如题，配置文件如下：

#注册中心配置

    instanceId: ${spring.application.name}:${random.int}

    serviceUrl:

然后使用注解@ConfigurationProperties读取配置文件

错误原因：

这里使用的配置文件是yml文件而不是properties文件，

所以读取资源文件的时候，

如果是读取yml文件，则应该配置成：

public static final String PREFIX = "zebra:rocketmq";

如果是读取properties文件，则应该配置成：

public static final String PREFIX = "zebra.rocketmq";

是真的恶心！！！！！
