1.2 静态资源导出

    <build>
        <resources>
            <resource>
                <directory>src/main/javadirectory>
                <includes>

            resource>
        resources>
    build>

2.配置文件

2.1 db.properties数据库资源配置

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.connectionURL=jdbc:mysql://localhost:3306/mydata?useUnicode=true&characterEncoding=utf-8
jdbc.userId=root
jdbc.password=123456

2.2 mybatis核心文件

mybatis-config.xml

<configuration>

    <typeAliases>
        <package name="com.mvc.pojo"/>
    typeAliases>

    <mappers>
        <mapper class="com.mvc.dao.BooksMapper"/>
