mysql AES_ENCRYPT AES_DECRYPT

--创建表 uc_dict

CREATE TABLE `uc_dict` (

  `type` varchar(32) NOT NULL,

  `item_code` varchar(20) NOT NULL,

  `item_value` blob,

  `seq` int(4) DEFAULT NULL,

  `note` varchar(100) DEFAULT NULL,

  PRIMARY KEY (`type`,`item_code`)

 //插入

 insert into uc_dict(type,item_code,item_value,seq,note)

  values(#type#,#item_code#,AES_ENCRYPT(#item_value#,'icity'),#seq#,#note#) 

  

//查询

select type,item_code,AES_DECRYPT(item_value,'icity') as item_value,seq,note from uc_dict where type=#type#

  

//java ibatis 查询

byte[]  b = (byte[])dictDomain.getDictListByType("test").get(1).get("item_value");

System.out.println(new String(b));

类似加密函数还有encode('要加密的字符串','密钥')，decode('要解密的二进制穿','密钥')

aes_encrypt和encode加密结果都是二进制串
