springboot+maven pom文件保错问题

今天闲来无事，自己搭了一个springboot+maven框架，可搭建后，pom文件一直报错报错如下:

Project build error: Non-resolvable parent POM for com.example:demo:0.0.1-SNAPSHOT: Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:1.5.8.RELEASE from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be 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:1.5.8.RELEASE from/to central (https://repo.maven.apache.org/maven2): connect timed out and 'parent.relativePath' points at wrong local POM

经过仔细排查  发现只需改成这样就行：

需要注意的是：有时会提示

spring-boot-starter-test包不存在，然后编译器也无法下载，这时可以去maven仓库看看这个包对应的版本号，修改即可
