CXF學習-與Spring結合：使用其他程序提供的web service 接口

package crazyit.call.cxf;

import java.util.HashMap;
import java.util.Map;

import com.opensymphony.xwork2.ActionSupport;

import cxf.ws.Cat;
import cxf.ws.Entry;
import cxf.ws.HelloWorld;
import cxf.ws.StringCat;

public class ListCatAction extends ActionSupport {
	
	private HelloWorld hw;

	public HelloWorld getHw() {
		return hw;
	}

	public void setHw(HelloWorld hw) {
		this.hw = hw;
	}
	
	private Map<String,Cat> cats=new HashMap<String, Cat>();

	public Map<String, Cat> getCats() {
		return cats;
	}

	public void setCats(Map<String, Cat> cats) {
		this.cats = cats;
	}
	
	public String execute(){
		StringCat sc=hw.getAllCats();
		for(Entry entry:sc.getEntries()){
			cats.put(entry.getKey(), entry.getValue());
		}
		setCats(cats);
		return SUCCESS;
	}
	
}

步驟：

1、讓Action依賴遠程web service接口；

1）添加一個action 在action裏面調用webService代理

2）在spring配置文件裏面

2、複製CXF核心JAR包；
3、在Spring配置文件中導入CXF提供Schema、xml配置；
4、在Spring配置文件裏面配置 jaxws:client, 配置遠程Web Service代理；
5、如果要添加攔截器，在jaxws:client裏面添加inInterceptors及outInterceptors元素。

攔截器

package crazyit.call.cxf.auth;

import java.util.List;

import javax.xml.namespace.QName;

import org.apache.cxf.binding.soap.SoapMessage;
import org.apache.cxf.headers.Header;
import org.apache.cxf.helpers.DOMUtils;
import org.apache.cxf.interceptor.Fault;
import org.apache.cxf.phase.AbstractPhaseInterceptor;
import org.apache.cxf.phase.Phase;
import org.w3c.dom.Document;
import org.w3c.dom.Element;

public class AuthOutInterceptor extends AbstractPhaseInterceptor<SoapMessage> {

	private String userId;
	
	private String userPass;
	
	public AuthOutInterceptor(String userId,String userPass){
		super(Phase.PREPARE_SEND);//在準備發送SOAP消息時,啓用該攔截器
		this.userId=userId;
		this.userPass=userPass;
	}

	@Override
	public void handleMessage(SoapMessage msg) throws Fault {
		List<Header> headers=msg.getHeaders();
		//創建document對象
		Document doc=DOMUtils.createDocument();
		
		Element ele=doc.createElement("authHeader");
		//此處創建的元素，應該按照服務器那邊的要求
		Element idEle=doc.createElement("userId");
		Element passEle=doc.createElement("userPass");
		
		idEle.setTextContent(userId);
		passEle.setTextContent(userPass);
		
		ele.appendChild(idEle);
		ele.appendChild(passEle);
		//把ele包裝成header
		headers.add(new Header(new QName("fkjava"), ele));
	}
