Spring Boot does not honor @WebServlet

Question

I created a Servlet (extending from HttpServlet) and annotated as per 3.0 specs with

@WebServlet(name=\"DelegateServiceExporter\", urlPatterns={\"/remoting/Deleg         


        

Answer 1

Add @ServletComponentScan in your bootstrap class.

such as

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

This will enable spring boot to scan @WebServlet as well as @WebListener.

Answer 2

It's possible to load servlets annotated with @WebServlet and their mappings in Spring Boot. To do this you need to use @ServletComponentScan with @Configuration annotation. This also works for @WebFilter and @WebListener annotations.

Answer 3

With Spring Boot, you should use the ServletRegistrationBean object instead of the @WebServlet annotation if you want to register a Servlet and provide the URL pattern.

Adding this bean to your @Configuration class should do the trick :

@Bean
public ServletRegistrationBean delegateServiceExporterServlet() {
    return new ServletRegistrationBean(new DelegateServiceExporter(), "/remoting/DelegateService");
}
