Spring mvc +ajax 发送邮件

1.前端页面--form表单提交，通过发送按钮的id=“send”定位DOM，触发ajax请求

                <form class="form-horizontal" id="emailEdit" style="display: none;margin: 40px;">

                    <%--收件人--%>

                    <div class="form-group">

                        <label for="emailer" class="col-sm-2 control-label" >收件人</label>

                        <div class="col-sm-10" style="width: 82%" >

                            <textarea class="form-control" rows="3" name="emailer" id="emailer" placeholder="多个收件人，请以,隔开"></textarea>

                        </div>

                    </div>

                    <%--邮件标题--%>

                    <div class="form-group" >

                        <label for="taskName" class="col-sm-2 control-label">邮件标题</label>

                        <div class="col-sm-10" style="width: 82%" >

                            <input type="text" class="form-control" name="emailTitle" id="emailTitle" placeholder="邮件标题">

                        </div>

                    </div>

                    <%--正文--%>

                    <div class="form-group" >

                        <label for="accdescription" class="col-sm-2 control-label">正文</label>

                        <div class="col-sm-10" style="width: 82%" >

                            <textarea class="form-control" rows="10" name="emailContent" id="emailContent" placeholder="邮件正文"></textarea>

                        </div>

                    </div>

                    <div class="form-group" style="float: right;margin-right: 40px;margin-top: 30px">

                        <div class="col-sm-offset-2 col-sm-10" >

                            <button type="button" class="btn btn-success" id="send" style="background-color: #FF8C00" >发送</button>

                        </div>

                    </div>

                </form>

2.ajax请求

formCheckClean清除校验格式的函数

checkparam() 校验输入非空，以及邮箱格式是否正确的函数

　通过发送按钮的id--send的点击事件，触发ajax请求　

var index11;

        function formCheckClean(){

            $('.text-danger').remove();//首先清除提示的标签

            $("*").removeClass('has-error');//清除has-error错误样式

        }//校验样式清除函数

　　　　//邮箱非空校验及格式校验函数

        function checkparam(){

            var flag=true;

            var emailer=$("#emailer").val();

            var emailTitle=$("#emailTitle").val();

            if(emailer == null || emailer == ""){

                $("#emailer").parent().parent().addClass('form-group has-error');

                $("#emailer").parent().after('<label class="control-label text-danger"  style="display:block;float: right;color: red"><i class="fa fa-times-circle-o"></i> 必填项不能为空！</label>');

                flag=false;

            }else{

                reg = /^\w+((-\w+)|(\.\w+))*\@[A-Za-z0-9]+((\.|-)[A-Za-z0-9]+)*\.[A-Za-z0-9]+$/;

                var strList=emailer.split(",");

                var errorcount =0;

                var errormail ="";

                for(i=0;i<strList.length;i++){

                    if(!reg.test(strList[i])){

                        errormail=errormail+strList[i]+'；';

                        errorcount++;

                    }

                }

                if(errorcount >=1){

                    // console.log("不符合要求的邮箱个数："+errorcount);

                    $("#emailer").parent().parent().addClass('form-group has-error');

                    $("#emailer").parent().after('<label class="control-label text-danger" style="display:block;float: right;color: red"><i class="fa fa-times-circle-o"></i>'+'错误邮箱：'+errormail+'</label>');

                    flag=false;

                }

            }

            if(emailTitle == null || emailTitle == ""){

                $("#emailTitle").parent().parent().addClass('form-group has-error');

                $("#emailTitle").parent().after('<label class="control-label text-danger"   style="display:block;float: right;color: red"><i class="fa fa-times-circle-o"></i> 必填项不能为空！</label>');

                flag=false;

            }

           return flag;

        }

        //发送邮件函数

        $("button#send").unbind("click").click(function(){

            formCheckClean();

            var flag=checkparam();

            var reg=new RegExp("\n","g"); //创建正则RegExp对象

            eContent=$("#emailContent").val().replace(reg,"<br/>");

            if(flag == true){

                document.getElementById("send").innerHTML = "发送中...";

