CAS v7.0.0重启间歇性死锁问题求助（从v6.6.2迁移后）

近期将应用从CAS v6.6.2迁移至v7.0.0后，遇到重启时间歇性卡顿的问题，线程dump中检测到明确的死锁。

已尝试以下解决方案，但均无效果：

• 设置lazy initialization为false
• 创建过滤器在启动阶段拦截所有请求
• 延迟Dispatcher Servlet初始化

目前怀疑问题根源在于CAS v7.0.0中广泛使用的@RefreshScope与@Lazy注解组合，该判断基于Spring相关Issue中的死锁场景——其附件里的死锁情况与我们的线程dump完全一致。

线程dump堆栈信息如下：
