String

RedisTemplate

@SpringBootApplication
@RestController
public class RedisApplication {

    @Resource
    private RedisTemplate redisTemplate;

    public static void main(String[] args) {
        SpringApplication.run(RedisApplication.class, args);
    }

    @GetMapping("/get/{key}")
    public Object getKey(@PathVariable("key") String key){
        return redisTemplate.opsForValue().get(key);
    }

    @PostMapping("/set")
    public boolean setKey(String key, String v){
        redisTemplate.opsForValue().set(key,v);
        return redisTemplate.hasKey(key);
    }
}

StringRedisTemplate

@SpringBootApplication
@RestController
public class RedisApplication {

    @Resource
    private StringRedisTemplate stringRedisTemplate;

    public static void main(String[] args) {
        SpringApplication.run(RedisApplication.class, args);
    }

    @GetMapping("/get/{key}")
    public Object getKey(@PathVariable("key") String key){
        return stringRedisTemplate.opsForValue().get(key);
    }

    @PostMapping("/set")
    public boolean setKey(String key, String v){
        stringRedisTemplate.opsForValue().set(key,v);
        return stringRedisTemplate.hasKey(key);
    }
}

测试

启动redis

win + r 输入 cmd

切换至redis安装目录"xxxxx\Redis-x64-3.2.100"

输入"redis-server.exe"回车

或者

直接打开"Redis-x64-3.2.100"文件夹，地址栏输入"cmd"按Enter键

输入"redis-server.exe"回车

 若输入"redis-server.exe"回车报错redis无法启动可以输入"redis-server.exe redis.windows.conf"回车

 generated-requests.http

直接点击下图箭头所示

或者直接创建 generated-requests.http都可以
