（七）- 构建Spring项目-Maven学习之旅

在这里，使用Maven构建一个Spring项目，正在做练习，下午有事，可能要晚上回来接着写... 快哭了

构建单独项目的话，其实都差不多

1. 新建一个Web项目

参考之前的博客

2.修改 pom.xml，添加Spring依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.deppon.demo</groupId>
  <artifactId>test04</artifactId>
  <packaging>war</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>test04 Maven Webapp</name>
  <url>http://maven.apache.org</url>
  
   <!-- 属性配置 -->
  <properties>
      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>
  
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.10</version>
      <scope>test</scope>
    </dependency>
    
    <!-- 添加Spring依赖 -->
    <dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-core</artifactId>
		<version>3.1.1.RELEASE</version>
	</dependency>
	
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-beans</artifactId>
		<version>3.1.1.RELEASE</version>
	</dependency>
	
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-context</artifactId>
		<version>3.1.1.RELEASE</version>
	</dependency>
    
    <dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-jdbc</artifactId>
		<version>3.1.1.RELEASE</version>
	</dependency>
	
  </dependencies>
  <build>
    <finalName>test04</finalName>
  </build>
</project>

3.添加Spring配置文件，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>

IPersonDao.java

package com.deppon.test04.dao;

public interface IPersonDao {
	
	public void save();
	
}

PersonDao.java

package com.deppon.test04.dao.impl;

import com.deppon.test04.dao.IPersonDao;

public class PersonDao implements IPersonDao {

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

}

IPersonService.java

package com.deppon.test04.service;

public interface IPersonService {
	
	public void processSave();
}

PersonService.java

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;
	}

	@Override
	public void processSave() {
		System.out.println("-------------from PersonService.processSave()");
		
		personDao.save();
	}

}

测试类：PersonServiceTest.java

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();
	}
}

项目结构如下图所示：

注意：

在运行测试程序之前，还需要运行两个命令：(ps:可能出现找不到applicationContext.xml的错误！)

mvn compile

2.mvn test-compile

运行结果：
