Please select one of the following time zone regions.

3) central China - Sichuan, Yunnan, Guangxi, Shaanxi, Guizhou, etc.
4) most of Tibet & Xinjiang
5) west Tibet & Xinjiang
#? 1

The following information has been given:

    China
    east China - Beijing, Guangdong, Shanghai, etc.

Therefore TZ='Asia/Shanghai' will be used.
Local time is now:  Fri Jan 25 15:10:18 CST 2019.
Universal Time is now:  Fri Jan 25 07:10:18 UTC 2019.
Is the above information OK?
1) Yes
2) No
#? 1

You can make this change permanent for yourself by Appending the line
    TZ='Asia/Shanghai'; export TZ
to the file '.profile' in your home directory; then log out and log in again.

Here is that TZ value again, this time on standard output so that you
can use the /usr/bin/tzselect command in shell scripts:
Asia/Shanghai
[root@engine ~]#

調整時區文件到對應目錄

備份當前的時區配置

[root@engine ~]# mv /etc/localtime /etc/localtime-old

替換系統時區文件

[root@engine ~]# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

或者創建鏈接文件

[root@engine ~]# ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

修改clock系統配置文件/etc/sysconfig/clock為如下內容

[root@swk-204 ~]# cat /etc/sysconfig/clock
ZONE="Asia/Shanghai"
UTC=false                          #設置為false，硬件時鐘不于utc時間一致
ARC=false
[root@swk-204 ~]#

設置操作系統環境變量TZ

在/etc/profile或~/.bashrc文件中設置環境變量TZ

export TZ='Asia/Shanghai'

或者

TZ='Asia/Shanghai'; export TZ

通過source命令即可完成設置

JAVA進程調整時區

AVA硬編碼

import java.util.TimeZone;
import javax.annotation.PostConstruct;
import org.springframework.stereotype.Component;

@Component
public class TimeZoneStartup {  
    /**
     * 設置時區
     */
    @PostConstruct
    public void init(){
        TimeZone.setDefault(TimeZone.getTimeZone("Asia/Shanghai"));
    }
    
}

按照以上方法操作后，可以獲取指定的時區
