Java 之 Spring Boot + Vue + Element UI 前后端分离项目（上-项目搭建） 【博客论坛项目高仿CSDN】（一篇文章精通系列）
一、项目简介
1、JDK1.8 SpringBoot 2.6.2 mybatis2.2.0
2. Vue3
3. 使用工具 后端IDEA 和 前端HBuilderX
4、数据库使用mysql5.5 SQL文件
SQL文件下载

二、后端SpringBoot项目搭建
1、项目搭建
（1）创建工程
（2）引入依赖

（3）创建其他项目文件以及配置文件
1)启动类
package cn.itbluebox.springbootcsdn;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringBootCSDNApplication
public static void main(String[] args)
SpringApplication.run(SpringBootCSDNApplication.class, args);
2)配置文件
application.yml
server:
port: 9090
#datasource
spring:
datasource:
url: jdbc:mysql:///csdn
username: root
password: root
driver-class-name: com.mysql.jdbc.Driver
mvc:
view:
prefix: /
suffix: .jsp
mybatis:
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
sc:
jwt:
secret: blueboxai@Login(Auth*^31)&heiMa% # 登录校验的密钥
pubKeyPath: C:\\\\Users\\\\ZHENG\\\\Desktop\\\\leyou_msgrs\\\\rsa\\\\rsa.pub # 公钥地址
priKeyPath: C:\\\\Users\\\\ZHENG\\\\Desktop\\\\leyou_msgrs\\\\rsa\\\\rsa.pri # 私钥地址
expire: 30 # 过期时间,单位分钟
cookieName: SC_TOKEN
cookieMaxAge: 1200
3)webapp
设置文件类型
4)创建完整的目录结构
创建方式都一样省略不写
运行测试
运行成功，工程搭建的没有问题
2、编写数据库对应的实体类
（1）Blog
package cn.itbluebox.springbootcsdn.domain;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import javax.persistence.Transient;
import java.util.Date;
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Blog
private Long id; //文章id
private String title; //文章标题
private String abstract_text; //文章内容
private String thumbnail; //缩略图
private Date create_time; //创建时间
private Long like_count; //点赞数量
private Long view_count; //浏览量
private Long consumer_id; //用户ID
private String type_id; //类型
private Long blog_article_id; //博客文章ID
@Transient //Transient声明当前字段不是数据对应的字段
private Long[] typeId;
（2）BlogArticle
package cn.itbluebox.springbootcsdn.domain;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import javax.persistence.Table;
import java.util.Date;
@Data
@NoArgsConstructor
@AllArgsConstructor
@Table(name = "blog_article")
public class BlogArticle
private Long id;
private String context;
private Date last_update_time; //更新时间
private Character is_original;
（2）BlogHeader
package cn.itbluebox.springbootcsdn.domain;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import javax.persistence.Table;
import javax.persistence.Transient;
@Data
@NoArgsConstructor
@AllArgsConstructor
@Table(name = "blog_header")
public class BlogHeader
private Long id;
private Long blog_id;
private String title;
private String abstract_text;
private String type;
@Transient //Transient声明当前字段不是数据对应的字段
private String thumbnail;
（3）BlogType
package cn.itbluebox.springbootcsdn.domain;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import javax.persistence.Table;
@Data
@NoArgsConstructor
@AllArgsConstructor
@Table(name = "blog_type")
public class BlogType
private Long id;
private String typename;
（4）Consumer
package cn.itbluebox.springbootcsdn.domain;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import javax.persistence.Table;
import javax.persistence.Transient;
import java.util.Date;
@Data
@NoArgsConstructor
@AllArgsConstructor
@Table(name = "consumer")
public class Consumer
private Long id;
private Character sex;
private String name;
private String email;
private String image;
private String type;
private Long phone;
private Date birthday;
private String password;
@Transient //Transient声明当前字段不是数据对应的字段
private String token;
3、编写枚举类ExceptionEnum
