如何在自定義cxf攔截器中使用Spring Autowired？

Question

當@Autowired用於自定義cxf攔截器時，我似乎遇到了一個小問題。 我的用例是我想記錄肥皂消息並使用AMQP將這些消息發送到另一個系統。這個過程適用於正常的服務等。 但無論我做什麼，所需的屬性都不會自動裝配並保持爲空。

我檢查了春季DI日誌和上下文被掃描和拾取，所以我錯過了什麼？

這在CXF攔截器中甚至可能嗎？

@Component 
public class LogInInterceptor extends AbstractSoapInterceptor { 

    private @Value("#{rabbitMQProperties['rabbitmq.binding.log.soap']}") 
    String binding; 

    @Autowired 
    AmqpTemplate amqpTemplate; 

    public LogInInterceptor() { 
     super(Phase.RECEIVE); 
    } 

    @Override 
    public void handleMessage(SoapMessage soapMessage) throws Fault { 
     logIt(soapMessage); 
    } 

    private void logIt(SoapMessage message) throws Fault { 
     // rest of the code omitted...!!!  
     amqpTemplate.convertAndSend(binding, buffer.toString()); 
    } 

} 

Answer 1

不能混合@InInterceptors（一CXF註釋）和@Component（Spring的註解）。這將創建兩個獨立的攔截器實例：Spring的依賴關係被注入的實例，以及由CXF創建的實例。 （您提供一流的名字在@InInterceptors註釋，而不是一個bean ID，所以CXF沒有辦法知道你已經創造了Spring上下文實例的方式。）

取出@InInterceptors註釋和，除了component scan ：

<context:component-scan base-package="org.example.config"/> 

您還需要像這樣在你的應用環境：

<jaxws:endpoint id="myWebService" address="/MyWebService"> 
    <jaxws:inInterceptors> 
     <ref bean="myInInterceptor" /> 
    </jaxws:inInterceptors> 
</jaxws:endpoint>

我知道這是一個老問題，但喬納森·W公司的回答幫我，我想補充到它。

我這是怎麼了自定義的攔截和@Autowired與Spring 1.3.1引導工作：

http://cxf.apache.org/docs/jax-ws-configuration.html

import java.util.Arrays; 

import javax.jws.WebService; 

import org.apache.cxf.Bus; 
import org.apache.cxf.interceptor.LoggingInInterceptor; 
import org.apache.cxf.jaxws.EndpointImpl; 
import org.apache.cxf.transport.servlet.CXFServlet; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.EnableAutoConfiguration; 
import org.springframework.boot.builder.SpringApplicationBuilder; 
import org.springframework.boot.context.embedded.ServletRegistrationBean; 
import org.springframework.boot.context.web.SpringBootServletInitializer; 
import org.springframework.context.ApplicationContext; 
import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.context.annotation.ImportResource; 

@Configuration 
@EnableAutoConfiguration 
@ImportResource({ "classpath:META-INF/cxf/cxf.xml" }) 
public class Application extends SpringBootServletInitializer { 

    @Autowired 
    private ApplicationContext applicationContext; 

    @Autowired 
    private MyInterceptor myInterceptor; 

    @Autowired 
    private HelloWorldImpl helloWorldImpl; 

    public static void main(String[] args) { 
     SpringApplication.run(Application.class, args); 
    } 

    // Replaces the need for web.xml 
    @Bean 
    public ServletRegistrationBean servletRegistrationBean(ApplicationContext context) { 
     return new ServletRegistrationBean(new CXFServlet(), "/api/*"); 
    } 

    // Replaces cxf-servlet.xml 
    @Bean 
    // <jaxws:endpoint id="helloWorld" implementor="demo.spring.service.HelloWorldImpl" address="/HelloWorld"/> 
    public EndpointImpl helloService() { 
     Bus bus = (Bus) applicationContext.getBean(Bus.DEFAULT_BUS_ID); 
     EndpointImpl endpoint = new EndpointImpl(bus, helloWorldImpl); 

     // Set interceptors here 
     endpoint.setInInterceptors(Arrays.asList(myInterceptor)); 

     endpoint.publish("/hello"); 
     return endpoint; 
    } 


    // Used when deploying to a standalone servlet container, i.e. tomcat 
    @Override 
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { 
     return application.sources(Application.class); 
    } 

    // Web service endpoint 
    @WebService(endpointInterface = "demo.spring.service.HelloWorld") 
    //@InInterceptors not defined here 
    public static class HelloWorldImpl { 

    } 

    public static class MyInterceptor extends LoggingInInterceptor { 
     // @Autowired works here 
    } 

}
