我需要調用返回一個API以下JSON格式,並將其轉換成Java對象:錯誤讀取從輸入流實體 - 利用傑克遜
GET /api/myimpl/?ids=5,12
HTTP 200 OK
Allow: GET, POST, HEAD, OPTIONS
Content-Type: application/json
Vary: Accept
[
{
"id": "A1",
"impl": "HeatSmart"
},
{
"id": "B2",
"impl": "My String"
}
]
我有下面的類:
public class QueryStrings {
private String id;
private String impl;
public QueryStrings() {
}
public QueryStrings(String id, String impl) {
this.id = id;
this.impl = impl;
}
public String getId() {
return id;
}
public String getImpl() {
return impl;
}
public void setId(String id) {
this.id = id;
}
public void setImpl(String impl) {
this.impl = impl;
}
}
在我的代碼,我做了以下內容:
client = ClientBuilder.newClient().register(JacksonFeature.class);
Response clientResponse = client.target(myURL)
.queryParam("ids", "5,12")
.request()
.accept(MediaType.APPLICATION_JSON_TYPE)
.get();
QueryStrings jsonResponse = clientResponse.readEntity(QueryStrings.class);
的clientResponse返回狀態OK。然而,當我試圖讓json進入我想要的對象時,最後一行返回錯誤:
javax.ws.rs.ProcessingException: Error reading entity from input stream.
我的代碼中缺少什麼?
使用
GenericType
我的理解,HTTP響應包含'QueryStrings'的陣列? –
