Resteasy + Maven，REST调用返回Server 415响应代码

Question

我正在使用maven开发一个java项目，我想使用RESTeasy来构建RESTful Web服务。我写了一个测试来检查RESTeasy的功能，但我总是得到HTTP Error 415 Unsupported媒体类型。我认为问题是我没有将Content-Type标头定义为JSON所以它会变成kaput，但我不知道该怎么做。怎么办？

BoardingPassProxy.java：

package com.boardingpass.clients.rest;

import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;

import com.BoardingPassRequest;

public interface BoardingPassProxy {

@POST
@Produces("application/json")
@Consumes("application/json")
public Response getBoardingPassImage(BoardingPassRequest boardingPassRequest);

} 

BoardingPassService.java：

package com.boardingpass.clients.rest;

import org.jboss.resteasy.client.ProxyFactory;
import org.jboss.resteasy.plugins.providers.RegisterBuiltin;
import org.jboss.resteasy.spi.ResteasyProviderFactory;

public class BoardingPassService {

public BoardingPassService() {
    RegisterBuiltin.register(ResteasyProviderFactory.getInstance());
}

public BoardingPassProxy getProxy(String endpoint) {
        BoardingPassProxy proxy = ProxyFactory.create(BoardingPassProxy.class, endpoint);
        return proxy;
    }
}
