引入依赖

      <!--整合redis-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

添加配置

spring.redis.host=127.0.0.1
spring.redis.port=6379
spring.redis.password=436280

使用

@PostMapping("/login")
    public CommonResp login(@Valid @RequestBody UserLoginReq req) {
        req.setPassword(DigestUtils.md5DigestAsHex(req.getPassword().getBytes()));
        CommonResp<UserLoginResp> resp = new CommonResp<>();
        UserLoginResp userLoginResp = userService.login(req);

        Long token = snowFlake.nextId();
        LOG.info("生成单点登录token：{}，并放入redis中", token);
        userLoginResp.setToken(token.toString());
        redisTemplate.opsForValue().set(token, JSONObject.toJSONString(userLoginResp), 3600 * 24, TimeUnit.SECONDS);

        resp.setContent(userLoginResp);
        return resp;
    }
