收集整理的這篇文章主要介紹了
WebServices中使用cxf开发日志拦截器以及自定义拦截器
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
首先下載一個cxf實例，里面包含cxf的jar包。我下的是apache-cxf-2.5.9
1、為什么要設置攔截器？
為了在webservice請求過程中,能動態操作請求和響應數據,?CXF設計了攔截器.
2、攔截器分類
1.?按所處的位置分：服務器端攔截器，客戶端攔截器
2.?按消息的方向分：入攔截器，出攔截器
3.?按定義者分：系統攔截器，自定義攔截器
3、攔截器API
Interceptor(攔截器接口)
AbstractPhaseInterceptor(自定義攔截器從此繼承)
LoggingInInterceptor(系統日志入攔截器類)
LoggingOutInterceptor(系統日志出攔截器類)
4、編寫實現攔截器
??使用日志攔截器，實現日志記錄
–?LoggingInInterceptor
–?LoggingOutInterceptor
??使用自定義攔截器，實現用戶名與密碼的檢驗
–?服務器端的in攔截器
–?客戶端的out攔截器
–?benjamin/123456
系統日志攔截器代碼實現：
Server：
SEI：
[html]?view plaincopy print?
package?com.wiseweb.ws;????import?javax.jws.WebMethod;??import?javax.jws.WebService;????/**???*?SEI???*?@author?piqiu???*???*/??@WebService??public?interface?HelloWS?{????????@WebMethod??????public?String?sayHello(String?name)?;??}?? SEI的實現：
[html]?view plaincopy print?
package?com.wiseweb.ws;????import?javax.jws.WebService;????/**???*?SEI的實現???*?@author?piqiu???*???*/??@WebService??public?class?HelloWSImpl?implements?HelloWS?{????????@Override??????public?String?sayHello(String?name)?{??????????System.out.println("server?sayHello():"?+?name);??????????return?"Hello:?"?+?name;??????}????}?? ServerTest：
[html]?view plaincopy print?
package?com.wiseweb.ws.server;????import?java.util.List;????import?javax.xml.ws.Endpoint;????import?org.apache.cxf.interceptor.Interceptor;??import?org.apache.cxf.interceptor.LoggingInInterceptor;??import?org.apache.cxf.interceptor.LoggingOutInterceptor;??import?org.apache.cxf.jaxws22.EndpointImpl;??import?org.apache.cxf.message.Message;????import?com.wiseweb.ws.HelloWSImpl;????/**???*?發布webservice???*?@author?piqiu???*???*/??public?class?ServerTest?{????????public?static?void?main(String[]?args)?{??????????String?address?=?"http://10.211.55.3:8888/day01_ws/hellows"?;??????????Endpoint?endpoint?=?Endpoint.publish(address,?new?HelloWSImpl())?;??????????EndpointImpl?endpointImpl?=?(EndpointImpl)?endpoint?;????????????????????List<Interceptor<??extends?Message>>?inInterceptors?=?endpointImpl.getInInterceptors()?;??????????inInterceptors.add(new?LoggingInInterceptor())?;????????????????????List<Interceptor<??extends?Message>>?outInterceptors?=?endpointImpl.getOutInterceptors()?;??????????outInterceptors.add(new?LoggingOutInterceptor())?;????????????????????System.out.println("發布webservice成功!");??????}??}?? Client： 把下載下來的apache-cxf-2.5.9的bin目錄配置到系統環境變量的path中去，以便可以在cmd中執行bin中的bat文件
在cmd中輸入wsdl2java SEI地址就可以生成客戶端代碼了，同樣也可以使用wsimport命令。
