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

protected String resolve(TemplateContext context) ...{
        // return DateFormat.getDateInstance().format(new java.util.Date());
        // Modified by [e-mail]
        final SimpleDateFormat df = new SimpleDateFormat("yyyy/MM/dd");
        return df.format(new java.util.Date());
    }

 

 时间格式修改为：

java 代码

/**
 * {@inheritDoc}
 */
protected String resolve(TemplateContext context) ...{
    // return DateFormat.getTimeInstance().format(new java.util.Date());
    // Modified by [e-mail]
    final SimpleDateFormat ldf = new SimpleDateFormat("HH:mm:ss");
    return ldf.format(new java.util.Date());
}

 

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

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

 

类注释模板：

java 代码

/**
 * Class ${type_name}
 *
 * @author
 * @version $$Revision:1.0.0, $$Date: ${date} ${time} $$
 * ${tags}
 */

 

以下是新生成的Test类：

java 代码

/**
 * @(#)Test.java 1.0.0 2007/05/10 14:10:11
 *
 * Copyright 2007 Cepiao Co. Ltd.  All rights reserved.
 * CEPIAO PROPRIETARY/CONFIDENTIAL. Use is subject to license terms.
 */
package com.cepiao.test;

/**
 * Class Test
 *
 * @author
 * @version $Revision:1.0.0, $Date: 2007/05/10 14:10:11 $
 */
public class Test {

}

 

发下是修改过的GlobalTemplateVariables类源代码：
