无法找到内容类型MessageBodyReader /html和类型接口java.util.List
提问于 2017-10-31 16:51:42
请不要认为这是重复的要求，因为我已经通过了所有的堆叠溢出的帖子，他们都没有回答。我没有找到任何回应。
问题是：
我面临一个非常奇怪的问题，通过独立的应用程序(在main()中)使用相同的代码发出GET请求。如果将相同的代码放入Java应用程序并部署在通配符10服务器上，则会产生错误。
“无法找到内容类型的MessageBodyReader /html和类型接口java.util.List”
代码：
ClientConfig configuration = new ClientConfig();
configuration.property(ClientProperties.CONNECT_TIMEOUT, 10000);
configuration.property(ClientProperties.READ_TIMEOUT, 10000);
Client iexRestClient=ClientBuilder.newClient(configuration);
WebTarget webTarget =
iexRestClient.target("https://api.iextrading.com/1.0/ref-data/symbols/");
Response response =
webTarget.request().accept(MediaType.APPLICATION_JSON).get(Response.class);
System.out.println("response status "+response.getStatus());
List<IEXTicker> tickers = response.readEntity(new
GenericType<List<IEXTicker>>(){});
System.out.println("size of tickers "+tickers.size());必需的jars(pom.xml文件)

我也有同样的问题。它是由服务器引起的，服务器没有像预期的那样返回一个内容类型: application/json，但是它返回了：
content-type: text/html; charset=UTF-8我认为有两种选择：
1)与服务提供商联系并要求返回应用程序/json
2)将请求的结果读取为字符串，并手动将其转换为对象。与此类似：
String jsonData = response.readEntity(String.class);
ObjectMapper mapper = new com.fasterxml.jackson.databind.ObjectMapper();
JsonNode jsonNode= mapper.readValue(jsonData, com.fasterxml.jackson.databind.JsonNode.class);现在，从jsonNode数据创建一个列表..。
