浏览服务器文件程序片：

/**

       public void kindEditorView(){
    	   HttpServletRequest request = ServletActionContext.getRequest();

    	   //最后一个字符不是/
    	   if (!"".equals(path) && !path.endsWith("/")) {
    	   	out.println("参数无效！");
    	   	return;

    	   result.put("file_list", fileList);
           super.writeJson(result);
       }

浏览服务器文件 用到的三个类：

NameComparator

package zy.comparator;
    
    import java.util.Comparator;
    import java.util.Hashtable;
    
    public class NameComparator implements Comparator {
    	public int compare(Object a, Object b) {
    		Hashtable hashA = (Hashtable) a;
    		Hashtable hashB = (Hashtable) b;
    		if (((Boolean) hashA.get("is_dir")) && !((Boolean) hashB.get("is_dir"))) {
    			return -1;
    		} else if (!((Boolean) hashA.get("is_dir")) && ((Boolean) hashB.get("is_dir"))) {
    			return 1;
    		} else {
    			return ((String) hashA.get("filename")).compareTo((String) hashB.get("filename"));
    		}
    	}
    }

SizeComparator

package zy.comparator;
    
    import java.util.Comparator;
    import java.util.Hashtable;
    
    public class SizeComparator implements Comparator {
    	public int compare(Object a, Object b) {
    		Hashtable hashA = (Hashtable) a;
    		Hashtable hashB = (Hashtable) b;
    		if (((Boolean) hashA.get("is_dir")) && !((Boolean) hashB.get("is_dir"))) {
    			return -1;
    		} else if (!((Boolean) hashA.get("is_dir")) && ((Boolean) hashB.get("is_dir"))) {
    			return 1;
    		} else {
    			if (((Long) hashA.get("filesize")) > ((Long) hashB.get("filesize"))) {
    				return 1;
    			} else if (((Long) hashA.get("filesize")) < ((Long) hashB.get("filesize"))) {
    				return -1;
    			} else {
    				return 0;
    			}
    		}
    	}
    }

TypeComparator

package zy.comparator;
    
    import java.util.Comparator;
    import java.util.Hashtable;
    
    public class TypeComparator implements Comparator {
    	public int compare(Object a, Object b) {
    		Hashtable hashA = (Hashtable) a;
    		Hashtable hashB = (Hashtable) b;
    		if (((Boolean) hashA.get("is_dir")) && !((Boolean) hashB.get("is_dir"))) {
    			return -1;
    		} else if (!((Boolean) hashA.get("is_dir")) && ((Boolean) hashB.get("is_dir"))) {
    			return 1;
    		} else {
    			return ((String) hashA.get("filetype")).compareTo((String) hashB.get("filetype"));
    		}
    	}
    }

说明;

super.writeJson(result);方法是返回JSON；我用的fastjson插件返回json数据

public void writeJson(Object obj){
    		String json = JSON.toJSONStringWithDateFormat(obj, "yyyy-MM-dd HH:mm:ss");
    		ServletActionContext.getResponse().setContentType("text/html;charset=utf-8");
    		try {
    			PrintWriter out = ServletActionContext.getResponse().getWriter();
    			out.write(json);
    			out.flush();
    			out.close();
    		} catch (IOException e) {
    			e.printStackTrace();
    		}
    	}
