异常

Process finished with exit code 1

原因:自己的粗心大意，jdbcType被我写成了javaType

<resultMap id="BaseResultMap" type="com.atguigu.springcloud.entities.xxxx">
        <id column="id" property="id" javaType="BIGINT"/>
        <id column="serial" property="serial" jdbcType="VARCHAR"/>
    </resultMap>

 

解决办法：JavaType对应的是类里的数据类型，jdbcType对应数据库里的类型

将javaType 改成jdbcType就可以了
