DaoImpl中的Field Dao需要一个名为'entityManagerFactory＆＃39;的bean。无法找到

Question

我的错误信息如下：

***************************
APPLICATION FAILED TO START
***************************

Description:

Field visitorDao in com.ahmed.service.VisitorDaoImpl required a bean named 'entityManagerFactory' that could not be found.


Action:

Consider defining a bean named 'entityManagerFactory' in your configuration.

请按以下课程进行。我无法理解编译器想要说什么。

以下是classess。

package com.ahmed.service;

import com.ahmed.dao.VisitorDao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class VisitorDaoImpl {

    @Autowired
    VisitorDao visitorDao;


}

这是另一个......

package com.ahmed.dao;

import com.ahmed.domain.Visitor;
import java.time.LocalDateTime;
import java.util.List;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;

/**
 *
 * @author abhiramagopaladasa
 */
@Repository
public interface VisitorDao extends CrudRepository<Visitor, Integer>{
    List<Visitor> findByOutTime(LocalDateTime outTime);
    List<Visitor> findByInTime(LocalDateTime outTime);

}

我也有HibernateConfiguration类：

        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(new String\[\] { "com.ahmed.domain" });
        sessionFactory.setHibernateProperties(hibernateProperties());
        return sessionFactory;
     }

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
        dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
        dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
        dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
        return dataSource;
    }

    private Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
        properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));

        return properties;        
    }

    @Bean
    @Autowired

       HibernateTransactionManager txManager = new HibernateTransactionManager();
       txManager.setSessionFactory(s);
       return txManager;
    }

任何帮助将不胜感激。据我所知，我已经完成了所需的一切。我不知道我错过了什么。我是否需要另一个类配置entityManager或其他什么？
