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:

<!-- 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

<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。
