中间有一个报错问题:Non-resolvable parent POM for com.wujialiang:web02:0.0.1-SNAPSHOT: The following artifacts could not be resolved: org.springframework.boot:spring-boot-starter-parent:pom:3.1.1 (present, but unavailable): org.springframework.boot:spring-boot-starter-parent:pom:3.1.1 failed to transfer from http://0.0.0.0/ during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of maven-default-http-blocker has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:3.1.1 from/to maven-default-http-blocker (http://0.0.0.0/): Blocked mirror for repositories: [nexus-aliyun (http://maven.aliyun.com/nexus/content/groups/public, default, releases)]

这是配置的问题，修改maven的setting.xml
去除无用配置
