如果路径为null就去读取路径 if path null StringBuffertempPath newStringBuffer tempPath append ReadXML class getResource getPath 获取当前class所在的路径 ReadXML class getResource getPath 你可以用这个方法来获取到你当前class的路径 ReadXML可以替换为你自己当前的class名字 if tempPath length 0 如果路径长度 0则路径存在tempPath deleteCharAt 0 tempPath delete tempPath length 8 tempPath length 删除掉 classes tempPath append fileName path tempPath toString 写的比较久了 那时没有加注释习惯 所以 呵呵 现在勉强加上 你可以使用下看 如果不行 你就用 ReadXML class getResource getPath 这个方法获取到路径 获取到后可能为f aaa WEB INF classes然后删除掉 classes再加上你的XML文件名就行了 后面的没有办法一定要写死的 解析1 xml文件 存放在web info目录下 运用文件目录下

resources resources 专门将文件处理成java文件对象 File InputStream InputStreamReader Properties 和获得该文件的相对路径 相对于classpath 的URL对象 mon resources importjava io importjava util
