SpringBoot操作Redis的5种数据类型

@GetMapping("/string")
public String stringTest(){
    redisTemplate.opsForValue().set("str", "Hello, World");
    String str = (String)redisTemplate.opsForValue().get("str");
    return str;
}

@GetMapping("/list")
public List listTest(){
    redisTemplate.opsForList().leftPush("list", "Java");
    redisTemplate.opsForList().leftPush("list", "Python");
    redisTemplate.opsForList().leftPush("list", "C++");
    List list = redisTemplate.opsForList().range("list",0, -1);
    return list;
}

@GetMapping("/set")
public Set setTest(){
    redisTemplate.opsForSet().add("set", "aaa","bab", "jsp");
    Set set = redisTemplate.opsForSet().members("set");
    return set;
}

@GetMapping("/zSet")
public Set zSetTest(){
    redisTemplate.opsForZSet().add("zSet", "aaa", 10);
    redisTemplate.opsForZSet().add("zSet", "bbb", 2);
    redisTemplate.opsForZSet().add("zSet", "aba", 30);
    Set zSet = redisTemplate.opsForZSet().range("zSet", 0, -1);
    return zSet;
}

HashMap：key-value

HashOperations：key-hashKey-value

key是每一组数据的ID，hashKey和value是一组完整的HashMap数据，通过key来区分不同的HashMap。

HashMap hashMap1 = new HashMap();
hashMap1.put(key1, value1);

HashMap hashMap2 = new HashMap();
hashMap2.put(key1, value1);

HashMap hashMap3 = new HashMap();
hashMap3.put(key1, value1);

HashOperations hashOperations = redisTemplate.opsForHash();
hashOperations.put(hashMap1, key1, value1);
hashOperations.put(hashMap2, key1, value1);
hashOperations.put(hashMap2, key1, value1);

@GetMapping("/hash")
public HashMap hashTest(){
    redisTemplate.opsForHash().put("millingForce", "xForce", 10);
    redisTemplate.opsForHash().put("millingForce", "yForce", 20);
    redisTemplate.opsForHash().put("millingForce", "zForce", 80);
    HashMap map = (HashMap) redisTemplate.opsForHash().entries("millingForce");
    return map;
}
