本文详细介绍如何使用Spring、SpringMVC及MyBatis（简称SSM）进行项目整合，包括搭建开发环境、配置核心文件、实现数据库交互等功能，并通过具体案例验证了整合效果。

第一步：创建maven项目
1.1 打开idea，选择创建项目：Create New Project
这里写图片描述

1.2 在打开的对话框中选中maven，配置jdk、maven home，选择web app骨架等。
这里写图片描述

1.3 填写项目的 g、a、v 即：包名、模块名、版本号。
这里写图片描述

1.4 为了加快maven的构建，添加本地的catelog=local

这里写图片描述

1.5 填写项目的名称

这里写图片描述

1.6 在新建的maven项目中，修改web.xml信息改为最新的版本

这里写图片描述

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                      http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0"
         metadata-complete="true">

第二步：配置pom.xml文件，导入依赖的jar包。

<dependencies>
    <!--配置依赖 -->
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.10</version>

  </dependencies>

第三步：ssm框架的整合。
版本号:
mybatis :3.2.8
spring:4.2.X

3.1 配置mybatis的核心配置文件。

在src/main/resource/
创建mybatis文件夹，创建mybatis-config.xml配置文件
这里写图片描述

内容如下：

<?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>
    <!--配置mybatis的一些设置 -->
    <settings>
        <!--支持主键自增 -->
        <setting name="useGeneratedKeys" value="true"/>
        <!--支持驼峰转换 -->
        <setting name="mapUnderscoreToCamelCase" value="true"/>
        <!-- 设置列明自定义-->
        <setting name="useColumnLabel" value="true"/>
    </settings>
    <!-- 类型映射-->
    <typeAliases>
        <package name="com.jlju.docmanager.bean"/>
    </typeAliases>

</configuration>

3.2 配置数据库连接信息：jdbc.properties

driverClass=com.mysql.jdbc.Driver
jdbcUrl=jdbc:mysql://localhost:3306/docmanager?useUnicode=true&characterEncoding=utf8
user=root
password=x5

3.3 spring 与mybatis整合：spring-jdbc.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: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 http://www.springframework.org/schema/context/spring-context.xsd">
       <!-- 加载jdbc配置文件-->
       <context:property-placeholder location="classpath:jdbc.properties"/>
       <!-- 配置数据源-->
       <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
               <!--数据库连接属性 -->
              <property name="driverClass" value="${driverClass}"/>
              <property name="jdbcUrl" value="${jdbcUrl}"/>
              <property name="user" value="${user}"/>
              <property name="password" value="${password}"/>

              <!-- 数据源连接配置-->
              <property name="autoCommitOnClose" value="false"/>
              <property name="checkoutTimeout" value="3000"/>
              <property name="acquireRetryAttempts" value="3"/>
              <property name="maxPoolSize" value="5"/>
              <property name="minPoolSize" value="3"/>
       </bean>

       <!--配置mybatis -->
       <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
              <!-- 配置数据源-->
              <property name="dataSource" ref="dataSource"/>
              <!--配置属性文件位置 -->
              <property name="configLocation" value="classpath:mybatis/mybatis-config.xml"/>
              <!-- 配置mapper文件位置-->
              <property name="mapperLocations" value="classpath:mybatis/mapper/*.xml"/>
       </bean>

       <!-- 配置dao接口自动生成-->

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

3.3 事务配置 spring-tx.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:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
       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/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
       <!-- 配置事务-->
       <!-- 配置包扫描-->
       <context:component-scan base-package="com.jlju.docmanager.service.impl"/>

       <!--配置事务管理器 -->
       <bean id="transactionManager"  class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
              <!-- 配置要引用的datasource-->
              <property name="dataSource" ref="dataSource"/>
       </bean>
        <!--启动注解式事务管理器 -->
       <tx:annotation-driven transaction-manager="transactionManager"/>
</beans>

3.4 spring mvc配置:srping-mvc.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:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       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/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!-- 配置mvc-->
    <!-- 配置注解-->
    <mvc:annotation-driven/>
    <!--配置包扫描 -->
    <context:component-scan base-package="com.jlju.docmanager.controller"/>


    <!-- 配置视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!--配置静态资源解析器 -->
    <mvc:default-servlet-handler/>
</beans>

3.5 spring-mvc 前端控制器配置：web.xml中添加配置

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                      http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0"
         metadata-complete="true">


  <display-name>DocManager</display-name>
  <!-- 配置servlet 前端控制器-->

    <servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/spring-*.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

3.6 事务测试

 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(value = {"classpath:spring/spring-dao.xml","classpath:spring/spring-tx.xml"})
public class UsersSerivceTest {

    @Autowired
    private UsersSerivce us;
    @Test
    public void testQueryAllUsers() throws Exception {

        List<Users> userses = us.queryAllUsers();
        System.out.println(userses.size());
    }

    @Test
    public void testInsertUsers() throws Exception {
        Users u = new Users();
        u.setPassword("123");
        u.setRealName("丁春秋");
        u.setUsername("1235");
         us.insertUsers(u);
        System.out.println();

    }
}
