Question

这是我的主要方法。我在Application Context中遇到错误。我也添加了XML文件。

public class Main {
    public static void main(String[] args) throws SchedulerException {
        ApplicationContext appContext = new ClassPathXmlApplicationContext("spring/config/BeanLocations.xml");

        MailDao maildao = (MailDao)appContext.getBean("MailDao");

        MailBean mail = new MailBean();
        /** insert **/
        Scanner sc = new Scanner(System.in) ;
        System.out.println("Enter the from address\n");
        String fromAdd = sc.nextLine();
        mail.setFromAdd(fromAdd);

        System.out.println("Enter the To address\n");
        String toAddress = sc.nextLine();
        mail.setToAdd(toAddress);

        System.out.println("Enter the  Subject\n");
        String sub = sc.nextLine();
        mail.setSubject(sub);

        System.out.println("Enter the  Message\n");
        String msg = sc.nextLine();
        mail.setMessage(msg);

        mail.setAttachements(null);

        /*for getting current time */
        Calendar calendar = Calendar.getInstance();
        java.util.Date now = calendar.getTime();
        java.sql.Timestamp msgdate = new java.sql.Timestamp(now.getTime());
        mail.setDate(msgdate);

        mail.setSnt_status(false);

        maildao.save(mail);
    }
}

BeanLocations.xml

        <property name="password" value="${jdbc.password}" />

Hibernate.xml

<?xml version='1.0' encoding='utf-8'?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

    <!-- Hibernate session factory -->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource">
            <ref bean="dataSource"/>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.DerbyDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>     

        <!-- Drop and re-create the database schema on startup -->
        <!--<property name="hibernate.hbm2ddl.auto">update</property>-->

        <property name="mappingResources">
            <list>
                <value>/hibernate/Mail.hbm.xml</value>
            </list>
        </property>
    </bean>
</beans>

如果我取消注释行<property name="hibernate.hbm2ddl.auto">update</property>，我会收到以下错误：

cvc-complex-type.2.3：元素'property'不能包含字符[children]，因为类型的内容类型只是元素。

现在我收到了这个错误。

在这一行

ApplicationContext appContext = new ClassPathXmlApplicationContext("spring/config/BeanLocations.xml");

Answer 1

将该属性设为

<prop key="hibernate.hbm2ddl.auto">update</prop>

在Hibernate.xml文件中的属性内部道具标记。

看起来像这样：

<property name="hibernateProperties">
    <props>
        <prop key="hibernate.dialect">org.hibernate.dialect.DerbyDialect</prop>
        <prop key="hibernate.show_sql">true</prop>
        <prop key="hibernate.hbm2ddl.auto">update</prop>
    </props>
</property>

线程“main”中的异常java.lang.NoSuchMethodError：org.springframework.beans.support.ResourceEditorRegistrar
