控制springboot服务的时区为东八区

@SpringBootApplication
public class Application {
  public static void main(String[] args) {
    // 设置时区为上海时区，即东八区
    TimeZone.setDefault(TimeZone.getTimeZone(ZoneId.SHORT_IDS.get("CTT")));
    SpringApplication.run(Application.class, args);
  }
}

以下是测试例子
springboot 启动时候设置时区，如下代码所示

@SpringBootApplication
public class EwPbServerApplication {

    public static void main(String[] args) {
        TimeZone timeZone = TimeZone.getTimeZone("UTC");
        TimeZone.setDefault(timeZone);
        SpringApplication.run(EwPbServerApplication.class, args);
    }
}

测试请求接口获取时间

	@GetMapping("test")
    @ApiOperation(value = "测试时间", httpMethod = "GET")
    public void test() {
        //当前时间为 2022-09-06 17:46
        //启动类设置时区后，获取当前时间
        Date date = new Date();
        DateTime date1 = DateUtil.date();
        LocalDateTime localDateTime = LocalDateTime.now();
        //设置时区为-东八区
        LocalDateTime.now(ZoneId.of("Asia/Shanghai"))

        log.info("date=={}", date);
        log.info("date1=={}", date1);
        log.info("localDateTime=={}", localDateTime);
        log.info("now=={}", now);
//        2022-09-06 09:47:01.385  xxxx  : date==Tue Sep 06 09:47:01 UTC 2022
//        2022-09-06 09:47:01.385  xxxx  : date1==2022-09-06 09:47:01
//        2022-09-06 09:47:01.386  xxxx  : localDateTime==2022-09-06T09:47:01.381
//        2022-09-06 09:47:01.386  xxxx  : now==2022-09-06T17:47:01.385
    }

由测试结果得知，springboot 启动时设置时区之后全局生效，但是优先级小于手动设置
