Question

部署獎勵-jsf應用程序時出現以下錯誤。請指教。

Answer 1

DefaultUserGroupInfoProducer應該已經被標記爲替代，因此需要在beans.xml中指定它來檢測它，是這種情況嗎？如果是這樣，從beans.xml中刪除它應該禁用它。

Answer 2

這是肯定的問題：org.jboss.weld.exceptions.DeploymentException：通過引起 類型[UserGroupCallback] WELD-001409曖昧的依賴關係：在需要的UserGroupCallBack 注射點 - > @注入專用的org.jbpm.examples.util.RewardsApplicationScopedProducer.usergroupCallback]。

1）第一可能的匹配： [[管Bean [類org.jbpm.examples.util.RewardsUserGroupCallback]與限定符[@Any @default]，

2）第二匹配度：生產者方法[UserGroupCallback]限定符[@Any @Default]聲明爲[[method] @ApplicationScoped @Produces public org.jbpm.kie.services.cdi.producer.DefaultUserGroupInfoProducer.produceCallback（）]]]

其中一個必須離開爲了工作。我想RewardsUserGroupCallback是這個應用程序的入口（我真的不知道這個應用程序託管在哪裏或它的內部），所以你需要查看代碼。
