問題：
You must configure either the server or JDBC driver (via the serverTimezone configuration property)
'?й???????' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration
解決方案：
錯誤提示:
Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is JAVA.sql.SQLException: 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.
解決辦法;
在連接字符串后面加上?serverTimezone=UTC
其中UTC是統一標準世界時間。
完整的連接字符串示例：jdbc:MySQL://localhost:3306/test?serverTimezone=UTC
或者還有另一種選擇：jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8，這個是解決中文亂碼輸入問題，當然也可以和上面的一起結合：jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
