I want to use RestTemplate/TestRestTemplate by including the artifact in a SpringBoot application
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> </dependency> But this automatically starts Tomcat or Jetty. Is there a way to turn it off, or by not including the above artifact. TestRestTemplate is in the boot artifact, but not the base RestTemplate.

If we want to exclude tomcat from spring boot, we don't need to do much, we just need to add one additional block(<exclusions>) to the Spring Boot dependency. <exclusions> tag is used to make us sure that given server/artifactId is being removed at the time of build.
73.11 Use Jetty instead of TomcatYou need to exclude those dependencies and include the Jetty one instead. Spring Boot provides Tomcat and Jetty dependencies bundled together as separate starters to help make this process as easy as possible. Example in Gradle: configurations { compile.
You will need to update pom. xml , add the dependency for spring-boot-starter-jetty . Also, you will need to exclude default added spring-boot-starter-tomcat dependency.
Spring Boot is not going to start a web container if it's not present. spring-web does not provide any embedded container. You may want to analyse the dependencies of your project (try mvn dependency:tree).
If you want to make sure a web server is not started in your spring boot application, you can set the following configuration key
spring.main.web-application-type=none Or you can use the SpringApplicationBuilder
new SpringApplicationBuilder(YourApp.class) .web(WebApplicationType.NONE).run(args); Since Spring Boot 2.0.0 this property is deprecated and following is the new way:
spring.main.web-application-type=none This change is because Spring Boot the support for reactive server.
