我正在使用readEntity()
方法读取JAVAX响应,但正在跟踪stacktrace:
java.lang.IllegalStateException: Entity input stream has already been closed.
at org.glassfish.jersey.message.internal.EntityInputStream.ensureNotClosed(EntityInputStream.java:225) ~[jersey-common.jar:?]
at org.glassfish.jersey.message.internal.InboundMessageContext.readEntity(InboundMessageContext.java:832) ~[jersey-common.jar:?]
at org.glassfish.jersey.message.internal.InboundMessageContext.readEntity(InboundMessageContext.java:785) ~[jersey-common.jar:?]
在线
Map<String, Map> mapEntityFromResponse = res.readEntity(Map.class);
这是我的代码
public Output getClaimsFromAPI(@NonNull final Input xyzInput)
throws PermanentException, TransientException {
final Response res = fetchHealBeamServiceResponse(webTarget, xyzInput);
Object respondentMapObject;
Map<String, Map> mapEntityFromResponse = res.readEntity(Map.class);
if (mapEntityFromResponse != null) {
respondentMapObject = mapEntityFromResponse.get(ServiceConstants.MAP_KEY);
return getOutputFromResponseMap(respondentMapObject, xyzInput);
} else {
throw new RuntimeException("The response returned does not contain map");
}
}
private Response fetchHealBeamServiceResponse(WebTarget healBeamTarget,
Input xyzInput)
throws PermanentException, TransientException {
Response res = null;
try {
res = healBeamTarget
.path(HealBeamServiceConstants.GET_CUSTOMER_PATH)
.register(Configurator.getSoaOpNameFeatureForCustomerResource())
.resolveTemplate(ServiceConstants.ID, xyzInput.getId())
.request(MediaType.APPLICATION_JSON_TYPE)
.property(HealBeamServiceConstants.SERVICE_KEY, SOA_SERVICE_NAME)
.property(HealBeamServiceConstants.OPERATION_KEY, SOA_OP_NAME_GET_CUSTOMER)
.acceptLanguage(java.util.Locale.getDefault())
.get();
if (Response.Status.REQUEST_TIMEOUT.getStatusCode() == res.getStatusInfo().getStatusCode()) {
throw new TransientException("Request timed out with status" + res.getStatusInfo().getStatusCode());
} else if (Response.Status.OK.getStatusCode() != res.getStatusInfo().getStatusCode()) {
log.error("Some Error"):
}
return res;
} catch (RuntimeException e) {
throw new PermanentException("Unexpected Exception Occured, Exception Message " + e.getMessage());
} finally {
if (res != null) {
res.close();
}
}
}
您最终会在返回响应之前立即关闭响应,这就是为什么无法在调用方法getClaimsFromAPI()中读取响应的原因。只是为了说明一下:您认为下面发布的main()方法会打印什么?
public class NewApp {
public static void main(String[] args) {
Person p = demonstrate();
System.out.println(p.name);
}
public static Person demonstrate(){
Person person = new Person();
try {
person.name = "name set in try";
return person;
} catch (Exception ex) {
throw ex;
} finally {
person.name = "name set in finally";
}
}
}
class Person {
public String name;
}
