JBoss as7 到 WildFly 的 Hibernate 迁移

Question

我尝试从 JBoss AS 7 迁移到 Wildfly 8.2。而且我在休眠方面确实有问题。

我正在使用带有依赖项的 maven：

<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-entitymanager</artifactId>
  <version>4.2.0.Final</version>
</dependency>

和

<dependency>
  <groupId>org.hibernate.javax.persistence</groupId>
  <artifactId>hibernate-jpa-2.0-api</artifactId>
  <version>1.0.1.Final</version>
</dependency>

当我在 AS 7 中启动我的应用程序时，我在 wildfly 中遇到错误：

10:08:11,485 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 53) MSC000001: Failed to start service jboss.persistenceunit."com.haslerrail.MyDatabase.web.war#MyDatabase": org.jboss.msc.service.StartException in service jboss.persistenceunit."com.haslerrail.MyDatabase.web.war#MyDatabase": javax.persistence.PersistenceException: [PersistenceUnit: MyDatabase] Unable to build Hibernate SessionFactory

我试图找到任何有关 hibernate 和 wildfly 的文档，但 https://docs.jboss.org/author/display/WFLY8/Hibernate 上的文档是空的！！！！

有人有从 AS 7 迁移到 Wildfly 和 hibernate 的经验吗？我需要调整什么？

Answer 1

Hibernate 的容器版本优先于 Java EE 容器中的应用程序打包版本。因此出现错误。

为避免这种情况，您需要显式控制类加载并排除容器库。阅读here

基本上，您需要提供jboss-deployment-structure.xml 以对依赖项进行细粒度控制。

例如：

    <jboss-deployment-structure>
        <deployment>
            <exclusions>
                <!-- Exclude container version of hibernate. By default its version 4, we want 
                    bundled version to load -->
                <module name="org.hibernate" slot="main" />
            </exclusions>
        </deployment>
    </jboss-deployment-structure>

Answer 2

经过几个小时的尝试，这个版本的 jboss-deployment-structure.xml 文件似乎对我有用：

<jboss-deployment-structure>
  <deployment>
    <exclusions>
      <module name="org.hibernate" slot="main" />
    </exclusions>
    <dependencies>
      <module name="org.hibernate" />
    </dependencies>
  </deployment>
</jboss-deployment-structure>

我认为我还需要“org.hibernate”作为依赖项，因为我正在使用 Flyway 进行数据库迁移......否则我会收到一些错误消息。

没有 Flyway，Rohit 的答案似乎是正确的......（但我还没有测试过！）
