CXF的拦截器

理解

为什么设计拦截器？

为了在webservice请求过程中,能动态操作请求和响应数据, CXF设计了拦截器.

拦截器分类：

按所处的位置分：服务器端拦截器，客户端拦截器
按消息的方向分：入拦截器，出拦截器
按定义者分：系统拦截器，自定义拦截器

基于jdk的webservice没有拦截器的功能实现。

接口方法:

import javax.jws.WebMethod;
import javax.jws.WebService;


@WebService
public interface HelloInt {
    
    @WebMethod
    public String sayHello(String name );

}

实现：

import javax.jws.WebService;

@WebService
public class HelloImpl implements HelloInt {

    @Override
    public String sayHello(String name) {
        return "hello,"+name;
    }

}

测试方法:

import javax.xml.ws.Endpoint;

import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.EndpointImpl;


public class ServerTest {
    
    public static void main(String[] args) {
        String address = "http://192.168.1.64:8989/d01ws/hello";
        Endpoint point=Endpoint.publish(address,new HelloImpl());
        EndpointImpl impl = (EndpointImpl) point;
        //添加系统日志拦截器
        impl.getInInterceptors().add(new LoggingInInterceptor());
        impl.getInInterceptors().add(new LoggingOutInterceptor());
        System.out.println("webservice发布成功");
    }

}

利用eclipse 自带的webservice 浏览器添加请求参数 kity,

另外附上wsdl的文档结构图:

<?xml version=‘1.0‘ encoding=‘UTF-8‘?><wsdl:definitions xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://wa.com/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:ns1="http://schemas.xmlsoap.org/soap/http" name="HelloImplService" targetNamespace="http://wa.com/">

<xs:element name="sayHelloResponse" type="tns:sayHelloResponse"/>
<xs:complexType name="sayHello">
<xs:sequence>
<xs:element minOccurs="0" name="arg0" type="xs:string"/>
</xs:sequence>
</xs:complexType>

  </wsdl:portType>

    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
    <wsdl:operation name="sayHello">
      <soap:operation soapAction="" style="document"/>
      <wsdl:input name="sayHello">
        <soap:body use="literal"/>
      </wsdl:input>
      <wsdl:output name="sayHelloResponse">
        <soap:body use="literal"/>
      </wsdl:output>
    </wsdl:operation>
  </wsdl:binding>
  <wsdl:service name="HelloImplService">
    <wsdl:port binding="tns:HelloImplServiceSoapBinding" name="HelloImplPort">
      <soap:address location="http://192.168.1.64:8989/d01ws/hello"/>
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

二、客户端调用webservice:

先用wsdl2java 生成客户端代码:

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.frontend.ClientProxy;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;

import com.wa.HelloImplService;
import com.wa.HelloInt;

/**
 * 客户端进行测试
 *
 */
public class ClientTest {
    
    public static void main(String[] args) {
        
        HelloImplService service = new HelloImplService();
        HelloInt hello = service.getHelloImplPort();
        //客户端拦截器
        Client client =ClientProxy.getClient(hello);
        client.getInInterceptors().add(new LoggingInInterceptor());
        client.getInInterceptors().add(new LoggingOutInterceptor());
        System.out.println(hello.sayHello("what do you say?please say agin."));
    }

}

可以看到:

服务端的日志信息为：
