本文介绍了如何在本地环境中配置JDK8、Maven3.6.3以及阿里云镜像，同时详细说明了如何在SpringBoot项目中引入MyBatis-Plus并配置MySQL数据库。包括设置Maven仓库、添加SpringBoot依赖和数据库连接配置。

1.基于jdk8与本地

环境准备

1)下载jdk8并安装

2）下载maven 3.6.3并解压放入D盘maven目录下，去掉外层

设置阿里源

打开settings.xml,在mirrors标签之内增加，注意粘贴后</id>中的/有可能被删掉，要自己补上

    <mirror>

        <id>nexus-aliyun</id>

         <mirrorOf>central</mirrorOf>

          <name>Nexus aliyun</name>

        <url>http://maven.aliyun.com/nexus/content/groups/public</url>

     </mirror>

大概位置

再建立一个reposity

3）idea关闭项目

All settings

overide都要选

新建项目

注意server url要改成aliyun，才能在JDK中选到1.8 JAVA 8

https://start.aliyun.com/

选择aliyun也有代价，就是 pom没有parent标签，但没什么影响

另外即使没有启动按钮（就是下面右边绿色箭头），需要自己配置

确保这里已经选择

在Edit configuration中修改

引入mybaitis-plus

   <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.5.1</version>
        </dependency>

pom.xml全文是：

数据库配置

另外也为在新建项目时选择了mysql

所以要进行数据库配置 main/resources下增加application.yml

server:
  port: 9090
spring:
   datasource:
      driver-class-name: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://localhost:3306/test1?serverTimezone=GMT%2b8
      username: root
      password: 123456
