    报错原因:No fallback instance of type class org.springblade.resource.feign.ResourceClientFallBack found for feign client blade-resource

    idea的"Build Project"和"Rebuild Project"的区别在于, 前者只对idea"认为有改变的文件"重新编译, 后者对整个工程强制完全编译, 无论有没有变化. 平时用Build Project (Ctrl + F9)是基本够用的. 而这次, 涉及到的是注解里的内容改变, 必须Build > Rebuild Project才能把这个变化纳入进来. 所以, 用Rebuild Project能解决这个问题.
