## 序列化 ##

防止乱码：

// key序列化
    redisTemplate.setKeySerializer(STRING_SERIALIZER);
    // value序列化
    redisTemplate.setValueSerializer(JACKSON__SERIALIZER);
    // Hash key序列化
    redisTemplate.setHashKeySerializer(STRING_SERIALIZER);
    // Hash value序列化
    redisTemplate.setHashValueSerializer(JACKSON__SERIALIZER);
    redisTemplate.afterPropertiesSet();

## String ##

//插入字符串
      redisTemplate.opsForValue().set("String","String");

## List ##

//插入集合
    List<String> strings1 = new ArrayList<>();
    strings1.add("LIST1");
    strings1.add("LIST2");
    strings1.add("LIST2");
    for (String str:strings1){
        redisTemplate.opsForList().leftPush("list1",str);//左插入
        redisTemplate.opsForList().rightPush("list2",str);//右插入
    }

**注意对比左右插入的区别。**

## Set ##

//插入set集合
    Set<String> set1 = new HashSet<>();
       set1.add("set1");
       set1.add("set2");
       set1.add("set3");
       set1.add("set3");
    for (String str:set1){
        redisTemplate.opsForSet().add("set",str);
    }

## Map ##

//插入map
    redisTemplate.opsForHash().put("hash","hashKey1","hashValue1");
    redisTemplate.opsForHash().put("hash","hashKey2","hashValue2");

## zset ##

//插入zset
    redisTemplate.opsForZSet().add("zset","hello", 1);
    redisTemplate.opsForZSet().add("zset","hi", 2);
    redisTemplate.opsForZSet().add("zset","nihao", 3);
