请问能出一个mysql8的配置吗，我也报的这个问题，不知道哪的问题了，jdbc.driver都替换了
1、这是我的mybatis-generator.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <generatorConfiguration> <context id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <property name="suppressDate" value="true"/> <property name="suppressAllComments" value="true"/> </commentGenerator> <!--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&characterEncoding=utf8&useSSL=false&serverTimezone=GMT&nullCatalogMeansCurrent=true" userId="root" password="123456"> </jdbcConnection> <javaTypeResolver> <property name="forceBigDecimals" value="false"/> </javaTypeResolver> <!--生成DataObject类存放位置--> <javaModelGenerator targetPackage="com.miaoshaoproject.dataobject" targetProject="src/main/java"> <property name="enableSubPackages" value="true" /> <property name="trimStrings" value="true" /> </javaModelGenerator> <!--生成映射文件存放位置 --> <sqlMapGenerator targetPackage="mapping" targetProject="src/main/resources"> <property name="enableSubPackages" value="true" /> </sqlMapGenerator> <!--生成DAO类型的文件--> <javaClientGenerator targetPackage="com.miaoshaoproject.dao" targetProject="src/main/java" type="XMLMAPPER"> <property name="enableSubPackages" value="false" /> </javaClientGenerator> <!--生成对应表及类名--> <!--<table tableName="user_info" domainObjectName="UserDO" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>--> <table tableName="user_info" domainObjectName="UserDO"></table> <table tableName="user_password" domainObjectName="UserPasswordDO"></table> </context> </generatorConfiguration>
2、这是我的pom.xml
