mapper generator自動生成所有庫下的所有表怎麼辦？

解決方法:

<jdbcConnection driverClass="com.mysql.cj.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1:3306/myshop?useSSL=false&amp;serverTimezone=UTC" userId="root" password="1234">
            <property name="nullCatalogMeansCurrent" value="true"/>
 </jdbcConnection>

在配置文件generatorConfig.xml中加入<property name="nullCatalogMeansCurrent" value="true"/>
配置文件generatorConfig.xml
