Resolve issues that are not referenced by the Springboot Project MAVEN packaging project

Do not use the plugin that comes with springboot, because this package will be packaged in the Spring-boot directory to cause other project references to not be referenced

Modify the following location

<plugin>        <groupId>org.springframework.boot</groupId>        <artifactId> Spring-boot-maven-plugin</artifactid></plugin>

Instead, use this plugin:

 <Plugin>
 <Artifactid>maven-compiler-plugin</artifactid ; 
  <version  >2.3.2  </version ; 
  <configuration ; 
  << Span style= "color: #000080; Font-weight:bold ">source  >1.8  </source  
  <target  >1.8  </target ; 
  </configuration ; 
  </plugin ;
