13. Version 8: Porting the application to a Spring / Tomcat environment

Question: Following the example "Sample Application – 02: rdvmedecins-jsf2-spring" from [ref3], port the previous application to a Spring/Tomcat/Hibernate environment.

  

The new web application is [mv-pam-jsf2-spring-multipages]. The web interface remains unchanged:

Here is one possible approach:

  • create a Maven project of type [Java Application] named [mv-pam-spring-metier],
  • add the necessary dependencies,
  • copy the elements from the previous EJB project into the new Spring project,
  • fix any errors that appear in the Spring project,
  • create the [persistence.xml] file that configures the JPA layer,
  • create the Spring configuration file. At this point, the [mv-pam-spring-metier] project should be correct. Imagine a JUnit test that proves this,
  • create a Maven project of type [Web Application],
  • add the necessary dependencies (JSF and the [business] layer),
  • copy the elements from the JSF/EJB project of the previous version into the new JSF/Spring project,
  • fix any errors that appear,
  • copy the Spring configuration file from the [mv-pam-spring-metier] project into the web project,
  • add the code to the [ApplicationData] bean to instantiate the Spring beans,
  • complete the [faces-config.xml] configuration file,
  • Test the web application.
