修改Eclipse的Date变量格式

??? 自从Eclipse升级到3.2版本以后，其代码模板的当前日期变量{$Date}的格式就不再符合国人习惯。在3.2版本中，日期格式为“2007-5-10 上午06:58:10”格式；在3.3版本中，日期格式则为“2007 五月 10 17:20:02”格式。我还是习惯采用“yyyy/MM/dd HH:mm:ss”格式，但无论怎么修改Windows系统的区域设置，Eclipse的Date格式还是没有变化。

Eclipse 的Date变量在GlobalTemplateVariables类中定义，如果要修改日期格式，则需要修改GlobalTemplateVariables类。这个类在Eclipse插件目录org.eclipse.text_3.3.0.v20070503-0800.jar(3.3.0 M7版本)文件的org.eclipse.jface.text.templates包中，我的办法是：

1、在eclipse的源代码中修改org.eclipse.text项目的GlobalTemplateVariables类。

日期格式修改为：

java 代码?

1. protected?String?resolve(TemplateContext?context)?...{??
2. ????????//?return?DateFormat.getDateInstance().format(new?java.util.Date());??
3. ????????//?Modified?by?yawolf@gmail.com??
4. ????????final?SimpleDateFormat?df?=?new?SimpleDateFormat("yyyy/MM/dd");??
5. ????????return?df.format(new?java.util.Date());??
6. ????}??

?

?时间格式修改为：

java 代码?

1. /**
   
2. ?*?{@inheritDoc}?
3. ?*/??
4. protected?String?resolve(TemplateContext?context)?...{??
5. ????//?return?DateFormat.getTimeInstance().format(new?java.util.Date());??
6. ????//?Modified?by?yawolf@gmail.com??
7. ????final?SimpleDateFormat?ldf?=?new?SimpleDateFormat("HH:mm:ss");??
8. ????return?ldf.format(new?java.util.Date());??
9. }??

?

2、将修改过的类编译，然后再打包成org.eclipse.text_3.3.0.v20070503-0800.jar文件，并放进Eclipse插件目录。

3、重启Eclipse系统，即可使用新的&{Date}及%{Time}格式。

以下是我的文件头注释模板：

java 代码?

1. /**
2. ?*?@(#)${file_name}?1.0.0?${date}?${time}?
3. ?*?
4. ?*?Copyright?${year}?Cepiao?Co.?Ltd.??All?rights?reserved.?
5. ?*?CEPIAO?PROPRIETARY/CONFIDENTIAL.?Use?is?subject?to?license?terms.?
6. ?*/??

?

类注释模板：

java 代码?

1. /**??
2. ?*?Class?${type_name}?
3. ?*?
4. ?*?@author??
5. ?*?@version?$$Revision:1.0.0,?$$Date:?${date}?${time}?$$?
6. ?*?${tags}?
7. ?*/??

?

以下是新生成的Test类：

java 代码?

1. /**?
2. ?*?@(#)Test.java?1.0.0?2007/05/10?14:10:11?
3. ?*?
4. ?*?Copyright?2007?Cepiao?Co.?Ltd.??All?rights?reserved.?
5. ?*?CEPIAO?PROPRIETARY/CONFIDENTIAL.?Use?is?subject?to?license?terms.?
6. ?*/??
7. package?com.cepiao.test;??
8. ??
9. /**?
10. ?*?Class?Test?
11. ?*?
12. ?*?@author??
13. ?*?@version?$Revision:1.0.0,?$Date:?2007/05/10?14:10:11?$?
14. ?*/??
15. public?class?Test?{??
16. ??
17. }??

?
