AsciiBlog on JavaEE MVC (JSR 371)

#asciidoc #javaee monday, may 25, 2015

The latest version of AsciiBlog now uses the Early Draft Release of the new JavaEE 8 MVC specification (JSR 371). This makes the integration of JSPs with action-based MVC even easier.

The pom.xml was changed to

...
<dependency>
  <groupId>com.oracle.ozark</groupId>
  <artifactId>ozark</artifactId>
  <version>1.0.0-m01</version>
</dependency>

to include Ozark, the RI of MVC.

Ozark relies on Jersey and should to be deployed on a Glassfish (nightly build).

Switching to JSR 371 really simplifies the usage of action-based MVC:

@Controller
public class EntriesController {

    @Inject
    EntriesStore entriesStore;

    @Inject
    Models models;

    @GET
    @Path("{entry}")
    public String getEntry(@PathParam("entry") final String entryName) {
        final Entry entry = entriesStore.getEntry(entryName);

        if (entry == null)
            return "notFound.jsp";

        models.put("entry", entry);
        return "entry.jsp";
    }
}

The EntriesController is returned as a JAX-RS subresource and therefore has no @Path annotation itself. As MVC is based on JAX-RS many features are included from this specification.
