I am trying to run a sample Spring Boot Application provided here: https://spring.io/guides/gs/rest-service/
I want this to be built as a war, which then should automatically deploy to localhost using tomcat. I've done this once before, but I am unsure as to why it doesn't work now. Here is the error:

Here is the code for the simple classes provided by the tutorial:
GreetingController.java
package com.test.Components;
import java.util.concurrent.atomic.AtomicLong;
import com.test.Models.Greeting;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class GreetingController {
private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();
@RequestMapping("/greeting")
public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) {
return new Greeting(counter.incrementAndGet(),
String.format(template, name));
}
}
Greeting.java
package com.test.Models;
public class Greeting {
private final long id;
private final String content;
public Greeting(long id, String content) {
this.id = id;
this.content = content;
}
public long getId() {
return id;
}
public String getContent() {
return content;
}
}
I have modified the main class to look like this:
package com.test.Server;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
@SpringBootApplication
public class Application extends SpringBootServletInitializer{
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
}

I am truly at a loss as to why it does not work. I included the necessary dependencies for building the war and using tomcat, and I do a clean and install for maven each time I run it. My war is CORRECTLY output to the Target folder as well. My configuration simply looks like this:
I have already tried messing with the package structure and using scanBasePackages, but nothing changes the error.
Any help is GREATLY appreciated.
First change the start-class to your application class. Second add the super-cool Spring Boot maven builder to your pom. Then use "mvn install" to create your jar. Your code runs just fine.
Spring Boot SpringApplication class is used to bootstrap and launch a Spring application from a Java main method. This class automatically creates the ApplicationContext from the classpath, scan the configuration classes and launch the application.
Spring Boot Servlet Initializer class file allows you to configure the application when it is launched by using Servlet Container. The code for Spring Boot Application class file for JAR file deployment is given below − package com. tutorialspoint. demo; import org.
Spring Boot Auto Configuration automatically configures your Spring application based on the JAR dependencies you added in the project. For example, if MySQL database is on your class path, but you have not configured any database connection, then Spring Boot auto configures an in-memory database.
The solution is presented here https://stackoverflow.com/a/45263216/1937953
TLDR remove <scope>provided</scope>
from the dependency of spring-boot-starter-tomcat
in the pom.xml file
i think there is a misunderstanding here, in spring boot we don't need to create a war in order to deploy in tomcat server. The advantage of using spring boot is that it adds all the required dependencies. So you need to just develop the application
Here are the following steps you can try to make it work.
if you want your project to create a war file and deploy it in an external server you need to set your scope of the tomcat dependency in spring boot to "provided".
`<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>`
if you want your application to be deployed automatically after ruuning the spring boot application you set the scope to "compile".
`<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>`
