Answer 1

I don't see anything glaringly wrong with what you have. I have an app that I deploy both as a jar and war simultaneously in different environments (they differ only by packaging); I have a ServletInitializer equivalent to yours and it works without issue with one primary difference.

I use a maven run configuration with spring-boot:run as the "Command line" value. With that I can do no more than change the pom to reflect jar or war, run, and go. I've faced problems when switching back and forth and using a config that invokes main in the app class. For example, just for fun I just ran an instance of the app with jar packaging and running main . Wouldn't even launch. This is just after having it jar packaged and launched using the maven config I mentioned above.

I would recommend starting with creating that maven run configuration and see what the results are. Here's the way to do it in Intellij so you don't have to use the command line interface.

1. Choose "Edit configurations..." from the dropdown next to the play button.
2. Press the green + in the upper left-hand corner.
3. Choose to create a maven configuration.
4. Name it.
5. Add spring-boot:run to the "Command line" entry.
6. Optionally, make it "Share"d or "Single instance only".

I'm not an eclipse/sts user but I'm sure there's a similar way to do it.

Answer 2

Although an answer has been accepted, still this might help:

Are you trying to run the application from Intellij from Run menu or by right click and run on the class where your main is defined and you are getting above issue and the application works fine from command line?

If above is the case, I see your pom.xml have dependency with provided scope.

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

When running the application from run menu in intellij, dependencies with provided scope are not available by default.

To fix this,

Go to Run Menu -> Edit Configuations and then select Include dependencies with provided scope

Image for reference:

And try to run again. This should fix the issue.

Good luck.

Answer 3

Apparently, you're going to package your application as war , that's fine but the problem is that you're running your application through the main method in InternetMovieDatabaseApplication class. Instead, you should either deploy your application to a Standalone Servlet Container , like Tomcat or Jetty , or run the application using the mvn spring-boot:run command.

If packaging your application as war archive is not a strict requirement, i recommend to make jar, not war . In order to doing so, first remove the packaging in your pom.xml :

<packaging>war</packaging>

Then remove the spring-boot-starter-tomcat dependency:

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

And finally remove the ServletInitializer class and run the main method in your InternetMovieDatabaseApplication class.

Answer 4

I don't think you need your ServletInitializer

your InternetMovieDatabaseApplication with the @SpringBootApplication annotation should be sufficient.

Answer 5

I was having this problem, it was fixed by removing this dependency:

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>4.1.6.RELEASE</version>
    </dependency>

Answer 6

I think you forgot add main-class in properties your pom.xml

<properties>
    <start-class>org.infoowl.InternetMovieDatabaseApplication</start-class>
    <java.version>1.8</java.version>
</properties>

and modify your class as follow:

@SpringBootApplication
public class InternetMovieDatabaseApplication extends SpringBootServletInitializer {
   @Override
   protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
      return application.sources(DemoApplication.class);
   }
    public static void main(String[] args) {
        SpringApplication.run(InternetMovieDatabaseApplication.class, args);
    }
}

and open a command console, execute:

mvn clean package

then, deploy war into Tomcat, demo here
