dbutils实现clob和blob存储

   //使用dbutils实现大文本对象的存储.      @Test      public void testClob() throws Exception{          String sql="insert into article (content)values(?)";          File file=new File("bin/stylesheet.css");          char[] c=new char[(int)file.length()];          FileReader reader=new FileReader(file);          reader.read(c);          SerialClob clob=new SerialClob(c);          QueryRunner runner=new QueryRunner(JDBCUtils.getDataSource());          runner.update(sql, clob);        }      //使用dbutils实现二进制对象的存储.      @Test      public void testBlob() throws Exception{          String sql="insert into image (content)values(?)";          File file=new File("bin/bg.jpg");          byte[] b=new byte[(int)file.length()];          InputStream in=new FileInputStream(file);          in.read(b);          SerialBlob blob=new SerialBlob(b);          QueryRunner runner=new QueryRunner(JDBCUtils.getDataSource());          runner.update(sql,blob);      }
