找不到非具体集合类型的解串器

Question

我正在尝试通过“ response.readEntity（JsonArray.class）;”获得输入我遇到错误的地方-“ com.fasterxml.jackson.databind.JsonMappingException：找不到非具体Collection类型的反序列化器”。

import javax.json.JsonArray;
HostnameVerifier hostnameVerifier =  HttpsURLConnection.getDefaultHostnameVerifier();

SSLContext ctx = SSLContext.getInstance("SSL");
ctx.init(null, certs, new SecureRandom());
client = ClientBuilder.newBuilder().withConfig(new ClientConfig())
     .hostnameVerifier(hostnameVerifier).sslContext(ctx).build();
static WebTarget target;
Response response = getResponsebyURI(uri);
target = client.target(URI);
Response res = target.request(MediaType.APPLICATION_JSON).header("key", value).get();
JsonArray j = null;
j = response.readEntity(JsonArray.class);

请帮助我解决异常并阅读输入内容。
