将项目由SpringBoot 1.5升级到2.0时要修改数据源配置

SpringBoot 1.5时的数据源配置

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false

升级到SpringBoot 2后,启动出现问题

The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time zone

原因

SpringBoot2.0中使用的jdbc驱动是mysql-connector-java 8,需要指定url的时区serverTimezone。
设置为

jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=UTC

设定serverTimezone=UTC,会比中国时间早8个小时,如果在中国,可以选择Asia/Shanghai或者Asia/Hongkong, 或者GMT+8

## 设置为地区名称
jdbc:mysql://localhost:3306/test&useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=Asia/Shanghai

## 设置GMT+8
jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=GMT%2B8

再次启动,可以运行,但是会有提示

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

这时,只要将驱动由com.mysql.jdbc.Driver改为com.mysql.cj.jdbc.Driver即可。

spring:
  datasource:
    ## 修改这里
    driver-class-name: com.mysql.cj.jdbc.Driver
