...

最近又试着又整合spring和hibernate，之间也出现过不少问题，献上单元测试例子

只有业务层和持久层

先贴上pom.xml 文件

2.配置文件Hibernate的配置文件整合到Spring文件中了

<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">

</beans>

3.实体类

一开始无法扫描到实体类，网上查需要好几个包，后来看到实体类注解包有的已经整合到hibernate-commons-annotations中了

package com.jiyx.entity;


import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;


import org.hibernate.annotations.GenericGenerator;


@Entity
@Table(name="USERS")
public class User {
@Id
@GeneratedValue(generator="uuid")    
@GenericGenerator(name="uuid",strategy="uuid")
private String id;
private String name;
private String password;
private String idCard;

public User() {
super();
// TODO Auto-generated constructor stub
}


public String getId() {
return id;
}


public void setId(String id) {
this.id = id;
}


public String getName() {
return name;
}


public void setName(String name) {
this.name = name;
}


public String getPassword() {
return password;
}


public void setPassword(String password) {
this.password = password;
}


public String getIdCard() {
return idCard;
}


public void setIdCard(String idCard) {
this.idCard = idCard;
}

}

4.持久层

一开始持久层添加了事务，测试类里面也添加了事务，查询没有出现问题，插入的时候，控制台没有走到打印插入sql语句,事务就提前关闭了，整的我一顿好找- -‘’

package com.jiyx.dao.impl;

import java.util.List;


import javax.transaction.Transactional;


import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;


import com.jiyx.dao.UserDao;
import com.jiyx.entity.User;


@Repository("userDao")
@Transactional
public class UserDaoImpl implements UserDao {

@Autowired
private SessionFactory sessionFactory;

@Override
public void save(User user) {
sessionFactory.getCurrentSession().save(user);
}


@SuppressWarnings("unchecked")
@Override
public List<User> query() {
return sessionFactory.getCurrentSession().createQuery("from User").list();
}


}



5.业务层



package com.jiyx.service.impl;


import java.util.List;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;


import com.jiyx.dao.UserDao;
import com.jiyx.entity.User;
import com.jiyx.service.UserService;
@Service("userService")
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
@Override
public void inserts(User user) {
userDao.save(user);
}
@Override
public List<User> queryAll() {
List<User> query = userDao.query();
return query;
}


}

6.单元测试类

package com.test;


import java.util.List;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import com.jiyx.entity.User;
import com.jiyx.service.UserService;


@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class springDemo {

@Autowired
private UserService userService;

/*@Autowired
public void setPersonDao(PersonDao personDao) {
this.personDao = personDao;
}*/


@Test
public  void addTest() {
System.out.println("1234");
User user = new User();
user.setIdCard("1101001");
user.setName("admin");
user.setPassword("password");
userService.inserts(user);
}
@Test
public  void queryTest() {
System.out.println("1234");
List<User> queryAll = userService.queryAll();
for(User user:queryAll) {
System.out.println(user);
}
}
}

7.工具类

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;


public class HibernateUtils {
private static final SessionFactory sessionFactory = sessionFactory();
   private static SessionFactory sessionFactory() {
       try {
           return new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();
       } catch (Throwable ex) {
           System.err.println("Initial SessionFactory creation failed." + ex);
           throw new ExceptionInInitializerError(ex);
       }
   }
   public static SessionFactory getSessionFactory() {
       return sessionFactory;
   }
   public static void shutdown() {
       // Close caches and connection pools
       getSessionFactory().close();
   }


}
