由于SpringCloud的运行需要依赖SpringBoot,之前SpringBoot版本采用的是1.5.9.RELEASE版,SpringCloud采用的是Camden.SR5版,可以完美配合.今天突然把SpringBoot升级到2.0.3,然后SpringCloud版本还是Camden.SR5版本,如果报了如下异常:

NoSuchMethodError: org.springframework.boot.builder.SpringApplicationBuilder.<init>([Ljava/lang/Obje

原因就是因为SpringBoot和SpringCloud版本不匹配,SpringBoot2.0.3版本,对应的SpringCloud的版本可以用Finchley.RELEASE版.

查看官网目前最新的​​Finchley​​​版本是​​Finchley.M8​​​，所以对于使用Spring Boot2.0.x的朋友，需要将对应的Spring Cloud切换为​​Finchley.M8​​​版本，即可解决​​SpringApplicationBuilder.<init>报出NoSuchMethodError​​的问题。下面给出大家一个spring boot版本和spring cloud版本的匹配关系：

需要按照上述表格做Spring boot和Spring cloud的关系匹配,就不会出现该错误了.
