在Openshift上部署应用程序时出错

标签： mysql spring java-ee jboss openshift

我之前没有部署在jboss应用服务器上。尝试在openshift上部署Java Web应用程序时出现以下错误。我使用的是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>

我需要做些什么才能解决此问题？

您的项目如何设置？该项目是否使用jboss 7.1.0 Final在本地运行？我使用persistence.xml文件为我的JPA 2.0配置定义了我的EntityManagerFactory和hibernate.dialect。位于我的META-INF目录中。这就是我在项目中设置的方式。

<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>

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化上下文（它可以使用连接来检测方言）。它将等待从应用程序获得连接（在您的情况下为Spring）。

您可以在persistence.xml中设置它，或者可以在放置在类路径的根目录中的hibernate.properties中设置它

我得到了同样的例外。 3-4天后，我意识到我的persistance.xml的位置不正确。我有使用EJB，JSF，MAVEN，MYSQL的EAR Web应用程序。所以，在我的日食中，我有ejb项目，web项目，ear项目和主项目。我正在更新persistance.xml文件，该文件位于EJB项目下的META-INF文件夹中。但是，我忘了在Web Project undre JPA Content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persistance.xml文件。默认情况下，unit-name将是'project-name-web'和类。所以，更新那个与你在这里提到的相同，包括jta-datasource到属性。它应该工作。 我正在工作。最后。呼！
