小编use*_*803的帖子

我正在使用带有jackson提供程序的RestEasy客户端并收到上述错误

客户端代码是:

ClientRequest request = new ClientRequest(url);
request.accept(MediaType.APPLICATION_JSON);
ClientResponse<String> response = request.get(String.class);

if (response.getStatus() != 200) {
  throw new RuntimeException("Failed : HTTP error code : " + response.getStatus());
}

BufferedReader br =
  new BufferedReader(new InputStreamReader(new ByteArrayInputStream(response.getEntity().getBytes())));

response.getEntity()正在抛出ClientResponseFailure异常,错误是

Unable to find a MessageBodyReader of content-type application/json and type class java.lang.String

我的服务器端代码如下:

@GET
@Path("/{itemId}")
@Produces(MediaType.APPLICATION_JSON)
public String item(@PathParam("itemId") String itemId) {
  //custom code

  return gson.toJSON(object);
}
