Question

我尝试使用jackson将http json响应转换为java对象。

        webResource.accept("application/json");
        ClientResponse clientResponse = webResource.path("routingRequest")
                .queryParam("options", rr.options)
                .accept(MediaType.APPLICATION_JSON_TYPE)
                .get(ClientResponse.class);

        Response routingResponse = clientResponse.getEntity(Response.class);

但是我收到了这个错误：

A message body reader for Java class com.archive.Response, and Java type class com.archive.Response, and MIME media type text/x-json was not found

和

如何轻松定位错过匹配问题？

更新

我甚至试图忽略尽可能多的成员：

public class RoutingResponse {
    @JsonIgnore public Response response;
    @JsonIgnore public Coordinate[] coords;
    public Coordinate segCoords;
}

仍然无法解析JSON响应：

{
    "response": {
        "routeName": "המכבים, באר שבע",
        "results": [{
        }],
        "streetNames": ["ג'ו יוסף אלון", null, "הפלמ\"ח", "המכבים", "נגבה", "דבורה", "אהוד בן גרא"],
        "tileIds": [],

        "displayRoute": true
    },
    "coords": [{
        "x": 34.78103644431032,
        "y": 31.243934961900017,
        "z": NaN
    }, {
        "x": 34.779020165815155,
        "y": 31.242382384889336,
        "z": NaN
    }],
    "segCoords": null
}

Answer 1

原因是响应的媒体类型：text / x-json 它必须是＆＃34; application / json＆＃34;被你的图书馆接受。

未找到Java类com.archive.Response和Java类型类com.archive.Response以及MIME媒体类型text / x-json的消息正文阅读器
