JAVA读取指定目录的文件夹信息

我这里是读取文件夹中包含指定字符串的html文件

package com.cqjgsoft.util;
import java.io.File;
import java.util.ArrayList;
import java.util.List;

import com.alibaba.fastjson.JSON;

public class GetFoldFileNames {


    public static void main(String[] args) {
        System.out.println(JSON.toJSONString(getFileName()));
    }
    
    /**
     * 获取名字中包含health和.html的数据
     * @author zy
     */
    public static List<String> getFileName() {
        List<String> fileList=new ArrayList<String>();
        String path = PropertisUtil.getApplicationProperties("healthReport.save.urls"); // 路径
        File f = new File(path);
        if (!f.exists()) {
            System.out.println(path + " not exists");
            return new ArrayList<String>();
        }

        File fa[] = f.listFiles();
        for (int i = 0; i < fa.length; i++) {
            File fs = fa[i];
            if (!fs.isDirectory()) {
                //判断是否包含.html
                if(fs.getName().contains(".html")&&fs.getName().contains("health")) {
                    fileList.add(fs.getName());
                }
            }
        }
        //降序(JAVA8特性)
        fileList.sort((a, b) -> b.compareTo(a.toString()));
        return fileList;
    }
}
