springboot 程序运行一段时间，页面就会处于pending状态，必须得重启jar包，利用jstack查看信息，如下（只贴了一段代码），请大神帮忙看看什么原因

其中.com.elens.util.RedisUtil.get(RedisUtil.java:126)代码如下：
public Object get(String key) {
System.out.println("redis的key： " + key);
return (key == null || StringUtils.isBlank(key)) ? null : redisTemplate.opsForValue().get(key);
}
貌似多线程进入死锁了
获取非公平锁失败
如有帮助，请采纳，谢谢
从错误日志中可以看出，一个线程在等待获取一个ReentrantLock的NonfairSync锁。同时，该日志还显示了该线程在执行的过程中涉及到了Redis的操作，具体在com.elens.util.RedisUtil.get(RedisUtil.java:126)方法。
问题可能是由于在Redis操作中，并发的线程竞争获取ReentrantLock锁，导致某些线程一直WAITING（等待）状态并阻塞。
解决方法有以下几点建议：
lock.unlock() 释放锁。tryLock() 方法代替 lock() 方法以避免线程阻塞。 tryLock() 方法将尝试获取锁，如果锁可用，线程将继续执行，否则将立即返回并避免阻塞。
