本文详细介绍了在MyEclipse2014环境中，如何将Spring和Hibernate集成到项目中，并通过JUnit进行单元测试。包括项目配置、组件安装、数据库连接设置、DAO层实现及反向工程生成Bean等关键步骤。

环境:MyEclipse2014

步骤:

1.创建项目,导入mysql connector到lib下

2.右击项目名->MyEclipse->Project facets->install Spring... 弹出窗口后,之间点击finish.

3.同步骤2->install hibernate ,出现窗口后点击next(如图)

next,这里我使用的是JDBC.

点击finish.

4.利用反向工程(reverse engineering,具体使用请百度).创建bean

5.这里就不写service了,直接在dao上测试出结果,创建DAO

package glut.dao;

import javax.annotation.Resource;

import glut.bean.Admin;

import org.hibernate.SessionFactory;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.stereotype.Component;

@Component("adminDAO")
public class AdminDAO {
	private SessionFactory sessionFactory;

	@Test
	public void test() {
		ApplicationContext context = new ClassPathXmlApplicationContext(
				"applicationContext.xml");
		AdminDAO ad = context.getBean(AdminDAO.class);
		ad.add(new Admin());
	}

	public void add(Admin admin) {
		System.out.println("Adding");
	}

	public SessionFactory getSessionFactory() {
		return sessionFactory;
	}

	@Resource(name = "sessionFactory")
	public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}

}

6.别急着测试,这里还有小问题,applicationContext.xml里应该添加

<context:annotation-config></context:annotation-config>
<context:component-scan base-package="glut"></context:component-scan>

(我这里的包明明是以glut.*命名的),完整代码:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<bean id="dataSource"
		class="org.apache.commons.dbcp.BasicDataSource">
		<property name="url" value="jdbc:mysql://localhost:3306/test"></property>
		<property name="username" value="user"></property>
		<property name="password" value="1234"></property>
	</bean>
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">
					org.hibernate.dialect.MySQLDialect
				</prop>
			</props>
		</property>
		<property name="annotatedClasses">
			<list>
				<value>glut.bean.Admin</value></list>
		</property></bean>
	<bean id="transactionManager"
		class="org.springframework.orm.hibernate4.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>
	<tx:annotation-driven transaction-manager="transactionManager" />
	<context:annotation-config></context:annotation-config>
	<context:component-scan base-package="glut"></context:component-scan>
</beans>

最后,运行JUnit即可.
