【webservice】基于axis2设计带soaphead安全机制的webservice服务端

还是用axis2写的。是先有客户端，再有这个服务端，严格根据客户端的请求报文来写的哦。是否解决了“ 先有鸡还是先有蛋”的问题。。报文的话，请参照我的上一篇博文《【webservice】调试方法篇（二）》，那么，我的编程步骤是这样的。

1、新建java工程，导入axis2的包、dom4j工具包。

2、根据客户端的请求报文上面soap的命名空间，为工程设计包名，因此，本工程的供外部调用类（Server类）的所在包是cn.com.ultrapower.webservice.service。

3、编辑配置文件services.xml如下：

<!-- webservice配置文件   -->
<service name="Prc_Service" >
	<description>
		Please Type your service description here
	</description>
	<messageReceivers>
		<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only" class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
		<messageReceiver  mep="http://www.w3.org/2004/08/wsdl/in-out"  class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
	</messageReceivers>
	<parameter name="ServiceClass">cn.com.ultrapower.webservice.service.Server</parameter>
</service>

5、其他工具类设计：用于加载关于业务码busiKey的map的InitBusiKey.java，

6、其他工具类设计：用于加载user的账号密码、接口权限、接口流量等配置信息的InitUser.java，

下面提供Server类的全部代码：

package cn.com.ultrapower.webservice.service;

import java.io.UnsupportedEncodingException;
import java.util.Calendar;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;

import org.apache.axis2.context.MessageContext;
import org.dom4j.DocumentException;

import cn.com.ultrapower.webservice.service.conf.InitBusiKey;
import cn.com.ultrapower.webservice.service.conf.InitUser;
import cn.com.ultrapower.webservice.service.service.CRBT_Service;
import cn.com.ultrapower.webservice.service.service.ISAG_Service;
import cn.com.ultrapower.webservice.service.service.MMSC_Service;
import cn.com.ultrapower.webservice.service.service.WAPGW_Service;


public class Server{
	//userFlowMap是累加用户在单位时间里对某接口的访问次数
	private static Map<String, Long[]> userFlowMap = new HashMap<String, Long[]>();//String为用户名username，Long[0]为时间，Long[1]为次数
	String responseCode = "";  //查询服务返回的状态码
	String responseXML = "";  //查询服务返回的业务数据
	/*
	 * @para busiKey :     业务平台标识

	 * 定义返回码responseCode：

用axis2用得时间长了，自己也希望有些突破。前阵子重写了这段业务，完全放弃了axis2，直接弄了个servlet，也就是javaweb系统，小巧呢，直接扔到tomcat的webapps就能跑了，用上一篇博文《【webservice】调试方法篇（二）》上面的源码测试，是没问题的。但是，没能及时联系到客户端厂家联调了，因为，我已经申请离职了。今天是在公司的最后一天，就偷闲整理了webservice的系列博文，希望能给大家带来帮助吧。入行不深，且祝我前程似锦吧~
