数据操作

String

/*** 设置key的string* @param value* @return*/
@GetMapping("sstr")
public String setString(String value){try {redisTemplate.opsForValue().set("name", value);} catch (Exception e) {return e.getMessage();}return "SUCCESS";
}/*** 获取key的string* @param key* @return*/
@GetMapping("gstr")
public String getString(String key){return JSON.toJSONString(redisTemplate.opsForValue().get(key));
}

List

/*** 设置key的list集合* @param sons* @param key* @return*/
@PostMapping("/slist/{key}")
public String setUser(@RequestBody List<Son> sons,@PathVariable("key") String key){try {redisTemplate.opsForList().leftPushAll(key, sons);} catch (Exception e) {return e.getMessage();}return "SUCCESS";
}/*** 获取key的list集合* @param key* @return*/
@GetMapping("/glist")
public List<Son> getSon(String key){return redisTemplate.opsForList().range(key, 0, -1);
}

Set

/*** 设置key的set集合* @param key* @param sons* @return*/
@PostMapping("sadd/{key}")
public String sadd(@PathVariable("key") String key, @RequestBody Set<Son> sons){try {redisTemplate.opsForSet().add(key, sons);} catch (Exception e) {return e.getMessage();}return "SUCCESS";
}/*** 获取key的set集合* @param key* @return*/
@GetMapping("smembers")
public Set<Son> smembers(String key){Set members = redisTemplate.opsForSet().members(key);return members;
}

Zset

/*** 向redis中添加zset集合* @param key* @param sons* @return*/
@PostMapping("zadd/{key}")
public String zadd(@PathVariable("key")String key, @RequestBody Set<Son> sons){try {Set<DefaultTypedTuple<Son>> set = new HashSet<>();sons.forEach(item -> {double random = Math.random();DefaultTypedTuple<Son> typedTuple = new DefaultTypedTuple<>(item, random);set.add(typedTuple);});redisTemplate.opsForZSet().add(key, set);} catch (Exception e) {return e.getMessage();}return "SUCCESS";
}/*** 获取zset集合范围元素* @param key* @param start* @param end* @return*/
@GetMapping("zrange")
public Set<Son> zrange(String key, Integer start, Integer end){Set range = redisTemplate.opsForZSet().range(key, start, end);return range;
}

Hash

/*** 设置redis key 的hash值* @param key* @param sonMap* @return*/
@PostMapping("hmset/{key}")
public String hmSet(@PathVariable("key") String key,@RequestBody Map<String, Son> sonMap){try {redisTemplate.opsForHash().putAll(key, sonMap);} catch (Exception e) {return e.getMessage();}return "SUCCESS";
}/*** 获取redis中key的hash* @param key* @return*/
@GetMapping("hmget")
public Map hmget(String key){return redisTemplate.opsForHash().entries(key);
}
