java - Spring Integration AMQP - Wrong JSON type on Response -

-

i'm using spring integration & si amqp 3.0.0-release.

i have simple request-response on amqp between 2 si instances.

i'm finding when response arrives on requesting server, si attempting deserialize response using the request object's type, not response object.

ie., given gateway interface of:

public analyticsreponse getanalyticsreport(entitymessage objecturi);

i find though correct json of analyticsresponse arrives on server, si attempting deserialize entitymessage, failing.

i've debugged through, , suspect cause responding side copying inbound json__typeid__ header, rather supplying it's own. however, can't see i've misconfigured this.

here's config -- have done wrong?

requesting side:

<int:channel id="analytics.reports.requests.channel" />  <int:channel id="analytics.reports.responses.channel" /> <int:gateway service-interface="com.project.analytics.gateway.analyticsreportinggateway">     <int:method name="getanalyticsreport" request-channel="analytics.reports.requests.channel" reply-channel="analytics.reports.responses.channel"/> </int:gateway> <int-amqp:outbound-gateway      request-channel="analytics.reports.requests.channel"      reply-channel="analytics.reports.responses.channel"     exchange-name="analytics.reports.exchange" amqp-template="amqptemplate" />

responding side:

<int:channel id="analytics.reports.requests.channel" />  <int:channel id="analytics.reports.responses.channel" />     <int-amqp:inbound-gateway request-channel="analytics.reports.requests.channel" reply-channel="analytics.reports.responses.channel"     queue-names="analytics.reports.queue" connection-factory="rabbitconnectionfactory" message-converter="jsonmessageconverter"/>  <int:service-activator input-channel="analytics.reports.requests.channel" output-channel="analytics.reports.responses.channel"      ref="analyticsreporter" method="getanalytics"/> <bean class="com.project.analytics.reporters.simpleanalyticsreporter" id="analyticsreporter"/>   public class simpleanalyticsreporter {  @sneakythrows public analyticsreponse getanalytics(entitymessage message) {     return new analyticsreponse("hello");  }

as far aren't interested in org.springframework.integration.mapping.support.jsonheaders, because use jsonmessageconverter, should filter them (<header-filter>) or ignore amqp headers (mapped-request-headers="-" or mapped-reply-headers="-").

however see wasn't right yesterday (https://jira.springsource.org/browse/int-3285) , reopen issue revise how can deal standard headers default allow work similar scenarios. thank you!
