XFire发送和接收复杂类型、对象
这两天在学习WebService，首先选择的是XFire。服务端返回对象和集合，在客户端处理的时候我使用了两种方式。一种是自己手动创建客户端的代理接口和实体类。类所在的包同服务端一致；还有一种是我使用了Ant生成的客户端代码。第一种手动创建的测试返回值都没有问题，但是第二种方式我使用了xmlBeans工具所以生成的方法返回值类型是XmlObject，这里要怎么处理呢，要自己解析这个xml文件吗？XFire有没有自己的方式，可以直接把返回的XmlObject转换成实体对象呢？还有，我服务端一个方法接收一个实体类型的对象，在客户端调用这个方法的时候要如何传入对象呢？百度了一天也没有一个能很好的说明解决方法的，入门的helloword倒是不少。希望高手能帮忙看看，提点一小，或给点解决的意见。
下面是代码：
服务端代码结构：
实体类User.java
Java代码 
public class User implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private String name;
private Date birthday;
//set,get..............服务端服务类IHelloServiceImpl(接口IHelloService的代码就不贴了)
Java代码
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import com.study.bo.User;
import com.study.service.IHelloService;
public class IHelloServiceImpl implements IHelloService {
public String copyMessage(String msg) {
return msg;
}
public List getList(List t) {
for(int i = 0 ; i < t.size() ; i++){
System.out.println(t.get(i));
}
List al = new ArrayList();
User user = new User();
user.setName("路人甲");
user.setBirthday(new Date());
al.add(user);
return al;
}
public void sayHello() {
System.out.println("hello world");
}
public User getUserByName(String name){
User user = new User();
user.setName(name);
return user;
}
}因为使用了List类型，所以要做一个映射IHelloService.aegis.xml
Java代码
<?xml version="1.0" encoding="UTF-8"?> <mappings> <mapping> <method name="getList"> <parameter index="0" componentType="java.lang.String" /> <return-type componentType="com.study.bo.User" /> </method> </mapping> </mappings>
services.xml和web.xml的代码就不贴了，相信大家都知道
下面是客户端的：
代码结构：
客户端创建方式一：手动ClientFromInterface.java
Java代码
package com.study.client;
import java.net.MalformedURLException;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;
import com.study.bo.User;
import com.study.service.IHelloService;
/**
* 使用WEB服务端提供的接口来创建客户端
* @author sysuser
*
*/
public class ClientFromInterface {
/**
* 1.使用XFire的ObjectServiceFactory从IHelloService接口创建一个服务模型Service<br/>
* 2.创建一个服务端代理<br/>
* 3.使用代理访问服务端方法
* @param args
* @throws MalformedURLException
*/
public static void main(String[] args) throws MalformedURLException {
//使用XFire的ObjectServiceFactory从IHelloService接口创建一个服务模型Service
Service serviceModel = new ObjectServiceFactory().create(IHelloService.class);
//访问地址
String url = "http://127.0.0.1:8181/StudyXFireService/services/HelloService";
//创建代理工厂
XFireProxyFactory proxyFactory = new XFireProxyFactory();
//通过proxyFactory，使用服务模型serviceModel和服务端点URL(用来获得WSDL)
//得到一个服务的本地代理，这个代理就是实际的客户端
IHelloService client = (IHelloService)proxyFactory.create(serviceModel, url);
client.sayHello();
String msg = client.copyMessage("路人小子 ");
System.out.println(msg);
User user = client.getUserByName("gaojun");
System.out.println(user.getName());
List<User> userList = new ArrayList<User>();
User user1 = new User();
user1.setAge(10);
user1.setName("name_1");
user1.setBirthday(new Date());
User user2 = new User();
user2.setAge(20);
user2.setName("name_2");
user2.setBirthday(new Date());
userList.add(user1);
userList.add(user2);
List<User> list1 = client.getList(userList);
for(int i = 0 ; i < list1.size() ; i++){
System.out.println(list1.get(i).getName());
System.out.println(list1.get(i).getBirthday());
}
}
}
这种方式下，传入和接收User,List都没有问题。
客户端创建方式二：ant生成方式
HelloServicePortType.java
Java代码
package com.study.antService;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import org.apache.xmlbeans.XmlObject;
@WebService(name = "HelloServicePortType", targetNamespace = "http://www.study.xfire/HelloService")
@SOAPBinding(use = SOAPBinding.Use.LITERAL, parameterStyle = SOAPBinding.ParameterStyle.WRAPPED)
public interface HelloServicePortType {
@WebMethod(operationName = "getUserByName", action = "")
@WebResult(name = "out", targetNamespace = "http://www.study.xfire/HelloService")
public XmlObject getUserByName(
@WebParam(name = "in0", targetNamespace = "http://www.study.xfire/HelloService")
String in0);
@WebMethod(operationName = "getList", action = "")
@WebResult(name = "out", targetNamespace = "http://www.study.xfire/HelloService")
public XmlObject getList(
@WebParam(name = "in0", targetNamespace = "http://www.study.xfire/HelloService")
XmlObject in0);
@WebMethod(operationName = "copyMessage", action = "")
@WebResult(name = "out", targetNamespace = "http://www.study.xfire/HelloService")
