WebService學習筆記-添加攔截器到基於Spring的Webservice

服務器端目錄結構如圖。在上一篇博文中的項目的基礎上添加了一個interceptor類。

CheckUserInterceptor.java攔截器

package com.umgsai.interceptors;

import javax.xml.namespace.QName;

import org.apache.cxf.binding.soap.SoapMessage;
import org.apache.cxf.headers.Header;
import org.apache.cxf.interceptor.Fault;
import org.apache.cxf.phase.AbstractPhaseInterceptor;
import org.apache.cxf.phase.Phase;
import org.w3c.dom.Element;
//檢查用戶的 攔截器
public class CheckUserInterceptor extends AbstractPhaseInterceptor<SoapMessage> {

	public CheckUserInterceptor() {
		super(Phase.PRE_PROTOCOL);// 準備協議化時攔截
	}

	@Override
	public void handleMessage(SoapMessage message) throws Fault {
		Header header = message.getHeader(new QName("atguigu"));
		if (header != null) {
			Element element = (Element) header.getObject();
			String username = element.getElementsByTagName("username").item(0).getTextContent();
			String password = element.getElementsByTagName("password").item(0).getTextContent();
			if (username.equals("umgsai")&&password.equals("123456")) {
				System.out.println("經過攔截器...");
				return;
			}
		}
		//不能經過
		System.out.println("沒有經過攔截器");
		throw new Fault(new RuntimeException("用戶名或密碼不正確"));
	}

}

beans-xml配置攔截器
