3.1 在application.yml中配置数据库信息

spring:datasource:driver-class-name: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://localhost:3306/big_eventusername: rootpassword: 1234

4.1 创建包结构

tips: 有情况下idea中包结构是.形式的没有铺开，可以按图示方式转换成普通的包结构显示

4.2 根据数据库表创建实体类

4.2.1 Article

package com.geji.pojo;import java.time.LocalDateTime;public class Article {private Integer id;//主键IDprivate String title;//文章标题private String content;//文章内容private String coverImg;//封面图像private String state;//发布状态 已发布|草稿private Integer categoryId;//文章分类idprivate Integer createUser;//创建人IDprivate LocalDateTime createTime;//创建时间private LocalDateTime updateTime;//更新时间
}

4.2.2 Category

package com.geji.pojo;import java.time.LocalDateTime;public class Category {private Integer id;//主键IDprivate String categoryName;//分类名称private String categoryAlias;//分类别名private Integer createUser;//创建人IDprivate LocalDateTime createTime;//创建时间private LocalDateTime updateTime;//更新时间
}

4.2.3 User

package com.geji.pojo;import java.time.LocalDateTime;public class User {private Integer id;//主键IDprivate String username;//用户名private String password;//密码private String nickname;//昵称private String email;//邮箱private String userPic;//用户头像地址private LocalDateTime createTime;//创建时间private LocalDateTime updateTime;//更新时间
}

注意命名方式，实体类为驼峰，数据库为下划线

5.1 更改启动类名字，并编写相应代码

package com.geji;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;/*** Hello world!**/
@SpringBootApplication
public class BigEventApplication
{public static void main( String[] args ){SpringApplication.run(BigEventApplication.class,args);}
}

6.1 启动，不报错则创建环境成功

tips：

7.1 以上实体类没有getter,setter等方法，可以使用lombok在编辑阶段自动生成

7.1.1 在依赖中引入lombok

<!--    lombok依赖--><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency>

7.1.2 在实体类上加入@Data注解

7.1.3 在maven中重新编译，然后在target文件夹中就会发现编译好的实体类中有getter,setter等方法了
