ABOUT

VRaptor uses XStream to serialize JSON from controllers, we don't like XStream because it serializes java.util.Map like this:

{"map": [
  [
    "key",
    "value"
  ]
]}

Instead of:

{"key":"value"}

I've tried to use git://github.com/luizsignorelli/vraptor-gson-serializer.git, but it doesn't serialize HypermediaResources' links. And, it uses an Annotation to set support. So, I write this one.

INSTALATION

git clone git@github.com:acdesouza/vraptor-gson-plugin.git
cd vraptor-gson-serializer
mvn install

CONFIGURATION

1. Add the dependency to your, maven, project:

    <dependency>
        <groupId>br.com.caelum.vraptor-contrib</groupId>
        <artifactId>vraptor-gson-plugin</artifactId>
        <version>0.1.0</version>
    </dependency>
   

2. Add this to your web.xml:

    <!-- To enable it with Restfulie -->
    <context-param>
      	<param-name>br.com.caelum.vraptor.packages</param-name>
      	<param-value>br.com.caelum.vraptor.restfulie,br.com.beyondclick.vraptor</param-value>
    </context-param>
   

Or

    <!-- To enable it with Restfulie -->
    <context-param>
      	<param-name>br.com.caelum.vraptor.packages</param-name>
      	<param-value>br.com.beyondclick.vraptor</param-value>
    </context-param>

USAGE

Nothing special about using it. Just plain old VRaptor way ;)

@Resource @Path("/customer")
public class CustomerController {

    private final Customers customers;
    private final Result result;

    public CustomerController(Customers customers, Result result) {
        this.customers = customers;
        this.result = result;
    }

    @Get("/{name}")
    public void findByName(String name){
        return result.use(representation()).from(Arrays.asList(customers.findByName(name))).recursive().serialize();
    }
}

So you can access this resource, from terminal, using:

curl -i 'http://localhost:8080/app/customer/antonio' -H 'Accept: application/json'
