Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone value '?й???????' 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.

2、解决方式

  • mysql连接的db.url.0后面追加配置：&serverTimezone=Asia/Shanghai
db.url.0=jdbc:mysql://localhost:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&serverTimezone=Asia/Shanghai
  • 再次启动，报错消失
