			<directory>src/main/java</directory>
      <includes>
          <include>**/*.properties</include>
          <include>**/*.xml</include>
			</includes>
		<filtering>true</filtering>
	</resource>
</resources>
</build>

Spring5整合Mybatis

​ 1,编写Spring配置文件applicationContext.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"
      xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
  <!--配置数据源：数据源有非常多，可以使用第三方的，也可使使用Spring的
		配置数据源替换mybatis的数据源		
-->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
   <!-- 配置连接池属性 -->
         <property name="driverClass" value="com.mysql.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssmbuild?useSSL=false&amp;useUnicode=true&amp;serverTimezone=UTC&amp;characterEncoding=UTF-8"/>
        <property name="user" value="root"/>
        <property name="password" value="123456"/>
</bean>

2，配置SqlSessionFactory,关联MyBatis

<!--sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!--注入数据源 dataSource-->
        <property name="dataSource" ref="dataSource" />

        <!--绑定Mabatis配置文件,就是要告诉Mybatis去哪里找对应的sql语句-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
        <property name="mapperLocations" value="classpath:com/yp/dao/*.xml"/>

    </bean>

3,注册SqlSession

 <!-- 3.配置扫描Dao接口包，动态实现Dao接口注入到spring容器中 -->
    <!--解释 ： https://www.cnblogs.com/jpfss/p/7799806.html-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

        <!-- 注入sqlSessionFactory -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>

        <!--给出需要扫描Dao接口包,完成Bean的注入，动态实现Dao接口注入到Spring容器中 -->
        <property name="basePackage" value="com.yp.dao"/>
    </bean>
