CXF之動態(tài)客戶端實例

 江江385 2013-01-30

通常創(chuàng)建一個web服務的客戶端包括SEI的java接口和客戶端輸入輸出應用的一些java類，這不總是可取的或實用的。

CXF支持不同的選擇，允許一個應用連接到服務而不使用SEI和一些數(shù)據類。本頁面介紹CXF的動態(tài)客戶端工具，有了動態(tài)客戶端，CXF就可以在運行時生成SEI和一些Bean類，也允許你通過API調用操作,即采取對象或使用反射來應用代理。

服務接口：

[java:firstline[1]] view plaincopyprint?
  1. package test.cxf;
  2. import javax.jws.WebParam;
  3. import javax.jws.WebService;
  4. @WebService
  5. public interface HelloWorld {
  6. public Person sayPerson(
  7. @WebParam(name="personName")String personName,
  8. @WebParam(name="address")Address address);
  9. }

服務實現(xiàn)類:

[java:firstline[1]] view plaincopyprint?
  1. package test.cxf;
  2. import javax.jws.WebService;
  3. @WebService(endpointInterface="test.cxf.HelloWorld")
  4. public class HelloWorldImpl implements HelloWorld {
  5. public Person sayPerson(String personName, Address address) {
  7. Person p = new Person();
  8. p.setPersonName(personName);
  9. p.setAddress(address);
  10. p.setAge(30);
  12. System.out.println("server--" + p.getPersonName());
  13. System.out.println("server--" + p.getAge());
  14. System.out.println("server--" + p.getAddress().getAddress1()+":" + p.getAddress().getAddress2());
  15. return p;
  16. }
  17. }

對象 Person：

[java:firstline[1]] view plaincopyprint?
  1. package test.cxf;
  2. import java.io.Serializable;
  3. import javax.xml.bind.annotation.XmlAccessType;
  4. import javax.xml.bind.annotation.XmlAccessorType;
  5. @XmlAccessorType(XmlAccessType.FIELD)
  6. public class Person implements Serializable{
  7. private String personName;
  8. private Integer age;
  9. private Address address;
  10. public String getPersonName() {
  11. return personName;
  12. }
  13. public void setPersonName(String personName) {
  14. this.personName = personName;
  15. }
  16. public Integer getAge() {
  17. return age;
  18. }
  19. public void setAge(Integer age) {
  20. this.age = age;
  21. }
  22. public Address getAddress() {
  23. return address;
  24. }
  25. public void setAddress(Address address) {
  26. this.address = address;
  27. }
  28. }

對象Address:

[java:firstline[1]] view plaincopyprint?
  1. package test.cxf;
  2. import java.io.Serializable;
  3. import javax.xml.bind.annotation.XmlAccessType;
  4. import javax.xml.bind.annotation.XmlAccessorType;
  5. @XmlAccessorType(XmlAccessType.FIELD)
  6. public class Address implements Serializable{
  7. private String address1;
  8. private String address2;
  9. public String getAddress1() {
  10. return address1;
  11. }
  12. public void setAddress1(String address1) {
  13. this.address1 = address1;
  14. }
  15. public String getAddress2() {
  16. return address2;
  17. }
  18. public void setAddress2(String address2) {
  19. this.address2 = address2;
  20. }
  21. }

異常定義：

[java:firstline[1]] view plaincopyprint?
  1. package test.cxf;
  2. import javax.xml.bind.annotation.XmlAccessType;
  3. import javax.xml.bind.annotation.XmlAccessorType;
  4. import javax.xml.ws.WebFault;
  5. @XmlAccessorType(XmlAccessType.FIELD)
  6. @WebFault(name="DynamicClientException")
  7. public class DynamicClientException extends Exception {
  8. public DynamicClientException(){
  9. super();
  10. System.out.println("DynamicClientException!!!");
  11. }
  12. }

服務端配置：

[java:firstline[1]] view plaincopyprint?
  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www./schema/beans"
  3. xmlns:xsi="http://www./2001/XMLSchema-instance"
  4. xmlns:jaxws="http://cxf./jaxws"
  5. xsi:schemaLocation="
  6. http://www./schema/beans http://www./schema/beans/spring-beans.xsd
  7. http://cxf./jaxws http://cxf./schemas/jaxws.xsd">
  8. <import resource="classpath:META-INF/cxf/cxf.xml" />
  9. <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
  10. <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
  12. <bean id="helloworldImpl" class="test.cxf.HelloWorldImpl"/>
  13. <jaxws:endpoint id="helloworldService" implementor="#helloworldImpl" address="/helloworld"/>
  14. </beans>

客戶端調用-----關鍵就在這里：

[java:firstline[1]] view plaincopyprint?
  1. package test.cxf;
  2. import java.lang.reflect.Method;
  3. import org.apache.cxf.endpoint.Client;
  4. import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
  5. public class ClientObj {
  6. public static void main(String[] args){
  7. JaxWsDynamicClientFactory dynamicClient = JaxWsDynamicClientFactory.newInstance();
  8. Client client = dynamicClient.createClient("http://localhost:8085/cxf-dynamicClientFactory/service/helloworld?wsdl");
  9. Object address = null;
  10. try {
  11. address = Thread.currentThread().getContextClassLoader().loadClass("test.cxf.Address").newInstance();
  12. Method m2 = address.getClass().getMethod("setAddress1",String.class);
  13. Method m3 = address.getClass().getMethod("setAddress2",String.class);
  14. m2.invoke(address, "qqqqqqq");
  15. m3.invoke(address, "ttttttt");
  16. Object[] rspArr = client.invoke("sayPerson", "fhd", address);
  17. if (null != rspArr && rspArr.length > 0) {
  19. Method m4 = rspArr[0].getClass().getMethod("getAge");
  20. Object obj1 = m4.invoke(rspArr[0]);
  21. System.out.println("ggggg:" + (Integer)obj1);
  23. Method m5 = rspArr[0].getClass().getMethod("getPersonName");
  24. Object obj2 = m5.invoke(rspArr[0]);
  25. System.out.println("vvvvv" + (String)obj2);
  27. Method m6 = rspArr[0].getClass().getMethod("getAddress");
  28. Object obj3 = m6.invoke(rspArr[0]);
  29. Method m7 = obj3.getClass().getMethod("getAddress1");
  30. Method m8 = obj3.getClass().getMethod("getAddress2");
  31. Object o1 = m7.invoke(obj3);
  32. Object o2 = m8.invoke(obj3);
  33. System.out.println("ssssss" + (String)o1 + "<<>>" + (String)o2);
  34. }
  36. } catch (Exception e) {
  37. e.printStackTrace();
  38. }
  39. }
  40. }

你可能會問自己下面這個問題：“類名'com.acme.Person'從哪里來”？是通過運行"wsdl2java'并審查結果來得到類名。
