java - Spring Integration: gateway bean not found -

i try using spring integration in different jars. in a.jar si-context.xml:

    <context:annotation-config />     <int:annotation-config />      <int:channel id="upperservicechannel">         <int:priority-queue />     </int:channel>      <int:gateway id="uppergateway" default-request-timeout="5000"         default-reply-timeout="5000" default-request-channel="upperservicechannel"         service-interface="com.company.proj.gw.iupperstringconversation">         <int:method name="touppercase" />     </int:gateway>       <bean id="touppercaseservice" class="com.company.proj.service.touppercaseservice" />     <int:service-activator id="serviceactivatortouppercase"         input-channel="upperservicechannel" method="touppercase" ref="touppercaseservice" />      <int:poller id="poller" default="true" fixed-delay="1000" />     <context:component-scan base-package="com.company"/> 

in bean i'm using gateway:

 @component(value = "upper")     public class upperadapter extends aadapter<message<string>> {      @autowired     iupperstringconversation gw; 

it's working. problem is, if try using upperadapter other project (b.jar). b-context.xml:

<import resource="classpath*:/*si-context.xml" /> <context:annotation-config /> <int:annotation-config />       @component(value="router") public class router {      @autowired     private map<string, aadapter<?>> adapters; 

and here get:

caused by: org.springframework.beans.factory.beancreationexception: error creating bean name 'upper': injection of autowired dependencies failed; nested exception org.springframework.beans.factory.beancreationexception: not autowire field: com.company.proj.gw.iupperstringconversation com.company.proj.adapter.upperadapter.gw; nested exception org.springframework.beans.factory.nosuchbeandefinitionexception: no matching bean of type [com.company.proj.gw.iupperstringconversation] found dependency: expected @ least 1 bean qualifies autowire candidate dependency. dependency annotations: {@org.springframework.beans.factory.annotation.autowired(required=true)} 

after set spring log level debug, information:

debug o.s.c.a.classpathbeandefinitionscanner - ignored because not concrete top-level class: url [jar:file:/home/tomto/documents/workspace-sts/integration-fw/src/main/resources/meta-inf/lib/integration-fw-module-string-0.0.1-snapshot.jar!/com/company/proj/gw/iupperstringconversation.class] 

of course, it's true, becouse (maybe i'm wrong ;)) @ runtime generated gateway spring.

the iupperstringconversation:

public interface iupperstringconversation {     public string touppercase(string text); } 

what missed?

thx!

we had similar issue, our gateways not getting injected our service object:

project structure: ---------------- -parent/ -common/    --gateways defined here -module-a/ -module-b/ 

the exception message received in module-b was:

org.springframework.beans.factory.beancreationexception: ... injection of autowired dependencies failed ... illegalargumentexception: class must not null 

apparently issue being caused conflicting dependencies had on module-b classpath. after cleaned spring dependencies in pom.xml worked!
