I am getting this error when starting application

Answer 1

org.springframework.boot.context.embedded.ServletRegistrationBean was deprecated in spring-boot version 1.4 and its replacement, org.springframework.boot.web.servlet.ServletRegistrationBean, was introduced. The deprecated class was removed in spring-boot version 1.5. Something in your app or in one of its dependencies needs to be updated to use the replacement.

Answer 2

for spring-boot version 1.5.x use Dalston.RELEASE in place of Brixton.SR5 in your dependency config:

<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Dalston.RELEASE</version>
