一、整合步骤：

新建项目,创建一个lib目录
导入所有的jar包
新建一个config目录，设置为资源目录，用于存放配置文件
把所有需要的配置文件放到config目录中
在web.xml配置加载spring容器
新建所有的类和接口进行测试

二、具体实施

1.新建一个web项目，在web/WEB-INF目录下创建一个lib目录，并把此目录添加到项目依赖

然后点击应用。

2.导入所需要的jar包

3.在根目录下新建一个目录，名为config，并把它设置为资源目录

4.编写所需的配置文件到config目录

1）编写log4j.properties文件（config目录）

### 设置当前日志级别 ###
log4j.rootLogger = debug,stdout,D,E

### 输出信息到控制抬 ###
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n

### 输出DEBUG 级别以上的日志到=E://logs/log.log ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = E://logs/log.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = DEBUG
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n

### 输出ERROR 级别以上的日志到=E://logs/error.log ###
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File =E://logs/error.log 
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR 
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n

2）编写db.properties文件（config目录）

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

3）新建一个mybatis包，编写SqlMapConfig.xml文件

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

4）新建一个spring包，编写applicationContext-dao.xml文件

<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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

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

</beans>

5）编写springmvc.xml文件（spring目录）

<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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx-4.3.xsd ">

    <!--包扫描controller-->
    <context:component-scan base-package="com.ssm.controller"/>

    <!--配置注解处理器映射器和适配器-->
    <mvc:annotation-driven></mvc:annotation-driven>
</beans>

6）编写applicationContext-service.xml文件（spring目录）

<beans xmlns="http://www.springframework.org/schema/beans"

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"/>
</bean>
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>

5.在web.xml配置加载spring容器

<?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"

    <filter>
        <filter-name>charsetEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>CharsetEncoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>

    <filter-mapping>
        <filter-name>charsetEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <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>



    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <!--加载配置文件-->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/springmvc.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
</web-app>

6.新建所有的类和接口

1)UserController

package com.ssm.controller;

import com.ssm.entity.User;
import com.ssm.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@Transactional
public class UserController {
    @Autowired
    private UserService service;
    @RequestMapping("/add.do")
    public String add(User user){
        try{
            service.add(user);
            return "success.html";
        }catch(Exception e){
            e.printStackTrace();
            return "error.html";
        }
    }
}

2）UserService

package com.ssm.service;

import com.ssm.entity.User;

public interface UserService {
    void add(User user);
}

3）UserServiceImpl

package com.ssm.service;

import com.ssm.entity.User;
import com.ssm.mapper.UserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class UserServiceImpl implements UserService{
    @Autowired
    private UserMapper mapper;
    @Override
    public void add(User user) {
        mapper.add(user);
    }
}

4）User

package com.ssm.entity;

import lombok.*;

@Setter
@Getter
@ToString
@AllArgsConstructor
@NoArgsConstructor
public class User {
    private int id;
    private String username;
    private String password;
    private String phone;
}

5）UserMapper

package com.ssm.mapper;

import com.ssm.entity.User;

public interface UserMapper {
    void add(User user);
}

6）UserMapper.xml（与UserMapper同包）

<?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.mapper.UserMapper">
    <insert id="add" parameterType="com.ssm.entity.User">
        insert into user values(1,#{username},#{password},#{phone})
    </insert>
</mapper>

7）index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>用户首页</title>
  </head>
  <body>
  <form action="add.do" method="post">
    <p>用户名：<input type="text" name="username"></p>
    <p>密码：<input type="password" name="password"></p>
    <p>手机号：<input type="text" name="phone"></p>
    <p><input type="submit" value="注册"></p>
  </form>
  </body>
</html>

8）success.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
添加成功
</body>
</html>

9)error.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
添加失败
</body>
</html>

运行测试，当添加成功会跳转到成功界面，添加失败会跳转到失败界面。
