初学Maven小例子--使用greenmail测试邮件

利用Maven构建的一个小工程，闲话少叙，直入正题：
1、利用mvn archetype:generate生成基本的项目骨架
2、修改pom.xml:

<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>com.maven.account</groupId>
  <artifactId>account-email</artifactId>
  <version>1.0-SNAPSHOT</version>
  <name>Account Email</name>
  <packaging>jar</packaging>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	<springframework.version>2.5.6</springframework.version>
  </properties>

  <dependencies>
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-core</artifactId>
		<version>${springframework.version}</version>
	</dependency>
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-beans</artifactId>
		<version>${springframework.version}</version>
	</dependency>
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-context</artifactId>
		<version>${springframework.version}</version>
	</dependency>
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-context-support</artifactId>
		<version>${springframework.version}</version>
	</dependency>
	<dependency>
		<groupId>javax.mail</groupId>
		<artifactId>mail</artifactId>
		<version>1.4.1</version>
	</dependency>
	<dependency>
		<groupId>com.icegreen</groupId>
		<artifactId>greenmail</artifactId>
		<version>1.3.1b</version>
		<scope>test</scope>
	</dependency>

    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.7</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
</project>

3、写接口AccountEmailService.java

package com.maven.account;

/**
 * @Author:liuxb
 * @Date: 2012-08-04
 */
public interface AccountEmailService 
{
    void sendMail(String to,String subject,String htmlText) throws Exception;
}

4、写实现类AccountEmailServiceImpl.java

package com.maven.account;

/**
 * @Author:liuxb
 * @Date: 2012-08-04
 */

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;

public class AccountEmailServiceImpl implements AccountEmailService
{
	private JavaMailSender javaMailSender;

	private String systemEmail;
	
	public void sendMail(String to,String subject,String htmlText) throws Exception{
		try{
			MimeMessage msg = javaMailSender.createMimeMessage();
			MimeMessageHelper msgHelper = new MimeMessageHelper(msg);

			msgHelper.setFrom(systemEmail);
			msgHelper.setTo(to);
			msgHelper.setSubject(subject);
			msgHelper.setText(htmlText,true);

			javaMailSender.send(msg);
		}catch(MessagingException e){
			e.printStackTrace();
		}
	}

	public JavaMailSender getJavaMailSender(){
		return javaMailSender;
	}

	public void setJavaMailSender(JavaMailSender javaMailSender){
		this.javaMailSender = javaMailSender;
	}
	
	public String getSystemEmail(){
		return systemEmail;
	}

	public void setSystemEmail(String systemEmail)
	{
		this.systemEmail = systemEmail;
	}
}

5、在src目录下新建文件夹resources
6、在resources目录下建立spring配置文件account-email.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"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

	<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="location" value="classpath:service.properties" />
	</bean>

	<bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
		<property name="protocol" value="${email.protocol}" />
		<property name="host" value="${email.host}" />
		<property name="port" value="${email.port}" />
		<property name="username" value="${email.username}" />
		<property name="password" value="${email.password}"/>
		<property name="javaMailProperties">
			<props>
				<prop key="mail.${email.protocol}.auth">${email.auth}</prop>
			</props>
		</property>
	</bean>

	<bean id="accountEmailService" class="com.maven.account.AccountEmailServiceImpl">
		<property name="javaMailSender" ref="javaMailSender" />
		<property name="systemEmail" value="${email.systemEmail}" />
	</bean>

</beans>

7、在resources目录下建立service.properties文件

email.protocol=smtp
email.host=localhost
email.port=25
[email protected]
email.password=123456
email.auth=true
[email protected]

8、建立测试类AccountEmailServiceTest.java

package com.maven.account;

import static junit.framework.Assert.assertEquals;

import javax.mail.Message;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.icegreen.greenmail.util.GreenMail;
import com.icegreen.greenmail.util.GreenMailUtil;
import com.icegreen.greenmail.util.ServerSetup;

//import junit.framework.Test;
//import junit.framework.TestCase;
//import junit.framework.TestSuite;

/**
 * Unit test for simple App.
 */
public class AccountEmailServiceTest 
{
	private GreenMail greenMail;

	@Before
	public void startMailServer() throws Exception{
		greenMail = new GreenMail(ServerSetup.SMTP);
		greenMail.setUser("[email protected]","123456");
		greenMail.start();
	}

	@Test
	public void testSendMail() throws Exception{
		ApplicationContext ctx = new ClassPathXmlApplicationContext("account-email.xml");
		AccountEmailService accountEmailService = (AccountEmailService)ctx.getBean("accountEmailService");

		String subject = "Test Subject";
		String htmlText = "<h3>Test</h3>";
		accountEmailService.sendMail("[email protected]",subject,htmlText);

		greenMail.waitForIncomingEmail(2000,1);

		Message[] msgs = greenMail.getReceivedMessages();
		System.out.println("msgs.length="+msgs.length);
		System.out.println("subject="+msgs[0].getSubject());
		System.out.println("htmlText="+GreenMailUtil.getBody(msgs[0]).trim());

		assertEquals(1,msgs.length);
		assertEquals(subject,msgs[0].getSubject());
		assertEquals(htmlText,GreenMailUtil.getBody(msgs[0]).trim());
	}

	@After
	public void stopMailServer() throws Exception{
		greenMail.stop();
	}
}

9、在项目根目录下使用命令mvn clean test进行测试。
输出如下：




10、使用命令mvn dependency:tree查看依赖树：
