Java_webservices上传文件

用WebService传输文件，实际上就是客户端将文件先做成比特流，然后调用webservice接口，服务端再将比特流还原成文件。下面是代码：

public class FileTransferWs {
      public int uploadFile(byte[] bs, String fileName){
          FileOutputStream out=null ;
          try {
              String newFile = "C:\tmp\" + fileName;// 上传文件存放路径
              out = new FileOutputStream(newFile);
              try { out.write(bs); } catch (IOException e){ e.printStackTrace(); }
          }catch (FileNotFoundException e)   {
              e.printStackTrace();
              return -1;
          }finally {
              if(out!=null){try{ out.close(); } catch (IOException e){ e.printStackTrace(); } }
          }
          return 0 ;
      }
}

客户端

public class FileUpload {
      public static void main(String []args)throws Exception {
          FileTransferWsProxy p = new FileTransferWsProxy();// 生成webservice代理对象
          String filePath   =   " E:\Book\权证基础知识.pdf " ;
          String fileName   =   " 权证基础知识.pdf " ;
          File file   =   new   File(filePath);
          FileInputStream in   =   new   FileInputStream(file);
          byte   []bs   =   new   byte [in.available()];
          in.read(bs);
          in.close();
          System.out.println( " 正在传输文件" "    +   fileName   +   " " " );
          p.uploadFile(bs, fileName);   // 调用webservice进行文件上传
          System.out.println( " 文件传输完毕 " );
      }
}
