我正在尝试将 war 文件部署到 Wildfly 10.0.0.Final，部署失败并出现以下错误：

假设 JBoss AS7 的战争运行良好。这种行为的可能根本原因是什么？

似乎不是 bean 存档的 WAR 缺少 org.jboss.as.weld.WeldStartService 依赖项。但是这个问题怎么解决呢？

但是如何解决这个问题呢？

不要在AfterDeploymentValidation 之前使用BeanManager.getReference。相应地重构您的代码。原因是 - getReference 可能会给您不完整的结果。此时，引导程序尚未完成，getReference 方法可能无法检索引用，因为在给定时间可能没有引用（尽管稍后会出现）。

至于如何解决这个问题：

使用 Weld non-portable mode 尽管这可能会产生更多不良影响。您应该首先尝试重构代码，然后再回退到此配置。
