Spring Boot App Terminating at Startup

I am trying out a simple spring boot application it always shuts down automatically ``` :: Spring Boot :: (v1.4.1.RELEASE) 2016-10-23 13:05:21.681 INFO 16532 --- [ main] com.example.RestBootApplication : No active profile set, falling back to default profiles: default 2016-10-23 13:05:21.766 INFO 16532 --- [ main] s.c.a.AnnotationConfigApplicationContext : Refreshing org.springframework.context.annotation.AnnotationConfigApplicationContext@6e20b53a: startup date [Sun Oct 23 13:05:21 EDT 2016]; root of context hierarchy 2016-10-23 13:05:23.682 INFO 16532 --- [ main] o.s.j.e.a.AnnotationMBeanExporter : Registering beans for JMX exposure on startup 2016-10-23 13:05:23.704 INFO 16532 --- [ main] com.example.RestBootApplication : Started RestBootApplication in 2.632 seconds (JVM running for 5.168) 2016-10-23 13:05:23.705 INFO 16532 --- [ Thread-2] s.c.a.AnnotationConfigApplicationContext : Closing org.springframework.context.annotation.AnnotationConfigApplicationContext@6e20b53a: startup date [Sun Oct 23 13:05:21 EDT 2016]; root of context hierarchy 2016-10-23 13:05:23.708 INFO 16532 --- [ Thread-2] o.s.j.e.a.AnnotationMBeanExporter : Unregistering JMX-exposed beans on shutdown ``` pom.xml ``` <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.example</groupId> <artifactId>demo</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>rest-boot</name> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.1.RELEASE</version> <relativePath /> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project> ``` Main Class ``` @SpringBootApplication public class RestBootApplication { public static void main(String[] args) { SpringApplication.run(RestBootApplication.class, args); } } ``` Controller ``` @Controller public class HelloController { @RequestMapping("/hello") String helloWorld(){ return "helloWorld"; } } ``` Trying to run in spring tool suite. it always stops after starting. I even added "spring-boot-starter-web" after looking at some stackoverflow questions, but still facing the issue. Please can you someone point out the issue.
