不會掃描位於Wildfly模塊中的JPA實體類

我有一些駐留在Wildfly模塊中的JPA實體類。儘管此模塊中有實體類，但模塊中沒有JPA部署描述符（persistence.xml文件）。這裏是模塊的完整路徑：不會掃描位於Wildfly模塊中的JPA實體類

{Wildfly_installation}/modules/system/layers/base/br/edu/ufca/main/ufca.jar

模塊描述符（位於同一個文件夾）：

<?xml version="1.0" encoding="UTF-8"?> 
<module xmlns="urn:jboss:module:1.3" name="br.edu.ufca"> 
    <resources> 
     <resource-root path="ufca.jar"/> 
    </resources> 

    <dependencies> 
     <module name="javax.faces.api"/> 
    </dependencies> 
</module>

現在我有一個Web應用程序，我宣佈這個模塊中META-的依賴INF \ MANIFEST.MF：

Manifest-Version: 1.0 
Class-Path: 
Dependencies: br.edu.ufca export

我也有，在Web應用程序中，persistence.xml文件在這裏我列出了位於ufca.jar模塊中的一些實體類：

<?xml version="1.0" encoding="UTF-8"?> 
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd" version="2.1"> 
    <persistence-unit name="criacao-email"> 
     <jta-data-source>java:jboss/datasources/CriacaoEmailDS</jta-data-source> 

     <class>br.edu.ufca.modelo.Setor</class> 
     <!-- more classes --> 
    </persistence-unit> 
</persistence>

的問題是，當我運行試圖加載使用EntityManager的一些實體類的Web應用程序執行的代碼，例如，我得到的例外是這樣的：

這清楚地表明， JPA提供者沒有掃描實體類。但是如果我從Web應用程序訪問Wildfly模塊中的任何類而不使用JPA，我就會成功，這表明模塊真的在應用程序的類路徑中。

這是默認行爲還是我做錯了什麼？

預先感謝您。

模塊不部署的一部分，因此不會被掃描。如果您需要掃描您的實體，則需要將其包含在您的部署中。

只是爲了確保：沒有任何解決方法？ – Marcos 2014-10-17 01:11:07

不是我所知道的。我沒有測試過，但是如果你在persistence.xml中列出了實體，它可能會工作。我不確定在這個階段之前是否會添加模塊依賴關係。 – 2014-10-20 17:51:24

你可以在我的問題中看到，我從頭開始列出了persistence.xml中的實體類。它沒有工作。 – Marcos 2014-10-21 23:01:15
