Solve the problem

mapper.xml generated duplicate codes

Solution: xml configuration, remove the code below

<property name="suppressAllComments" value="true"/>

Unable to generate selectByPrimaryKey, deleteByPrimaryKey methods

The mysql-driven version reduced to 5.x, has not been verified

or

Add the following tag (effective, recommended)

<jdbcConnection driverClass="com.mysql.cj.jdbc.Driver" connectionURL="" userId="" password="">
    <property name="useInformationSchema" value="true"/>
</jdbcConnection>
