無法啟動JBoss，缺少部署

Question

我在JBoss中遇到這個奇怪的錯誤。 這很奇怪，因為它正在尋找一些甚至與我當前項目無關的舊項目，並且這些舊項目也在Eclipse中從我的工作空間中刪除。

當我嘗試運行當前項目時，出現以下錯誤：

DEPLOYMENTS MISSING DEPENDENCIES:
  Deployment "jboss.j2ee:ear=BibliotheekEAR.ear,jar=BibliotheekEJB.jar,name=Bibliotheek,service=EJB3" is missing the following dependencies:
    Dependency "" (should be in state "Described", but is actually in state "** UNRESOLVED Demands 'persistence.unit:unitName=BibliotheekEAR.ear/BibliotheekJPA.jar#BibliotheekJPA' **")
  Deployment "jboss.j2ee:ear=BibliotheekEAR.ear,jar=BibliotheekEJB.jar,name=Bibliotheek,service=EJB3_endpoint" is missing the following dependencies:
    Dependency "jboss.j2ee:ear=BibliotheekEAR.ear,jar=BibliotheekEJB.jar,name=Bibliotheek,service=EJB3" (should be in state "Configured", but is actually in state "PreInstall")

DEPLOYMENTS IN ERROR:
  Deployment "" is in error due to the following reason(s): ** UNRESOLVED Demands 'persistence.unit:unitName=BibliotheekEAR.ear/BibliotheekJPA.jar#BibliotheekJPA' **
  Deployment "persistence.unit:unitName=BibliotheekEAR.ear/BibliotheekJPA.jar#BibliotheekJPA" is in error due to the following reason(s): org.hibernate.HibernateException: Hibernate Dialect must be explicitly set

有任何想法嗎？

我已經刪除了所有這些項目，所以我不知道為什么要尋找它們...

Answer 1

似乎您沒有為在應用程序中使用的數據庫正確設置Hibernate數據庫方言屬性。 嘗試像這樣在persistence.xml文件中設置數據庫方言：

<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>

如果您使用的是MySQL。 這是最常用的休眠方言列表。

從哪里刪除？ 也許要仔細檢查一下，確認它們在您使用的服務器配置的deploy或tmp目錄下沒有剩余的痕跡。
