For running the Spring web-application as Maven project, I need to add spring-boot-starter-tomcat as dependency in pom.xml. But for gradle project it is not required in build.gradle. Why is that so? I am running both in Intellij.
Running the Spring web-application as Maven project, if scope is specified as 'provided' in spring-boot-starter-tomcat dependency, the application starts without error and just ends. I need to comment scope 'provided' to run continuously as server. This is the console output on scope 'provided':

CodePudding user response:
I don't think you need a tomcat starter here:
You already have
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
By default it plugs the embedded tomcat and spring MVC so no need to other dependencies
Open Spring Initializr project and create a sample project, specify the webmvc and see what does it produce...
