Spring integration Spring集成：无法解决'；json_uuuutypeid_uuuu'；在'；javaTypes'；

在我发送请求消息并获取有效负载数据（json）后，我想从gitlab应用程序中获取json数据，我使用postman chrome插件附加了内容

我得到的错误如下

Caused by: java.lang.IllegalArgumentException: Could not resolve 'json__TypeId__' in 'javaTypes'.

我的spring集成程序如下所示。我提到了这个问题。我从标头收到的标头中没有标头值

<int-http:outbound-gateway 
        id="http-outbound-gateway"
        auto-startup="true" 
        http-method="GET" 
        charset="UTF-8"
        request-channel="redca-gitlab-request-prepare-channel"
        reply-channel="redca-hub-gitlab-response-channel"
        url="{gitlab.url}{gitlab.data.type}?private_token={gitlab.private.token}">
         <int-http:uri-variable name="gitlab.url" expression="headers['gitlab.url']"/>  
         <int-http:uri-variable name="gitlab.data.type" expression="headers['gitlab.data.type']"/>
         <int-http:uri-variable name="gitlab.private.token" expression="headers['gitlab.private.token']"/>
    </int-http:outbound-gateway> 

    <int:chain input-channel="redca-hub-gitlab-response-channel"  output-channel="redca-output-channel">
        <int:header-enricher>
            <int:header name="json__TypeId__" expression="headers['x-json__TypeId__']" />
        </int:header-enricher>
        <int:json-to-object-transformer object-mapper="mapper"></int:json-to-object-transformer>
    </int:chain>



    <bean id="mapper" class="org.springframework.integration.support.json.Jackson2JsonObjectMapper">
</bean>

我没有看到

x-json\uuuuuu TypeId\uuuuu

头-链接的问题是与Spring Integration HTTP服务器对话并传送头，而不是与某些外部HTTP服务对话

由于没有标题，因此需要告诉

您希望将对象转换为什么

<json-to-object-converter type="java.util.HashMap" />

（或某些域对象，如果已设置jackson映射）

<json-to-object-converter type="java.util.HashMap" />
