运行时出错

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).

Invalid bound statement (not found): com.miaoshaproject.dao.UserDOMapper.selectByPrimaryKey

    配置文件会不会写错了 mybatis.mapper-locations=classpath:mapping/*.xml

    mybatis-generater.xml中的connectionURL，加参数&nullCatalogMeansCurrent=true：
    然后执行，userDOMapper.xml 里面就会有selectByPrimaryKey
    <!--数据库链接地址账号密码-->
    <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                    connectionURL="jdbc:mysql://localhost:3306/miaosha?useUnicode=true&amp;characterEncoding=utf8&amp;serverTimezone=GMT&amp;nullCatalogMeansCurrent=true"
                    userId="root"
                    password="root">
    </jdbcConnection>
