Question

我有一个在JBoss 4.2.3上运行并连接到Oracle 10g DB的应用程序。我们重构了使用spring roo的应用程序。在尝试配置jndi之前，我们使用常规的数据库连接字符串，这很好。但是现在我们正在尝试使用jndi，当JBoss注册jndi并创建数据源bean时，当hibernate实际上必须打开连接时，它无法打开。

这是持久性单元

的配置

<persistence-unit name="persistenceUnitDev" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
        <!-- value="create" to build a new database on each run; value="update" to modify an existing database; value="create-drop" means the same as "create" but also drops tables when Hibernate closes; value="validate" makes no changes to the database -->
        <property name="hibernate.hbm2ddl.auto" value="update"/>
        <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/>
        <property name="hibernate.connection.charSet" value="UTF-8"/>
        <property name="hibernate.show_sql" value="true"/>
        <property name="hibernate.connection.datasource" value="java:jdbc.DataSourceDev"/>
        <property name="hibernate.validator.apply_to_ddl" value="false" />
        <property name="hibernate.validator.autoregister_listeners" value="false" />
        <property name="jboss.entity.manager.jndi.name" value="java:jdbc.DataSourceDev"/>
        <property name="jboss.entity.manager.factory.jndi.name" value="java:/Manager1Factory"/>
    </properties>
</persistence-unit>

的hibernate.cfg.xml

<hibernate-configuration>
<session-factory>
    <property name="connection.datasource">java:jdbc.DataSourceDev</property>
    <property name="connection.autocommit">true</property>
    <property name="connection.release_mode">after_transaction</property>
    <property name="show_sql">true</property>
    <property name="format_sql">true</property>
    <property name="use_sql_comments">true</property>
    <!--DB schema will be updated if needed -->
    <property name="hbm2ddl.auto">update</property>
</session-factory>
</hibernate-configuration>

应用程序上下文定义了db bean：

<jee:jndi-lookup id="jndiDataSource2" jndi-name="${database.jndiName}"/>


<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory">
    <property name="persistenceUnitName" value="${hibernate.persistenceunit}"/>
    <property name="dataSource" ref="jndiDataSource2"/>
</bean>

我不知道为什么hibernate似乎无法打开连接。

编辑：这是日志：

我设法解决了这个问题：

下面是我的配置。

   <persistence-unit name="persistenceUnitDev" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <properties>
        <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/>
        <property name="hibernate.connection.charSet" value="UTF-8"/>
        <property name="hibernate.connection.datasource" value="dbjndiName"/>
        <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
        <property name="hibernate.connection.autocommit" value="true"/>
        <property name="hibernate.connection.release_mode" value="after_transaction"/>
        <property name="hibernate.connection.driver_class" value="oracle.jdbc.driver.OracleDriver"/>
        <property name="show_sql" value="true"/>
        <property name="format_sql" value="true"/>
        <property name="use_sql_comments" value="true"/>
        <!--DB schema will be updated if needed -->
        <property name="hbm2ddl.auto" value="create"/>
        <property name="hibernate.connection.provider_class" value="org.hibernate.connection.DatasourceConnectionProvider"/>
    </properties>
</persistence-unit>

然后hibernate.cfg.xml为空

我的应用程序上下文是使用以下bean定义的：

<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>

<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>

<tx:annotation-driven mode="aspectj" transaction-manager="transactionManager"/>

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

<bean id="jndiTemplate" class="org.springframework.jndi.JndiTemplate">
    <property name="environment">
        <props>
            <prop key="java.naming.factory.initial">com.sun.jndi.fscontext.RefFSContextFactory</prop>
            <prop key="java.naming.provider.url">file:c:/temp</prop>
        </props>
    </property>
</bean>

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="resourceRef" value="true"/>
    <property name="jndiName" value="dbjndiName"/>
    <property name="lookupOnStartup" value="false"/>
    <property name="cache" value="true"/>
    <property name="proxyInterface" value="javax.sql.DataSource"/>
</bean>

我认为在这种情况下，更少的情况是使用Java EE JNDI查找并选择正确的数据源bean类。

Hibernate无法在JBoss中使用jndi打开与oracle 10g的连接
