jmeter连接mysql数据库出错Cannot create PoolableConnectionFactory

用jmeter进行数据库压测是时候出现了如下错误

Cannot create PoolableConnectionFactory (The server time zone value ‘???��������??��??’ is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.)
可以看出是时区的错误
那么尝试添加时区在JDBC Connection Configuration配置中的Database URL添加
?serverTimezone=UTC
在运行

果然成功了
