如何解决springboot数据库查询时出现的时区差异问题

&serverTimezone=GMT%2b8

 primary:
      jdbc-url: jdbc:mysql://******:3306/***?useUnicode=true&characterEncoding=UTF8&zeroDateTimeBehavior=convertToNull&serverTimezone=GMT%2b8
      username: ****
      password: *****
    secondary:
      jdbc-url: jdbc:mysql://*******:3306/***?useUnicode=true&characterEncoding=UTF8&zeroDateTimeBehavior=convertToNull&serverTimezone=GMT%2b8
      username: *****
      password: ********

&serverTimezone=GMT+8 这里使用%2b替换 + 号

#在application.yml中增加配置
spring:
    jackson:
        time-zone: GMT+8

Calendar calendar = Calendar.getInstance();      
        System.out.println("目前时间：" + calendar.getTime());
        System.out.println("Calendar时区：：" + calendar.getTimeZone().getID());
        System.out.println("user.timezone：" + System.getProperty("user.timezone"));
        System.out.println("user.country：" + System.getProperty("user.country"));
        System.out.println("默认时区：" + TimeZone.getDefault().getID());

spring.jackson.date-format: yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone: GMT+8

@JsonFormat(timezone = “GMT+8”, pattern = “yyyy-MM-dd HH:mm:ss”)
