按文件名、更新时间等查找本地文件夹中文件

文件过滤器，按照文件名称与更新时间过滤

将过滤后的文件按照更新时间排序

            if (diff < 0)
                return 1;

取得文件需要的属性信息

public static List<Map<String, String>> getFileByFilter(FileByCondition fileCondition) {
        String fileDirPath = "D:\tools\Tomcat\Tomcat7\apache-tomcat-7.0.57\logs\urs";
        //获取window或linux下的日志文件目录

        } else {
            fileDirPath = System.getProperty("catalina.home") + "/logs/urs/";
        }*/
        File fileDir = new File(fileDirPath);
        //日志目录下的所有日志文件
        File[] files = fileDir.listFiles(fileCondition);
        //按照修改时间排序   
        Arrays.sort(files, new CompratorByModifiedTime());
        List<Map<String, String>> resultList = new ArrayList<Map<String, String>>();
        for (int i = 0; i < files.length; i++) {
            Map<String, String> fileInfo = new HashMap<String, String>();
            File file = files[i];
            //文件名
            String fileName = file.getName();
            //修改时间
            String modifiedTime = DateUtils.getDateTime(new Date(file.lastModified()));
            //文件大小
            long fileLength = (long) Math.ceil((file.length() / 1024f));
            String fileSize = fileLength + "KB";
            fileInfo.put("fileName", fileName);
            fileInfo.put("fileTime", modifiedTime);
            fileInfo.put("fileSize", fileSize);
            resultList.add(fileInfo);
        }
        return resultList;
    }

main方法测试

public static void main(String[] args) {
        String fileNameCondition = "urs";
        String startTime = "2017-07-11 18:00:58";
        String endTime = "2017-07-29 18:01:00";
        FileByCondition fileCondition = new FileByCondition(fileNameCondition, startTime, endTime);
        List<Map<String, String>> resultList = getFileByFilter(fileCondition);
        System.out.println(resultList.size());
    }
