Getting error running spring boot application using -jar - spring

Question

This question has been asked over and over, however I couldn't find my answer. I have an application using spring boot, which intellij can run it without any issue, however java -jar echohostname.jar give me this error:
Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean
Here is my Main class:
public class ApplicationMain {
public static void main(String[] args) {
SpringApplicationBuilder builder = new SpringApplicationBuilder(SpringConfiguration.class);
ConfigurableApplicationContext applicationContext = builder.run(args);
}
This is my Controller class:
#RestController
public class Controller {
#Autowired
#Qualifier("getSigarProxy")
private SigarProxy sigarProxy;
#RequestMapping(value = "/hostname", method = RequestMethod.GET)
public String hostName() throws SigarException {
return "HELLO THERE";
//return sigarProxy.getNetInfo().getHostName();
}
}
And this is spring configuration class:
#SpringBootApplication
#Configuration
#ComponentScan("controller")
public class SpringConfiguration {
#Bean
public static PropertySourcesPlaceholderConfigurer getPropertySourcesPlaceholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
#Bean
public Sigar getSigar() {
return new Sigar();
}
#Bean
public SigarProxy getSigarProxy() {
return SigarProxyCache.newInstance(getSigar(), 1000);
}
#Bean
#Scope("prototype")
public HttpHeaders getHttpHeaders() {
return new HttpHeaders();
}
#Bean
#Scope("prototype")
public AsyncRestTemplate getRestTemplate() {
return new AsyncRestTemplate();
}
}

Any help is appreciated.

Answer 1

Add class level #SpringBootApplication annotation in ApplicationMain.java
Add the below plugin in your pom.xml. Build the maven project and execute the jar command
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.6</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
This page has more information on maven assembly plugin - https://maven.apache.org/plugins/maven-assembly-plugin/usage.html

Answer 2

In a spring-boot project, you need that the parent pom be
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.2.7.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
You can remove the spring dependencies, like context, core and beans.
Add to the pom
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
And build the jar again.
