应用没有使用到DataSource，但是在pom.xml里引入了mybatis-spring-boot-starter

问题解决办法
有两种：
把mybatis-spring-boot-starter的依赖去掉，这样就不会触发spring boot相关的代码
把spring boot自动初始化DataSource相关的代码禁止掉

禁止的办法有两种：

在启动类的@SpringBootApplication加上

    @SpringBootApplication(exclude = { DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class })

在application.properties里配置：

    spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration,org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration
