jboss-deployment-structure 注入持久性单元时出错

Question

首先，这和JBAS016069: Error injecting persistence unit into CDI managed bean.” When deploying WAR with dependency to EJB-JAR是同一个问题 但是那里没有答案:(而且我没有足够的评论点，我的请求也不是问题的答案；这就是我开新票的原因。

无论如何，我有这个 jar（我们称之为 client.jar），它尝试使用在另一个 JAR（我们称之为 modele.jar）中定义的实体/daos。 在 client.jar 中，我有这段代码：

public class ImportService implements IServices {
    @EJB(mappedName = "java:global/tab.transmodel/VersionHoraireHome!org.avm.business.transmodel.VersionDAO")
private VersionDAO<VersionHoraire, Integer> vdhDao;

在 src/main/resources/META-INF 我有一个 jboss-deployment-structure.xml 文件：

<?xml version="1.0"?>
<jboss-deployment-structure
xmlns="urn:jboss:deployment-structure:1.2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<deployment>
    <dependencies>
    <module name="deployment.modele.jar"/>
    </dependencies>
</deployment>
</jboss-deployment-structure>

如果<module name="deployment.modele.jar"/> 行被注释掉，那么我有错误：

(...)

如果<module name="deployment.modele.jar"/> 行没有被注释，那么我有错误：

Caused by: java.lang.IllegalArgumentException: WFLYWELD0037: Error injecting persistence unit into CDI managed bean.

是的，我在 modele.jar (src/main/resources/META-INF) 中有一个 persistence.xml 文件，它定义了一个持久性单元：

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
         version="2.0">
<persistence-unit name="manager">
    <jta-data-source>java:/OracleDS</jta-data-source>
    <properties>
        <property name="hibernate.hbm2ddl.auto" value="update" />        
        <property name="hibernate.cache.use_second_level_cache" value="true" />   
     </properties>
</persistence-unit>

我迷路了:( 如果 JEE 大师可以提供帮助，我将不胜感激 :)

顺便说一句：wildfly11、java1.8、Eclipse。

最后，我找到了一种解决方案...我为 modele 生成了一个客户端：在我添加的 POM 中：

<generateClient>true</generateClient>
    <clientIncludes>
        <clientInclude>modele/dao/*.class</clientInclude>
        <clientInclude>modele/entity/*.class</clientInclude>
    </clientIncludes>

在客户端的 src/main/resources/META-INF/jboss-deployment-structure.xml 中：

<?xml version="1.0"?>
<jboss-deployment-structure
xmlns="urn:jboss:deployment-structure:1.2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<deployment>
    <dependencies>
        <module name="deployment.modele-client.jar" />
    </dependencies>
</deployment>
</jboss-deployment-structure>

那就行了 :) 我想知道大师会如何看待这个解决方案？这是正确的做法吗？
