SSH框架之spring整合javamail实现邮件服务

    邮件服务，一直是J2EE框架的一个很重要的功能组件。那么如何进行搭建这个邮件服务的组件呢，特别是你使用了spring框架的时候，如何搭建邮件服务？这是我在下面要进行说明的。
    使用spring搭建邮件服务，首先你需要对spring有一定的了解。这里，我不多说了

你找到spring的配置文件applicationContext.xml,在里面添加如下代码：

<import resource="classpath*:spring/**/*.xml" />

import进去的资源地址，是spring文件夹下面的所有以.xml结尾的文件
目录结构，你可以参考这个



下面，我们在resource/spring文件夹下面新建一个名称为：spring-mail.xml的配置文件，在里面添加如下代码

<bean id="mimeMessage" class="javax.mail.internet.MimeMessage" factory-bean="javaMailSender"  
	    factory-method="createMimeMessage" /> 


	<bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">   
	    <property name="host" value="smtp.sina.com" />  
	    <property name="username" value="[email protected]" />   
	    <property name="password" value="yourpassword" />   
	    <property name="javaMailProperties">   
	        <props>   
	            <prop key="mail.smtp.auth">true</prop>   
	            <prop key="mail.smtp.host">smtp.sina.com</prop>
	            <prop key="mail.smtp.timeout">25000</prop>   
	            <!-- <prop key="mail.smtp.port">25</prop>   
	            <prop key="mail.smtp.socketFactory.port">25</prop>   
	            <prop key="mail.smtp.socketFactory.fallback">false</prop>   
	            <prop key="mail.smtp.socketFactory.class">javax.net.ssl.SSLSocketFactory</prop>
	            -->   
	        </props>   
	    </property>   
	</bean>  

	<bean id="mailService" class="com.core.base.mail.service.impl.MailServiceImpl">
		<property name="mailSender" ref="javaMailSender" /> 
		<property name="mimeMessage" ref="mimeMessage" /> 
	</bean>  

注意，我使用的是新浪的邮箱，如果你不是使用新浪邮箱，请修改host的value

这个时候，spring的配置文件就写好了，接下来，我们看看具体的java代码如何实现吧

第一个java类：MailModel

package com.core.base.mail.model;

/**
 * 邮件model
 * @author Administrator
 *
 */
public class MailModel {
	private String fromAddress;//发送人地址1个
	private String toAddresses;//接收人地址,可以为很多个，每个地址之间用";"分隔，比方说[email protected];[email protected]
	private String subject;//邮件主题
	private String content;//邮件文本内容
	private String[] attachFileNames;//附件 
	public String getFromAddress() {
		return fromAddress;
	}
	public void setFromAddress(String fromAddress) {
		this.fromAddress = fromAddress;
	}
	public String getToAddresses() {
		return toAddresses;
	}
	public void setToAddresses(String toAddresses) {
		this.toAddresses = toAddresses;
	}
	public String getSubject() {
		return subject;
	}
	public void setSubject(String subject) {
		this.subject = subject;
	}
	public String getContent() {
		return content;
	}
	public void setContent(String content) {
		this.content = content;
	}
	 
	public void setAttachFileNames(String[] attachFileNames) {
		this.attachFileNames = attachFileNames;
	}
	public String[] getAttachFileNames() {
		return attachFileNames;
	}
	
}

   【这个类是邮件的model，包含了发送邮件的一些需要的属性】

第二个类：MailServiceImpl，这个类是继承的MailService接口。具体的模式我是跟ssh框架开发差不多的结构

package com.core.base.mail.service.impl;

import java.io.File;
import java.util.Date;
import java.util.Properties;

import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.mail.Address;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

import org.apache.log4j.Logger;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;

import com.core.base.mail.model.MailModel;
import com.core.base.mail.model.MailSenderInfo;
import com.core.base.mail.service.MailService;
import com.core.base.util.mail.MyAuthenticator;

public class MailServiceImpl implements MailService {

	private JavaMailSender mailSender;
	private MimeMessage mimeMessage;
	private static Logger logger = Logger.getLogger(MailServiceImpl.class);

