Spring Boot连接MySQL报错“Internal Server Error”的解决办法

报错信息如下：

{timestamp: "2018-06-14T03:48:23.436+0000", status: 500, error: "Internal Server Error",…}
error
:
"Internal Server Error"
message
:
"Could not open JDBC Connection for transaction; nested exception is java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' 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."

这个问题我之前在ubuntu上没有遇到，是在Windows上使用时出现了这个问题。

解决办法：

在spring.datasource.url对应的URL后面加?serverTimezone=UTC&useUnicode=true&characterEncoding=UTF-8

例：

spring.datasource.url=jdbc:mysql://localhost:3306/zifeiydb?serverTimezone=UTC&useUnicode=true&characterEncoding=UTF-8

完整的一个application.properties例子：

# DB Configuration
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/zifeiydb?serverTimezone=UTC&useUnicode=true&characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=password
# logging
