在自定义 cxf 拦截器中使用 @Autowired 时，我似乎遇到了一个小问题。我的用例是我想记录肥皂消息并使用 AMQP 将这些消息发送到另一个系统。此过程适用于普通服务等。但无论我做什么，所需的属性都不会自动装配并保持为空。

我检查了 Spring DI 日志并扫描并提取了上下文，那么我错过了什么？

这在 CXF 拦截器中是否可行？

@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());
    }

}

您不能混合@InInterceptors使用（CXF 注释）和 @Component（Spring 注释）。这将创建您的拦截器的两个独立实例：一个其依赖项由 Spring 注入，另一个由 CXF 创建。（您在@InInterceptors注解中提供类名，而不是 bean ID，因此 CXF 无法知道您已经在 Spring 上下文中创建了一个实例。）

删除@InInterceptors注释，除了组件 scan：

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

您还需要在应用程序上下文中使用类似的内容：

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

我知道这是一个老问题，但乔纳森 W 的回答对我有帮助，我想补充一下。

这就是我获得自定义拦截器并@Autowired使用 Spring Boot 1.3.1 的方式：

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
    }

}
