java - Spring 集成:@ServiceActivator无法正常工作

我有以下课程：

@Configuration
public class SpringIntegrationTest {

    @Bean
    public SimpleWebServiceInboundGateway testInboundGateWay (){
        SimpleWebServiceInboundGateway simpleWebServiceInboundGateway = new SimpleWebServiceInboundGateway();
        simpleWebServiceInboundGateway.setRequestChannelName("testChannel");
        simpleWebServiceInboundGateway.setReplyChannelName("testChannel2");
        return simpleWebServiceInboundGateway;
    }

    @Bean
    public MessageChannel testChannel() {
        return new DirectChannel();
    }

    @Bean
    public MessageChannel testChannel2() {
        return new DirectChannel();
    }

    @ServiceActivator(inputChannel = "testChannel", outputChannel = "testChannel2")
    public DOMSource foo(DOMSource request) {
        System.out.println("asd");
        return request;
    }

    @Bean
    public EndpointMapping soapActionEndpointMapping(SimpleWebServiceInboundGateway testInboundGateWay ) {
        UriEndpointMapping uriEndpointMapping = new UriEndpointMapping();
        uriEndpointMapping.setUsePath(true);
        uriEndpointMapping.setEndpointMap(createEndpointMapping(testInboundGateWay ));
        return uriEndpointMapping;
    }

    private Map<String, Object> createEndpointMapping(SimpleWebServiceInboundGateway testInboundGateWay ) {
        Map<String, Object> endpointMap = new HashMap<>();
        endpointMap.put("/ws/test", testInboundGateWay );
        return endpointMap;
    }

}

即使服务激活器订阅了“ testChannel”，我仍然收到以下消息：


  o.s.i.w.SimpleWebServiceInboundGateway-网关sendAndReceive中发生故障：分派器没有频道“ org.springframework.web.context.WebApplicationContext：/ MyProject restful API.testChannel”的订阅者。嵌套的异常是org.springframework.integration.MessageDispatchingException：调度程序没有订阅者


我究竟做错了什么？

最佳答案

您需要将@EnableIntegration添加到配置类之一。
