Я пытаюсь настроить службу Restful на основе Spring Integration. Я пытаюсь избежать создания отдельных объектов для запроса и ответа, но вместо этого использую HashMap для простых функций, таких как isUserAvailableForRegistration при обслуживании.
* 1005 например *
HashMap<String, String> isUserAvailableForRegistration(HashMap<String,String> request)
Ниже приведена информация о контексте, связанная с интеграцией:
<bean class="org.springframework.integration.http.inbound.UriPathHandlerMapping"/>
<int-http:inbound-gateway id="inboundGateway"
request-channel="incoming" reply-channel="outgoing"
supported-methods="POST" reply-timeout="5000"
path="/customer/isUserAvailable" />
<int:channel id="incoming" />
<int:channel id="outgoing" />
<int:service-activator id="activator" input-channel="incoming" ref="customerManagementGateway"
method="isUserAvailableForRegistration" output-channel="outgoing" requires-reply="true" />
<int:object-to-json-transformer id="outgoingJsonConverter"
input-channel="outgoing" />
<int:json-to-object-transformer id="incomingJsonConverter" input-channel="incoming" type="java.util.HashMap" />
Несмотря на то, что я могу успешно проверить, что смог успешно выполнить маршаллинг HashMap в JSON, мне не хватает конфигурации для демаршаллизации данных JSON в HashMap.
Я получаю следующее исключение:

Кто-нибудь может мне помочь разобраться, что может быть не так?
Я дважды проверил заголовки, поэтому я уверен, что это что-то с конфигурацией или поддержкой Джексона для демаршаллинга в HashMap. Спасибо за ваше время.
