Spring boot war doesn´t work on Jboss 7.1

Question

I´m trying to deploy a Spring boot application on Jboss. I follow this tutorial for convert my jar in to a war file. But when i try to run the application on Jboss it´s give

Answer 1

spring-boot on compile generate two files(.war).

myapp-0.0.1-SNAPSHOT
myapp-0.0.1-SNAPSHOT.war.original

If you wan to deploy to JBoss 7.1 you need to rename myapp-0.0.1-SNAPSHOT.war.original to e.g myapp-0.0.1.war(remove .original extension) and deploy to server.

Answer 2

The main issue with deploying spring-boot is explained here

The post is a bit old by now and does not apply to the current spring-boot (1.3.3 as of this writing).

What is happening in your case is that some filter in spring-boot actuator do not have default constructors which JBoss will try to call so to get around this you need to do the following (This is for current spring-boot 1.3.3):

Create an ApplicationContext which will wrap all bean filters in a delegating class which has a default constructor. We can use spring's DelegatingFilterProxy for that

public class JBossWebApplicationContext extends AnnotationConfigEmbeddedWebApplicationContext {

private final Logger log = LoggerFactory.getLogger(getClass());

@Override
protected Collection<ServletContextInitializer> getServletContextInitializerBeans() {
    Collection<ServletContextInitializer> servletContextInitializerBeans = super.getServletContextInitializerBeans();
    for (ServletContextInitializer servletContextInitializerBean : servletContextInitializerBeans) {
        if (servletContextInitializerBean instanceof FilterRegistrationBean) {
            FilterRegistrationBean frb = (FilterRegistrationBean) servletContextInitializerBean;
            try {
                Field field = FilterRegistrationBean.class.getDeclaredField("filter");
                field.setAccessible(true);
                Filter origFilter = (Filter) field.get(frb);
                frb.setFilter(new DelegatingFilterProxy(origFilter));
            } catch (NoSuchFieldException | IllegalAccessException e) {
                throw new BeanCreationException("Error setting up bean. It does not have a filter field", e);
            }

        }
    }

    return servletContextInitializerBeans;
}
}

Then in your springboot main class make sure to use the context we created above:

@SpringBootApplication
public class MyApplication extends SpringBootServletInitializer {

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    application.sources(MyApplication.class);
    application.contextClass(JBossWebApplicationContext.class);
    return super.configure(application);
}

public static void main(String[] args) throws Exception {
    SpringApplication app = new SpringApplication(MyApplication.class);
    app.setApplicationContextClass(JBossWebApplicationContext.class);
    app.run(args);
}
}

Lastly you need to make sure your servlet path is configured to be "/*" since JBoss 7.1 does not seem to work with only the default (/). This can be configured in your application.yml (or application.properties)

server:
  servletPath: /*

This should allow you to deploy a springBoot application in JBoss 7.1 (Tested myself on 7.1.3)

Some extra points:

• I have NOT tested this extensively and therefore you should make sure things are behaving as they should be before relying on this solution
• I really don't like having to call reflection to get the FRB underlying filter but unfortunately the getFilter method is protected
• This solution can probably be improved upon by someone who is more versed into spring than I am
