详解springboot项目带Tomcat和不带Tomcat的两种打包方式

<build>
  <plugins>
    <!--打包为jar时指定main入口-->
    <plugin>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-maven-plugin</artifactId>
      <!--这里写上main方法所在类的路径-->
      <configuration>
        <mainClass>com.sh.tool.YnToolApplication</mainClass>
      </configuration>

          </goals>
        </execution>
      </executions>
    </plugin>
    <!--忽略Junit代码-->

mvn clean package

java -jar <.jar文件名>
