2021-04-09 为何分布式的运行结果和站长给的单体项目的运行结果不同呢?
不甘堕落




根据教程敲的分布式项目的运行结果和站长给的单体项目的运行结果不同; 具体表现看截图喽,因为主要是借着这个项目了解一下理财业务,技术因为是在2021年了,这个第一代的springCloud用的依然多,但不是主流 , 所以主要冲着业务来的,结果发现业务不对,望站长大大不畏艰苦,排查一下

嗯?不会吧,都是用的我的代码吗?

答案 或者 代码至少填写一项, 如果是自己有问题,请重新提问,否则站长有可能看不到

感觉项目到后面越做越容易,也许对这领域的概念不懂,弄懂之后,把MA均线做完,就后面的基本service逻辑都能清晰理解。站长的排版还是很好的,假如站长能出个用ui组件的项目就好了,用原生的前端我还是写得很难受
