Spring Java Config vs Jboss 7

I was using @SpringBootApplication

As I read in this thread I needed to:

Change the mapping of the DispatcherServlet to "/*" instead of "/" (by adding a @Bean of type ServletRegistrationBean with a servlet named "dispatcherServlet")

In this url I found the code solution: Add Servlet Mapping to dispatch servlet

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

    @Bean
    public DispatcherServlet dispatcherServlet() {
        return new DispatcherServlet();
    }

    /**
     * Register dispatcherServlet programmatically 
     * 
     * @return ServletRegistrationBean
     */
    @Bean
    public ServletRegistrationBean dispatcherServletRegistration() {
        ServletRegistrationBean registration = new ServletRegistrationBean(
                dispatcherServlet(), "/*");
        registration
                .setName(DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_REGISTRATION_BEAN_NAME);
        return registration;
    }

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

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

}

I had a similar problem with a Spring MVC project deployed to JBoss 7.1 with no web.xml.

According to Spring javadocs for WebApplicationInitializer, older versions of Tomcat (<=7.0.14) could not be mapped to "/" programmatically. Older versions of JBoss AS 7 have this same defect.

This was the source of my problem. I was registering the servlet via "/", but JBoss EAP 6.4 doesn't support this mapping programmatically. It only works via web.xml. I still wanted to use programmatic config, so I changed the mapping to "/*" instead of "/", and it fixed my issue.

public class WebApplicationInitializerImpl implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext container) throws ServletException {
        WebApplicationContext context = getContext();

        Dynamic registration = container.addServlet("dispatcher", new DispatcherServlet(context));
        registration.setLoadOnStartup(1);
        registration.addMapping("/*");
    }

    private WebApplicationContext getContext() {
        AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
        context.setConfigLocation(AppConfig.class.getName());
        return context;
    }

}

Note: This configuration is incompatible with JSP views. "/*" will supersede the servlet container's JSP Servlet. If you still rely on JSP views, I would recommend using web.xml to configure the DispatcherServlet instead of doing it programmatically; the web.xml configuration works with "/" correctly.

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value></param-value>
    </init-param>
</servlet>

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
