27. Spring 4 vs Java EE 7 Spring 4, Java EE 7 or Both? @ivar_grimstad
28. Application based on Spring 4 Spring 4, Java EE 7 or Both? @ivar_grimstad
29. Application based on Java EE 7 Spring 4, Java EE 7 or Both? @ivar_grimstad
30. Application based on Both Spring 4, Java EE 7 or Both? @ivar_grimstad
31. Spring 4, Java EE 7 or Both? @ivar_grimstad DEMO !
32. • Spring 4 application configuration • Java EE 7 application configuration • Combine the two approaches • Examine portability across application servers – WildFly – Glassfish – Tomcat Demo Contents Spring 4, Java EE 7 or Both? @ivar_grimstad
33. Spring 4 - Configuration Spring 4, Java EE 7 or Both? @ivar_grimstad @Configuration @ComponentScan("eu.agilejava.spring4") @EnableWebMvc public class ApplicationConfig extends WebMvcConfigurerAdapter { }
34. Java EE 7 - Configuration Spring 4, Java EE 7 or Both? @ivar_grimstad @ApplicationPath("api") public class ApplicationConfig extends Application {
35. Spring 4 + Java EE 7 - Configuration Spring 4, Java EE 7 or Both? @ivar_grimstad @Configuration @ComponentScan("eu.agilejava.both") @ApplicationPath("api") public class ApplicationConfig extends Application { }
36. • No configuration changes • No code changes • New dependency (pom.xml) Spring 4 - Portability Spring 4, Java EE 7 or Both? @ivar_grimstad
37. • Minor configuration changes • No code changes • No new dependencies (pom.xml) Java EE 7 - Portability Spring 4, Java EE 7 or Both? @ivar_grimstad
38. • Configuration changes • No code changes • New dependencies (pom.xml) Spring 4 + Java EE 7 - Portability Spring 4, Java EE 7 or Both? @ivar_grimstad
39. • Spring 4 is more portable • Even across Java EE 7 app servers • Java EE 7 requires less configuration • And fewer dependencies Conclusion Spring 4, Java EE 7 or Both? @ivar_grimstad
