使用nginx 做代理登录出现了问题(求解)

Question

nginx 配置如下

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

代码如下：

@Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
       /* Config config = new Config();
        config.useSingleServer()
                .setAddress("redis://127.0.0.1:6379");
        RedissonClient redissonClient = Redisson.create(config);
        String resourceName="REDLOCK_KEY";
        RLock lock= redissonClient.getLock(resourceName);
        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);
            if (isLock) {
                log.info("JWTFilter  doFilterInternal  :time:"+ DateFormatUtils.format(new Date(),"yyyy-MM-dd hh:mm:ss"));
                //从url中根据参数获取值
                String jwt = obtainParameter(request, GlobalConstant.jwt);
                Authentication authentication=null;
                if (StringUtils.hasText(jwt)) {
                    getAuthentication( jwt ,response);

                }
                filterChain.doFilter(request, response);
            }
        } catch (Exception e) {
            log.error(e.getMessage());
        } finally {
            redLock.unlock();
        }*/
        log.info("JWTFilter  doFilterInternal  :time:"+ DateFormatUtils.format(new Date(),"yyyy-MM-dd hh:mm:ss"));
        //从url中根据参数获取值
        String jwt = obtainParameter(request, GlobalConstant.jwt);
        Authentication authentication=null;
        if (StringUtils.hasText(jwt)) {
            getAuthentication( jwt ,response);

        }
        filterChain.doFilter(request, response);
    }

现象如下：

问题：

为什么在doFilterInTernal 直接相互调用导致无法登录

不知道你这个问题是否已经解决, 如果还没有解决的话:

• 你可以参考下这篇文章：基于nginx代理实现短链接跳转

如果你已经解决了该问题, 非常希望你能够分享一下解决方案, 以帮助更多的人 ^-^