                // $("#send").text("发送中...");

                $.ajax({

                    type : "post",

                    url : "/accident/SendEditEmail.do",

                    dataType:"json",

                    data: {"emailer":$("#emailer").val(),"emailTitle":$("#emailTitle").val(),"emailContent":eContent},

                    async : false,

                    success:function (data){

                        document.getElementById("send").innerHTML = "发送";

                        if(data= "ture"){

                            layer.alert("发送成功！", {icon: 6,skin: 'layui-layer-lan',});

                            layer.close(index11)//关闭弹层

                            $("#functontestform").find('input[type=text],select,input[type=date],textarea').each(function() {

                                $(this).val('');

                            });//清空form表单并查询

                            $('#functionTestSelectTable').bootstrapTable('refresh');

                        }else {

                            layer.msg("发送失败，请稍后重试", {icon: 5,skin: 'layui-layer-lan',});

                        }

                    }//success end

                });//ajax end

            }

        });

3.在controller中写发邮件的逻辑，获取前端ajax请求传来的参数，调用SendMail类中的sendMail函数，并传参

    /**

     * 发送邮件编辑

     *

     * @param response

     * @return

     * @throws Exception

     * @param: request

     */

    @RequestMapping(value = "/SendEditEmail.do")

    @ResponseBody

    public String SendEditEmail(@Valid @ModelAttribute("accident") Accident accident, BindingResult br,

                                Model model, HttpServletRequest req, HttpServletResponse response) throws Exception {

        response.setContentType("text/html;charset=utf-8");

        req.setCharacterEncoding("utf-8");

        //收件人

        String emailer = req.getParameter("emailer").trim();

        //邮件标题

        String emailTitle = req.getParameter("emailTitle").trim();

        //邮件内容

        String emailContent = req.getParameter("emailContent").trim();

        //处理文件内容使用

        ArrayList<String> list = new ArrayList<>();

        System.out.println(emailContent);

        //发送邮件

        String status="false";

        if(emailer != "" && emailTitle != "" && emailContent != "")

        {

            List emailerList = new ArrayList();//不能使用string类型的类型，这样只能发送一个收件人

            String []median=emailer.split(",");//对输入的多个邮件进行逗号分割

            for(int i=0;i<median.length;i++){

                emailerList.add(new InternetAddress(median[i]));

            }

            InternetAddress[] address =(InternetAddress[])emailerList.toArray(new InternetAddress[emailerList.size()]);

//            System.out.println("收件人所在数组-----"+address);

            for(int i=0;i<address.length;i++){

                status=SendMail.sendMail(address[i],emailTitle,emailContent);

            }

        }

        return status;

    }

4.在这之前需要配置邮箱信息 ------global.properties

#设置邮箱服务器
mailHost=smtp.163.com

#设置邮箱端口号

mailPort=25

#设置邮箱服务器的用户名

mailUsername=aaaa@163.com

#授权码（注意不是邮箱登录密码）

mailPassword=BMT856

#设置超时时间

mailTimeout=25000

#设置发件人

mailFrom=aaaa@163.com

5.开发获取配置文件的工具类

package luckyweb.seagull.util;

import java.io.IOException;

import java.io.InputStream;

import java.util.Properties;

/**

 * @author lw

 * @createTime 2018/6/25 15:27

 * @description 获取配置文件类

 */

public class ProUtil {

    private static final String PROPERTIES_DEFAULT = "global.properties";

    public static String host;

    public static Integer port;

    public static String userName;

    public static String passWord;

    public static String emailForm;

    public static String timeout;

    public static String personal;

    public static Properties properties;/**

     * 初始化

     */

    private static void init() {

        properties = new Properties();

        try {

            InputStream inputStream = ProUtil.class.getClassLoader().getResourceAsStream(PROPERTIES_DEFAULT);

            properties.load(inputStream);

            inputStream.close();

