javamail開發郵件【發送郵件】

用到java開發發送郵件的部分，其實很簡單依賴的jar包有點擊下載(無需積分)

主要是郵箱的服務器的驗證

以下是源碼

都是經過我自己運行才發表的,有任何問題可以留言或者郵箱聯繫我,我會第一時間處理。

 

服務器登陸的安全認證:

 

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

/**
 * 服務器郵箱登錄驗證
 * 
 * @author [email protected]
 * 
 */
public class MailAuthenticator extends Authenticator {

	/**
	 * 用戶名（登錄郵箱）
	 */
	private String username;
	/**
	 * 密碼
	 */
	private String password;

	/**
	 * 初始化郵箱和密碼
	 * 
	 * @param username
	 *            郵箱
	 * @param password
	 *            密碼
	 */
	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;
	}

}

發件箱工廠:

 

 

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

/**
 * 發件箱工廠
 * 
 * @author [email protected]
 * 
 */
public class MailSenderFactory {

	/**
	 * 服務郵箱
	 */
	private static SimpleMailSender serviceSms = null;

	/**
	 * 獲取郵箱
	 * 
	 * @param type
	 *            郵箱類型
	 * @return 符合類型的郵箱
	 * @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;
	}
}

發送郵件用戶名以及密碼我是在文件中配置的

 

 

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

/**
 * 讀取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;
	}

}

配置用戶名以及密碼:mail-user.properties

 

 

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

郵件的主題和內容實體封裝

 

 

/**
 * 
 * @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;
	}

}

import javax.mail.Message.RecipientType;

運行測試主方法:將地址改爲自己的QQ郵箱測試下吧
