nginx 配置如下

upstream crserver {
#ip_hash;
server 127.0.0.1:8090;
server 127.0.0.1:8091;
}
代码：
@Override

/* Config config = new Config();
config.useSingleServer()

RedissonRedLock redLock = new RedissonRedLock(lock);
boolean isLock;
try { // isLock = redLock.tryLock(); // 500ms拿不到锁, 就认为获取锁失败。10000ms即10s是锁失效时间。
isLock = redLock.tryLock(500, 10000, TimeUnit.MILLISECONDS);
log.info("lock is "+isLock);

问题：
为什么在doFilter这里相互调用导致没有进入登录逻辑
