4、使用
在需要使用redisClient的地方注入
@Autowired private RedisClient redisClient;
调用redisClient方法执行增删改查
//不存在就新增 if( !redisClient.exists(auth.getName())){ redisClient.set(redisKey,userInfo.toString()); } //存在才可以删除 if( redisClient.exists(auth.getName())){ redisClient.del(redisKey); } //获取 String userInfo = redisClient.get(username);
效果：通过查询redis可以看到数据成功的插入到redis了
127.0.0.1:6379> KEYS * 1) "user1"
127.0.0.1:6379> get user1 "user1;pwd2;b1f86e0a-8761-4467-b420-48d9783d3806;tl21uazmvnd4v3ee4bunesms;ROLE_USER"
