springmvc+mybatis框架集成redis

1、redis存数据(注册时将数据同时存入redis)

    //存入redis缓存
    redisService.initializationAccount(pd);

2、redisService中的写法

public UserAccount initializationAccount(PageData pd){
        UserAccount account = new UserAccount();
        try {
            PageData pageData = accountService.redisAccountList(pd);
//          account.setU_id(pageData.getString("u_id"));
            account.setID(pageData.getString("ID"));
            account.setHx_id(pageData.getString("hx_id"));
            account.setNick_name(pageData.getString("nick_name"));
            setAccount(pageData.getString("u_id"), account);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return account;
    }
    A、redisAccountList数据从数据库中查询，mybatis写法如下：
    <select id="RedisAccount" parameterType="pd" resultType="pd">
    SELECT 
            IFNULL((SELECT u_id FROM bit_user WHERE u_id= #{u_id}),0) AS u_id,
            IFNULL((SELECT ID FROM bit_user WHERE u_id= #{u_id}),0) AS ID,
            IFNULL((SELECT hx_id FROM bit_user WHERE u_id= #{u_id}),0) AS hx_id,
            IFNULL((SELECT nick_name FROM bit_user WHERE u_id= #{u_id}),0) AS nick_name
    </select>


    B、setAccount方法存入数据
public void setAccount(String key,UserAccount accont){
        if(StringUtils.isNotBlank(key) && accont != null){
            RedisUtils redisUtils = new RedisUtils(jedisPool);
            redisUtils.setObject("U"+key, accont, 0);
        }
    }
    C、setObject方法见上篇redis工具类博客中的RedisUtils类

3、redis取值：

UserAccount accont = redisService.getAccont(pd.getString("uid"));//从redis中取值
system.out.print(accont.getNick_name());//测试数据是否打印
A、getAccont方法在redisService中：
public UserAccount getAccont(String id){
        UserAccount accont;
        RedisUtils redisUtils = new RedisUtils(jedisPool);
        accont = (UserAccount)redisUtils.getObject("U"+id);
        if(accont == null ){
            accont = new UserAccount();
        }
        return accont;
    }
