SpringBoot--RedisTemplate详解（Hash、Set、ZSet）

Redis的Hash数据结构

Redis的散列可以让用户将多个键值对存储到一个Redis键里面。
public interface HashOperations<H,HK,HV>
HashOperations提供一系列方法操作hash：

初始数据:
//template.opsForHash().put("redisHash","name","tom");
        //template.opsForHash().put("redisHash","age",26);
        //template.opsForHash().put("redisHash","class","6");

//Map<String,Object> testMap = new HashMap();
        //testMap.put("name","jack");
        //testMap.put("age",27);
        //testMap.put("class","1");
        //template.opsForHash().putAll("redisHash1",testMap);

Long delete(H key, Object… hashKeys);
删除给定的哈希hashKeys

使用：System.out.println(template.opsForHash().delete("redisHash","name"));
        System.out.println(template.opsForHash().entries("redisHash"));
结果：1
{class=6, age=28.1}

Boolean hasKey(H key, Object hashKey);
确定哈希hashKey是否存在

使用：System.out.println(template.opsForHash().hasKey("redisHash","age"));
        System.out.println(template.opsForHash().hasKey("redisHash","ttt"));
结果：true
false

HV get(H key, Object hashKey);
从键中的哈希获取给定hashKey的值

使用：System.out.println(template.opsForHash().get("redisHash","age"));
结果：26

List multiGet(H key, Collection hashKeys);
从哈希中获取给定hashKey的值

使用：List<Object> kes = new ArrayList<Object>();
        kes.add("name");
        kes.add("age");
        System.out.println(template.opsForHash().multiGet("redisHash",kes));
结果：[jack, 28.1]

Long increment(H key, HK hashKey, long delta);
通过给定的delta增加散列hashKey的值（整型）

使用：System.out.println(template.opsForHash().get("redisHash","age"));
    System.out.println(template.opsForHash().increment("redisHash","age",1));
结果：26
27

Double increment(H key, HK hashKey, double delta);
通过给定的delta增加散列hashKey的值（浮点数）

使用：System.out.println(template.opsForHash().get("redisHash","age"));
    System.out.println(template.opsForHash().increment("redisHash","age",1.1));
结果：27
28.1

Set keys(H key);
获取key所对应的散列表的key

使用：System.out.println(template.opsForHash().keys("redisHash1"));
//redisHash1所对应的散列表为{class=1, name=jack, age=27}
结果：[name, class, age]

Long size(H key);
获取key所对应的散列表的大小个数

使用：System.out.println(template.opsForHash().size("redisHash1"));
//redisHash1所对应的散列表为{class=1, name=jack, age=27}
结果：3

Long size(H key);
获取key所对应的散列表的大小个数

使用：System.out.println(template.opsForHash().size("redisHash1"));
//redisHash1所对应的散列表为{class=1, name=jack, age=27}
结果：3

void putAll(H key, Map<? extends HK, ? extends HV> m);
使用m中提供的多个散列字段设置到key对应的散列表中

使用：Map<String,Object> testMap = new HashMap();
        testMap.put("name","jack");
        testMap.put("age",27);
        testMap.put("class","1");
        template.opsForHash().putAll("redisHash1",testMap);
        System.out.println(template.opsForHash().entries("redisHash1"));
结果：{class=1, name=jack, age=27}

void put(H key, HK hashKey, HV value);
设置散列hashKey的值

使用：template.opsForHash().put("redisHash","name","tom");
        template.opsForHash().put("redisHash","age",26);
        template.opsForHash().put("redisHash","class","6");
System.out.println(template.opsForHash().entries("redisHash"));
结果：{age=26, class=6, name=tom}

Boolean putIfAbsent(H key, HK hashKey, HV value);
仅当hashKey不存在时才设置散列hashKey的值。

使用：System.out.println(template.opsForHash().putIfAbsent("redisHash","age",30));
System.out.println(template.opsForHash().putIfAbsent("redisHash","kkk","kkk"));
结果：false
true

使用：System.out.println(template.opsForHash().entries("redisHash"));
结果：{age=26, class=6, name=tom}

Cursor<Map.Entry<HK, HV>> scan(H key, ScanOptions options);
使用Cursor在key的hash中迭代，相当于迭代器。

使用：Cursor<Map.Entry<Object, Object>> curosr = template.opsForHash().scan("redisHash", ScanOptions.ScanOptions.NONE);
        while(curosr.hasNext()){
            Map.Entry<Object, Object> entry = curosr.next();
            System.out.println(entry.getKey()+":"+entry.getValue());
        }
结果：age:28.1
class:6
kkk:kkk

Redis的Set数据结构

Redis的Set是string类型的无序集合。集合成员是唯一的，这就意味着集合中不能出现重复的数据。
Redis 中集合是通过哈希表实现的，所以添加，删除，查找的复杂度都是O(1)。
public interface SetOperations<K,V>
SetOperations提供了对无序集合的一系列操作：

Long add(K key, V… values);
无序集合中添加元素，返回添加个数
也可以直接在add里面添加多个值如：template.opsForSet().add(“setTest”,“aaa”,“bbb”)

使用：String[] strarrays = new String[]{"strarr1","sgtarr2"};
        System.out.println(template.opsForSet().add("setTest", strarrays));
结果：2

Long remove(K key, Object… values);
移除集合中一个或多个成员

使用：String[] strarrays = new String[]{"strarr1","sgtarr2"};
System.out.println(template.opsForSet().remove("setTest",strarrays));
结果：2

V pop(K key);

Redis的ZSet数据结构

Redis 有序集合和无序集合一样也是string类型元素的集合,且不允许重复的成员。
不同的是每个元素都会关联一个double类型的分数。redis正是通过分数来为集合中的成员进行从小到大的排序。
有序集合的成员是唯一的,但分数(score)却可以重复。

结果：true

Long add(K key, Set<TypedTuple> tuples);
新增一个有序集合

使用：ZSetOperations.TypedTuple<Object> objectTypedTuple1 = new DefaultTypedTuple<Object>("zset-5",9.6);
        ZSetOperations.TypedTuple<Object> objectTypedTuple2 = new DefaultTypedTuple<Object>("zset-6",9.9);
        Set<ZSetOperations.TypedTuple<Object>> tuples = new HashSet<ZSetOperations.TypedTuple<Object>>();
        tuples.add(objectTypedTuple1);
        tuples.add(objectTypedTuple2);
        System.out.println(template.opsForZSet().add("zset1",tuples));
