1.引入项目依赖的jar包（pop.xml）

包含：spring、springmvc、mybatics、Mybatis整和Spring的适配包、数据库连接池、mysql驱动、单元测试

(注意版本问题！！！)

</project>

    此处一定要注意版本，以及依赖jar包的问题，不然很容易出问题（比如c3p0，除了导入c3p0的jar包外，还要导入一个依赖jar包！！！！！）

2.配置mybatis（mybatis-config.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>
   <settings>
      <setting name="mapUnderscoreToCamelCase" value="true"/>
   </settings>
  
   <typeAliases>
      <package name="com.atguigu.crud.bean"/>
   </typeAliases>
 
</configuration>

3.配置spring

3.1配置dao（applicationContext-dao.xml）

   <!-- 配置一个可以执行批量的sqlSession -->
   <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
      <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"></constructor-arg>
      <constructor-arg name="executorType" value="BATCH"></constructor-arg>
   </bean>
   <!--=============================================  -->
</beans>

数据库配置文件（dbconfig.properties）

jdbc.jdbcUrl=jdbc:mysql://localhost:3306/ssm_crud?useUnicode=true&characterEncoding=UTF-8&useSSL=false
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=root
jdbc.password=1022zhang

3.2配置service（applicationContext-service.xml）

   <!-- 除了Controler层都扫描 -->
   <context:component-scan base-package="com.atguigu">
      <context:exclude-filter type="annotation"
         expression="org.springframework.stereotype.Controller" />

      </tx:attributes>
   </tx:advice>
  
   <!-- Spring配置文件的核心点（数据源、与mybatis的整合，事务控制） -->
