将文档以BLOB类型存入Oracle数据库中

头痛了两天的问题终于得到解决了，特此写下(原创)：

 

conn.setAutoCommit(false);
      Statement stmt = conn.createStatement();
      int i = stmt.executeUpdate("insert into TESTTWO values(4,Empty_BLOB(),'/dqpisei/')");
      ResultSet rs = stmt.executeQuery("select BLOB from TESTTWO where ID = 4 for update");
      if(rs.next()){
        oracle.sql.BLOB blob = (BLOB)rs.getBlob("BLOB");
        PrintStream ps = new PrintStream(blob.getBinaryOutputStream());
        File file = new File("H:\\film\\移动互联网的关键技术IPv6.pdf");
//        File file = new File("F:\\课程论文.doc");
        BufferedInputStream bis = new BufferedInputStream(new FileInputStream(
            file));
        byte[] buff = new byte[1024];
        int n = 0;

        while ( (n = bis.read(buff)) != -1) {
          ps.write(buff, 0, n);
        }
        ps.flush();
        ps.close();
        bis.close();
      }
      rs.close();
      stmt.close();
      conn.close();
      System.out.println( " i : " + i);
