1.编写javabean，MailInfo.class

package com.xxx.javabean;


public class MailInfo {
    //邮箱服务器 如smtp.263.net
    private String host ;
    //用户邮箱 如**@xxx.com
    private String formName ;
    //用户授权码 不是用户名密码 可以自行查看相关邮件服务器怎么查看
    private String formPassword ;
    //消息回复邮箱
    private String replayAddress ;
    //发送地址
    private String toAddress ;
    //发送主题
    private String subject ;
    //发送内容
    private String content ;

    public String getHost() {
        return host;
    }
    public void setHost(String host) {
        this.host = host;
    }
    public String getFormName() {
        return formName;
    }
    public void setFormName(String formName) {
        this.formName = formName;
    }
    public String getFormPassword() {
        return formPassword;
    }
    public void setFormPassword(String formPassword) {
        this.formPassword = formPassword;
    }
    public String getReplayAddress() {
        return replayAddress;
    }
    public void setReplayAddress(String replayAddress) {
        this.replayAddress = replayAddress;
    }
    public String getToAddress() {
        return toAddress;
    }
    public void setToAddress(String toAddress) {
        this.toAddress = toAddress;
    }
    
    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;
    }
}

2.配置邮件的发送发和接收方的信息

package com.xxx.servlet;

import java.util.Date;
import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMultipart;



import com.xxx.javabean.MailInfo;
public class SendJavaHtmlEmail {
    //定义发送邮件用户的邮箱信息
    private final static String host="邮箱host";
    private final static String formName="邮箱账号，如xxx@xx.com";
    private final static String password="邮箱密码";
    private final static String replayAddress="邮箱账号，如xxx@xx.com";

    public static void sendHtmlMail(MailInfo info)throws Exception{
        info.setHost(host);
        info.setFormName(formName);
        info.setFormPassword(password);   //授权码~不一定是密码
        info.setReplayAddress(replayAddress);

        Message message = getMessage(info);
        // MiniMultipart类是一个容器类，包含MimeBodyPart类型的对象
        Multipart mainPart = new MimeMultipart();
        // 创建一个包含HTML内容的MimeBodyPart
        BodyPart html = new MimeBodyPart();
        // 设置HTML内容
        html.setContent(info.getContent(), "text/html; charset=utf-8");
        mainPart.addBodyPart(html);
        // 将MiniMultipart对象设置为邮件内容
        message.setContent(mainPart);
        Transport.send(message);
    }
    private static Message getMessage(MailInfo info) throws Exception{
        final Properties p = System.getProperties() ;
        p.setProperty("mail.smtp.host", info.getHost());
        p.setProperty("mail.smtp.auth", "true");
        p.setProperty("mail.smtp.user", info.getFormName());
        p.setProperty("mail.smtp.pass", info.getFormPassword());
        p.setProperty("mail.smtp.port", "465");
        p.setProperty("mail.smtp.socketFactory.port", "465");

        // 根据邮件会话属性和密码验证器构造一个发送邮件的session
        Session session = Session.getInstance(p, new Authenticator(){
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(p.getProperty("mail.smtp.user"),p.getProperty("mail.smtp.pass"));
            }
        });
        //session.setDebug(true);
        Message message = new MimeMessage(session);
        //消息发送的主题
        message.setSubject(info.getSubject());
        //接受消息的人
        message.setReplyTo(InternetAddress.parse(info.getReplayAddress()));
        //消息的发送者
        message.setFrom(new InternetAddress(p.getProperty("mail.smtp.user"),"发件者信息，如姓名"));
        // 创建邮件的接收者地址，并设置到邮件消息中
        message.setRecipients(Message.RecipientType.TO,new InternetAddress().parse(info.getToAddress()));

        // 消息发送的时间
        message.setSentDate(new Date());
        return message ;
    }
}

3.发送结果至相关用户邮箱

//配置发送邮件
    public  void send(String failName,String lineName,JSONObject jsonObject,Map mailMap) throws Exception{
        //System.out.println("发送邮件");  
        //邮件标题
        String title ="【"+lineName+"监控报警触发】发生接口异常报警";
        //遍历数组打印结果
        String content ="<table border=\"1\" cellspacing=\"0\" cellpadding=\"0\">";
        content+="<tr><td>所属服务</td>";
        content+="<td>用例名称</td>";
        content+="<td>运行结果</td>";

        content+="<td>错误描述</td></tr>";
        int contentCountLine=0,contentCountTester=0;
        String contentLine=content,contentTester=content;
        for(int i=0;i<jsonObject.getJSONArray("data").size();i++) {
            int caseFailCount = Integer.parseInt((String) jsonObject.getJSONArray("data").getJSONObject(i).get("caseFailCount"));

4.其他方法汇总

// 解析csv文件
    private ArrayList<String[]> read(String filepath) {
        ArrayList<String[]> csvList = new ArrayList<String[]>();
        try {
            File file = new File(filepath);

        } catch (IOException e) {
            e.printStackTrace();
        }
        return csvList;
    }

    // 读取当前系统日期
    public String refFormatNowDate(long timeMill) {
        Date nowTime = new Date(timeMill);
        SimpleDateFormat sdFormatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String retStrFormatNowDate = sdFormatter.format(nowTime);
        return retStrFormatNowDate;
    }

    // 获取当日时间戳
    public String formatTodayDate() {
        Date nowTime = new Date(System.currentTimeMillis());
        SimpleDateFormat tdFormatter = new SimpleDateFormat("yyyyMMdd");
        String formatStrTodayDate = tdFormatter.format(nowTime);
        return formatStrTodayDate;
    }
