Redis使用及工具类

【学会安装redis】
从redis.io下载最新版redis-X.Y.Z.tar.gz后解压，然后进入redis-X.Y.Z文件夹后直接make即可，安装非常简单。
make成功后会在src文件夹下产生一些二进制可执行文件，包括redis-server、redis-cli等等：
代码如下:
$ find . -type f -executable
./redis-benchmark //用于进行redis性能测试的工具
./redis-check-dump //用于修复出问题的dump.rdb文件
./redis-cli //redis的客户端
./redis-server //redis的服务端
./redis-check-aof //用于修复出问题的AOF文件
./redis-sentinel //用于集群管理
【学会启动redis】
启动redis非常简单，直接./redis-server就可以启动服务端了，还可以用下面的方法指定要加载的配置文件：
代码如下:
./redis-server ../redis.conf
./redis-server ../redis.conf
默认情况下，redis-server会以非daemon的方式来运行，且默认服务端口为6379。
【使用redis客户端】
代码如下:
//这样来启动redis客户端了
$ ./redis-cli
//用set指令来设置key、value
127.0.0.1:6379> set name "roc"
OK
//来获取name的值
127.0.0.1:6379> get name
"roc"
//通过客户端来关闭redis服务端
127.0.0.1:6379> shutdown
127.0.0.1:6379>
【redis数据结构 – 简介】
redis是一种高级的key:value存储系统，其中value支持五种数据类型：
1.字符串（strings）：由于INCR等指令本身就具有原子操作的特性，所以我们完全可以利用redis的INCR、INCRBY、DECR、DECRBY等指令来实现原子计数的效果
2.字符串列表（lists）：lists的常用操作包括LPUSH、RPUSH、LRANGE等。我们可以用LPUSH在lists的左侧插入一个新元素，用RPUSH在lists的右侧插入一个新元素，用LRANGE命令从lists中指定一个范围来提取元素。
我们可以利用lists来实现一个消息队列，而且可以确保先后顺序，不必像MySQL那样还需要通过ORDER BY来进行排序。
利用LRANGE还可以很方便的实现分页的功能。
在博客系统中，每片博文的评论也可以存入一个单独的list中
3.字符串集合（sets）
4.有序字符串集合（sorted sets）：很多时候，我们都将redis中的有序集合叫做zsets，这是因为在redis中，有序集合相关的操作指令都是以z开头的，比如zrange、zadd、zrevrange、zrangebyscore等等
5.哈希（hashes）
而关于key，有几个点要提醒大家：
1.key不要太长，尽量不要超过1024字节，这不仅消耗内存，而且会降低查找的效率；
2.key也不要太短，太短的话，key的可读性会降低；
3.在一个项目中，key最好使用统一的命名模式，例如user:10000:passwd。
【聊聊redis的事务处理】
众所周知，事务是指“一个完整的动作，要么全部执行，要么什么也没有做”。
在聊redis事务处理之前，要先和大家介绍四个redis指令，即MULTI、EXEC、DISCARD、WATCH。这四个指令构成了redis事务处理的基础。
1.MULTI用来组装一个事务；
2.EXEC用来执行一个事务；
3.DISCARD用来取消一个事务；
4.WATCH用来监视一些key，一旦这些key在事务执行之前被改变，则取消事务的执行。
redis存在的好处就在于无需频繁的访问数据库，当一些数据不会发生变化时可以直接添加到redis中，比如聊天一些历史记录等，类似于缓存，这样大大的提高了性能，建议在使用redis最好结合着数据库一起使用。
Redis使用示例：
int user_id = 2;//用户id String user_name;//用户名 if(jedis.hexists("user"+user_id, "user_name")){//判断jedis中是否存在"user"+user_id哈希表并且value值为user_name user_name =jedis.hget("user"+user_id, "user_name");//如果存在直接获取然后登陆 System.out.println("欢迎来到Redis登陆: "+user_name); }else{//如果不存在，则需要查询数据库判断用户名密码是否正确，如果存在则登陆，并且将其信息保存至redis String sql = "select user_name from user_t where id = "+user_id+""; try { ResultSet rs = conn.createStatement().executeQuery(sql); if(rs.next()){ jedis.hset("user"+user_id, "user_name", rs.getString("user_name"));//保存至redis中 System.out.println("欢迎来到MySql登陆: "+rs.getString("user_name")); }else{ System.out.println("欢迎 注册"); } } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); }
