eclipse中的Java文件自动根据svn版本号生成注释

经常在java代码中看到以下的注释（$Rev: $Date）,是不是很酷,怎么生成的呢？

/**
 * A FilterChain is an object provided by the servlet container to the developer
 * giving a view into the invocation chain of a filtered request for a resource. Filters
 * use the FilterChain to invoke the next filter in the chain, or if the calling filter
 * is the last filter in the chain, to invoke the rosource at the end of the chain.
 *
 * @see Filter
 * @since Servlet 2.3
 *
 * @version $Rev: 46019 $ $Date: 2004-09-14 04:56:06 -0500 (Tue, 14 Sep 2004) $
 */
public interface FilterChain {

一、eclipse中配置：

windows-->preference
Java-->Code Style-->Code Templates
code-->new Java files
编辑它

* 更新: $$Date$$

* 作者: $$Author$$

* 版本: $$Rev$$

* ID ：$$Id$$

二、修改svb配置文件

windows7 下 ，修改 C:/Users/your username/AppData/Roaming/Subversion 目录下

xp下，修改C:/Documents and Settings/Administrator/Application Data/Subversion/ 目录下

的 config文件，取消掉 “enable-auto-props = yes” 的注释

在[auto-props]下，加入：

*.java = svn:keywords=Date Rev Id Author

*.txt = svn:keywords=LastChangedDate LastChangedRevision
