创建spring boot+Mybatis项目全流程

第一步：打开IDEA 【New -> Project】

第二步：选择Spring Initializr
第三步：输入Name以及相关配置，可以参考截图
注意：Server URL 出可以替换为阿里云镜像【https://start.aliyun.com】速度更快

第四步：选择相关依赖

我这里只是选择了一些基本的依赖，大家可以按需添加，或者后面再在pom文件里面添加依赖也可以。

第五步：配置数据源，打开【application】文件

server:
  port: 8080	#设置端口号

#数据源
spring:
  datasource:#配置需要连接的数据库表名【kg_one】
    url: jdbc:mysql://localhost:3306/kg_one?seUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8
    username: *** #数据库账号
    password: *** #数据库密码
    driver-class-name: com.mysql.cj.jdbc.Driver

如果提示【com.mysql.cj.jdbc.Driver】有问题，请检查pom文件中是否有以下依赖


<!--       JDBC  -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jdbc</artifactId>
        </dependency>
<!--        Mysql -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.29</version>
        </dependency>
<!--      Mybatis   -->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.5.1</version>
        </dependency>

到这一步，不出意外的话，您单击小绿以后就能看到如下界面了。恭喜您，搭建完毕，可以开始了。
