Redis_基础

Redis 命令启动、配置密码

Redis是绿色软件，所以直接解压就能使用
配置文件为：redis.windows.conf
启动redis 服务：

redis-server.exe redis.windows.conf

启动客户端：

redis-cli.exe

默认没有给Redis配置密码，所以在配置文件中配置密码

将密码设置为123456
# requirepass foobared改成
requirepass 123456

重新启动服务端，登录客户端的时候加上 -a 密码来登录；项目中就不用密码了

redis-server.exe redis.windows.conf -h localhost -p 6379 -a 123456

存放数据类型

Redis常用命令

String

SETEX为验证码场景
SETNX集群互斥

哈希

列表

集合

有序集合

通用命令

在Spring中使用Redis

导入坐标、配置数据源、配置类

redis实际上是创建了16个数据库，互相隔离；这里写索引为0-15

操作String类型数据

使用注入的RedisTemplate

注意代码中使用的函数不是以之前命令的名称进行命名的

我们之前使用了String的序列化器，那么在redis的客户端中，key是没有乱码的；但是值有乱码；

Hash操作

列表（list）类数据：

@Test
public void testList(){//Lpush lrange rpop llenListOperations listOperations = redisTemplate.opsForList();listOperations.leftPushAll("mylist","a","b","c"); //lpush多个valuelistOperations.leftPush("mylist","d"); //lpush单个valueList mylist = listOperations.range("mylist",0,-1); //lrangeSystem.out.println(mylist);listOperations.rightPop("mylist"); //rpopLong size = listOperations.size("mylist"); //llenSystem.out.println(size);
}

集合类数据：

@Test
public void testSet(){//sadd smembers scard sinter sunion sremSetOperations setOperations = redisTemplate.opsForSet();setOperations.add("set1","a","b","c","d"); //saddsetOperations.add("set2","a","b","x","y");Set members = setOperations.members("set1"); //smembersSystem.out.println(members);Long size = setOperations.size("set1"); //scardSystem.out.println(size);Set intersect = setOperations.intersect("set1","set2"); //sinter取交集System.out.println(intersect);Set union = setOperations.union("set1","set2"); //sunion取并集System.out.println(union);setOperations.remove("set1","a","b"); //srem
}

有序集合类数据：

@Test
public void testZset(){//zadd zrange zincrby zremZSetOperations zSetOperations = redisTemplate.opsForZSet();zSetOperations.add("zset1","a",10); //zaddzSetOperations.add("zset2","b",12);zSetOperations.add("zset1","c",9);Set zset1 = zSetOperations.range("zset1",0,-1); //zrangeSystem.out.println(zset1);zSetOperations.incrementScore("zset1","c",10); //zincrbyzSetOperations.remove("zset1","a","b"); //zrem
}

通用命令

@Test
public void testCommon(){//keys exists type delSet keys = redisTemplate.keys("*"); //keysSystem.out.println(keys);Boolean name = redisTemplate.hasKey("name"); //existsBoolean set1 = redisTemplate.hasKey("set1");for(Object key : keys){DataType type = redisTemplate.type(key); //typeSystem.out.println(type.name());}redisTemplate.delete("mylist"); //del
}
