Oracle jdbc 插入 clob blob

Oracle 使用 clob 与 blob 插入一些比较庞大的文本或者文件，JDBC 插入时 也比较简单

表结构

CREATE TABLE test_info (
  user_id int NOT NULL,
  user_name varchar(64) NULL,
  email varchar(32) NULL,
  contentText blob not null
);

java 代码

	/**
	 * 获得数据库连接
	 * @param url
	 * @param username
	 * @param passwd
	 * @return

			DriverManager.registerDriver(new OracleDriver());
			
			conn = DriverManager.getConnection(url, username, passwd);
			
		} catch (Exception e) {
			e.printStackTrace();
		}
		return conn;
	}
	
	/**

	public static void writeBLOB() {
		/** inFile path **/
