一、前言

遇到这个问题，有两种解决办法

• IDEA Maven使用HTTP代理，解决Could not transfer artifact org.xxx问题
• IDEA Maven使用国内镜像，解决Could not transfer artifact org.xxx问题

二、遇到问题

• 使用IDEA运行一个Java Demo时，遇到一个问题：Could not transfer artifact org.xxx

Connection refused: connect

org.springframework.boot:spring-boot-starter-parent:pom:3.3.2 failed to transfer from https://repo.maven.apache.org/maven2 during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:3.3.2 from/to central (https://repo.maven.apache.org/maven2): transfer failed for https://repo.maven.apache.org/maven2/org/springframework/boot/spring-boot-starter-parent/3.3.2/spring-boot-starter-parent-3.3.2.pom

Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:3.3.2 from/to central (https://repo.maven.apache.org/maven2): transfer failed for https://repo.maven.apache.org/maven2/org/springframework/boot/spring-boot-starter-parent/3.3.2/spring-boot-starter-parent-3.3.2.pom

三、分析问题

根本原因就是https://repo.maven.apache.org/maven2网址无法访问

四、HTTP代理

• 无法直接访问https://repo.maven.apache.org/maven2，那就开代理访问吧
  
• 打开代理后，再通过浏览器确定能够访问到https://repo.maven.apache.org/maven2
  
• 在IDEA中HTTP配置了代理
  

五、重新编译验证

• 点击Maven刷新按钮，重新加载所有Maven项目
• Maven Clean

问题解决，撒花🎉~
