Question

我的应用程序使用的是Spring 4，Hibernate 4，Java 1.7。这是桌面应用程序而不是Web应用程序，因此不涉及服务器。我正在尝试创建与数据库的连接。为了简洁起见 - 我无法复制和粘贴 - 我遗漏了一些非必要的东西来解决这个问题。这是我的春季配置：

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    <property name="driverClass" value="oracle.jdbc.OracleDriver" />
    <property name="jdbcUrl" value="jdbc:oracle:thin:@dbServer:1521:service" />
    <property name="properties">
        <props>
            <prop key="user">user</prop>
            <prop key="password">password</prop>
        </props>
    </property>
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan" value="com.help.please" />
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.connection.autocommit">true</prop>
        </props>
    </property>

<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

我已将sessionFactory自动装入DAO。当我尝试从sessionFactory获取连接时，日志看起来像是这样（再次缩短）：

我成功地使用用户使用其他应用程序以及SQL Developer登录数据库。 我已多次确认用户/密码是否正确。我已尝试同时使用ojdbc6.jar和ojdbc7.jar，希望它可能就是这样。我做了一些研究，发现可能是用户名/密码在被发送到Oracle之前可能会被自动大写，但我知道知道验证的方法。

可能很重要的一点是，当我使用Spring 3和Hibernate 3时，这段代码正好连接到数据库。有关如何解决这个问题的建议吗？

修改

重要的是要注意我正在使用注释和xml的组合来配置我的项目。我正在使用@Autowired来注入我的服务，daos和会话工厂。我在我的dao图层中使用@Transactional和@Repository。我不知道这是否有所作为，但请看下面的答案，看看我是如何运作的。

Answer 1

我发现我需要在{spring hibernate.cfg.xml bean中添加sessionFactory文件。

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="connection.url">jdbc:oracle:thin:@dbServer:1521:service</property>
        <property name="connection.username">user</property>
        <property name="connection.password">password</property>
        <property name="connection.driver_class">oracle.jdbc.OracleDriver</property>
        <property name="hibernate.connection.autocommit">true</property>
        <property name="dialect">org.hibernate.dialect.Oracle10gDialect</property>
        <property name="hibernate.show_sql">true</property>
    </session-factory>
</hibernate-configuration>

现在我的弹簧配置改为：

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    <property name="driverClass" value="oracle.jdbc.OracleDriver" />
    <property name="jdbcUrl" value="jdbc:oracle:thin:@dbServer:1521:service" />
    <property name="user" value="user" />
    <property name="password" value="password" />
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan" value="com.help.please" />
    <property name="configLocation">
        <value>classpath:com.help.please/hibernate.cfg.xml</value>
    </property>
</bean>

<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

我不太清楚为什么会这样做的解释，但我认为的方式向我解释的是，属性并没有全部传递给Hibernate所以像这样配置Hibernate和Spring一样可以帮助它获得所需的正确配置。如果我错了，请随时纠正我。
