我目前正在将这些应用程序部署到Wildfly 8.x
当我使用部署后启动的单例部署jar时，我能够按预期使用DAO。我正在从数据库得到结果
但是，当我尝试将依赖项设置为jar（在MANIFEST.MF或jboss deployment structure.xml中）的war部署时，我总是得到一个错误，即Weld无法将持久性单元注入DAO bean，因为它找不到具有我指定名称的持久性单元：
JBAS016069:将持久性单元注入CDI托管bean时出错。在deployment test.war中找不到名为test的持久性单元

这是一个奇怪的错误，因为对于war，容器不需要persistence.xml文件，因为它位于加载dao类的ejb jar中

那么，为什么容器会抱怨缺少持久性单元，尽管它存在于jar中呢

EntityManager（ejb jar）的注入：

  @PersistenceContext(unitName="test")

我刚刚将文件persistence.xml从“..\src\main\java\META-INF”移到“..\src\main\webapp\META-INF”中，它就工作了。如果classes文件夹中没有META-INF/persistence.xml文件，war将不起作用。

您可以介绍如何使用

@PersistenceContext

、您的

persistence.xml

和日志吗？什么是

persistence.xml

路径<代码>世界大战和测试战争是一回事，对吗？您只在这个DAO中使用了

@PersistenceContext

？war文件是相同的，我修改了错误日志以匹配描述的名称@PersistenceContext仅在DAO中使用，persistence.xml位于ejb jar/META-INF/下。刀也在那里，如果我在这个罐子里的另一个bean中使用它，它就可以很好地工作！我发现这种行为是由CDI引起的。如果使用DAO为EJBJAR启用CDI以便将DAO注入Servlet，那么一旦您将JBoss依赖项从war设置到jar，CDI就会抱怨缺少持久性单元。问题是，为了让DAO在类路径上进行注入，需要这种依赖关系
