在Idea中设置MyBatis核心配置文件的模板

1.先把模板写好

<?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 >
    <!--
       MyBatis核心配置文件中，标签的顺序
       properties - setting - typeAliases - typeHandlers - objectFactory - objectWrapperFactory-
       reflectorFactory - plugins - environments - databaseIdProvider - mappers
    -->
    <properties resource="jdbc.properties" />
    <!--设置类型别名-->
    <typeAliases>
        <package name="" />
    </typeAliases>
    <!--设置连接数据库的环境-->
    <environments default="development">
        <environment id="development">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="${jdbc.dirver}"/>
                <property name="url" value="${jdbc.url}"/>
                <property name="username" value="${jdbc.username}"/>
                <property name="password" value="${jdbc.password}"/>
            </dataSource>
        </environment>
    </environments>
    <!--引入映射文件-->
    <mappers>
        <package name="" />
    </mappers>
</configuration>

加入模板

同上步骤，再创建一个mybatis-mapper接口

<?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=" ">

</mapper>
