Maven学习（七）- 构建Spring项目

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...


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

[html] view
plaincopy

<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>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

</dependency>

<dependency>

<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

[html] view
plaincopy

<?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

[java] view
plaincopy

package com.deppon.test04.dao;

public interface IPersonDao {

public void save();

}

PersonDao.java

[java] view
plaincopy

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

[java] view
plaincopy

package com.deppon.test04.service;

public interface IPersonService {

public void processSave();

}

PersonService.java

[java] view
plaincopy

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

[java] view
plaincopy

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！)

1. mvn compile

2.mvn test-compile

运行结果：
