错误提示:

** WARNING ** : Your ApplicationContext is unlikely to start due to a @ComponentScan of the default package
// 警告:你的应用上下文可能没有启动,因为你将注解添加到了默认的package上面了

原因解析:

SpringBoot在写启动类的时候如果不使用@ComponentScan指明对象扫描范围,默认指扫描当前启动类所在的包里的对象,如果当前启动类没有包,则在启动时会报错:Your ApplicationContext is unlikely to start due to a @ComponentScan of the default package错误。
因为启动类不能直接放在main/java文件夹下,必须要建一个包把它放进去或者使用@ComponentScan指明要扫描的包。

解决方法:

  方法一:在main/java下建个包,将Application文件放进去;

  方法二:在Application类上面加@ComponentScan注解,指定要扫描的包,如下: 

@SpringBootApplication
@EnableEurekaClient
@ComponentScan(basePackageClasses = TestClass.class )
public class ClientDemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(ClientDemoApplication.class, args);
    }
}

    @ComponentScan(basePackageClasses=要扫描类.class所在位置的包)-意思是要扫描哪个类所在的包
