CXF動態調用執行個體

 

對於webservice,我個人用CXF比較多,所以下面寫個文章教教入門,囉嗦話不多說

先寫個對象

package com.shadow.extras.cxf;import java.io.Serializable;import javax.xml.bind.annotation.XmlAccessType;import javax.xml.bind.annotation.XmlAccessorType;@XmlAccessorType(XmlAccessType.FIELD)@SuppressWarnings("serial")public class User implements Serializable {public Integer id;private String username;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}}

然後寫服務端介面

package com.shadow.extras.cxf;import javax.jws.WebParam;import javax.jws.WebService;@WebServicepublic interface UserWebService {public User queryUser(@WebParam(name = "user") User user,@WebParam(name = "id") Integer id);public Integer queryCount(@WebParam(name = "count") Integer count);}

接著實現我們剛剛寫的介面

package com.shadow.extras.cxf;import javax.jws.WebService;@WebService(endpointInterface = "com.shadow.extras.cxf.UserWebService")public class UserWebServiceImpl implements UserWebService {@Overridepublic User queryUser(User user, Integer id) {System.out.println("目前使用者名: " + user.getUsername());System.out.println("id參數: " + id);return user;}@Overridepublic Integer queryCount(Integer count) {return count;}}

上面的步驟完成後就開始配置我們的xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws"xmlns:cxf="http://cxf.apache.org/core"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://cxf.apache.org/jaxws       http://cxf.apache.org/schemas/jaxws.xsd"><!--***注意*** 手動添加的內容： xmlns:jaxws="http://cxf.apache.org/jaxws"http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"--><import resource="classpath:META-INF/cxf/cxf.xml" /><import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /><import resource="classpath:META-INF/cxf/cxf-servlet.xml" /><bean id="userWebService" class="com.shadow.extras.cxf.UserWebServiceImpl" /><jaxws:endpoint id="queryService" implementor="#userWebService"address="/query" /></beans>

最後就寫個main測試效果

package com.shadow.extras.cxf;import java.lang.reflect.Method;import org.apache.cxf.endpoint.Client;import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;public class CXFClient {public static void main(String[] args) {JaxWsDynamicClientFactory factory = JaxWsDynamicClientFactory.newInstance();Client client = factory.createClient("http://localhost/services/query?wsdl");Object user = null;try {user = Thread.currentThread().getContextClassLoader().loadClass("com.shadow.extras.cxf.User").newInstance(); // 擷取參數對象的執行個體Method method = user.getClass().getMethod("setUsername", String.class); // 通過方法設定對象的屬性值method.invoke(user, "ssss");Object[] result = client.invoke("queryUser", user, 50); // 按照方法的參數來提供值if(result != null && result.length > 0){System.out.println(result[0].getClass().getMethod("getUsername").invoke(result[0])); // 通過getUsername來擷取對象的username屬性}Object[] result2 = client.invoke("queryCount", 101);if(result2 != null && result2.length > 0){System.out.println(result2[0]); // 基本類型返回就直接輸出,或者強轉對應類型}} catch (Exception e) {e.printStackTrace();}}}