            //properties.setProperty("mailFrom","cuizhixiang@feitu.biz");

            host = properties.getProperty("mailHost");

            port = Integer.parseInt(properties.getProperty("mailPort"));

            userName = properties.getProperty("mailUsername");

            passWord = properties.getProperty("mailPassword");

            emailForm = properties.getProperty("mailFrom");

            timeout = properties.getProperty("mailTimeout");

            personal = "测试部";//发件人的别名

        } catch (IOException e) {

            e.printStackTrace();

        }

    }

}

6.开发发送邮件的实现类

package luckyweb.seagull.util;

import org.springframework.mail.javamail.JavaMailSenderImpl;

import org.springframework.mail.javamail.MimeMessageHelper;

import javax.mail.MessagingException;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

import java.io.UnsupportedEncodingException;

import java.util.Properties;

/**

 * @author lw

 * @createTime 2018/6/25 15:24

 * @description 服务端邮件类

 */

public class SendMail {

    private static final String HOST = ProUtil.host;

    private static final Integer PORT = ProUtil.port;

    private static final String USERNAME = ProUtil.userName;

    private static final String PASSWORD = ProUtil.passWord;

    private static final String emailForm = ProUtil.emailForm;

    private static final String timeout = ProUtil.timeout;

    private static final String personal = ProUtil.personal;

    private static JavaMailSenderImpl mailSender = createMailSender();

    private SendMail(){}

    /**

     * 邮件发送器

     *

     * @return 配置信息工具

     */

    private static JavaMailSenderImpl createMailSender() {

        JavaMailSenderImpl sender = new JavaMailSenderImpl();

        sender.setHost(HOST);

        sender.setPort(PORT);

        sender.setUsername(USERNAME);

        sender.setPassword(PASSWORD);

        sender.setDefaultEncoding("Utf-8");

        Properties p = new Properties();

        p.setProperty("mail.smtp.timeout", timeout);

        p.setProperty("mail.smtp.auth", "true");

        sender.setJavaMailProperties(p);

        return sender;

    }

    /**

     * 发送邮件

     *

     * @param to 接受人

     * @param subject 主题

     * @param html 发送内容

     * @throws :MessagingException 异常

     * @throws :UnsupportedEncodingException 异常

     */

    public static String sendMail(InternetAddress to, String subject, String html) throws MessagingException,UnsupportedEncodingException {

        MimeMessage mimeMessage = mailSender.createMimeMessage();

        // 设置utf-8或UTF-8编码，否则邮件会有乱码

        MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage, true, "UTF-8");

        messageHelper.setFrom(emailForm, personal);

        messageHelper.setTo(to);

        messageHelper.setSubject(subject);

        messageHelper.setText(html, true);

        mailSender.send(mimeMessage);

        return "true" ;

    }

    public static void main(String[] args) {

        String ss = "项目名称： 合肥通 事故状态： 跟踪处理完成 事故等级： 五级及以下事故 发生时间： 2018-06-11 13:52:42 事故原因类型： 紧急上线-未测试 事故描述： 线上事故 事故原因分析： 事故原因分析 受影响范围： 受影响范围 纠正处理过程： 纠正处理过程" +

                "(需点名责任人) 解决时间： 2018-06-11 13:53:25 事故汇报人： 张美丽";

        for (int i = 0; i < ss.length(); i++) {

            if(ss.equals(":"))

                break;

            String new_ss =ss.replace(" ","<br>");

            System.out.print(new_ss);

        }

           /* String subject = "html邮件测试"; // subject javamail自动转码

            StringBuffer theMessage = new StringBuffer();

            theMessage.append("<h2><font color=red>加油</font></h2>");

            theMessage.append("<hr>");

            theMessage.append("<i>美丽的开始</i>");

            theMessage.append("<table border='1'><tr><td>aaa</td><td>bbb</td></tr><tr><td>ccc</td><td>ddd</td></tr></table>");

        try {

            SendMail.sendMail("357712148@qq.com",subject,theMessage.toString());

        } catch (MessagingException e) {

            e.printStackTrace();

        } catch (UnsupportedEncodingException e) {

            e.printStackTrace();

        }

        System.out.println("运行结果！！");*/

    }

}

到此大功告成，支持发送多人，用，隔开。
