Question

我正在尝试配置Spring 3.2，Maven 3项目以使用Hibernate 4.1，但我似乎遇到了我的Persistence.xml和/或我的entityManagerFactory的问题。

我正在尝试遵循JPA规范。

运行应用程序时出现以下错误：

[见下图]

我对可能出现的问题有一些想法，但不知道如何解决可能出错或可能出错的问题。首先，我不确定我是否在persistence.xml文件中配置了hibernate.connection.url属性。（这是资源/ META-INF。）“jdbc：oracle：thin：@ PC55555.oururl.com：1521：psychos”psychos是SID，但架构名称是Daredevils。此外，“hibernate.hbm2ddl.auto”属性是否适用于Oracle 11g？

这是我的persistence.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
    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">

    <persistence-unit name="MyPersistence"
        transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <properties>
        <property name="dialect" value="org.hibernate.dialect.OracleDialect" />
            <property name="hibernate.connection.driver_class" value="oracle.jdbc.driver.OracleDriver" />
            <property name="hibernate.connection.url"
                value="jdbc:oracle:thin:@PC55555.oururl.com:1521:psychos" />

            <property name="hibernate.connection.username" value="theusername" />
            <property name="hibernate.connection.password" value="thepassword" />
            <property name="hibernate.hbm2ddl.auto" value="create" />
        </properties>
    </persistence-unit>
</persistence>

就Hibernate的Spring配置而言，这是我的hibernate-context.xml文件（在我的基本弹簧配置xml文件中导入）。当entityManagerFactory声明它的持久性单元属性时，似乎抛出了错误，所以我认为这里没有什么问题。

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

Answer 1

首先，确保正确设置连接。如果pyschos是sid，只要其他属性（如端口和服务器）都可以，就应该找到它。 oracle JDBC url应遵循以下语法：

JDBC：预言：瘦：[USER / PASSWORD] @ [HOST] [：端口]：SID

还要确保DareDevils被用作具有相应密码的用户名。

其次我不相信您需要配置JpaVendorAdapter，因为您依赖persistence.xml文件来定义持久性提供程序<provider>org.hibernate.ejb.HibernatePersistence</provider>，这会将实体管理器配置更改为：

<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="persistenceUnitName" value="MyPersistence" />
</bean>

Oracle确实支持hibernate.hbm2ddl.auto。

您可能还想查看我的博客中描述如何设置Spring Data项目的视频教程，其中包含有关如何为实体管理器创建配置的说明：http://tothought.cloudfoundry.com/post/3

Answer 2

该属性称为 hibernate.dialect ，而不仅仅是 dialect 。这应该至少让你通过这个初始异常。

Answer 3

Lame修复，但我转而使用基于Java的弹簧配置，当我首先不需要persistence.xml或任何xml配置时，我能够让它正常工作！

使用Spring和Maven设置Hibernate时出现EntityManagerFactory错误
