org.jboss.weld.exceptions.DeploymentException：WELD-001409：具有限定符 @Default 的类型 Bean 的依赖性不明确
org.jboss.weld.exceptions.DeploymentException: WELD-001409: Ambiguous dependencies for type Bean with qualifiers @Default
我的项目昨天运行良好。我唯一做的就是将结构从单个 war 更改为多模块 pom。如果我正确理解堆栈跟踪，那么 weld 和 omnifaces websocket lib 之间存在歧义。但是，在堆栈跟踪中似乎没有对我的任何方法的任何调用。所以也许这是 omnifaces 的问题？我什至不使用 omnifaces websockets，我使用 javax.websocket。然而，我过去确实在这个项目中尝试过，我在 "org.omnifaces.cdi" 上进行了搜索，并从 @Param 等子包中注释掉了一些东西，但问题仍然存在。
我也不明白为什么歧义似乎来自 2 个完全相同的 类:
- Managed Bean [class org.omnifaces.cdi.push.SocketSessionManager] with qualifiers [@Any @Default],
- Managed Bean [class org.omnifaces.cdi.push.SocketSessionManager] with qualifiers [@Any @Default]

基本上，Weld 发现了多个 CDI 管理的 bean，这些 bean 可以注入 SocketPushContextProducer class 的 private SocketSessionManager socketSessions 字段中。它们列在后面：
Possible dependencies:
- Managed Bean [class org.omnifaces.cdi.push.SocketSessionManager] with qualifiers [@Any @Default]
- Managed Bean [class org.omnifaces.cdi.push.SocketSessionManager] with qualifiers [@Any @Default]
在这个特定的例子中，它们是完全一样的。这意味着运行时class路径中有多个SocketSessionManagerclasses。这反过来意味着在运行时 class 路径中存在多个 OmniFaces libraries/dependencies（或脏构建/（热）部署，这可以通过破坏服务器的 work/temp 文件夹或生成一个干净的服务器实例）。
您需要确保运行时 class路径中只有一个 OmniFaces 库，并且它最终位于 WAR 的 /WEB-INF/lib。
这与 websockets 没有特别的关系。它恰好是 Weld 扫描的第一个与 OmniFaces 相关的 class。它可能发生在 OmniFaces 中捆绑的任何其他 CDI 托管 bean 上。
也有可能只是pom版本变更，maven构建缓存不一致。
