（二）CXF使用HANDLER处理头信息

使用CXF可以很方便的在客户端使用Handler增加头信息，只需在调用服务前设置到proxyBean中即可；

在服务端也可以很方便的使用Handler来解析头信息，只需要在开启服务前设置到factoryBean中即可；

接口

package com.hqh.ws.cxf;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

@WebService
public interface IMyService {

	@WebMethod
	@WebResult(name="sayResult")

实现类

package com.hqh.ws.cxf;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService(endpointInterface="com.hqh.ws.cxf.IMyService")
public class MyServiceImpl implements IMyService {

解析头信息的Handler

public class LicenseHandler implements SOAPHandler<SOAPMessageContext> {

	@Override
	public boolean handleMessage(SOAPMessageContext context) {
		boolean out = (Boolean)context.get(SOAPMessageContext.MESSAGE_OUTBOUND_PROPERTY);
		try {
			//进入的消息，则检查HEADER
			if(!out) {
				SOAPEnvelope env = context.getMessage().getSOAPPart().getEnvelope();
				SOAPHeader header = env.getHeader();
				SOAPBody body = env.getBody();
				if(header == null) {
					return true;
				}
				//Iterator<SOAPHeaderElement> iter = header.getChildElements();
				Iterator<SOAPHeaderElement> iter = header.extractAllHeaderElements();
				String license = "";
				while(iter.hasNext()) {
					SOAPHeaderElement headerEle = iter.next();
					if(headerEle.getLocalName().equals("license")) {
						license = headerEle.getTextContent();
						System.out.println("获取到头信息："+license);
						break;
					}
				}
				System.out.println(license);
			}
		} catch (SOAPException e) {
			e.printStackTrace();
		}
		return true;
	}

	@Override
	public boolean handleFault(SOAPMessageContext context) {
		return false;
	}

	@Override
	public void close(MessageContext context) {
		
	}

	@Override
	public Set<QName> getHeaders() {
		return null;
	}

}

 

开启服务

package com.hqh.ws.cxf;
