java - 用户必须提供 JDBC 连接

Question

我有一个 DispatcherServlet.xml 文件，它的 hibernate 文件配置为

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="mappingResources">
        <list>
            <value>com/dibya/hbm/resource/model.hbm.xml</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.username">root</prop>
            <prop key="hibernate.password"></prop>
            <prop key="hibernate.url">jdbc:mysql://localhost/test</prop>
            <prop key="hibernate.driver_class">com.mysql.jdbc.Driver</prop>
            <prop key="hibernate.show_sql">false</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
        </props>
    </property>
</bean>

<bean id = "hibernateTemplate" class = "org.springframework.orm.hibernate3.HibernateTemplate">
    <property name = "persister">
        <ref bean = "sessionFactory"/>
    </property>
</bean>

在我的 Controller 中，我有

@RequestMapping(value = "Hello.htm")
public String HelloWorld(Model model) {
    boolean is = persister.isAllowCreate();

    Person person = new Person();
    person.setName("dibya");
    persister.saveOrUpdate(person);

    System.out.println("This is called"+is);
    return "HelloWorld";
}

我收到此错误消息:

HTTP Status 500 - Request processing failed; nested exception is java.lang.UnsupportedOperationException: The user must supply a JDBC connection

请告诉我我忘了添加什么。

您的 hibernate 配置文件使用了错误的参数名称。正确的参数名称如下:

hibernate.connection.driver_class
hibernate.connection.url
hibernate.connection.username
hibernate.connection.password
hibernate.dialect
hibernate.show_sql

更正您的参数名称并重试。

编辑:有关参数名称的详细列表，请参阅此链接:http://docs.jboss.org/hibernate/core/3.3/reference/en/html/session-configuration.html