	/**
	 * 发送html格式的，带附件的邮件
	 */
	@Override
	public void sendAttachMail(MailModel mail) {

		try {
			MimeMessageHelper mailMessage = new MimeMessageHelper(
					this.mimeMessage, true, "UTF-8");
			mailMessage.setFrom(mail.getFromAddress());// 设置邮件消息的发送者

			mailMessage.setSubject(mail.getSubject());// 设置邮件消息的主题
			mailMessage.setSentDate(new Date());// 设置邮件消息发送的时间
			mailMessage.setText(mail.getContent(), true); // 设置邮件正文，true表示以html的格式发送

			String[] toAddresses = mail.getToAddresses().split(";");// 得到要发送的地址数组
			for (int i = 0; i < toAddresses.length; i++) {
				mailMessage.setTo(toAddresses[i]);
				for (String fileName : mail.getAttachFileNames()) {
					mailMessage.addAttachment(fileName, new File(fileName));
				}
				// 发送邮件
				this.mailSender.send(this.mimeMessage);
				logger.info("send mail ok=" + toAddresses[i]);
			}
			 

		} catch (Exception e) {
			logger.error(e);
			e.printStackTrace();
		}

	}
}

通过这个servieimpl，可以实现发现邮件

最后，我们来进行一个测试，这里还要进行一个说明，项目采用的是SSH框架
为了方便，我也不考虑那么多了，当用户进行登录系统的时候，给他发一封邮件通知他。
    a.在UserAction里面，注入mailService。

package com.neweducation.user.action;

import com.core.base.action.BaseAction;
import com.core.base.mail.model.MailModel;
import com.core.base.mail.service.impl.MailServiceImpl;
import com.neweducation.user.model.UserModel;
import com.neweducation.user.service.UserService;
import com.opensymphony.xwork2.ModelDriven;

public class UserAction extends BaseAction implements ModelDriven<UserModel> {

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private UserService userService;

	private UserModel userModel = new UserModel();
	private MailServiceImpl mailService;

	/**
	 * 登录
	 * 
	 * @return
	 */
	public String userLogin() {
		UserModel user = userService.loginJudge(userModel.getUserName(),
				userModel.getUserPass());
		if (user != null) {			 
			MailModel mm = new MailModel();
			String fileNames[] = { "e:/xx.txt" };
			mm.setAttachFileNames(fileNames);
			mm.setFromAddress("[email protected]");
			mm.setToAddresses("[email protected];[email protected]");
			mm.setContent("在做项目的过程中，我们经常会遇到这样的情况，需要进行单点登录<br/>，也就是说用户登录一个系统的同时也登录到其他系统。<br/> ");
			mm.setSubject("这是一个spring整合javamail的测试");
			mailService.sendAttachMail(mm);
			return SUCCESS;
		} else {
			return INPUT;
		}
	}

	public void setUserService(UserService userService) {
		this.userService = userService;
	}

	public UserService getUserService() {
		return userService;
	}

	@Override
	public UserModel getModel() {
		return getUserModel();
	}

	public void setUserModel(UserModel userModel) {
		this.userModel = userModel;
	}

	public UserModel getUserModel() {
		return userModel;
	}

	public void setMailService(MailServiceImpl mailService) {
		this.mailService = mailService;
	}

	public MailServiceImpl getMailService() {
		return mailService;
	}

}

b.修改spring-bean-user.xml配置文件的内容，以实现mailService的注入

<?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"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
            http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd"
	default-lazy-init="true" default-autowire="byName">


	<bean id="UserAction" class="com.neweducation.user.action.UserAction"
		scope="prototype">
		<property name="userService" ref="userService" />
		<property name="mailService" ref="mailService" />
	</bean>

	<bean id="userService" class="com.neweducation.user.service.impl.UserServiceImpl">
		<property name="userDao" ref="userDao" />		
	</bean>

	<bean id="userDao" class="com.neweducation.user.dao.UserDao">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>

	 

</beans>

自己写一个login。jsp，实现登录就可以了
