Building a flexible registration module

In this recipe, we will create a new registration module that will manage user registration and authentication requests. Creating a module for this allows us to reuse a very common workflow in the modern web application.

How to do it…

For Java, we need to perform the following steps:

Run the foo_java application with Hot-Reloading enabled:
```
    activator "~run"
```
Inside the modules directory, foo_java/modules, generate the registration module project using the activator:
```
    activator new registration play-java
```

Add the dependency between the root project, foo_java, and the module, registration, in foo_java/build.sbt:

    lazy val root = (project in file("."))
      .enablePlugins(PlayJava)
      .aggregate(filemon)
      .dependsOn(filemon)
      .aggregate(registration)
      .dependsOn(registration)

    lazy val filemon = (project in file("modules/filemon"))
      .enablePlugins(PlayJava)

    lazy val registration = (project in file("modules/registration...
