Eclipse 修改注释的 date time 日期时间格式，即${date}变量格式

Eclipse 修改注释的 date time 日期时间格式，即${date}变量格式

找到eclipse安装目录下面的plugins目录，搜索 org.eclipse.text ，找到一个jar包，

例如我找到的jar包为：org.eclipse.text_3.5.300.v20130515-1451.jar

然后打开它，找到这个类： org.eclipse.jface.text.templates.GlobalTemplateVariables

我们重写这个类就行了。（可反编译，也可以找到源码，源码下载地址为：http://git.eclipse.org/c/platform/eclipse.platform.text.git，下载zip包） PS：如果嫌下载源码包麻烦，我这里贴出这个文件的源码，可以直接用（注：这个类很简单，无多少依赖，所有版本通用，无需担心jar包的版本问题）

我改成了使用

import java.text.SimpleDateFormat;

import java.util.Calendar;

并且从properties文件中读取format格式，可以借鉴。

我提供编译好的class文件供大家下载（下载下面的图片，把jpg后缀 改成rar后缀，然后打开），替换到原文件即可。

Eclipse 修改注释的 date time 日期时间格式，即${date}变量格式的相关文章

Linux之简单命令之日期时间命令之date，cal，clock ,hwclock和tzselect

一.date命令: 在linux环境中,不管是编程还是其他维护,时间是必不可少的,也经常会用到时间的运算,熟练运用date命令来表示自己想要表示的时间,肯定可以给自己的工作带来诸多方便. 1．命令格式: date [参数]... [+格式] 2．命令功能: date 可以用来显示或设定系统的日期与时间. 3．命令参数: 必要参数: %H 小时(以00-23来表示).  %I 小时(以01-12来表示).  %K 小时(以0-23来表示).  %l 小时(以0-12来表示).  %M 分钟(以00

数据库日期时间显示在页面上格式错误的解决方案

做项目过程中肯定会碰到这样一个问题:在数据库中存的是date或datetime类型的值,从数据库里取出来遍历到页面上显示的是long类型或是GTM类型的日期时间.对于这个问题,经过研究之后有以下结论: 1.hibernate不会出现这样的问题,而mabatis则会出现这个问题. 2.数据库使用date类型的在页面上会显示long类型日期时间,使用datetime类型的在页面上会显示GTM类型日期时间. 因为我用的是mysql数据库,其他的数据库没测试过,所以也不知道其他数据库是怎样的情况,这里就

c/c++日期时间处理与字符串string转换

在c/c++实际问题的编程中,我们经常会用到日期与时间的格式,在算法运行中,通常将时间转化为int来进行计算,而处理输入输出的时候,日期时间的格式却是五花八门,以各种标点空格相连或者不加标点. 首先,在c中,是有一个标准的日期时间结构体的,在标准库wchar.h内,我们可以看到结构体tm的声明如下: 1 #ifndef _TM_DEFINED 2 struct tm { 3 int tm_sec; /* seconds after the minute - [0,59] */ 4 int tm_

Java常用类库之时间操作类——Date、Calendar、DateFormat、SimpleDateFormat及实例操作

学习目标 掌握Date类的使用 可以使用Calendar类取得一个完整的日期 掌握日期格式化的操作 可以使用SimpleDateFormat进行日期的格式化转换操作 编写取得日期的操作类 进一步掌握Calendar类的使用 进一步掌握SimpleDateFormat类的使用 Date类是一个较为常用的类,但是其操作的日期格式会有一些不符合个人要求,而如果想要进一步取得一些自己需要的时间,则可以使用Calendar类. Date类 在java.util包中定义了Date类,Date类本身使用非常简
