我之前没有部署在 jboss 应用服务器上。尝试在openshift. 我正在使用Spring和JPA 2.0。

我的applicationContext.xml

<jee:jndi-lookup id="dataSource" jndi-name="java:jboss/datasources/MysqlDS" resource-ref="true" />

我的 standalone.xml 

<datasource jndi-name="java:jboss/datasources/MysqlDS" enabled="${mysql.enabled}" use-java-context="true" pool-name="MysqlDS">
                    <connection-url>jdbc:mysql://${env.OPENSHIFT_DB_HOST}:${env.OPENSHIFT_DB_PORT}/${env.OPENSHIFT_APP_NAME}</connection-url>
                    <driver>mysql</driver>
                    <security>
                      <user-name>${env.OPENSHIFT_DB_USERNAME}</user-name>
                      <password>${env.OPENSHIFT_DB_PASSWORD}</password>
                    </security>
                </datasource>
                <drivers>
                    <driver name="mysql" module="com.mysql.jdbc">
                        <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
                    </driver>
                </drivers>

我需要做什么来解决这个问题？

您应该尝试设置 hibernate.dialect 属性以允许 JBoss 在没有连接的情况下加载持久性上下文（它可以使用连接来检测方言）。它将等待从应用程序获取连接（在您的情况下为 Spring）。

您可以在 persistence.xml 中设置它，或者应该可以在放置在类路径根目录中的 hibernate.properties 中

你的项目设置如何？项目是否使用 jboss 7.1.0 Final 在本地运行？我使用一个persistence.xml 文件，它为我的JPA 2.0 配置定义了我的EntityManagerFactory 和hibernate.dialect。位于我的 META-INF 目录中。这就是我在我的项目中设置它的方式。

<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="userpersistence" transaction-type="RESOURCE_LOCAL">
    <provider>
        org.hibernate.ejb.HibernatePersistence
    </provider>
    <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
        <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
        <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/acctdatabase"/>
        <property name="hibernate.connection.username" value="acct-user"/>
        <property name="hibernate.connection.password" value="password"/>
    </properties>
</persistence-unit>

我得到了同样的例外。3-4 天后，我意识到我的 persistence.xml 的位置不正确。我有使用 EJB、JSF、MAVEN、MYSQL 的 EAR Web 应用程序。因此，在我的 Eclipse 中，我有 ejb 项目、web 项目、ear 项目和 main 项目。我正在更新 EJB 项目下 META-INF 文件夹中的persistance.xml 文件。但是，我忘记在 JPA 内容下的 Web 项目中更新相同的内容。因此，您将在 Web 项目的 META-INF 文件夹下找到相同的 persistence.xml 文件。默认情况下，unit-name 将是“project-name-web”和类。因此，请根据您在此处提到的相同更新该名称，包括 jta-datasource 到属性。它应该可以工作。我的工作正常。最后唷！
