redis中springboot的redisTemplate简单的增删查

1.

private static final Logger LOGGER = LoggerFactory.getLogger(HttpServiceImpl.class);

@Resource
private RedisTemplate redisTemplate;

@PostMapping("delete")
public Result delete(boolean flag) {
    //设置存储的过期时间
    redisTemplate.opsForValue().set("hha","dada",50, TimeUnit.SECONDS);
    //设置不过期时间的Key
    redisTemplate.opsForValue().set("kk","hhh");
    System.out.println(redisTemplate.opsForValue().get("kk"));
    //删除指定的key
    redisTemplate.delete("kk");
    studentService.removeById(2);
    return flag ?Result.ok("第一个"):Result.fail("第二个");
}

过期时间的查看命令 ttl name

在图形化界面中也可以查看redis的过期时间
