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 masque.java@gmail.com
*
*/
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 masque.java@gmail.com
*
*/
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("test_for_masque@sina.cn",
"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 masque.java@gmail.com
*
*/
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 = test_for_masque@sina.cn
user.password = test_for_masque

邮件的主题和内容实体封装

/**
*
* @author masque.java@gmail.com
*
*/
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:

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("XXXXX@qq.com");
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();
}
}
}
