Answer 1

it doesn't have an embedded server like Tomcat in classpath. add it and it will fix the issue for MAVEN add this dependancy in pom.xml

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

for Gradle (build.gradle) add

dependencies {
    compile 'org.springframework.boot:spring-boot-starter-web'
}

Answer 2

You need to add this dependency to your pom.xml. After that it should work.

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