循序渐进之Maven(2) - 第一个Maven项目

如果还没有搭建好Maven环境，请参考上一节内容

http://blog.youkuaiyun.com/autfish/article/details/51008788

1 打开Eclipse，File -> New -> Maven Project

直接勾选 Create a simple project

Group Id是项目组织代码，这里填写包名demo.maven; Artifact Id填写项目名称。其他忽略 -> Finish

新建的项目目录结构如下图：

2 修改pom.xml，添加dependency

这里添加了junit和spring用于演示

<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/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>demo.maven</groupId>
	<artifactId>maven-demo</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<dependencies>
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>4.8.1</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-context</artifactId>
			<version>3.1.1.RELEASE</version>
		</dependency>
	</dependencies>
</project>

3 添加Pet类

在源码目录 src/main/java下新建Package: demo.maven

新建类Pet

package demo.maven;

public class Pet {

	private String name;

	public String getName() {
		return name;
	}

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

4 添加applicationContext.xml

在src/main/resources下新建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:p="http://www.springframework.org/schema/p"
	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/context
  http://www.springframework.org/schema/context/spring-context-3.0.xsd">

	<bean id="pet" class="demo.maven.Pet">
		<property name="name" value="Tom"></property>
	</bean>
</beans>

5 添加测试类

在 src/test/java下新建 testcase.TestPet.java

package testcase;

import junit.framework.TestCase;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import demo.maven.Pet;

public class PetTest extends TestCase {

	public void testPet() {
		ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
		Pet pet = context.getBean("pet", Pet.class);
		System.out.println(pet.getName());
		assertTrue(true);
	}

}

6 运行

完成上述步骤后，目录结构如下：

在PetTest.java上右键 -> Run as -> JUnit test
