新建一个application.properties配置文件，代码如下：

spring.application.name=spring-boot-config
server.port=8090


#mybatis.config-location=classpath:mybatis-config.xml
#mybatis mapper文件的位置
mybatis.mapper-locations=classpath*:mapping/*.xml
#扫描pojo类的位置,在此处指明扫描实体类的包，在mapper中就可以不用写pojo类的全路径名了
mybatis.type-aliases-package=com.nieyb

jdbc.type=mysql
spring.datasource.name=nieyb
spring.datasource.url=jdbc:mysql://localhost:3306/nybtest
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

还需要建立一个mybatis-generator.xml文件，mybatis-generator.xml文件的目录要与pom文件

<configuration>
    <!--允许移动生成的文件 -->
    <verbose>true</verbose>
    <!-- 是否覆盖 -->
    <overwrite>true</overwrite>
    <!-- 自动生成的配置 -->
    <configurationFile>src/main/resources/mybatis-generator.xml</configurationFile>
</configuration>中的<configurationFile>标签中的目录一致。

代码如下：

        </commentGenerator>
        <!--mysql数据库连接的信息：驱动类、连接地址、用户名、密码 -->
