无法从persistence.xml创建连接

我正在开发一个使用CDI的基本CRUD应用程序，使用PrimeFaces 5.0的JSF 2.1和通过Hibernate JPA管理的PostgreSQL数据库。这是我的pom.xml文件（我使用Eclipse创建了一个CDI项目，然后添加了pom.xml）：

然后，我的persistence.xml文件：

<?xml version="1.0" encoding="UTF-8"?>

    xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <!-- <jta-data-source>java:jboss/datasources/Spring_DB</jta-data-source> -->
        <!-- -->

        <properties>
            <!-- Properties for Hibernate -->
            <property name="hibernate.hbm2ddl.auto" value="update" />
            <property name="hibernate.show_sql" value="false" />
            <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect" />

            <!-- Hibernate parameters

            <property name="hibernate.connection.url" value="jdbc:postgresql://localhost:5432/springdb" />
            <property name="hibernate.connection.username" value="springusr" />
            <property name="hibernate.connection.password" value="springusr" /> 
            -->
            <!-- JPA parameters -->
            <property name="javax.persistence.jdbc.driver" value="org.postgresql.Driver" />
            <property name="javax.persistence.jdbc.url" value="jdbc:postgresql://localhost:5432/springdb" />
            <property name="javax.persistence.jdbc.user" value="springusr" />
            <property name="javax.persistence.jdbc.password" value="springusr" />

        </properties>
    </persistence-unit>
</persistence>

我已经使用了容器的数据源（JBoss 7.1）而没有问题，你可以在我的persistence.xml（java：jboss / datasources / Spring_DB行）中看到，我知道对于生产是最好使用容器的连接池，但是现在我想在persistence.xml中配置连接，但我尝试了不同的方法但没有成功。

使用hibernate参数或javax.persistence参数我收到此错误：

如果我删除持久性提供程序（使用hibernate参数），我得到这个：

所以，我尝试了不同的组合而没有成功。它可能是什么？

1 个答案:

答案 0 :(得分：2)

您正在将应用程序部署到使用JTA的JBoss中，并且它已经提供了XA DataSource。

您不应该使用“hibernate.connection.driver_class”，因为这仅适用于简单的开发用例（从不用于生产部署）。

如果您将一个简单的Web应用程序部署到Web容器（例如Tomcat）中，那么您将需要一个资源本地 DataSource和一个专业connection pooling solution（例如HickariCP，DBCP2， BoneCP，C3P0）。

但是您正在企业应用程序服务器中运行企业应用程序。这些应用程序服务器支持JTA，因此您应该使用应用程序服务器提供的JTA DataSource。这样，您也可以从JTA事务管理器中受益。

所以切换回JBoss喜欢的JTA交易：

<persistence-unit name="crmPU" transaction-type="JTA">
    <jta-data-source>java:jboss/datasources/Spring_DB</jta-data-source>

对于持久性提供程序，您可以尝试以下设置：

<provider>org.hibernate.ejb.HibernatePersistence</provider>

您可能还希望添加与Hibernate事务相关的属性：

hibernate.transaction.factory_class = org.hibernate.transaction.JTATransactionFactory     hibernate.transaction.manager_lookup_class = org.hibernate.transaction.JBossTransactionManagerLookup     jta.UserTransaction = java的：的JBoss /数据源/ Spring_DB
