利用java api 創建excel 內容并發送郵件

主要實現功能:

1.通過配置文件設置發送郵件發送方，接收方，抄送方

2.目前實現了 自定義發送內容

3.實現了excel 郵件發送內容

核心代碼 (SendMailManager ) :

package com.javatool.email.proxy;

import com.javatool.configer.DefaultConfigerContext;

import com.javatool.email.model.MailAuthenticator;

import com.javatool.email.model.SendMailConfigModel;

import javax.mail.*;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeBodyPart;

import javax.mail.internet.MimeMessage;

import javax.mail.internet.MimeMultipart;

import java.util.Date;

import java.util.List;

import java.util.Properties;
