递归获取包下的class文件

```java(这个居然隐藏不了)

public class TestUrl {


public static void main(String[] args) {
    String pageName = "ogr.test";//包路径
    fileRecursive(pageName);
}



public static  void fileRecursive(String pageName) {
    URL url = Thread.currentThread().getClass().getResource("/" + pageName.replaceAll("\\.", "/"));//把/代替成.
    File file = new File(url.getFile());
    for(File tempFile: file.listFiles()){
        if(tempFile.isDirectory()){
            fileRecursive(pageName+"."+tempFile.getName());
        }else{
            System.out.println(pageName+"."+tempFile.getName());
        }
    }

}

}
