前言

本文通过htmlmail实现发送html样式表格，html可设计任意样式，但有一定区别，这里设计一个excel表格并带附件和图片

话不多说，直接上代码

一、准备工作

这里需要导包，给出包名，可自己去查找对照添加就好

import com.iss.iescp.webfwk.context.PlatformContext;import com.taiping.claimcore.vo.MailVO;import mons.mail.EmailException;import mons.mail.HtmlEmail;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import javax.mail.*;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;import java.io.File;import java.util.Objects;import java.util.Properties;

二.设计一个MailUtil类

代码如下（示例）：

public class MailUtil {private final static Logger logger = LoggerFactory.getLogger(ExcelUtil.class);public static boolean send(MailVO mail) {// 发送emailHtmlEmail email = new HtmlEmail();try {// 这里是SMTP发送服务器的名字：163的如下：""email.setHostName(mail.getHost());// 字符编码集的设置email.setCharset(MailVO.ENCODEING);// 收件人的邮箱email.addTo(mail.getReceiver());// 发送人的邮箱email.setFrom(mail.getSender(), mail.getName());// 如果需要认证信息的话，设置认证：用户名-密码。分别为发件人在邮件服务器上的注册名称和密码email.setAuthentication(mail.getUsername(), mail.getPassword());// 要发送的邮件主题email.setSubject(mail.getSubject());// 要发送的信息，由于使用了HtmlEmail，可以在邮件内容中使用HTML标签email.setHtmlMsg(mail.getHtml());// 要发送的附件if (mail.getFile() != null) {email.embed(mail.getFile());}//加入图片File file = new File(mail.getImg());email.embed(file, "image");//给出cid// 发送email.send();if (logger.isDebugEnabled()) {logger.debug(mail.getSender() + " 发送邮件到 " + mail.getReceiver());}return true;} catch (EmailException e) {e.printStackTrace();logger.info(mail.getSender() + " 发送邮件到 " + mail.getReceiver() + " 失败");return false;}}

注意！！！！：这里的图片，使用html不能直接用src=“”加入，需要导入附件以后，给出一个cid标识，再将图片加入正文（当时踩了很多坑）

三.实现类

代码如下（示例）：

package com.taiping.claimcore.Email.service;/*** @author TuGiant* @param* @return* @throws* @date*/import com.iss.iescp.devfwk.exception.ServiceException;import com.taiping.claimcore.Email.Vo.EmailVo;import com.taiping.claimcore.util.MailUtil;import com.taiping.claimcore.vo.MailVO;import java.beans.PropertyDescriptor;import java.io.File;import java.lang.reflect.Field;import java.lang.reflect.Method;import java.math.BigDecimal;import java.util.Arrays;import java.util.List;/*** @program: * @description:* @author: TuGiant* @create: -07-14 09:51**/public class SendEmailService {public void email(List<EmailVo> emaillist) throws ServiceException {try {//映射字段判空for (int i = 0; i < emaillist.size(); i++) {EmailVo emailVo = emaillist.get(i);Class<?> clazz = emailVo.getClass();Field[] declaredFields = clazz.getDeclaredFields();Arrays.asList(declaredFields).stream().forEach(field -> {try {String filedName = field.getName();PropertyDescriptor pd = new PropertyDescriptor(filedName, clazz);Method readMethod = pd.getReadMethod();Object value = readMethod.invoke(emailVo);if (value == null) {Method writeMethod = pd.getWriteMethod();writeMethod.invoke(emailVo, "");}} catch (Exception e) {e.printStackTrace();}});}MailVO mailVO = new MailVO();mailVO.setHost("");//SMTP发送服务器的名字（这里用的网易企业邮箱）mailVO.setSender("××××××@×××.com");//发件人mailVO.setName("××××××@×××.com");//发件人昵称mailVO.setUsername("××××××@×××.com");//账号mailVO.setPassword("×××××××××××××××");//授权密码（在邮箱里获取）mailVO.setSubject("测试");//主题mailVO.setReceiver(emaillist.get(0).getReceiver());String excelhtml = excelhtml(emaillist);//生成表格mailVO.setHtml(excelhtml);//添加表格htmlString img = this.getClass().getClassLoader().getResource("/file/嘻嘻.jpg").getPath();//加入图片if ("".equals(emaillist.get(0).getReceiver())) {throw new ServiceException("发送失败, 收件人为空");}if ("".equals(emaillist.get(0).getExcelPath())) {throw new ServiceException("发送失败,附件地址为空");}mailVO.setFile(new File(emaillist.get(0).getExcelPath()));//添加附件地址mailVO.setImg(img);if ("".equals(emaillist.get(0).getCBtachType()) || emaillist.get(0).getCBtachType() == null) {throw new ServiceException("发送失败, 性质为空");}MailUtil.send(mailVO);//发送} catch (Exception e) {throw new ServiceException("发送失败", e);}}private String excelhtml(List<EmailVo> emaillist) {BigDecimal NPayNum = new BigDecimal("0.00");for(EmailVo emailVos : emaillist){BigDecimal b1 = new BigDecimal(emailVos.getNPayNum());NPayNum = NPayNum.add(b1);}//=============================网页1===============================String htmlpustart = "<!DOCTYPE html>\n" +"<html lang=\"zh\">\n" +"<head>\n" +" <title>demo</title>\n" +"<style

这里设计了两个表格，根据入参选择的表格，仅供参考
