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.

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>

It is due to depricated dependency in spring-boot. Use following dependency

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

Please find initial working code

it does not help fix the problem – DrB Jun 17 '19 at 17:15
It worked for me can you check suitable dependency from url: (https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-dependencies) based on usage or compatibility with yours code. Otherwise clone working initial code (https://github.com/ravindra-yadava/zuul/), if still in problem please update i will try to help. – Ravindra Yadav Jun 19 '19 at 08:01

Using the Spring Start site, it looks like the correct Spring Cloud Version for Spring Boot 1.5 is:

Edgware.SR5 for Spring Boot >=1.5.0.RELEASE and <=1.5.19.RELEASE and
Edgware.BUILD-SNAPSHOT for Spring Boot >=1.5.999.BUILD-SNAPSHOT and <2.0.0.M1

The full output from the Spring Starter Actuator Info page,
