在Openshift上部署應用程序時出錯

Question

我以前沒有在jboss應用程序服務器上部署過。嘗試在openshift上部署Java Web應用程序時出現以下錯誤。我正在使用Spring和JPA 2.0。

我applicationContext.xml

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

我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>

什麼我需要做的來解決這個問題？

Answer 1

您的項目設置如何？項目是否使用jboss 7.1.0 Final在本地運行？我使用了一個persistence.xml文件，它爲我的JPA 2.0配置定義了我的EntityManagerFactory和hibernate.dialect。位於我的META-INF目錄中。這是我在我的項目中設置的方式。

<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> 

Answer 2

你應該嘗試設置hibernate.dialet屬性，使JBoss的加載持久化上下文沒有連接（可使用連接檢測方言）。它將等待從應用程序獲取連接（在您的情況下爲Spring）。

您可以設置它在persistence.xml還是應該放置在classpath

Answer 3

我得到了同樣的異常的根目錄hibernate.properties是可能的。 3-4天后，我意識到我的persistance.xml的位置不正確。我有使用EJB，JSF，MAVEN，MYSQL的EAR Web應用程序。所以，在我的eclipse中，我有ejb項目，web項目，ear項目和主項目。我正在更新EJB項目下的META-INF文件夾內的persistance.xml文件。但是，我忘了在Web Project undre JPA Content中更新相同的東西。因此，您會在您的Web項目的META-INF文件夾下找到相同的persistance.xml文件。默認情況下，unit-name將是'project-name-web'和class。因此，請根據你在這裏提到的相同的方法更新它，包括jta-datasource屬性，它應該可以工作 Mine正在工作。最後，假設！
