在过去的24小时中，我遇到了一个奇怪的问题，即部署一个Spring Boot应用程序，该应用程序在上一次更改之前一直可以正常工作。
我们最终发现，只要删除某些HttpSecurity过滤器链（特别是.antMatchers（）），Java构建就可以正常工作。
值得一提的是，例如在使用像STS这样的IDE时，不会出现此问题。
在WebSecurityConfig文件中具有超过332个.antMatchers（）时，我们面临的错误如下：

如前所述，只要我们从文件中删除7-10 .antMatchers（），就不会出现此问题。
问题是：HttpSecurity过滤器接受的链数是否有限制？在这种情况下，是否有大量匹配规则的替代方案？
