Я новичок в spring-maven-hibernate и не могу решить эту ошибку вот мой вывод консоли. Я пробовал новую зависимость в pom.xml, такую ​​как ядро ​​hibernate 5.0.1, но ничего не произошло. 

SEVERE: Servlet.service() for servlet [spring] in context with path [/FlightSearchManagement] threw exception [Request processing failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'd' defined in class path resource [applicationContext.xml]: Cannot resolve reference to bean 'template' while setting bean property 'template'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'template' defined in class path resource [applicationContext.xml]: Cannot resolve reference to bean 'mysessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mysessionFactory' defined in class path resource [applicationContext.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/boot/model/naming/ImplicitNamingStrategy] with root cause

и это мой класс ManageFlightData.java пакет 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);
    }

}

Точно так же другой класс DAO должен получить компонент "d" с той же логикой, что и выше, мое applicationContext.xml равно 

    <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>

и, наконец, pom.xml равен

Вы можете использовать аннотации @Component & @Autowired, которые являются альтернативой для инициализации bean-компонентов. Например: -

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();
    }
}

Обновите вашу версию hibernate-core в pom.xml до 5.xx.

Это должно помочь вам решить вашу проблему и следующие: Выполнив простую программу интеграции с Spring Hibernate, яполучение следующего номера
