1、项目介绍

1）项目功能

用户管理：分为管理员、和普通用户，设置不同用户的权限

电话本信息管理：支持管理员和普通用户对电话本的信息进行增删改操作，模糊查询（根据姓名、地址、单位）

文件批量导入：支持管理员通过excel文件批量导入电话本信息

分页功能：对电话本信息管理页面支持分页查看

电话本分组管理：对电话本进行分组，修改、移动、删除

邮件发送名片功能：支持管理员根据电话本信息向用户发送邮件，邮件内容为个人信息名片和附件

用户信息导出功能：导出个人用户的用户信息word文档

2）技术栈描述

前端 html+thymeleaf+jquery+css

后端 Spring Boot + Spring MVC + MyBatis Plus

数据库 MySQL

其他技术 POI Excel 、word文件导入导出、JavaMail API邮件发送

2、邮件发送具体实现

1）导入发送邮件需要的依赖

<!--        邮件发送--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId></dependency>

2）添加邮件配置的参数（在application.yml配置文件中)

  mail:host: smtp.qq.com  #qq邮件服务器地址 有其他地址username: xxxxxxx@qq.com #发件人邮箱password: rwcafxsrjxfndfee    #授权码default-encoding: UTF-8 #邮件登录字符集编码port: 25 #发件人邮件服务器端口

授权码的获取：首先登录QQ邮箱>>>登录成功后找到设置>>>然后找到邮箱设置>>>点击账户>>>找到POP3|SMTP服务>>>点击开启(开启需要验证，验证成功后会有一串授权码用于发送邮件使用)>>>验证成功

3）创建邮件发送controller

以发送个人信息为例

    @AutowiredMailUtil mailUtil;/*** 邮件发送名片功能* @param contactId* @param userId* @return*/@RequestMapping("/sendEmailCard")public void sendEmailCard(Integer contactId, Integer userId){Contacts contacts = this.contactsService.getById(contactId);Users user = this.usersService.getById(contacts.getUserId());Integer gender0 = contacts.getGender();String gender = "男";if(gender0==1){gender="女";}String email = contacts.getEmail();String content="<html><body><h1>个人名片</h1><p>姓名：" +user.getUsername()+"</p><p>单位：" +contacts.getCompany()+"</p><p>性别：" +gender+"</p><p>年龄：" +contacts.getAge()+"</p><p>办公电话：" +contacts.getOfficePhone()+"</p><p>传真：" +contacts.getFax()+"</p><p>手机号码：" +contacts.getMobile()+"</p><p>电子邮件：" +contacts.getEmail()+"</p><p>地址：" +contacts.getAddress()+"</p><p>备注：" +contacts.getRemarks()+"</p></body></html>";String imgPath = "D:\\email\\个人信息表.docx";mailUtil.sendAttachmentsMail(email, "主题：电话信息验证", content, imgPath);}

4) 引入邮件发送工具包

package com.qcby.onlinephonebook.util;import org.springframework.beans.factory.annotation.Autowired;
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.Component;import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;/*** <p><p/>** @Author: porridge* @Date:2022/3/30 10:17*/
@Component
public class MailUtil {@Value("${spring.mail.username}")String from;@AutowiredJavaMailSender mailSender;//简单邮件public void sendSimpleMail(String to, String subject, String content){SimpleMailMessage message = new SimpleMailMessage();message.setFrom(from); //发件人message.setTo(to);//收件人message.setSubject(subject); //标题message.setText(content);   //文件内容try {mailSender.send(message);System.out.println("简单邮件发送成功！");} catch (Exception e){System.out.println("发送简单邮件时发生异常！"+e);}}//html格式邮件public void sendHtmlMail(String to, String subject, String content){MimeMessage message = mailSender.createMimeMessage();try {//true表示需要创建一个multipart messageMimeMessageHelper helper = new MimeMessageHelper(message, true);helper.setFrom(from);helper.setTo(to);helper.setSubject(subject);helper.setText(content, true);mailSender.send(message);System.out.println("html邮件发送成功!");} catch (MessagingException e) {System.out.println("发送html邮件时发生异常！"+e);}}//带附件的邮件public void sendAttachmentsMail(String to, String subject, String content, String filePath){MimeMessage message = mailSender.createMimeMessage();try {MimeMessageHelper helper = new MimeMessageHelper(message, true);helper.setFrom(from);helper.setTo(to);helper.setSubject(subject);helper.setText(content, true);FileSystemResource file = new FileSystemResource(new File(filePath));String fileName = filePath.substring(filePath.lastIndexOf(File.separator));helper.addAttachment(fileName, file);mailSender.send(message);System.out.println("带附件的邮件已经发送。");} catch (MessagingException e) {System.out.println("发送带附件的邮件时发生异常！" + e);}}//带静态资源的邮件public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId){MimeMessage message = mailSender.createMimeMessage();try {MimeMessageHelper helper = new MimeMessageHelper(message, true);helper.setFrom(from);helper.setTo(to);helper.setSubject(subject);helper.setText(content, true);FileSystemResource res = new FileSystemResource(new File(rscPath));helper.addInline(rscId, res);mailSender.send(message);System.out.println("嵌入静态资源的邮件已经发送。");} catch (MessagingException e) {System.out.println("发送嵌入静态资源的邮件时发生异常！" + e);}}
}

