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>

Answer 3

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

Answer 4

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,
"spring-cloud": {
"Edgware.SR5": "Spring Boot >=1.5.0.RELEASE and <=1.5.19.RELEASE",
