mysql读取text 大文本

读取mysql数据库文本字段的值方法如下：

public void read() {

try {

//连接数据库

conn = JdbcUtils.getConnection()

//查询resume字段，text格式

String sql = "select resume from testclob where id=1"

pt = conn.prepareStatement(sql)

//执行查询并返回结果

rs = pt.executeQuery()

if (rs.next()) {

// rs.getCharacterStream读取该字段

Reader reader = rs.getCharacterStream("resume")

//定义字符数组来存放读取值

char buffer[] = new char[1024]

while ((reader.read(buffer)) != -1) {

//打印

System.out.println(buffer)

}

reader.close()

}

} catch (Exception e) {

e.printStackTrace()

} finally {

JdbcUtils.release(conn, pt, rs)

}

}