3、word导出具体实现

1）实现思路

①组装数据

②获取根目录，创建模板文件

③将模板文件写入到根目录

④编译模板，渲染数据

⑤写入到指定目录位置，临时文件

⑥提供前端下载

⑦删除临时文件

2）导入word导出需要的依赖

<!--            word导出--><dependency><groupId>com.deepoove</groupId><artifactId>poi-tl</artifactId><version>1.10.0</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>4.1.2</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>4.1.2</version></dependency>

3）在项目resource目录下创建word模板

word模板如下：

根据需要，{{}}里面写入需要写入的参数名

4）创建word导出的controller

/*** 个人信息word导出* @param response*/@RequestMapping("/exportWord")public void exportWord(Integer contactId, Integer userId, HttpServletResponse response) {Contacts contacts = this.contactsService.getById(contactId);String gender = "男";if(contacts.getGender()==1){gender = "女";}//1.组装数据Map<String, Object> params = new HashMap<>();params.put("name",contacts.getName());params.put("company", contacts.getCompany());params.put("gender", gender);params.put("age", contacts.getAge());params.put("officePhone", contacts.getOfficePhone());params.put("fax", contacts.getFax());params.put("mobile", contacts.getMobile());params.put("email", contacts.getEmail());params.put("address", contacts.getAddress());params.put("remarks", contacts.getRemarks());//2.获取根目录，创建模板文件String path = copyTempFile("word/info.docx");String fileName = System.currentTimeMillis() + ".docx";String tmpPath = "D:\\email\\" + fileName;try {//3.将模板文件写入到根目录//4.编译模板，渲染数据XWPFTemplate template = XWPFTemplate.compile(path).render(params);//5.写入到指定目录位置FileOutputStream fos = new FileOutputStream(tmpPath);template.write(fos);fos.flush();fos.close();template.close();//6.提供前端下载down(response, tmpPath, fileName);} catch (Exception e) {e.printStackTrace();} finally {//7.删除临时文件File file = new File(tmpPath);file.delete();File copyFile = new File(path);copyFile.delete();}}/*** 用于将文件下载到客户端* @param response* @param filePath  文件路径* @param realFileName  文件名称*/private void down(HttpServletResponse response, String filePath, String realFileName) {String percentEncodedFileName = null;try {percentEncodedFileName = percentEncode(realFileName);} catch (UnsupportedEncodingException e) {throw new RuntimeException(e);}StringBuilder contentDispositionValue = new StringBuilder();contentDispositionValue.append("attachment; filename=").append(percentEncodedFileName).append(";").append("filename*=").append("utf-8''").append(percentEncodedFileName);response.addHeader("Access-Control-Allow-Origin", "*");response.addHeader("Access-Control-Expose-Headers", "Content-Disposition,download-filename");response.setHeader("Content-disposition", contentDispositionValue.toString());response.setHeader("download-filename", percentEncodedFileName);try (BufferedInputStream bis = new BufferedInputStream(new FileInputStream(filePath));// 输出流BufferedOutputStream bos = new BufferedOutputStream(response.getOutputStream());) {byte[] buff = new byte[1024];int len = 0;while ((len = bis.read(buff)) > 0) {bos.write(buff, 0, len);}} catch (Exception e) {e.printStackTrace();}}/*** 百分号编码工具方法* @param s 需要百分号编码的字符串* @return 百分号编码后的字符串*/public static String percentEncode(String s) throws UnsupportedEncodingException {String encode = URLEncoder.encode(s, StandardCharsets.UTF_8.toString());return encode.replaceAll("\\+", "%20");}/*** 复制模板文件用于写入，得到临时路径* @param s  模板文件的路径* @return*/private String copyTempFile(String s) {InputStream inputStream = getClass().getClassLoader().getResourceAsStream(s);String tempFileName = System.getProperty("user.home") + "/" + "info.docx";File tempFile = new File(tempFileName);try {FileUtils.copyInputStreamToFile(inputStream, tempFile);} catch (IOException e) {throw new RuntimeException(e);}return tempFile.getPath();}
