webservice简单例子

时间：2020-10-10分类：WebService作者：编程之家

最近重新熟悉下webservice知识，以前用的是axis2，现在用另一种方式spring xfire来实现简单的webservice;
xfire和axis
xfire比axis性能高
axis比xfire响应时间短
一、在eclipse下新建项目工程xfire
二、导入基本的jar包
       commons-codec-1.3.jar
       commons-httpclient-3.0.jar
       commons-logging-1.0.4.jar
       jdom-1.0.jar
       jsr181-api.jar
       spring.jar
       wsdl4j-1.6.1.jar
       xfire-all-1.2.6.jar
       XmlSchema-1.4.7.jar
三、web.xml配置

[html]view plaincopy 
   
 <?xml version="1.0" encoding="UTF-8"?>  
 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">  
   display-name>xfire</>    
   <!-- 定义装入的spring配置文件 -->  
context-param>  
     param-name>contextConfigLocation     param-value      classpath:org/codehaus/xfire/spring/xfire.xml  
      /WEB-INF/xfire-servlet.xml  
<!-- 自动装配配置信息 -->  
listener      listener-class>org.springframework.web.context.ContextLoaderListener<!-- 它主要负责处理由 JavaBean Introspector 功能而引起的缓存泄露 -->  
                      org.springframework.web.util.IntrospectorCleanupListener  
       
   <!-- 注意因为servlet-name为xfire，固xfire配置文件名应该是xfire-servlet.xml -->  
   servlet>    
        servlet-name        servlet-class>org.springframework.web.servlet.dispatcherServletservlet-mappingurl-pattern>*.ws<!-- 配合spring容器中XFire一起工作的Servlet- -->  
>xfireServlet     org.codehaus.xfire.spring.XFireSpringServlet  
>/services/*web-app>  

四、xfire-servlet.xml
copy

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"beans

bean id="baseExporter" class="org.codehaus.xfire.spring.remoting.XFireExporter"

lazy-init="false" abstract="true" property name="serviceFactory" ref="xfire.serviceFactory" />

property name="xfire" ref="xfire" />

property name="outHandlers" list ref bean="domOutHandler" ref bean="soapOutHandler" propertyproperty name="inHandlers"ref bean="domInHandler"bean

bean id="domOutHandler" class="org.codehaus.xfire.util.dom.DOMOutHandler" bean id="soapOutHandler" class="com.bing.webservice.soapOutHandler" bean id="domInHandler" class="org.codehaus.xfire.util.dom.DOMInHandler"

bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping" property name="urlMap" map entry key="/hello.ws" ref bean="helloExporter"entry

bean id="helloExporter" parent="baseExporter"property name="serviceBean" ref="hello" property name="serviceClass" value="com.bing.webservice.IHello" property name="name" value="sayHello"bean id="hello" class="com.bing.webservice.HelloImpl"

五、
接口

[java]copy 
   

package com.bing.webservice;

public interface IHello {
public String sayHello(String name);
}

实现类
copy

class HelloImpl implements IHello {

public String sayHello(String name) {
return "hello! "+ name;
}
}

拦截器
copy

org.codehaus.xfire.MessageContext;

import org.codehaus.xfire.handler.AbstractHandler;
class SoapOutHandler extends AbstractHandler {
void invoke(MessageContext mc) throws Exception {
System.out.println(mc.getCurrentMessage());
}
客户端测试
copy
1. import org.codehaus.xfire.XFire;
2. import org.codehaus.xfire.XFireFactory;
3. import org.codehaus.xfire.client.XFireProxyFactory;
4. import org.codehaus.xfire.service.Service;
5. import org.codehaus.xfire.service.binding.ObjectServiceFactory;
6. class TestClient {
7. static void main(String[] args) {
8. Service serviceModel = new ObjectServiceFactory().create(IHello.class);
9. XFire xfire=XFireFactory.newInstance().getXFire();
10. XFireProxyFactory factory=new XFireProxyFactory(xfire);
11. String serviceUrl = "http://localhost:8080/xfire/services/sayHello";
12. IHello ds= null;
13. try {
14. ds=(IHello)factory.create(serviceModel, serviceUrl);
15. } catch (MalformedURLException e) {
16. e.printstacktrace();
17. }
18. System.out.println(ds.sayHello("Tom"));
19. 另一种方式调用：
  
  client.xml 放在src目录下
