Failed to start component [StandardEngine[Tomcat].StandardHost[localhost].TomcatEmbeddedContext[]]

Question

I am trying to build a SpringBoot application.

 import org.springframework.boot.SpringApplication;
 import org.springframework.boot.autoconfigure.SpringBootAppli         


        

Answer 1

My guess is you have to use the default ServletInitializer class that is provided within the Spring Boot Project template of Eclipse.

//SpringBootApplication.java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringBootApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootApplication.class, args);
    }
}

//ServletInitializer.java
public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringBootApplication.class);
    }

}

If you are not using ServletInitializer class as specified in Spring Boot Starter Project template, try to extend SpringBootServletInitializer from your App class

public class App extends SpringBootServletInitializer
