MySQL url问题

create connection SQLException, url: jdbc:mysql://localhost:3306/ems_thymeleaf?serverTimezone=CTT&useUnicode=true&characterEncoding=utf-8&useSSL=false, errorCode 0, state 08001

里面的CJ是看网上评论添加上去的

 spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
    spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

报错代码

java.sql.SQLNonTransientConnectionException: Cannot load connection class because of underlying exception: com.mysql.cj.exceptions.WrongArgumentException: Malformed database URL, failed to parse the connection string near ';useUnicode=true&characterEncoding=utf-8&useSSL=false'.

mysql依赖 MySQL版本8.0

<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<scope>runtime</scope>
			<version>8.0.22</version>
		</dependency>

包括这样

url: jdbc:mysql://192.168.56.20:3306/

解决方法去掉
