手机号码格式验证和 FASTDFS 工具类

• 常见大陆和香港号码格式验证

  import java.util.regex.Matcher;
  import java.util.regex.Pattern;
  import java.util.regex.PatternSyntaxException;
  
  public class PhoneFormatCheckUtils {
  
      // 大陆号码或香港号码均可
      public static boolean isPhoneLegal(String str) throws PatternSyntaxException {
          return isChinaPhoneLegal(str) || isHKPhoneLegal(str);
      }
  
      /**
       * 大陆手机号码11位数，匹配格式：前三位固定格式+后8位任意数
       * 此方法中前三位格式有：
       * 13+任意数
       * 15+除4的任意数
       * 18+除1和4的任意数
       * 17+除9的任意数
       * 147
       */
      public static boolean isChinaPhoneLegal(String str) throws PatternSyntaxException {
          String regExp = "^((13[0-9])|(15[^4])|(18[0,2,3,5-9])|(17[0-8])|(147))\\d{8}$";
          Pattern p = Pattern.compile(regExp);
          Matcher m = p.matcher(str);
          return m.matches();
      }
  
      /**
       * 香港手机号码8位数，5|6|8|9开头+7位任意数
       */
      public static boolean isHKPhoneLegal(String str) throws PatternSyntaxException {
          String regExp = "^(5|6|8|9)\\d{7}$";
          Pattern p = Pattern.compile(regExp);
          Matcher m = p.matcher(str);
          return m.matches();
      }
  }

• 对 FASTDFS 的封装以及使用

  import org.csource.common.NameValuePair;
  import org.csource.fastdfs.*;
  
  public class FastDFSClient {
  
      private TrackerClient trackerClient = null;
      private TrackerServer trackerServer = null;
      private StorageServer storageServer = null;
      private StorageClient1 storageClient = null;
  
      public FastDFSClient(String conf) throws Exception {
          if (conf.contains("classpath:")) {
              conf = conf.replace("classpath:", this.getClass().getResource("/").getPath());
          }
          ClientGlobal.init(conf);
          trackerClient = new TrackerClient();
          trackerServer = trackerClient.getConnection();
          storageServer = null;
          storageClient = new StorageClient1(trackerServer, storageServer);
      }
  
      /**
       * 上传文件方法
       * <p>Title: uploadFile</p>
       * <p>Description: </p>
       *
       * @param fileName 文件全路径
       * @param extName  文件扩展名，不包含（.）
       * @param metas    文件扩展信息
       * @return
       * @throws Exception
       */
      public String uploadFile(String fileName, String extName, NameValuePair[] metas) throws Exception {
          String result = storageClient.upload_file1(fileName, extName, metas);
          return result;
      }
  
      public String uploadFile(String fileName) throws Exception {
          return uploadFile(fileName, null, null);
      }
  
      public String uploadFile(String fileName, String extName) throws Exception {
          return uploadFile(fileName, extName, null);
      }
  
      /**
       * 上传文件方法
       * <p>Title: uploadFile</p>
       * <p>Description: </p>
       *
       * @param fileContent 文件的内容，字节数组
       * @param extName     文件扩展名
       * @param metas       文件扩展信息
       * @return
       * @throws Exception
       */
      public String uploadFile(byte[] fileContent, String extName, NameValuePair[] metas) throws Exception {
  
          String result = storageClient.upload_file1(fileContent, extName, metas);
          return result;
      }
  
      public String uploadFile(byte[] fileContent) throws Exception {
          return uploadFile(fileContent, null, null);
      }
  
      public String uploadFile(byte[] fileContent, String extName) throws Exception {
          return uploadFile(fileContent, extName, null);
      }
  }
  

  如何使用 FASTDFS? 封装类

  resources 下配置 FASTDFS 信息：fdfs_client.conf 和 application.properties

  # connect timeout in seconds
  # default value is 30s
  connect_timeout=30
  
  # network timeout in seconds
  # default value is 30s
  network_timeout=60
  
  # the base path to store log files
  base_path=/home/fastdfs
  
  # tracker_server can ocur more than once, and tracker_server format is
  #  "host:port", host can be hostname or ip address
  tracker_server=192.168.25.133:22122
  
  #standard log level as syslog, case insensitive, value list:
  ### emerg for emergency
  ### alert
  ### crit for critical
  ### error
  ### warn for warning
  ### notice
  ### info
  ### debug
  log_level=info
  
  # if use connection pool
  # default value is false
  # since V4.05
  use_connection_pool = false
  
  # connections whose the idle time exceeds this time will be closed
  # unit: second
  # default value is 3600
  # since V4.05
  connection_pool_max_idle_time = 3600
  
  # if load FastDFS parameters from tracker server
  # since V4.05
  # default value is false
  load_fdfs_parameters_from_tracker=false
  
  # if use storage ID instead of IP address
  # same as tracker.conf
  # valid only when load_fdfs_parameters_from_tracker is false
  # default value is false
  # since V4.05
  use_storage_id = false
  
  # specify storage ids filename, can use relative or absolute path
  # same as tracker.conf
  # valid only when load_fdfs_parameters_from_tracker is false
  # since V4.05
  storage_ids_filename = storage_ids.conf
  
  #HTTP settings
  http.tracker_server_port=80
  
  #use "#include" directive to include HTTP other settiongs
  ##include http.conf
  
  =====================================================================================
  
  FILE_SERVER_URL=http://192.168.25.133/

  代码演示

  @RestController
  public class UploadController {
  
      @Value("${FILE_SERVER_URL}")
      private String FILE_SERVER_URL; //文件服务器地址
  
      @RequestMapping("/upload")
      public Result upload(MultipartFile file) {
  
          // 获取文件扩展名称
          String originalFilename = file.getOriginalFilename();
          String extName = originalFilename.substring(originalFilename.lastIndexOf(".") + 1);
  
          try {
              // 创建 fastDFS 客户端
              FastDFSClient fastDFSClient = new FastDFSClient("classpath:config/fdfs_client.conf");
  
              // 上传文件处理
              String path = fastDFSClient.uploadFile(file.getBytes(), extName);
  
              // 拼接返回的 url 和 ip 地址，拼装成完整的 url
              String url = FILE_SERVER_URL + path;
  
              return new Result(true, url);
          } catch (Exception e) {
              e.printStackTrace();
              return new Result(false, "上传失败");
          }
      }
  }
