利用javax.mail发送邮件,图片与附件都可发送
1,Controller类
package com.web.controller.api; import javax.annotation.Resource; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import com.service.EmailService; @Controller @RequestMapping("api") public class EmailTaskController { private static final Logger logger = LoggerFactory.getLogger(EmailTaskController.class); @Resource EmailService emailService; @RequestMapping("sendEmailTask") public void sendEmailTask() { logger.info("-------------执行发送邮件START---------------"); //写入excel //insuranceService.excelManage(); //发邮件 emailService.emailManage(); logger.info("-------------执行发送邮件END---------------"); } }
2,service类
package com.service.impl; import java.io.File; import java.util.ArrayList; import java.util.Date; import java.util.HashMap; import java.util.Iterator; import java.util.List; import java.util.Map; import javax.annotation.Resource; import javax.mail.MessagingException; import javax.mail.internet.MimeMessage; import org.apache.log4j.Logger; import org.springframework.beans.factory.annotation.Value; import org.springframework.core.io.FileSystemResource; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.mail.javamail.MimeMessageHelper; import org.springframework.stereotype.Service; import com.entity.MailModel; import com.service.EmailService; import com.SimpleException; @Service public class EmailServiceImpl implements EmailService { private static Logger logger = Logger.getLogger(EmailServiceImpl.class); private String excelPath = "d://"; @Resource private JavaMailSender javaMailSender; @Resource private SimpleMailMessage simpleMailMessage; @Override public void emailManage(){ MailModel mail = new MailModel(); //主题 mail.setSubject("清单"); //附件 Mapattachments = new HashMap (); attachments.put("清单.xlsx",excelPath+"清单.xlsx"); mail.setAttachments(attachments); //内容 StringBuilder builder = new StringBuilder(); builder.append("你好!
"); builder.append("    附件是个人清单。
"); builder.append("    其中人信息;
"); builder.append(""); String cOntent= builder.toString(); mail.setContent(content); sendEmail(mail); } /** * 发送邮件 * * @author chenyq * @date 2016-5-9 上午11:18:21 * @throws Exception */ @Override public void sendEmail(MailModel mail) { // 建立邮件消息 MimeMessage message = javaMailSender.createMimeMessage(); MimeMessageHelper messageHelper; try { messageHelper = new MimeMessageHelper(message, true, "UTF-8"); // 设置发件人邮箱 if (mail.getEmailFrom()!=null) { messageHelper.setFrom(mail.getEmailFrom()); } else { messageHelper.setFrom(simpleMailMessage.getFrom()); } // 设置收件人邮箱 if (mail.getToEmails()!=null) { String[] toEmailArray = mail.getToEmails().split(";"); ListtoEmailList = new ArrayList (); if (null == toEmailArray || toEmailArray.length <= 0) { throw new SimpleException("收件人邮箱不得为空!"); } else { for (String s : toEmailArray) { if (s!=null&&!s.equals("")) { toEmailList.add(s); } } if (null == toEmailList || toEmailList.size() <= 0) { throw new SimpleException("收件人邮箱不得为空!"); } else { toEmailArray = new String[toEmailList.size()]; for (int i = 0; i > it = mail.getPictures().entrySet() .iterator(); it.hasNext();) { Map.Entry entry = it.next(); String cid = entry.getKey(); String filePath = entry.getValue(); if (null == cid || null == filePath) { throw new RuntimeException("请确认每张图片的ID和图片地址是否齐全!"); } File file = new File(filePath); if (!file.exists()) { throw new RuntimeException("图片" + filePath + "不存在!"); } FileSystemResource img = new FileSystemResource(file); messageHelper.addInline(cid, img); } } // 添加附件 if (null != mail.getAttachments()) { for (Iterator > it = mail.getAttachments() .entrySet().iterator(); it.hasNext();) { Map.Entry entry = it.next(); String cid = entry.getKey(); String filePath = entry.getValue(); if (null == cid || null == filePath) { throw new RuntimeException("请确认每个附件的ID和地址是否齐全!"); } File file = new File(filePath); if (!file.exists()) { throw new RuntimeException("附件" + filePath + "不存在!"); } FileSystemResource fileResource = new FileSystemResource(file); messageHelper.addAttachment(cid, fileResource); } } messageHelper.setSentDate(new Date()); // 发送邮件 javaMailSender.send(message); logger.info("------------发送邮件完成----------"); } catch (MessagingException e) { e.printStackTrace(); } } }
MailModel实体类
package com.support.entity; import java.util.Map; public class MailModel { /** * 发件人邮箱服务器 */ private String emailHost; /** * 发件人邮箱 */ private String emailFrom; /** * 发件人用户名 */ private String emailUserName; /** * 发件人密码 */ private String emailPassword; /** * 收件人邮箱,多个邮箱以“;”分隔 */ private String toEmails; /** * 邮件主题 */ private String subject; /** * 邮件内容 */ private String content; /** * 邮件中的图片,为空时无图片。map中的key为图片ID,value为图片地址 */ private Mappictures; /** * 邮件中的附件,为空时无附件。map中的key为附件ID,value为附件地址 */ private Map attachments; private String fromAddress;//发送人地址1个 private String toAddresses;//接收人地址,可以为很多个,每个地址之间用";"分隔,比方说450065208@qq.com;lpf@sina.com private String[] attachFileNames;//附件 public String getFromAddress() { return fromAddress; } public void setFromAddress(String fromAddress) { this.fromAddress = fromAddress; } public String getToAddresses() { return toAddresses; } public void setToAddresses(String toAddresses) { this.toAddresses = toAddresses; } 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; } public String[] getAttachFileNames() { return attachFileNames; } public void setAttachFileNames(String[] attachFileNames) { this.attachFileNames = attachFileNames; } public String getEmailHost() { return emailHost; } public void setEmailHost(String emailHost) { this.emailHost = emailHost; } public String getEmailFrom() { return emailFrom; } public void setEmailFrom(String emailFrom) { this.emailFrom = emailFrom; } public String getEmailUserName() { return emailUserName; } public void setEmailUserName(String emailUserName) { this.emailUserName = emailUserName; } public String getEmailPassword() { return emailPassword; } public void setEmailPassword(String emailPassword) { this.emailPassword = emailPassword; } public String getToEmails() { return toEmails; } public void setToEmails(String toEmails) { this.toEmails = toEmails; } public Map getPictures() { return pictures; } public void setPictures(Map pictures) { this.pictures = pictures; } public Map getAttachments() { return attachments; } public void setAttachments(Map attachments) { this.attachments = attachments; } }
spring.xml添加配置信息
<&#63;xml version="1.0" encoding="UTF-8"&#63;>${mail.host} true 25000 ${mail.username} ${mail.password} UTF-8
dev.properties配置
# email configuration mail.host=smtp.163.com mail.username=chenyanqing5945 mail.password=123456 mail.from=chenyanqing5945@163.com#发件人 mail.to=164792930@qq.com#收件人(多个用,隔开) mail.subject=testEmail #主题
