准备工作
1、Java架包（javax.mail-1.5.0.jar）
2、搭建Java工程
Java工程
3、对应图片创建文件目录
com.ding.test---测试类
com.ding.tools---邮件类
mail.properties---邮件配置类
开始代码
1、先看看要写哪些类
邮件发送类
2、代码走起

mail.properties邮件配置
##邮件发送服务器
mail.mailHost=smtp.sina.com
##邮件发送服务器端口号
mail.mailPort=25
##邮件用户名
mail.userName=newsisyphus
##密码
mail.pwd=youjianmima
##邮件的地址（用于发送邮件）
mail.fromAddr=newsisyphus@sina.com
注意：##
1、有些代理发送的，要到邮箱中设置开启代理发件服务
2、对应的端口号，地址，用户名，请参考网上配置
Test.java
package com.ding.test;
import java.util.ArrayList;
import java.util.List;
import com.ding.tools.MailSend;
public class Test {
public static void main(String[] args) {
String email = "shoujianren@sss.com";//收件邮箱
List<String> emails = new ArrayList();
emails.add(email);
MailSend tMail = new MailSend();
String mailinfo = "<h1>test</h1>test<p>test</p><a href=\"#\">test</a>";//邮件内容
String mailItem = "邮件主题";//邮件主题
boolean sendflag = tMail.ExecuteMailSends(mailItem , mailinfo, emails);//发送邮件
if (sendflag) {//判断是否成功
System.out.println("success!!");
}
}
}
tMail.ExecuteMailSends(mailItem , mailinfo, emails);可以配置多个邮件
tMail.ExecuteMailSend方法发送单个邮件
对于邮件发送还有什么问题，可以联系我qq:461874689
