IntelliJ Process finished with exit code 0 when spring-boot run

I have a problem when starting spring-boot appication from IntelliJ-Idea. I don't have this problem when running application through terminal.

:: Spring Boot ::        (v1.2.1.RELEASE)

2015-09-24 12:22:44.274  WARN 22380 --- [           main] n.sf.ehcache.config.CacheConfiguration   : Cache 'publicationsCount' is set to eternal but also has TTI/TTL set.  To avoid this warning, clean up the config removing conflicting values of eternal, TTI and TTL. Effective configuration for Cache 'publicationsCount' will be eternal='true', timeToIdleSeconds='0', timeToLiveSeconds='0'.

Process finished with exit code 0

I think this warn is not causing it. What may be the reason?

Deleting provided scope of spring-boot-starter-tomcat dependency helps me.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>

I create a simple project from https://start.spring.io/ (sprint initializr) and added a simple controller to run the application.

@RestController
public class testController {

    @GetMapping(value="/")
    //@RequestMapping(value="/",method=RequestMethod.GET)
    public String hello(){
        return "Hello World!!";
    }
}

but it wasn't getting started because my pom wasn't having

<dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-web</artifactId>
</dependency>

After adding this my application started...

Adding spring boot starter web solved my problem

    <dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-web</artifactId>
	</dependency>

Add the below dependencies in pom.xml :

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <scope>test</scope>
        </dependency>

If you create a project gradle template from https://start.spring.io/ (sprint initializr), you need to add org.springframework.boot:spring-boot-starter-web dependecy in you build.gradle file.

// you need to add this dependency to run spring boot correctly
implementation 'org.springframework.boot:spring-boot-starter-web' 	

in my case i started intelliJ as

> adminstrator

, then it works make sure you have tomcat dependency

 <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-core</artifactId>
        <version>9.0.29</version>
    </dependency>

Using the below dependencies in pom.xml, as well as loading maven changes (ctrl+shift+o) solved my problem.

<dependencies>
	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-web</artifactId>
	</dependency>

	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-tomcat</artifactId>
	</dependency>

	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-test</artifactId>
		<scope>test</scope>
	</dependency>
</dependencies>

In my case, there is a slight difference between:

• Just click Run in the most visible bottom inside IntelliJ and...
• Look for the default controller inside src/main/java/com.exampler.yourapplication, right click and press Run there.

The second option just run the project properly.

If below property was added to the allication.properties file, need to remove this. This property is used to remove the web container.

spring.main.web-application-type=none

In my case I forgot to remove this and once it's removed the issue was fixed
