如果你去百度/Google，那么你得到最多的答案是，在yml(properties)文件中设置：
eureka:
client:
registerWithEureka: false
fetchRegistry: false
如果错误是在server端报出的，当然，首先必须要进行设置这两个参数。但是如果是在客户端，一般是不用设置的。即便是设置了，也不会报错。
但是，我设置了，异常依然存在。经过很久的思考，我发现还有个问题会引起这个错误——application.yml文件编写错误，或者application.yml文件名不是“application”，正常的application.yml文件是绿色树叶的图标。
