oracle存储图片，用BLOB出现的问题。求教。
代码如下：
String URL = "jdbc:oracle:thin:@127.0.0.1:1521:XE"; Statement stmt; try { Class.forName("oracle.jdbc.driver.OracleDriver"); Connection conn = DriverManager.getConnection(URL, "userName", "passwd"); stmt = conn.createStatement(); String sql = "select d_image from display_table where autoid=1 for update"; ResultSet rs =stmt.executeQuery(sql); if (rs.next()) { oracle.sql.BLOB blob = (oracle.sql.BLOB) rs.getBlob(1); File file = new File("D:\\test.png"); //getBinaryOutputStream(); 这个方法已经过期，不知道用哪个替代 OutputStream outStream = blob.getBinaryOutputStream(); InputStream fin = new FileInputStream(file); byte[] b = new byte[blob.getBufferSize()]; int leng = 0; while ( (leng = fin.read(b)) != -1) { outStream.write(b, 0, leng); } } }catch (ClassNotFoundException cnf) { System.out.println("driver not find:" + cnf); } catch (SQLException sqle) { System.out.println("can't connection db:" + sqle); } catch (Exception e) { System.out.println("Failed to load JDBC/ODBC driver."); };Connection conn = null; Statement stmt = null; ResultSet rs = null; OutputStream os = null; try { stmt = conn.createStatement(); conn.setAutoCommit(false); stmt.executeUpdate("insert into t_image (id, image) values (2, empty_blob())"); rs = stmt.executeQuery("select image from t_image where id=2 for update"); if (rs.next()) { oracle.sql.BLOB blob = (oracle.sql.BLOB) rs.getBlob("image"); os = blob.getBinaryOutputStream(); InputStream is = new FileInputStream("D:/a.jpg"); byte[] b = new byte[blob.getBufferSize()]; int i = 0; while ((i = is.read(b)) != -1) { os.write(b,0,i); } } os.flush(); os.close(); conn.commit(); conn.setAutoCommit(true);// 恢复现场
