注入RedisTemplate

@Resource
private RedisTemplate redisTemplate;

将map整个存入redis

Map<String,Boolean> map = new HashMap<>(2);
map.put("1",true);
map.put("2",false);
redisTemplate.opsForHash().putAll(“redis键”,map);

保存map值到指定key true为map的值

redisTemplate.opsForHash().put("redis键","map键",true);

获取整个map

redisTemplate.opsForHash().entries("redis键");

根据map键获取map值

redisTemplate.opsForHash().get("redis键","map键");

根据redis键和map键删除对应值 map键传数组可删除多个

redisTemplate.opsForHash().delete(“redis键”, "map键");

获取是否存在redis键

Boolean flag = redisTemplate.hasKey(“redis键”);

根据redis键删除

Boolean flag = redisTemplate.delete(“redis键”);
