springboot-mybatis项目

一、后端开发环境搭建

1、File->New->Projet

2选择 Spring Initializr ，然后选择默认的 url 点击next

3勾选Spring Web、SQL模板，next

4点击finish，搭建完成

二 数据库

1 新建数据库

2 执行sql建表

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

三 后端开发过程

1更新pom.xml

    4.0.0

    com.example
    demo
    0.0.1-SNAPSHOT
    springboot-mybatis

    
    
        org.springframework.boot
        spring-boot-starter-parent
        2.1.3.RELEASE
    

    
        1.2.0
        5.1.39
    

    

        
        
            org.springframework.boot
            spring-boot-starter-web
        

        
        
            org.springframework.boot
            spring-boot-starter-test
            test
        

        
        
            org.mybatis.spring.boot
            mybatis-spring-boot-starter
            ${mybatis-spring-boot}
        

        
        
            mysql
            mysql-connector-java
            ${mysql-connector}
        

        
        
            junit
            junit
            4.12
        
        
            org.junit.jupiter
            junit-jupiter
            RELEASE
            test
        
    

2更新 application.properties（这里使用properties，但更推荐使用yaml）

## 数据源配置
spring.datasource.url=jdbc:mysql://localhost/first?useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

## Mybatis 配置
mybatis.typeAliasesPackage=org.spring.springboot.domain
mybatis.mapperLocations=classpath:mapper/*.xml

## 端口
server.port=8081
