使用druid报错:Could not create connection to database server. Attempted reconnect 3 times. Giving up.

由 心不动则不痛 提交于 2020-01-09 16:42:01
错误原因分析： 1.数据库版本过低，比如使用mysql5.0，jdbc驱动使用了8.0.12 此处解决办法：更换高版本mysql比如mysql8（亲测有效）,要么将jdbc驱动换回5.1.28，但更换低版本驱动可能会导致不可测的新问题，抛出新的异常 2.时区问题 此处解决办法：在jdbc连接的url后面加上serverTimezone=GMT即可解决问题，如果需要使用gmt+8时区，需要写成GMT%2B8，否则会被解析为空。 ----end-------- 来源： CSDN 作者： KogRow 链接： https://blog.csdn.net/shuaicenglou3032/article/details/103889086

How to handle Day Light Saving in Oracle database

问题 In one of the Oracle database server it is showing "+01:00" when I fire the "Select dbtimezone from dual" does that mean in summer the clock will shift one hour ahead ?. In another server it is showing "+00:00" does that mean the database server setting is GMT ? but I am using the sysdate in oracle pl/sql. Client is saying the Aix server is on DST so would that mean the DB server will adopt the AIX server setting after clock change ? How to fix this problem. 回答1: Answer is: It depends. In

1.springboot框架返回前端时间格式不正确： 1540907384711或者"2020-0118T13:01:01.000+0000" 原因：spring-boot中对于@RestController或者@Controller+@ResponseBody注解的接口方法的返回值默认是使用jacksonjar包的json格式。 解决办法： 配置文件上加入 ： spring.jackson.date-format=yyyy-MM-dd spring.jackson.time-zone=GMT+8 或者：在需要的字段上加入 @JsonFormat (pattern= "yyyy年MM月dd日 HH时mm分ss秒" ,timezone = "GMT+8" ) 来源： https://www.cnblogs.com/TanShan/p/12148857.html

Converting GMT time to local time using timezone offset, not timezone identifier

由 不羁岁月 提交于 2020-01-06 07:57:13
问题 It's pretty easy to convert a given GMT date into local time if you're given the timezone identifier from this list in PHP: http://www.php.net/manual/en/timezones.php For example, you can do this (where $fromTimeZone is just 'GMT', $toTimeZone is just one of the constants from that list (i.e. 'America/Chicago'), and $datetime is the GMT date): public static function convertToTimezone($datetime, $fromTimeZone, $toTimeZone, $format = 'Y-m-d H:i') { // Construct a new DateTime object from the

使用SpringBoot连接mysql的时候报错了 通过报错信息看到是时区的问题，原因是没有在application.properties设置好 application.properties mysql的配置修改 serverTimezone=GMT%2B8 （格林尼治标准时间，曾是世界时） 也可以设置成其它时区如UTC（协调世界时，现作为世界标准时间使用） 来源： CSDN 作者： TonyPaPa 链接： https://blog.csdn.net/weixin_40208575/article/details/103800183

Java time in GMT

由 你说的曾经没有我的故事 提交于 2020-01-01 11:45:27
问题 I have a Grails application with the following code: Date now = Calendar.getInstance().getTime() //Also tried new Date() println "now: " + now When I do this, I get now: Thu Aug 18 12:47:09 CDT 2011 . I need the date to be in GMT, not local time because I need to store the GMT time in a database. I can use a simpleDateFormat object to print out the time in GMT, but I need to actually store it as GMT. Question: How do I convert a Date object to a Date object using GMT? 回答1: This accentuates

How to convert datetime to GMT in php

由 限于喜欢 提交于 2020-01-01 07:22:24
问题 Alright, so i'm not sure if im converting user input time to GMT properly. I will be having users across several timezones entering "events" and they will have to be able to see "how long untill" or "how long since" the current time(); This is how I was planning to convert the time they input. It will start as something like 07/21/2011 01:30 am Then, echo gmdate('Y-m-d H:i:s',strtotime('07/21/2011 01:30 am')); gives me 2011-07-21 08:30:00 So I was planning to take the value of gmdate('Y-m-d H

（一招搞定）tomcat与服务器时间相差8小时，修改catalina.sh后还不行怎么办？

由 人盡茶涼 提交于 2019-12-30 16:25:04
在网上查询尝试了一些办法如：修改tomcat文件下的bin/catalina 文件中set JAVA_OPTS= -Duser.timezone=GMT+08 仍然不行↑↑↑ 后来查到有些特殊情况下是不允许修改代码的, 如没有编译环境,代码闭源等 。 这个时候我们就要 从JVM入手了 ,一个tomcat进程对应一个JVM,我们可以对这个JVM设置一些启动参数，带着这个疑问我们找到了解决方法 修改tomcat/bin/setclasspath.sh（windows下修改.bat）文件 #windows下编辑tomcat/bin/setclasspath.bat(在所有代码之前添加) set JAVA_OPTS="-Duser.timezone=GMT" #linux编辑tomcat/bin/setclasspath.sh（在所有代码之前添加） export JAVA_OPTS="-Duser.timezone=GMT" #如果设置了随机启动脚本要修改随机启动脚本，请修改 vim /etc/init.d/tomcat export JAVA_OPTS="-Duser.timezone=GMT+8:00" 或 export JAVA_OPTS="-Duser.timezone=GMT+8" 来源： CSDN 作者： _陈哈哈 链接： https://blog.csdn.net/qq
