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
• 前一篇博文是通过HTTP代理解决，但是如果我们没有代理呢，该咋整。
• 使用国内镜像才是王道呀！

四、使用国内镜像

• 新建一个配置文件settings.xml

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
					  https://maven.apache.org/xsd/settings-1.0.0.xsd">
	<mirrors>
		<mirror>  
			<id>alimaven</id>  
			<name>aliyun maven</name>  
			<url>http://maven.aliyun.com/nexus/content/groups/public/</url>  
			<mirrorOf>central</mirrorOf>          
		</mirror>  

		<mirror>
			<id>huaweicloud</id>
			<mirrorOf>*</mirrorOf>
			<name>huaweicloud</name>
			<url>https://mirrors.huaweicloud.com/repository/maven/</url>
		</mirror>

		<mirror>
			<id>tencent</id>
			<mirrorOf>*</mirrorOf>
			<name>tencent</name>
			<url>http://mirrors.cloud.tencent.com/nexus/repository/maven-public/</url>
		</mirror>

		<mirror>
			<id>163</id>
			<mirrorOf>*</mirrorOf>
			<name>163</name>
			<url>http://mirrors.163.com/maven/repository/maven-public/</url>
		</mirror>

	</mirrors>
</settings>

• 文件->设置->构建、执行、部署->构建工具->Maven->用户设置文件

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
