在Maven-Spring-Hibernate中找不到Bean错误

我是spring-maven-hibernate的新手，我无法解决以下错误 这是我的控制台输出。我在pom.xml中尝试了新的依赖关系，例如5.0.1休眠核心，但是什么也没发生。

这是我的类ManageFlightData.java类     包com.xyz.dao; 

import java.util.List;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;

import com.xyz.input.FlightDataInput;
import com.xyz.model.FlightData;

public class ManageFlightData {

    public static void insertFlightData(FlightData flightData) {
        Resource r = new ClassPathResource("applicationContext.xml");
        BeanFactory factory = new XmlBeanFactory(r);
        FlightDataDAO dao = (FlightDataDAO) factory.getBean("e");
        dao.saveFlightData(flightData);
    }

    public static List<FlightData> searchFlights(FlightDataInput input) {
        Resource r = new ClassPathResource("applicationContext.xml");
        System.out.println("in search");
        BeanFactory factory = new XmlBeanFactory(r);
        FlightDataDAO dao = (FlightDataDAO) factory.getBean("e");
        return dao.searchFlights(input);
    }

}

同样，另一个DAO类应该使用与上述相同的逻辑来获取bean“ d”， 我的applicationContext.xml是

    <bean id="mysessionFactory"
        class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="mappingResources">
            <list>
                <value>UserData.hbm.xml</value>
                <value>FlightData.hbm.xml</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop 
    key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>
    </bean>

    <bean id="template"
        class="org.springframework.orm.hibernate5.HibernateTemplate">
        <property name="sessionFactory" ref="mysessionFactory"></property>
    </bean>
        <bean id="d" class="com.xyz.dao.UserDataDAO">
            <property name="template" ref="template"></property>
        </bean>

        <bean id="e" class="com.xyz.dao.FlightDataDAO">
            <property name="template" ref="template"></property>
        </bean>
    </beans>

最后pom.xml是

将pom.xml中的休眠核心版本更新为5.x.x。

这应该可以帮助您解决问题以及后续的问题： By executing a simple program of Spring Hibernate integration, I am getting following issue

您可以使用注释@Component和@Autowired，这是初始化bean的替代方法。 例如：-

CustomerDAO.java 

@Component
public class CustomerDAO 
{
    @Override
    public String toString() {
        return "Hello , This is CustomerDAO";
    }   
}

CustomerService.java 

@Component
public class CustomerService 
{
    @Autowired
    CustomerDAO customerDAO;

    public String test() {
        return customerDAO.toString();
    }
}
