SpringCloud异常(Euruka)：Application run failed java.lang.NoSuchMethodError: org.springframework.boot.b

问题：SpringCloud异常(Euruka)：java.lang.NoSuchMethodError: org.springframework.boot.builder.SpringApplicationBuilder.<init>([Ljava/lang/Object;)V

问题原因：jar包冲突，以下是我的pom文件

可以发现SpingBoot 使用的是2.0.1版本。

解决方式一：将Spring Boot的版本修改为1.4.0版本即可解决问题。

解决方式二：继续使用2.0.1版本的Spring Boot,然后删掉 spring-boot-starter-web包，也可以解决问题（猜测应该是2.0.1版本的spring-boot-starter-parent包，已经包含了spring-boot-starter-web包，于是与pom中再次引入的web包发生冲突，欢迎大神沟通交流）
