在 EAP 6.4.0 中使用 JPA 2.1 [英] Using JPA 2.1 in EAP 6.4.0

问题描述

我一直在寻找解决这个问题的方法，但没有成功.

I searched for a solution for this problem without having success so far.

我们正在将应用程序迁移到 EAP 6.4.0，而我们的应用程序依赖于 JPA 2.1.但是，JBoss 是 Java EE 6 服务器，因此以模块的形式包含 JPA 2.0.

We're migrating our aplications over to EAP 6.4.0, and our applications relies on JPA 2.1. However, JBoss is a Java EE 6 server, and therefore includes JPA 2.0 in the form of a module.

我尝试将 JPA API jar 直接包含在我的 WEB-INF/lib 目录中，认为类加载器更喜欢这个而不是系统中的那个.

I tried including the JPA API jar directly in my WEB-INF/lib directory, thinking the classloader would prefer this one over the one from the system.

我试图在我的耳朵中包含一个 jboss-deployment-structure.xml 文件.我在ear/META-INF、ear/war/META-INF和ear/war/WEB-INF下试过.

I have tried to include a jboss-deployment-structure.xml file in my ear. I tried it under ear/META-INF, ear/war/META-INF, and ear/war/WEB-INF.

在 jboss-deployment-structure.xml 文件中，我尝试:排除 javax.persistence.api 模块使用 JPA 2.1 创建我自己的模块并为其添加依赖项排除jpa子系统

In the jboss-deployment-structure.xml file, I tried to: exclude the javax.persistence.api module create my own module with JPA 2.1 and add a dependency to it exclude the jpa subsystem

我还尝试将位于 jboss-eap-6.4.0modulessystemlayersasejavaxpersistenceapimain 下的 javax.persistence.api module.xml 文件中的导出属性设置为 false

I also tried to set the export attribute to false in the javax.persistence.api module.xml file located under jboss-eap-6.4.0modulessystemlayersasejavaxpersistenceapimain

我尝试从 standalone.xml 中删除 jpa 子系统.

I tried removing the jpa subsystem from the standalone.xml.

所有这些都导致使用 JPA 2.0 jar.

All of these things resulted in the JPA 2.0 jar being used.

我让它工作的唯一方法是替换模块目录中的实际 jar (jboss-eap-6.4.0modulessystemlayersasejavaxpersistenceapimain).但这不是一个有效的解决方案，因为服务器中的其他应用或服务实际上可能需要旧版本的 API.

The only way I got it to work was to replace the actual jar in the module directory (jboss-eap-6.4.0modulessystemlayersasejavaxpersistenceapimain). But that's not a valid solution as other apps or services in the server may actually need the old version of the API.

有没有办法正确执行此操作(无需迁移到另一台服务器或更改代码)?

Is there a way to do this correctly (without migrating to another server nor changing the code)?

推荐答案

请看:https://issues.jboss.org/browse/WFCORE-209

这是上面链接的副本:

解决方法 1

更新javaee/api/main.module.xml如下:

update the javaee/api/main.module.xml as followed:

<!--<module name="javax.persistence.api" export="true"/>-->

虽然这是不可移植的.

解决方法 2

更新 jboss-deployment-structure.xml 如下:

update jboss-deployment-structure.xml as followed:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <exclude-subsystems>
            <subsystem name="jpa" />
        </exclude-subsystems>
        <exclusions>
            <!-- WFCORE-209 workaround -->
            <module name="javaee.api" />
            <!-- --------------------- -->
            <module name="javax.persistence.api" />
            <module name="org.hibernate" />

            <module name="javax.ws.rs.api" export="true"  services="export"/>
            <module name="javax.xml.bind.api" export="true"/>
            <module name="javax.xml.registry.api" export="true"/>
            <module name="javax.xml.soap.api" export="true"/>
            <module name="javax.xml.ws.api" export="true"/>

            <!-- This one always goes last. -->
            <module name="javax.api" export="true"/>
            <!-- --------------------- -->
        </dependencies>
    </deployment>
</jboss-deployment-structure>

这是完全便携的
