I am trying to make gwt-2.7 work with spring-4.2.3.Configurations are:

web.xml

<!-- spring config -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- Spring GWT integration -->
<servlet>
    <servlet-name>springGwtRemoteServiceServlet</servlet-name>
    <servlet-class>org.spring4gwt.server.SpringGwtRemoteServiceServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>springGwtRemoteServiceServlet</servlet-name>
    <url-pattern>/idp_web/service/*</url-pattern>
</servlet-mapping>

applicationContext.xml

<beans 
...
http://www.springframework.org/schema/beans/spring-beans-4.2.xsd 
....
default-lazy-init="true">

<!-- auto-inject bean by annotation mechanism -->
<context:component-scan
    base-package="com.vsi.idp.analysis.server,
                    com.vsi.idp.base.server,
                    com.vsi.idp.kpi.server,
                    com.vsi.idp.map.server,
                    com.vsi.idp.statistics.server" />

     //other configurations
</beans>

GWT services

@RemoteServiceRelativePath("service/querySenior")
public interface SeniorQueryService extends RemoteService{...}

service impl

@Service("querySenior")
public class SeniorQueryServiceImpl extends RemoteServiceServlet implements SeniorQueryService{...}

Spock unit test works fine

@ContextConfiguration(locations = "file:war/WEB-INF/applicationContext.xml")
public class SeniorQueryServiceImplTest extends Specification{

  @Autowired
  SeniorQueryServiceImpl service

  def "query by full address"(){
      //blabla
  }
}

Running gwt project tells:

Failed to load resource: the server responded with a status of 500 (Server Error)

Error stack looks like:

[WARN] Exception while dispatching incoming RPC call
java.lang.IllegalArgumentException: Spring bean not found: querySenior
at org.spring4gwt.server.SpringGwtRemoteServiceServlet.getBean(SpringGwtRemoteServiceServlet.java:96)
at org.spring4gwt.server.SpringGwtRemoteServiceServlet.getBean(SpringGwtRemoteServiceServlet.java:55)
at org.spring4gwt.server.SpringGwtRemoteServiceServlet.processCall(SpringGwtRemoteServiceServlet.java:31)
at com.google.gwt.user.server.rpc.RemoteServiceServlet.processPost(RemoteServiceServlet.java:373)

I think:

1,"500(server error)" tells that gwt has recognized spring service
2,spring service unit test works fine,so spring configuration is right
