【资讯类系统开发经验分享】——SpringBoot+Vue.js汽车资讯论坛系统 汽车资讯分享平台系统 汽车资讯发布平台系统(可视化+在线点播+JavaMail)

## 讲两句
我也是头一次开发资讯类系统，资讯类系统涉及到很多知识点，比如怎么存放图片视频、并发问题。

## 解决方案
软件开发讲究整体的解决方案，所以我给出如下解决方案：
①图片、视频分布式存储，可以考虑集成阿里云平台的OSS，还可以做点播，同时数据比较安全
②开发框架，可以选择现在比较流行的springboot

## 开发技术
前端：Vue + element UI + axios

后端：Spring Boot + MyBatis Plus + Druid

数据库：MySQL

## 如何开发特色的论坛资讯类系统
①JavaMail找回密码

②阿里云OSS对象存储(视频、图片、在线点播)

③前后端分离springboot+vue.js联合开发

④数据可视化统计图表

## 如何设计数据库

```sql
SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for agree
-- ----------------------------
DROP TABLE IF EXISTS `agree`;
CREATE TABLE `agree` (
`essay_id` bigint(20) unsigned NOT NULL COMMENT '动态id',
`user_id` bigint(20) unsigned NOT NULL COMMENT '点赞用户id',
`create_time` varchar(255) NOT NULL COMMENT '点赞时间'
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

-- ----------------------------
-- Table structure for agree_pl
-- ----------------------------
DROP TABLE IF EXISTS `agree_pl`;
CREATE TABLE `agree_pl` (
`comment_id` int(11) NOT NULL COMMENT '评论id',
`user_id` bigint(20) NOT NULL COMMENT '点赞用户id',
`create_time` varchar(255) NOT NULL COMMENT '创建时间'
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

-- ----------------------------
-- Table structure for attention
-- ----------------------------
DROP TABLE IF EXISTS `attention`;
CREATE TABLE `attention` (
`that_id` bigint(20) unsigned NOT NULL COMMENT '关注id',
`this_id` bigint(20) unsigned NOT NULL COMMENT '用户id',
`create_time` varchar(255) NOT NULL COMMENT '关注时间'
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
```

大家记住设计数据库一定要用navicat设计注释这样比较方便 如下：

## 代码设计

实现代码如下：

```java
package com.superb.util;

import cn.hutool.core.util.IdUtil;
import org.springframework.beans.factory.annotation.Autowired;
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;
import java.util.UUID;

/**
* 发送邮件工具类
* @author Superb
* @date 2020/11/12 - 16:45
* @E_mail superb12580@163.com
*/
@Component
public class SendMail {
@Autowired
private JavaMailSender mailSender;

private static final String subject = "来自汽车之家";
private static final String url = "http://localhost:8080/car";
private static final String imgUrl = "C:\\Users\\HP\\Desktop\\汽车之家\\ProjectCode\\SpringBootCar\\src\\main\\resources\\img\\Logo2.png";
private static final String fromUrl = "superb12580@163.com";

/**
* 不带附件
* @param toUrl
* @return
* @throws MessagingException
*/
public String sendMail(String toUrl) throws MessagingException {
MimeMessage mimeMessage = mailSender.createMimeMessage();
MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage,true);
mimeMessageHelper.setSubject(subject);
//生成随机验证码
String code = IdUtil.simpleUUID().substring(0, 6).toUpperCase();

mimeMessageHelper.setText("【汽车之家】欢迎注册<a href=\""+url+"\">汽车之家</a>，您本次的验证码为<b style=\"color:red\">"+code+"</b>，五分钟内有效，感谢使用。",true);
mimeMessageHelper.setTo(toUrl);
mimeMessageHelper.setFrom(fromUrl);
mailSender.send(mimeMessage);
return code;
}

/**
* 带附件
* @param toUrl
* @return
* @throws MessagingException
*/
public String sendMailHelper(String toUrl) throws MessagingException {

MimeMessage mimeMessage = mailSender.createMimeMessage();
MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage,true);
mimeMessageHelper.setSubject(subject);

//上传文件
mimeMessageHelper.addAttachment("汽车之家",new File(imgUrl));

//生成随机验证码
String code = UUID.randomUUID().toString().substring(0,6).toUpperCase();
mimeMessageHelper.setText("【汽车之家】欢迎注册<a href=\""+url+"\">汽车之家</a>，您本次的验证码为<b style=\"color:red\">"+code+"</b>，五分钟内有效，感谢使用。",true);
mimeMessageHelper.setTo(toUrl);
mimeMessageHelper.setFrom(fromUrl);

mailSender.send(mimeMessage);

return code;
}
}

```

实现代码如下：

```java
package com.superb;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@EnableScheduling
@SpringBootApplication
public class CarApplication {

public static void main(String[] args) {
SpringApplication.run(CarApplication.class, args);
}

}

```

## 总体展望
开发论坛类系统 1要考虑好技术选型——springboot 2处理好图片的容灾备份
