Spring Cloud Config Client - Angel.SR4 vs Boot 1.3.1？

Question

全部，

我以前用Spring Cloud/Spring Boot的早期版本構建了Spring Cloud Config服務器和客戶端，但我似乎遇到了Angel.SR4/Boot 1.3.1組合的問題。

繼這裏的基本指令（http://projects.spring.io/spring-cloud/docs/1.0.3/spring-cloud.html#_client_side_usage），但是使用了引導和雲（1.3.1.RELEASE/Angel.SR4目前）的當前版本，我得到以下堆棧跟蹤：

如果我將Boot版本退回到1.2.8，則問題消失。如果我將Cloud移動到Brixton.M4，問題就會消失。是否有應該一起使用的Boot/Cloud的規定版本組合？提前致謝。

Answer 1

是否有應一起使用開機/雲的規定版本的組合？

是。天使是引導1.2，布里克斯頓是引導1.3。查看博客瞭解更多詳情：https://spring.io/blog/2015/11/25/migrating-spring-cloud-apps-from-spring-boot-1-2-to-1-3
