Web Service學習-CXF與Spring整合為JavaEE應用發布WebService(三)
CXF與Spring整合,分兩個方面給大家介紹:
1,在傳統ssh項目基礎上添加Web Service
賦值CXF的jar包
在web.xml配置文件中導入CXF的核心控制器:CXFServlet
在Spring配置文件中導入CXF提供Schema,xml配置文件
在Spring配置文件中使用jaxws:endpoint元素來暴露Web Service
如果要添加攔截器,在jaxws:endpoint元素里添加
inInterceptors,outInterceptors子元素
2,遠程調用Web Service服務(讓Action依賴遠程Web Service的接口)
復制CXF的jar包
在Spring配置文件中導入CXF提供Schema,xml配置文件
在Spring配置文件中使用jaxws:client元素來配置遠程Web Service代理
如果要添加攔截器。在jaxws:client元素里添加
inInterceptors,outInterceptors子元素
第一個方面:提供Web Service的服務
服務端:
項目結構:
在相應的SSH項目中添加CXF的相關jar包:

Web.xml
<?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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext-common.xml</param-value> </context-param> <!--所有來自/*的請求,都交由 CXFServlet來處理--> <servlet> <servlet-name>HelloWorldService</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>HelloWorldService</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> </web-app>
applicationContext-common.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" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 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="helloWorld" class="com.tgb.service.impl.HelloWorldImpl"> <property name="userService" ref="userService"></property> </bean> <!-- 用戶的Service --> <bean id="userService" class="com.tgb.service.impl.UserServiceImpl"> </bean> <!-- implementor指定webservice的服務提供者 --> <!-- address為wsdl的訪問地址 --> <jaxws:endpoint id="hello" implementor="#helloWorld" address="/hjy" > <!-- 添加了2個In攔截器,如果不添加攔截器可直接注釋掉如下代碼 --> <jaxws:inInterceptors> <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"/> <bean class="com.tgb.auth.AuthInterceptor"/> </jaxws:inInterceptors> <!-- 如果要配置Out攔截器,使用outInterceptors --> </jaxws:endpoint> </beans>
以上配置已經完成,對于接口和相應的實現參考之前的博客即可,實現中對于new的內容使用spring管理起來
HelloWorldImpl:
package com.tgb.service.impl; import java.util.Date; import java.util.List; import java.util.Map; import javax.jws.WebService; import com.tgb.domain.Cat; import com.tgb.domain.User; import com.tgb.service.HelloWorld; import com.tgb.service.UserService; @WebService(endpointInterface="com.tgb.service.HelloWorld",serviceName="HelloWorldImpl") public class HelloWorldImpl implements HelloWorld{ private UserService userService; public UserService getUserService() { return userService; } public void setUserService(UserService userService) { this.userService = userService; } public String sayHi(String name) { return name+"您好!現在時間為:"+new Date(); } @Override public List<Cat> getCatsByUser(User user) { //在實際項目中,web service組件自己并不會去實現業務功能 //它只是調用業務邏輯組件的方法來暴露web service // UserService us=new UserServiceImpl(); return userService.getCatsByUser(user); } @Override public Map<String, Cat> getAllCats() { // UserService us=new UserServiceImpl(); return userService.getAllCats(); } }
啟動tomcat服務器:

新建客戶端項目CXF_Spring_Client,生成客戶端代碼:
注意:
有些版本拷貝后,類中的super()會出錯,要加上-frontendjaxws21,參看如上截圖
客戶端調用:
package com.tgb.client; import java.util.List; import org.apache.cxf.endpoint.Client; import org.apache.cxf.frontend.ClientProxy; import com.tgb.auth.AddHeaderInterceptor; import com.tgb.service.Cat; import com.tgb.service.HelloWorld; import com.tgb.service.User; import com.tgb.service.impl.HelloWorldImpl; public class client { public static void main(String[] args){ HelloWorldImpl factory=new HelloWorldImpl(); //此處返回的只是遠程Web Service的代理 HelloWorld hw=factory.getHelloWorldImplPort(); /** * 添加的攔截器 */ Client client=ClientProxy.getClient(hw); //參數為輸入的用戶名,密碼 client.getOutInterceptors().add(new AddHeaderInterceptor("hejingyuan","hjy")); System.out.println(hw.sayHi("hejingyuan")); System.out.println("--------------------------"); User user=new User(); user.setId(20); user.setName("孫悟空"); user.setPass("111"); user.setAddress("花果山"); List<Cat> cats=hw.getCatsByUser(user); for(Cat cat:cats){ System.out.println(cat.getName()); } System.out.println("--------------------------"); System.out.println(hw.getAllCats().getEntry().get(0).getKey()); System.out.println(hw.getAllCats().getEntry().get(0).getValue().getName()); } }

由于我們在服務端添加了攔截器,故客戶端必須要添加相應的攔截器給服務端提供參數,否則客戶端調用失敗

另一個方面:調用遠程的Web Service服務
新建客戶端項目CXF_Spring_Web_Client,生成客戶端代碼

web.xml:
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
applicationContext.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" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 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="listCatsAction" class="com.tgb.action.ListCatsAction"> <property name="helloWorld" ref="helloWorld"></property> </bean> <!-- 配置遠程webservice代理 --> <!-- id="helloWorld"對應 action setHelloWorld() --> <jaxws:client id="helloWorld" serviceClass="com.tgb.service.HelloWorld" address="http://localhost:8080/CXF_Spring_Server/hjy"> <jaxws:outInterceptors> <!-- 配置輸出攔截器 --> <bean class="com.tgb.auth.AddHeaderInterceptor" > <constructor-arg value="hejingyuan"/> <constructor-arg value="hjy"/> </bean> </jaxws:outInterceptors> </jaxws:client> </beans>
Struts.xml:
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <package name="default" namespace="/" extends="struts-default"> <action name="listCats" class="com.tgb.action.ListCatsAction" > <result name="SUCCESS">/WEB-INF/page/listcats.jsp</result> </action> </package> </struts>
調用代碼:
package com.tgb.action; import org.apache.cxf.endpoint.Client; import org.apache.cxf.frontend.ClientProxy; import com.opensymphony.xwork2.ActionSupport; import com.tgb.auth.AddHeaderInterceptor; import com.tgb.service.HelloWorld; public class ListCatsAction extends ActionSupport{ private HelloWorld helloWorld; public HelloWorld getHelloWorld() { return helloWorld; } public void setHelloWorld(HelloWorld helloWorld) { this.helloWorld = helloWorld; } @Override public String execute() throws Exception { /** * 添加的攔截器 */ Client client=ClientProxy.getClient(helloWorld); //參數為輸入的用戶名,密碼 client.getOutInterceptors().add(new AddHeaderInterceptor("hejingyuan","hjy")); helloWorld.sayHi("hejingyuan"); return "SUCCESS"; } }
最終的項目結構:

總結:
以上與Spring的整合,概括的說,在應用Spring的框架過程中,一種是我們如何對外提供服務,另一種是我們如何獲取已經提供好的服務。在整個過程中,只有幾個關鍵點,很簡單,但是要注意jar包的版本問題。
