我正在尝试创建一个image / jpeg jax-rs提供程序类,为我的基于帖子休息的Web服务创建一个Image。我无法制定请求以测试下面的内容,测试此内容的最简单方法是什么?
@POST
@Path("/upload")
@Consumes("image/jpeg")
public Response createImage(Image image)
{
image.toString(); //temp code here just to see if service gets hit
return null;
}
import java.awt.Image;
import java.io.IOException;
import java.io.InputStream;
import java.lang.annotation.Annotation;
import java.lang.reflect.Type;
import javax.imageio.ImageIO;
import javax.ws.rs.Consumes;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.MultivaluedMap;
import javax.ws.rs.ext.MessageBodyReader;
import javax.ws.rs.ext.Provider;
import org.springframework.stereotype.Component;
@Provider
@Consumes("image/jpeg")
@Component("ImageProvider") //spring way to register resource
class ImageProvider implements MessageBodyReader<Image> {
public Image readFrom(Class<Image> type,
Type genericType,
Annotation[] annotations,
MediaType mediaType,
MultivaluedMap<String, String> httpHeaders,
InputStream entityStream) throws IOException,
WebApplicationException {
Image originalImage = ImageIO.read(entityStream);
return originalImage;
}
public boolean isReadable(Class<?> arg0, Type arg1, Annotation[] arg2, MediaType arg3) {
throw new UnsupportedOperationException("Not supported yet.");
}
}
答案 0 :(得分:3)
如果您的提供商也实现了MessageBodyWriter,您可以使用客户端库(例如Wink Client)并使用相同的提供程序来发送图像:
Wink示例代码:
ClientConfig config = new ClientConfig();
Application application = // create application that contains ImageProvider
config.applications(application);
RestClient restClient = new RestClient(config);
URI uri = // uri to server
Image image = // create image
restClient.resource(uri).contentType("image/jpeg").post(image);
顺便说一句,您的提供程序中存在一个错误:您必须实现isReadable
方法,因此它将返回true
以获取正确的媒体类型和类。
