修改pom.xml檔案，用如下方式實現
<properties>
    <!-- The main class to start by executing java -jar -->
    <start-class>com.microservice.MicroserviceOrderApplication</start-class

</properties>

2 在Spring-boot-maven外掛中配置

<properties>
    <!-- The main class to start by executing java -jar -->
    <start-class>com.microservice.MicroserviceOrderApplication</start-class>
</properties>
