webservice 小记

需求：

实现在A系统展示B数据库中的数据,利用spring3.0 + axis2

实现思路：

客户端：发送xml 参数,请求服务器端方法;接收来自服务器端的数据,保存到本地数据库。

服务器端：执行方法,返回数据到客户端。

实现过程客户端:
package com.thunisoft.sy.webService;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Iterator;
import java.util.List;
import javax.xml.namespace.QName;
import javax.xml.rpc.ParameterMode;

private SyDaoImpl syDao;

sb.append("<fybh>").append("-1").append("</fybh>");
sb.append("<jglx>1,2,3,4</jglx>");
sb.append("</params>");
logger.info("调用传入参数：" + sb.toString());
Service service = new Service();
try {
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(url);

"queryParam",// 服务器端方法参数

call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);  //服务器端返回数据类型
call.setUseSOAPAction(true);  
// call.setSOAPActionURI("http://vms.service.business.vms.thunisoft.com/insertVisitorInfo");
Object [] obj = new Object[] {sb.toString()};
String result = (String) call.invoke(obj);
logger.info("服务器端接口返回结果:" + result);

客户端文件cong.properties 部分配置

#服务器端接口url
npWebService.url=http://172.16.215.216:8080/fy2000Interface/services/fy2000Service?wsdl

#每天执行时间
npTodayService.cron=*/20 * * * * ?

#注：客户端请求服务器端的url规则为,服务器端项目发布路径/web.xml中<url-pattern>的值/server-config.wsdd中自定义服务service name的值?wsdl

客户端文件applicationContetxt.xml 部分配置
