2.AccountEmailService.java接口

package com.newtouch.mvnbook.account.email;

public interface AccountEmailService {
	/**sendMail()方法用来发送html格式的邮件，to为接收地址，subject为邮箱主题，htmlText为邮箱内容，
	 * 如果发送邮箱出错，则抛出AccountEmailException异常。
	 * 
	 * @param to
	 * @param subject
	 * @param htmlText
	 * @throws AccountEmailException
	 */
	public void sendMail(String to, String subject, String htmlText) throws AccountEmailException;

}

 

3.接口的实现AccountEmailServiceImpl

package com.newtouch.mvnbook.account.email;

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

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

public class AccountEmailServiceImpl implements AccountEmailService{

	private JavaMailSender javaMailSender;
	
	private String systemEmail;
	
	@Override
	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);//true表示邮箱的内容为html格式
				javaMailSender.send(msg);
			} catch (MessagingException e) {
				throw new AccountEmailException("Fail to send email.", 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;
	}

}

 

4.自定义异常AccountEmailException

package com.newtouch.mvnbook.account.email;

public class AccountEmailException extends Exception {
	
	public AccountEmailException(String msg, Throwable cause) {

		super(msg, cause);

	}
}

 

5.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> 

 

6.属性文件service.properties

email.protocol=smtp
#使用localhost不一定可以，换成127.0.0.1
#email.host=localhost  
email.host=127.0.0.1
email.port=25  
email.username=[e-mail]  
email.password=123456  
email.auth=true  
email.systemEmail=[e-mail]  

 

7.编写测试类AccountEmailServiceTest

package com.newtouch.mvnbook.account.email;

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("[e-mail]","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>gaoweigang</h3>";  
        accountEmailService.sendMail("[e-mail]",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();  
    }  
}
