javamail开发邮件【发送邮件】

用到java开发发送邮件的部分，其实很简单依赖的jar包有点击下载(无需积分)

主要是邮箱的服务器的验证

以下是源码

都是经过我自己运行才发表的,有任何问题可以留言或者邮箱联系我,我会第一时间处理。

 

服务器登陆的安全认证:

 

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

/**
 * 服务器邮箱登录验证
 * 
 * @author [email protected]
 * 
 */
public class MailAuthenticator extends Authenticator {

	/**
	 * 用户名（登录邮箱）
	 */
	private String username;
	/**
	 * 密码
	 */
	private String password;

	/**
	 * 初始化邮箱和密码
	 * 
	 * @param username
	 *            邮箱
	 * @param password
	 *            密码
	 */
	public MailAuthenticator(String username, String password) {
		this.username = username;
		this.password = password;
	}

	String getPassword() {
		return password;
	}

	@Override
	protected PasswordAuthentication getPasswordAuthentication() {
		return new PasswordAuthentication(username, password);
	}

	String getUsername() {
		return username;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public void setUsername(String username) {
		this.username = username;
	}

}

发件箱工厂:

 

 

import java.io.IOException;
import java.util.Properties;

/**
 * 发件箱工厂
 * 
 * @author [email protected]
 * 
 */
public class MailSenderFactory {

	/**
	 * 服务邮箱
	 */
	private static SimpleMailSender serviceSms = null;

	/**
	 * 获取邮箱
	 * 
	 * @param type
	 *            邮箱类型
	 * @return 符合类型的邮箱
	 * @throws IOException
	 */
	public static SimpleMailSender getSender() throws IOException {
		if (initUser() == null) {
			serviceSms = new SimpleMailSender("[email protected]",
					"test_for_masque");
		}
		return serviceSms;
	}

	private static SimpleMailSender initUser() throws IOException {
		Properties p = PropertiesUtil.getInstance("mail-user.properties");
		if (null == p)
			return null;
		serviceSms = new SimpleMailSender(p.getProperty("user.name"),
				p.getProperty("user.password"));
		return serviceSms;
	}
}

发送邮件用户名以及密码我是在文件中配置的

 

 

import java.io.IOException;
import java.util.Properties;

/**
 * 读取Properties
 * 
 * @author [email protected]
 * 
 */
public class PropertiesUtil {

	static Properties props = new Properties();

	private PropertiesUtil() {
	}

	public static Properties getInstance(String path) throws IOException {
		props.load(PropertiesUtil.class.getClassLoader().getResourceAsStream(
				path));
		return props;
	}

	public static String getProperty(String key) {
		String val = "";
		if (props != null) {
			String prop = props.getProperty(key);
			if (prop != null) {
				val = prop;
			}
		}
		return val;
	}

}

配置用户名以及密码:mail-user.properties

 

 

#test
user.name = [email protected]
user.password = test_for_masque

邮件的主题和内容实体封装

 

 

/**
 * 
 * @author [email protected]
 * 
 */
public class SimpleMail {

	private String subject;

	private String content;

	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;
	}

}

邮件发送的类:

import javax.mail.Message.RecipientType;
import javax.mail.MessagingException;

	public SimpleMailSender(final String username, final String password) {

运行测试主方法:将地址改为自己的QQ邮箱测试下吧

 

 

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import javax.mail.MessagingException;
import javax.mail.internet.AddressException;

 */
public class Main {
	public static void main(String[] args) {
		try {
			SimpleMailSender sender = MailSenderFactory.getSender();
			List<String> recipients = new ArrayList<String>();
			for(int i=0;i<10;i++)
			recipients.add("[email protected]");
			for (String recipient : recipients)
				sender.send(recipient, "测试邮件", "这是一封测试邮件！");
			// sender.send(recipients, subject, content);
		} catch (IOException e) {
			e.printStackTrace();
		} catch (AddressException e) {
			e.printStackTrace();
		} catch (MessagingException e) {
			e.printStackTrace();
		}
	}
}
