在SpringBoot中如何利用Redis实现互斥锁

   /**
     * 根据name对特定的数据进行锁
     * @param name
     * @return
     */
public boolean setLock(String name) {
    return Boolean.TRUE.equals(redisTemplate.opsForValue().setIfAbsent(name, true, 10, TimeUnit.SECONDS));
}
public boolean releaseLock(String name) {
    return Boolean.TRUE.equals(redisTemplate.delete(name));
}

@GetMapping("/getOneByLock/{sequence}")
public BaseResponse<Sentences> getOneByLock(@PathVariable long sequence) {
    // 从redis中查信息
    String name = "test:redis:sentences:"+ sequence;
    Sentences sentence = (Sentences) redisTemplate.opsForValue().get(name);
    // 命中返回数据
    if(sentence != null ){
        redisTemplate.expire(name,2,TimeUnit.MINUTES);
        return ResultUtils.success(sentence);
    }
    // 未命中获取锁
    String LOCK_NAME = "test:redis:lock:" + sequence;
    boolean lock = redisTemplate.opsForValue().get(LOCK_NAME) != null && (boolean) redisTemplate.opsForValue().get(LOCK_NAME);
    //如果lock等于false 那么就可以获取到锁并且，锁住不许其他人操作
    if(!lock){
       return ResultUtils.success(setLockReleaseLockAboutSentence(LOCK_NAME,name,sequence));
    }
    // 没有获取到锁 休眠一段时间，并且反复检测redis中的数据是否存在，或者锁是否释放
    while(true){
        try {
            Thread.sleep(1000);

    // 设置 锁值 为true
    setLock(LOCK_NAME);
    // 并且从数据中查取数据
    Sentences sentence = sentencesService.getById(sequence);
    // 这里为了明显不能抢锁设置一个睡眠时间
    try {
