Trying to brushup on my j2ee so downloaded a Spring initializr zipped folder and imported in IntelliJ.
I am getting below error while trying to run it as Java Application.

Any clues?
Given that your project is just generated from spring initializer it doesn't really do anything yet, and you'll have to add some functionality for it to not exit immediately.
If you expect it to start as a webapp you'll have to add a dependency on spring-boot-starter-web.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
If you prefer tomcat as your container, you're good to go with the above dependency, but if you prefer something else - like jetty you'll have to exclude tomcat from spring-boot-starter-web
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jetty</artifactId>
</dependency>
Then you'll get something close to this when starting running DemoApplication
