Maven account-email例子

1.在Eclipse中新建Maven工程。

2.修改POM文件内容为：

<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.iteye.xujava</groupId>
  <artifactId>account-email</artifactId>
  <version>1.0.0</version>
  <packaging>jar</packaging>

  <name>account-email</name>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
  	<dependency>
  		<groupId>org.springframework</groupId>
  		<artifactId>spring-core</artifactId>
  		<version>2.5.6</version>
  	</dependency>
  	<dependency>
  		<groupId>org.springframework</groupId>
  		<artifactId>spring-beans</artifactId>
  		<version>2.5.6</version>
  	</dependency>
  	<dependency>
  		<groupId>org.springframework</groupId>
  		<artifactId>spring-context</artifactId>
  		<version>2.5.6</version>
  	</dependency>
  	<dependency>
  		<groupId>org.springframework</groupId>
  		<artifactId>spring-context-support</artifactId>
  		<version>2.5.6</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>4.9</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
</project>

2.在src/main/java的包com.iteye.xujava.account.email下新建三个文件AccountEmailException、AccountEmailService、AccountEmailServiceImpl

package com.iteye.xujava.account.email;

public class AccountEmailException extends Exception {

	private static final long serialVersionUID = 6514881539290222459L;

	public AccountEmailException(String message) {
		super(message);
	}

	public AccountEmailException(String message, Throwable throwable) {
		super(message, throwable);
	}

}

package com.iteye.xujava.account.email;

public interface AccountEmailService {

	void sendMail(String to,String subject,String htmlText) throws AccountEmailException;
}

package com.iteye.xujava.account.email;

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 AccountEmailException {
		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);
			System.out.println("发送完毕");
		} catch (MessagingException e) {
			throw new AccountEmailException("发送邮件失败...", e);
		}
	}

	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;
	}

}

3.在src/main/resources目录下新建account-email.xml和service.properties文件

<?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-2.5.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.iteye.xujava.account.email.AccountEmailServiceImpl">
		<property name="javaMailSender" ref="javaMailSender" />
		<property name="systemEmail" value="${email.systemEmail}" />
	</bean>
</beans>

#真实
#email.protocol=smtp
#email.host=smtp.163.com
#email.port=25
#[email protected]
#email.password=password
#email.auth=true
#[email protected]

#测试
email.protocol=smtp
email.host=127.0.0.1
email.port=25
[email protected]
email.password=123456
email.auth=true
[email protected]

4.在src/test/java的包 com.iteye.xujava.account.email下新建测试文件

package com.iteye.xujava.account.email;

import static org.junit.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;

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 = "Text Subject";
		String htmlText = "<h3>Test</h3>";

		accountEmailService.sendMail("[email protected]", subject, htmlText);

		greenMail.waitForIncomingEmail(2000, 1);

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

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

5.在命令提示行找到account-email目录，输入mvn clean test测试，成功后，输入mvn clean install安装到Maven库。
