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
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。
天苍苍,野茫茫,风吹草底见牛羊
