?如下代码，经过测试的！O(∩_∩)O哈哈~

?

数据库：oracle9

驱动 ： ojdbc14_g.jar

?

注意：不同的版本、不同的驱动写法不一样....?

??? 这里是写clob ??

 DataSource dataSource = jdbcTemplate.getDataSource();
				  try {
					    Connection conn  =  dataSource.getConnection(); 
					    PreparedStatement stmt = conn.prepareStatement("update zyfiles set txt=?  where  href = '"+filename+"'");
					    //将字符串转行为流的形式
					    Reader clobReader = new StringReader(sBuffer.toString());
					    stmt.setCharacterStream(1, clobReader, sBuffer.toString().length());
						int num = stmt.executeUpdate();
						if (num > 0) {
							System.out.println(filename+"成功");
						}else {
							System.out.println(filename+"失败======================");
						}
					    stmt.close();
						conn.close();
					} catch (Exception e) {  
					}
