'没有端点适配器'例外 - 带有spring-boot和spring-ws的apache-camel

Mat*_*lls 3 spring web-services spring-ws apache-camel spring-boot

我试图在spring-boot应用程序中使用apache-camel(2.15.2)来处理传入的Web服务调用.

我根据这里的指南创建了一个初始工作的春季启动项目(没有骆驼)http://spring.io/guides/gs/producing-web-service/

然后我尝试将Camel:Spring Web Services组件集成为Consumer来处理传入的Web服务请求,遵循"公开Web服务"部分中的指导原则http://camel.apache.org/spring-web-services.html

WebServiceConfig.java

import org.apache.camel.component.spring.ws.bean.CamelEndpointMapping;

@EnableWs
@Configuration
public class WebServiceConfig extends WsConfigurerAdapter {

    @Bean
    public ServletRegistrationBean messageDispatcherServlet(ApplicationContext applicationContext) {
        MessageDispatcherServlet servlet = new MessageDispatcherServlet();
        servlet.setApplicationContext(applicationContext);
        servlet.setTransformWsdlLocations(true);
        return new ServletRegistrationBean(servlet, "/ws/*");
    }

    // default wsdl stuff here...

    // exposing the endpoint mapping bean here rather than in spring-ws-servlet.xml (seems to work)
    @Bean  public CamelEndpointMapping  endpointMapping() {
        return new CamelEndpointMapping();
    }

根据日志(如下),传入的请求已成功映射到我的Camel Consumer,但随后失败并显示"No adapter for endpoint"

我研究了很多针对端点问题的无适配器,其中大多数似乎都是由端点的返回类型引起的.但是,我只是创建了一个camel路由,所以假设camel-spring-ws集成应该提供实际的端点.

我是否错过了一个关键的配置/注释或者是否存在更基本的问题(可能是某些版本不兼容)？任何帮助或见解非常感谢.

当使用spring引导时,它只注册DefaultMethodEndpointAdapter配置注释驱动的Spring WS编程模型.这使得可以使用各种注释一样@Endpoint,@Payload自动侦测.

在我们的例子中,spring-ws端点必须将ws请求移交给camel端点,DefaultMethodEndpointAdapter不会为我们做那个工作.

下面是spring框架中执行端点适配器注册的代码部分,

private void initEndpointAdapters(ApplicationContext applicationContext)抛出BeansException {

    if (endpointAdapters == null) {
        Map<String, EndpointAdapter> matchingBeans = BeanFactoryUtils
                .beansOfTypeIncludingAncestors(applicationContext, EndpointAdapter.class, true, false);

if(!matchingBeans.isEmpty()){endpointAdapters = new ArrayList(matchingBeans.values()); Collections.sort(endpointAdapters,new OrderComparator()); }

        else {
            endpointAdapters =
                    defaultStrategiesHelper.getDefaultStrategies(EndpointAdapter.class, applicationContext);
            if (logger.isDebugEnabled()) {
                logger.debug("No EndpointAdapters found, using defaults");
            }
        }
    }
}

当我们用弹簧启动,DefaultMethodEndpointAdapter被注册,因此第一"如果块"运行,因此它没有注册其他适配器一样MessageEndpointAdapter,PayloadEndpointAdapter等等.

在这种情况下我们需要的是,除了DefaultMethodEndpointAdapter必须注册MessageEndpointAdapter以将spring-ws卸载到camel端点之外.

所以在WebServiceConfig课堂上,添加以下代码,

@Bean
    public EndpointAdapter messageEndpointAdapter() {
        return new MessageEndpointAdapter();
    }

然后交接魔法发生了.

Spring-ws和camel切换需要MessageEndpointAdapter.
