maven+Spring环境搭建

一，项目结构图

二，applicationContext.xml

<?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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
     http://www.springframework.org/schema/beans
     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
     http://www.springframework.org/schema/tx
     http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
     http://www.springframework.org/schema/aop
     http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
     http://www.springframework.org/schema/context
     http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <bean id="personDao" class="com.deppon.test04.dao.impl.PersonDao"></bean>

    <bean id="personService" class="com.deppon.test04.service.impl.PersonService">
        <property name="personDao" ref="personDao"></property>
    </bean>

</beans>

三，service

package com.deppon.test04.service;

public interface IPersonService {

    public void processSave();
}

package com.deppon.test04.service.impl;

import com.deppon.test04.dao.IPersonDao;
import com.deppon.test04.service.IPersonService;

public class PersonService implements IPersonService {
    private IPersonDao personDao;

    public void setPersonDao(IPersonDao personDao) {
        this.personDao = personDao;
    }

    public void processSave() {
        System.out.println("-------------from PersonService.processSave()");

        personDao.save();
    }

}

四，dao

package com.deppon.test04.dao;
public interface IPersonDao {

    public void save();

}

package com.deppon.test04.dao.impl;

import com.deppon.test04.dao.IPersonDao;

public class PersonDao implements IPersonDao {

    public void save() {
        System.out.println("------------from PersonDao.save()");
    }

}

五，测试类

package com.deppon.test04.service;

import org.junit.Before;
import org.junit.Test;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class PersonServiceTest {
    private BeanFactory factory = null;

    @Before
    public void before() {
        factory = new ClassPathXmlApplicationContext("applicationContext.xml");
    }

    @Test
    public void testSpring() {
        IPersonService personService = (IPersonService) factory.getBean("personService");
        personService.processSave();
    }
}
