JAX-RS Moshi JSON Handlers

A message body reader/writer and parameter converter which uses Moshi to handle JSON.

Usage

ResourceConfig resourceConfig = new ResourceConfig();

Moshi moshi = new Moshi.Builder().build();

// Handles any request body marked as consuming application/json.
resourceConfig.register(new MoshiMessageBodyReader(moshi));
// Handles any response body marked as producing application/json.
resourceConfig.register(new MoshiMessageBodyWriter(moshi));
// Handles any parameter annotated with @Json.
resourceConfig.register(new MoshiParamConverterFactory(moshi));

(This example uses Jersey, but any JAX-RS-compatible implementation will work.)

The message body converters allow JSON serialization for request and response bodies:

@POST @Path("register") //
@Consumes(MediaType.APPLICATION_JSON) //
@Produces(MediaType.APPLICATION_JSON) //
public RegisterResponse register(RegisterRequest registerRequest) {
  // ...
}

The parameter converter allow JSON serialization for @Json-annotated parameters.

@POST @Path("checkin") //
@Consumes(MediaType.APPLICATION_FORM_URLENCODED) //
@Produces(MediaType.APPLICATION_JSON) //
public CheckinResponse checkin( //
    @FormParam("user") @Json User user) {
  // ...
}
