【整理】用XFire+Spring搭建WebService(Hello简单版+实用版)

2010-11-05 21:34

首先我们需要下载jar包. 如果你有或是正在用MyEclipse的话（我的MyEclipse 版本是5.5.1 GA）就非常容易了。直接新建web项目上右键-->MyEclipse-->Add Web Service Capabilities -->Finish（因为会默认XFIRE 1.2 Core Libraries） 如果你要下载，就去这里：xfire.codehaus.org/Download 下载最新的版本 xfire-distribution-1.2.6.zip (点此直接下载)。 官网还有XFire的源码，日后可以研究使用。 下载下来的zip里面examples-->spring就是一个简单的XFire+Spring的WebService(Echo例子)。 把lib,modules下我们需要的jar包添加到 WEB-INF - lib 目录（Spring的jar包自然要添加进去）。 commons-codec-1.3.jar commons-httpclient-3.0.jar commons-logging-1.0.4.jar jdom-1.0.jar spring.jar stax-api-1.0.1.jar wsdl4j-1.6.1.jar xfire-all-1.2.6.jar   先给大家看下我们搭建WebService完后的项目结构图（Eclipse版本）。此外我把这个演示项目连同源码一起发布了一个war包。 下载地址：code.google.com/p/jivam-utils/downloads/list 中的 webservice.war（点此直接下载）。 一、在src下面建立service的包，新建一个接口HelloService。 package service; public interface HelloService { public String sayHello(String name); } 二、建立HelloService的接口实现类HelloServiceImpl。 package service; public class HelloServiceImpl implements HelloService { public String sayHello(String name) {    return "Hello,"+name+" !"; } } 三、修改WEB-INF下的web.xml <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4">     <context-param>         <param-name>contextConfigLocation</param-name>         <param-value>/WEB-INF/applicationContext.xml         classpath:org/codehaus/xfire/spring/xfire.xml</param-value>     </context-param>     <listener>         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>     </listener>     <servlet>         <servlet-name>xfire</servlet-name>         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>     </servlet>     <servlet-mapping>         <servlet-name>xfire</servlet-name>         <url-pattern>/WebService/*</url-pattern>     </servlet-mapping> </web-app> 四、修改WEB-INF下的applicationContext.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans>     <bean id="helloBean" class="service.HelloServiceImpl"/> </beans> 五、在WEB-INF下新建xfire-servlet.xml。（要结合上面的各个xml理解其含义，其实很简单） <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans>     <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">         <property name="urlMap">             <map>                 <entry key="/HelloService">                     <ref bean="hello"/>                 </entry>             </map>         </property>     </bean>         <bean id="hello" class="org.codehaus.xfire.spring.remoting.XFireExporter">         <property name="serviceFactory">             <ref bean="xfire.serviceFactory"/>         </property>         <property name="xfire">             <ref bean="xfire"/>         </property>         <property name="serviceBean">             <ref bean="helloBean"/>         </property>         <property name="serviceClass">             <value>service.HelloService</value>         </property>     </bean> </beans> 这时候WebService就搭建完成了，那怎么测试呢？ 请点击http://localhost:8080/webservice/WebService/HelloService?wsdl 看到下面的情况你就成功了： <?xml version="1.0" encoding="UTF-8" ?> - <wsdl:definitions targetNamespace="http://service" xmlns:soapenc12="http://www.w3.org/2003/05/soap-encoding" xmlns:tns="http://service" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap11="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soapenc11="http://schemas.xmlsoap.org/soap/encoding/" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"> - <wsdl:types> - <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="http://service"> - <xsd:element name="sayHello"> - <xsd:complexType> - <xsd:sequence> <xsd:element maxOccurs="1" minOccurs="1" name="in0" nillable="true" type="xsd:string" /> </xsd:sequence> </xsd:complexType> </xsd:element> - <xsd:element name="sayHelloResponse"> - <xsd:complexType> - <xsd:sequence> <xsd:element maxOccurs="1" minOccurs="1" name="out" nillable="true" type="xsd:string" /> </xsd:sequence> </xsd:complexType> </xsd:element> </xsd:schema> </wsdl:types> - <wsdl:message name="sayHelloRequest"> <wsdl:part name="parameters" element="tns:sayHello" /> </wsdl:message> - <wsdl:message name="sayHelloResponse"> <wsdl:part name="parameters" element="tns:sayHelloResponse" /> </wsdl:message> - <wsdl:portType name="HelloServicePortType"> - <wsdl:operation name="sayHello"> <wsdl:input name="sayHelloRequest" message="tns:sayHelloRequest" /> <wsdl:output name="sayHelloResponse" message="tns:sayHelloResponse" /> </wsdl:operation> </wsdl:portType> - <wsdl:binding name="HelloServiceHttpBinding" type="tns:HelloServicePortType"> <wsdlsoap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http" /> - <wsdl:operation name="sayHello"> <wsdlsoap:operation soapAction="" /> - <wsdl:input name="sayHelloRequest"> <wsdlsoap:body use="literal" /> </wsdl:input> - <wsdl:output name="sayHelloResponse"> <wsdlsoap:body use="literal" /> </wsdl:output> </wsdl:operation> </wsdl:binding> + <wsdl:service name="HelloService"> - <wsdl:port name="HelloServiceHttpPort" binding="tns:HelloServiceHttpBinding"> <wsdlsoap:address location="http://localhost:8080/webservice/WebService/HelloService" /> </wsdl:port> </wsdl:service> </wsdl:definitions> 那下面我们来写个客户端（客户端需要commons-httpclient-3.0.jar，lib里面就有）。src下面新建test目录，新建HelloClient ，因为客户端和服务器端我写在同样的一个项目里，所以 HelloService 我直接引用了，实际项目中是分开的2个项目，此时就需要服务器的项目吧 HelloService 接口，如果有交互的实体类，则连同接口一起打成JAR包，放到客户端的目录下，然后就可以引用了。       package test; import java.net.MalformedURLException; import org.codehaus.xfire.XFire; import org.codehaus.xfire.XFireFactory; import org.codehaus.xfire.client.XFireProxyFactory; import org.codehaus.xfire.service.Service; import org.codehaus.xfire.service.binding.ObjectServiceFactory; import service.HelloService; public class HelloClient{ public static void main(String[] args) {    Service srvcModel = new ObjectServiceFactory().create(HelloService.class);    XFire xfire = XFireFactory.newInstance().getXFire();    XFireProxyFactory factory = new XFireProxyFactory(xfire);    String serviceUrl = "http://localhost:8080/webservice/WebService/HelloService";    HelloService hs = null;     try {      hs = (HelloService)factory.create(srvcModel, serviceUrl);     } catch (MalformedURLException e) {      e.printStackTrace();     }     System.out.println(hs.sayHello("Jivam")); } } =========项目过滤器中怎么安全的过滤WebService请求======== 如果web.xml中 xFire的url-pattern地址是 <url-pattern>/WebService/*</url-pattern> 那么在相应的Filter中应这样过滤才是安全的： HttpServletRequest req = (HttpServletRequest)request; if(req.getServletPath().equals("/WebService")){         chain.doFilter(request, response); }
