Property defined using "server.context-parameters.*" doesn't work on Java EE server

Question

We've generated a basic Spring Boot application to test some features.

I've prepared it to be deployed on an embedded server and on Java EE servers (Tomcat 7 and JBoss EAP 6.2) without applying any changes.

I've included server.context-parameters.* property on application.properties file.

If I deploy the application on an embedded server using java -jar or mvn spring-boot:run, it's working without problems. But, If I deploy the same application on Tomcat 7 or JBoss EAP 6.2, I'm not able to load the context-params correctly.

• Which is the correct way to define context parameters on Spring Boot application deployed on Java EE container without use web.xml file?

Answer 1

Finally, I found the following solution thanks to Stéphane Nicoll

server.context-parameters.* only works for embedded servers, so to configure context-parameters on Java EE server is necessary to include a @Bean of type ServletContextInitializer like the following:

@Bean
public ServletContextInitializer contextInitializer() {
    return new ServletContextInitializer() {

        @Override
        public void onStartup(ServletContext servletContext)
                throws ServletException {
                servletContext.setInitParameter("dummy.type","on-context-parameters");
        }
    };
}