public String copyMessage(
@WebParam(name = "in0", targetNamespace = "http://www.study.xfire/HelloService")
String in0);
@WebMethod(operationName = "sayHello", action = "")
public void sayHello();
}HelloServiceClient.java
Java代码

endpoints.put(new QName("http://www.study.xfire/HelloService", "HelloServicePortTypeLocalEndpoint"), HelloServicePortTypeLocalEndpointEP);
Endpoint HelloServiceHttpPortEP = service0 .addEndpoint(new QName("http://www.study.xfire/HelloService", "HelloServiceHttpPort"), new QName("http://www.study.xfire/HelloService", "HelloServiceHttpBinding"), "http://127.0.0.1:8181/StudyXFireService/services/HelloService");
endpoints.put(new QName("http://www.study.xfire/HelloService", "HelloServiceHttpPort"), HelloServiceHttpPortEP);
}
public Object getEndpoint(Endpoint endpoint) {
try {
return proxyFactory.create((endpoint).getBinding(), (endpoint).getUrl());
} catch (MalformedURLException e) {
throw new XFireRuntimeException("Invalid URL", e);
}
}
public Object getEndpoint(QName name) {
Endpoint endpoint = ((Endpoint) endpoints.get((name)));
if ((endpoint) == null) {
throw new IllegalStateException("No such endpoint!");
}
return getEndpoint((endpoint));
}
public Collection getEndpoints() {
return endpoints.values();
}
private void create0() {
TransportManager tm = (org.codehaus.xfire.XFireFactory.newInstance().getXFire().getTransportManager());
HashMap props = new HashMap();
props.put("annotations.allow.interface", true);
AnnotationServiceFactory asf = new AnnotationServiceFactory(new Jsr181WebAnnotations(), tm,
new AegisBindingProvider(new XmlBeansTypeRegistry()));
asf.setBindingCreationEnabled(false);
service0 = asf.create((com.study.antService.HelloServicePortType.class), props);

}
}
public HelloServicePortType getHelloServicePortTypeLocalEndpoint() {
return ((HelloServicePortType)(this).getEndpoint(new QName("http://www.study.xfire/HelloService", "HelloServicePortTypeLocalEndpoint")));
}
public HelloServicePortType getHelloServicePortTypeLocalEndpoint(String url) {
HelloServicePortType var = getHelloServicePortTypeLocalEndpoint();
org.codehaus.xfire.client.Client.getInstance(var).setUrl(url);
return var;
}
public HelloServicePortType getHelloServiceHttpPort() {
return ((HelloServicePortType)(this).getEndpoint(new QName("http://www.study.xfire/HelloService", "HelloServiceHttpPort")));
}
public HelloServicePortType getHelloServiceHttpPort(String url) {
HelloServicePortType var = getHelloServiceHttpPort();
org.codehaus.xfire.client.Client.getInstance(var).setUrl(url);
return var;
}
}HelloServiceImpl.java
Java代码
package com.study.antService;
import javax.jws.WebService;
import org.apache.xmlbeans.XmlObject;
@WebService(serviceName = "HelloService", targetNamespace = "http://www.study.xfire/HelloService",
endpointInterface = "com.study.client.HelloServicePortType")
public class HelloServiceImpl
implements HelloServicePortType
{
public XmlObject getUserByName(String in0) {
throw new UnsupportedOperationException();
}
public XmlObject getList(XmlObject in0) {
throw new UnsupportedOperationException();
}
public String copyMessage(String in0) {
throw new UnsupportedOperationException();
}
public void sayHello() {
throw new UnsupportedOperationException();
}
}测试类如下：
Java代码
package com.study.client;
import org.apache.xmlbeans.XmlObject;
import com.study.antService.HelloServiceClient;
import com.study.antService.HelloServicePortType;
import com.study.bo.User;
public class HelloWordTest {
public static void main(String[] args) {
HelloServiceClient client = new HelloServiceClient();
HelloServicePortType service = client.getHelloServiceHttpPort();
service.sayHello();
String msg = "信息";
String ms = service.copyMessage(msg);
System.out.println(ms);
XmlObject xmlObject = service.getUserByName("snm");
System.out.println(xmlObject.toString());
}
}可以看到，测试类返回的并不是User对象而是XmlObject，到这一步要如何处理呢？只能自己使用Dom或是其它工具解析xml了吗？XFire自己不提供转换成对象的功能吗？另xml打印结果如下：
Java代码
<ns1:out xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns1="http://www.study.xfire/HelloService"> <age xmlns="http://bo.study.com">0</age> <name xmlns="http://bo.study.com">snm</name> </ns1:out>
代码有点多，主要是希望大家能看清楚。提点一下到这一步应该如果进行下去。
在实际的应用开发过程中，为了实现多平台的适用性，服务端和客户端一般都接收或返回xml文件的字符串，而尽量不使用复杂对象的吗？如果那样，对xml文件又是如何处理的呢，也是自己解析吗？
在解决问题的过程中看到SOAP，不知道是干什么用的，找时候学习一下。
