Spring标注开发的Junit测试

       上一篇就针对spring开发时的2种方式给予Junit测试的一个简单说明。这篇为了给新人们一个明确的说明，我就直接符上代码，供大家参考；

1.实体类：

package com.tta.model;

public class User implements java.io.Serializable {
	private Integer id;
	private String name;
	private Integer age;
	private String address;

	public User() {
	}

	public User(Integer age, String address) {
		this.age = age;
		this.address = address;
	}

	public User(String name, Integer age, String address) {
		this.name = name;
		this.age = age;
		this.address = address;
	}

	public Integer getId() {
		return this.id;
	}

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

	public String getName() {
		return this.name;
	}

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

	public Integer getAge() {
		return this.age;
	}

	public void setAge(Integer age) {
		this.age = age;
	}

	public String getAddress() {
		return this.address;
	}

	public void setAddress(String address) {
		this.address = address;
	}

}

 实体orm映射文件：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
    <class name="com.tta.model.User" table="tb_model_user" >
        <id name="id" type="integer">
            <column name="id" />
            <generator class="native"></generator>
        </id>
        <property name="name" type="string">
            <column name="name" length="20" />
        </property>
        <property name="age" type="integer">
            <column name="age" not-null="true" />
        </property>
        <property name="address" type="string">
            <column name="address" length="50" not-null="true" />
        </property>
    </class>
</hibernate-mapping>

 2.服务层代码：

package com.tta.svc;

import java.util.List;

import com.tta.model.User;

public interface IUserService {
	
	void saveUser(User u);
	
	void deleteUser(User u);
	
	void updateUser(User u);
	
	User findUserById(int userId);
	
	List<User> findUsers();
}

 

package com.tta.svc.impl;

import java.util.List;

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

import com.tta.dao.IUserDao;
import com.tta.model.User;
import com.tta.svc.IUserService;

@Service("userService")
@Transactional
public class UserService implements IUserService {
	private IUserDao useDao;
	@Override
	public void deleteUser(User u) {
		useDao.deleteUser(u);
	}

	@Override
	public User findUserById(int userId) {
		return useDao.findUserById(userId);
	}

	@Override
	public List<User> findUsers() {
		return useDao.findUsers();
	}

	@Override
	public void saveUser(User u) {
		useDao.saveUser(u);
	}

	@Override
	public void updateUser(User u) {
		useDao.updateUser(u);
	}

	public void setUseDao(IUserDao useDao) {
		this.useDao = useDao;
	}

}

 

3.数据操作层：

package com.tta.dao;

import java.util.List;

import com.tta.model.User;

public interface IUserDao {
	
	void saveUser(User u);
	
	void deleteUser(User u);
	
	void updateUser(User u);
	
	User findUserById(int userId);
	
	List<User> findUsers();
}

 

package com.tta.dao.impl;

import java.util.List;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;

import com.tta.dao.IUserDao;
import com.tta.model.User;

@Repository("userDao")
public class UserDao extends HibernateDaoSupport implements IUserDao {
	@Autowired
	public void setSuperSessionFactory(SessionFactory sessionFactory) {
		super.setSessionFactory(sessionFactory);
	}
	
	@Override
	public void deleteUser(User u) {
		getHibernateTemplate().delete(u);
	}

	@Override
	public User findUserById(int userId) {
		User u = new User();
		u.setId(userId);
		return (User) getHibernateTemplate().findByExample(u).get(0);
	}

	@Override
	public List<User> findUsers() {
		//Model User
//		return getHibernateTemplate().find("from User");
		//View User
		return getHibernateTemplate().find("select new User(age,address) from User");
	}

	@Override
	public void saveUser(User u) {
		getHibernateTemplate().save(u);
	}

	@Override
	public void updateUser(User u) {
		getHibernateTemplate().merge(u);
	}
	
}

 

4.spring配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context-2.5.xsd">
    
    <context:annotation-config />
    
	<context:component-scan base-package="com.tta.*" />

	<bean id="dataSource"
		class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName"
			value="com.mysql.jdbc.Driver">
		</property>
		<property name="url" value="jdbc:mysql://127.0.0.1:3306/mbpa"></property>
		<property name="username" value="root"></property>
		<property name="password" value="sainwind"></property>
	</bean>
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource">
			<ref bean="dataSource"></ref>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">
					org.hibernate.dialect.MySQLDialect
				</prop>
			</props>
		</property>
		<property name="mappingResources">
			<list>
				<value>com/tta/model/User.hbm.xml</value>
			</list>
		</property>
	</bean>
</beans>

 

 

 

最后，贴上我们的测试类：

package com.tta.svc.test;

import java.util.List;

import org.junit.Test;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.tta.model.User;
import com.tta.svc.IUserService;
import com.tta.svc.impl.UserService;

public class UserTest {
	private static ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
	private static AutowireCapableBeanFactory autoBeanFactory = applicationContext.getAutowireCapableBeanFactory();
	private static IUserService svc = (UserService)autoBeanFactory.getBean("userService");
//	@Test
	public void save(){
		User u = new User(22,"zhangsan");
		svc.saveUser(u);
	}
//	@Test
	public void delete(){
		svc.deleteUser(svc.findUserById(1));
	}
//	@Test
	public void update(){
		User u = svc.findUserById(1);
		u.setAddress("上海市徐汇区零陵路123号");
		u.setAge(35);
		u.setName("赵冰");
		svc.updateUser(u);
	}
	@Test
	public void getUsers(){
		List<User> users = svc.findUsers();
		for(User u : users){
			System.out.println("name : "+u.getName()+" address:"+u.getAddress());
		}
	}
}

 有问题可以一起探讨啊。希望大家多多指点。
