解决Unable to find a single main class from the following candidates

SpringBoot打包异常提示：Unable to find a single main class from the following candidates

说明该项目中有很多main方法，需要制定一个main方法的入口。

在maven项目中加上这个，指定入口和启动类型

<build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><!-- 指定该Main Class为全局的唯一入口 --><mainClass>com.bsj.boyun.open.car.BoyunOpenCarApplication</mainClass><layout>ZIP</layout></configuration><executions><execution><goals><goal>repackage</goal><!--可以把依赖的包都打包到生成的Jar包中--></goals></execution></executions></plugin></plugins></build>
