闲话不多说，直接上代码吧：
第一：如何更改acegi的源码：在STS 中工程视图改为project explorer ,在工程上点击右击，有个grails tools，里面刷新下依赖，在工程下就应该出现所有插件的源码了，这样就可以改了。
找到了下类：
改为如何下代码：我也记不清怎么改的了：

}
然后再在这外包下面加一个类，其实就是抛出的一个异常类
package org.codehaus.groovy.grails.plugins.springsecurity;
import org.springframework.security.AuthenticationException;
/**
**/
public class ValidationCodeException extends AuthenticationException {
public ValidationCodeException(String s) {
super(s);
}
}
这样就可以了，前台加上代码就行了。
不过，这样还不算玩，如果重做系统之类的，还得改，因为改的代码保存是在C盘。这也让我郁闷啊。这几天换机子，机子坏，改了好几遍了。
记得FCKeditor有上传图片显示不能显示的问题，今天重先发布工程时，网上下载的fckeditor,没改源码也能正常使用了，有点因祸得福的感觉。
