1.mybatis配置文件（resource/mybatis/SqlMapConfig.xml）

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
</configuration>

2.Dao，mybatis整合spring，通过spring管理

SqlSessionFactory、mapper代理对象

（resource/spring/applicationContext-dao.xml）

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
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-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">


<context:property-placeholder location="classpath:*.properties" />

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
destroy-method="close">
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="driverClassName" value="${jdbc.driver}" />
<property name="maxActive" value="10" />
<property name="minIdle" value="5" />
</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="dataSource" ref="dataSource" />

<property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" />
</bean>

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.mapper" />
</bean>
</beans>

这里用的是阿里的连接池，当然也可以用c3p0，个人建议用阿里

3. 所有的实现类都放到spring容器中管理。由spring创建数据库连接池，并有spring管理实务。

（resource/spring/applicationContext-service.xml）

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
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-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">


<context:component-scan base-package="com.service"/>
</beans>

配置spring管理实务

（resource/spring/applicationContext-trans.xml）

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
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-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">

<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

<property name="dataSource" ref="dataSource" />
</bean>

<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>

<tx:method name="save*" propagation="REQUIRED" />
<tx:method name="insert*" propagation="REQUIRED" />
<tx:method name="add*" propagation="REQUIRED" />
<tx:method name="create*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="find*" propagation="SUPPORTS" read-only="true" />
<tx:method name="select*" propagation="SUPPORTS" read-only="true" />
<tx:method name="get*" propagation="SUPPORTS" read-only="true" />
</tx:attributes>
</tx:advice>

<aop:config>
<aop:advisor advice-ref="txAdvice"
pointcut="execution(* com.service.*.*(..))" />
</aop:config>
</beans>

4. Springmvc整合spring框架，由springmvc管理controller

（resource/spring/springmvc.xml）

<?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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

<context:component-scan base-package="com.controller" />

<mvc:annotation-driven />

<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>

5. 2中加载的属性配置文件（dbconfig.properties）

根据自己的数据库更改用户名密码以及库

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?characterEncoding=utf-8
jdbc.username=root
jdbc.password=123456

6. 配置log4j

（log4j.properties）

log4j.rootLogger=error,CONSOLE,A
log4j.addivity.org.apache=false
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Threshold=error
log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd HH\:mm\:ss} -%-4r [%t] %-5p %x - %m%n
log4j.appender.CONSOLE.Target=System.out
log4j.appender.CONSOLE.Encoding=gbk
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.A=org.apache.log4j.DailyRollingFileAppender
log4j.appender.A.File=${catalina.home}/logs/FH_log/PurePro_
log4j.appender.A.DatePattern=yyyy-MM-dd'.log'
log4j.appender.A.layout=org.apache.log4j.PatternLayout
log4j.appender.A.layout.ConversionPattern=[FH_sys] %d{yyyy-MM-dd HH\:mm\:ss} %5p %c{1}\:%L \: %m%n

(log4j.xml)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration PUBLIC "-//APACHE//DTD LOG4J 1.2//EN" "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

<appender name="console" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{yyyy HH:mm:ss} %-5p %c - %m%n" />
</layout>
</appender>

<logger name="com">
<level value="error" />
</logger>

<logger name="org.springframework.core">
<level value="error" />
</logger>
<logger name="org.springframework.beans">
<level value="error" />
</logger>
<logger name="org.springframework.context">
<level value="error" />
</logger>
<logger name="org.springframework.web">
<level value="error" />
</logger>
<logger name="org.springframework.jdbc">
<level value="error" />
</logger>
<logger name="org.mybatis.spring">
<level value="error" />
</logger>
<logger name="java.sql">
<level value="error" />
</logger>

<root>
<priority value="error" />
<appender-ref ref="console" />
</root>
</log4j:configuration>

SSM框架整合完成，至于mybatis逆向工程生成的mapper.xml和pojo请放到第一张图的目录下

注：逆向工程是根据数据库表反向生成pojo以及mapper.xml，所以，请先自动在数据库配置好user表。逆向工程得配置在下面得链接里面有详细注释。

测试数据库表（User）

private String id;

private String username;

private String password;

private String company;

private Integer age;

private Integer sex;

根据类型创建表即可

逆向工程项目我会贴出链接，解压导入改路径运行main方法就会自动生成了，注意配置生成的路径

逆向工程链接：链接：https://pan.baidu.com/s/1QvSskH2UEC6EQF7MgVDOAQ 密码：t2pc

到这里项目整合完成，接下来是测试！

UserController.java

package com.controller;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.pojo.User;
import com.service.UserService;
@Controller
@RequestMapping("/user")
public class UserController {
@Resource(name="userService")
private UserService userService;
/**
* 根据id查询
*/
@RequestMapping(value="/queryById")
public ModelAndView queryById(HttpServletRequest request){
ModelAndView mv = new ModelAndView();
String id = request.getParameter("id");
try{
User var = userService.findById(id);
mv.setViewName("index");
mv.addObject("var", var);
} catch(Exception e){
e.printStackTrace();
}
return mv;
}
}

UserService.java

package com.service;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.mapper.UserMapper;
import com.pojo.User;
@Service("userService")
public class UserService {
@Resource
private UserMapper dao;
/*
* 通过id获取数据
*/
public User findById(String id)throws Exception{
return (User)dao.selectByPrimaryKey(id);
}
}

补上之前漏掉得web.xml配置

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
<!-- <init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param> -->
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<!-- <servlet>
<servlet-name>taotao-manager</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
contextConfigLocation不是必须的，如果不配置contextConfigLocation， springmvc的配置文件默认在：WEB-INF/servlet的name+"-servlet.xml"
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SSM</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping> -->
<servlet>
<servlet-name>springMvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springMvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>

为节省篇幅，更快的搭建成功，这里只写了一个方法，根据id查询数据

WebContent/index.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>查询用户</title>
</head>
<body>
<form action="user/queryById.do" method="post">
输入要查询的id:<input type="text" name="id" value="123456"/>
<button type="submit">提交</button>
</form>
</body>
</html>

WebContent/WEB-INF/jsp/index.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%@page import="com.pojo.*"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
<style type="text/css">
.td td{
width: 100px;
}
.table{
text-align: center;
margin: 0 auto;
}
</style>
</head>
<body>
<%
User user = ((User)request.getAttribute("var"));
%>
<table class="table">
<tr class="td">
<td>ID</td>
<td>用户名</td>
<td>密码</td>
<td style="width: 200px">公司</td>
<td>年龄</td>
<td>性别</td>
</tr>
<%if(user!=null){%>
<tr class="td">
<td><%=user.getId()%></td>
<td><%=user.getUsername()%></td>
<td><%=user.getPassword()%></td>
<td><%=user.getCompany()%></td>
<td><%=user.getAge()%></td>
<td><%=user.getSex()==1?"男":"女"%></td>
</tr>
<%}else{ %>
<tr class="td">
<td style="color: red;">暂无相关数据</td>
</tr>
<%} %>
</table>
</body>
</html>

启动项目，输入localhost:8080/SSM 访问

为方便新手查错，博主按照博文重新搭建了一次，测试无误后将项目打包，上传至云盘，供您使用。（建议：希望您按照博文从头搭建，便于印象深刻）
