我用的mysql8的数据库，无法连接上去，对应的配置也换成8.0的还是不好使呀

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&amp;characterEncoding=utf8&amp;useSSL=false&amp;serverTimezone=GMT&amp;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
