59.3. 以编程方式添加拦截器

拦截器供应商接口

package org.apache.cxf.interceptor;

import java.util.List;

public interface InterceptorProvider
{
    List<Interceptor<? extends Message>> getInInterceptors();

    List<Interceptor<? extends Message>> getOutInterceptors();

    List<Interceptor<? extends Message>> getInFaultInterceptors();

    List<Interceptor<? extends Message>> getOutFaultInterceptors();
}

以编程方式将拦截器附加到消费者

package com.fusesource.demo;

import java.io.File;
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;

import org.apache.cxf.endpoint.Client;

public class Client
{
  public static void main(String args[])
  {
    QName serviceName = new QName("http://demo.eric.org", "stockQuoteReporter");
    Service s = Service.create(serviceName);

    QName portName = new QName("http://demo.eric.org", "stockQuoteReporterPort");
    s.addPort(portName, "http://schemas.xmlsoap.org/soap/", "http://localhost:9000/EricStockQuote");

    quoteReporter proxy = s.getPort(portName, quoteReporter.class);

    Client cxfClient = (Client) proxy;

    ValidateInterceptor validInterceptor = new ValidateInterceptor();
    cxfClient.getInInterceptor().add(validInterceptor);

    ...
  }
}

以编程方式将拦截器附加到服务提供商

package com.fusesource.demo;
import java.util.*;

import org.apache.cxf.endpoint.Server;
import org.apache.cxf.frontend.ServerFactoryBean;
import org.apache.cxf.frontend.EndpointImpl;

public class stockQuoteReporter implements quoteReporter
{
  ...
  public stockQuoteReporter()
  {
    ServerFactoryBean sfb = new ServerFactoryBean();
    Server server = sfb.create();
    EndpointImpl endpt = server.getEndpoint();

    AuthTokenInterceptor authInterceptor = new AuthTokenInterceptor();

    endpt.getOutInterceptor().add(authInterceptor);
  }
}

将拦截器附加到总线

import org.apache.cxf.BusFactory;
org.apache.cxf.Bus;

...

Bus bus = BusFactory.getDefaultBus();

WatchInterceptor watchInterceptor = new WatchInterceptor();

bus..getInInterceptor().add(watchInterceptor);

...

在链注解中列出拦截器的语法

interceptors={"interceptor1", "interceptor2", ..., "interceptorN"}

将拦截器附加到服务实现中

import org.apache.cxf.interceptor.InInterceptors;

@InInterceptors(interceptors={"com.sayhi.interceptors.FirstLast", "com.sayhi.interceptors.LogName"})
public class SayHiImpl implements SayHi
{
  ...
}
