使用IDEA创建SpringBoot+MyBatis+MySQL进行项目搭建
文件 --> 新建 --> 项目 填写项目基本信息 项目名称、存放位置、项目语言、项目类型、JDK版本、打包
Web选项选择Spring Web?
?SQL选项中勾选JDBC API、MyBatis Framework、MySQl Driver选项
?至此一个空项目创建完毕(查看pom.xml maven依赖文件如下)
<?xml version="1.0" encoding="UTF-8"?>

此时运行启动类文件报错如下:
原因分析:原因是由于没有配置数据源信息
解决方法:需要在application.properties文件中配置数据源信息
spring.datasource.url=jdbc:mysql://localhost:3306/scoreDB?serverTimezone=UTC&&characterEncoding=UTF-8
spring.datasource.password=123456
spring.datasource.username=root
至此运行成功,默认端口号8080? ?访问地址:http://localhost:8080
#端口号配置
server.port=9099
#数据源相关配置
spring.datasource.url=jdbc:mysql://localhost:3306/scoreDB?serverTimezone=UTC&&characterEncoding=UTF-8
spring.datasource.password=123456
spring.datasource.username=root
#mybatis映射对应的实体类位置
mybatis.type-aliases-package=com.learn.system.pojo
#mybatis的映射xml文件路径位置
mybatis.mapper-locations=classpath:/mapper/*Mapper.xml
