unable to find valid certification path to requested target and ‘parent.relativePath’ points at no local POM

解决方案：
把这个

 <parent>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-parent</artifactId>
      <version>1.5.10.RELEASE</version>
      <relativePath/>
  </parent>

换成

 <parent>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-parent</artifactId>
      <version>1.5.10.RELEASE</version>
  </parent>
