java调用webService客户端的实现

[小马子]

哪们大侠给指点一下：我这里用apach 的axis2调用别人给的一个webService接口，调用方法如下
package com.cstc.service;

import java.net.URL;

import javax.xml.namespace.QName;
import javax.xml.rpc.ParameterMode;

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;

import com.cstc.util.DESCoder;


public class QueryService {
public void queryPersonInfoByName(String idno,String cid){
System.out.println("idno+cid"+idno+" "+cid);
try{
String sKey = "CSgjjWeb";
String endpoint = "http://www.csgjj.com.cn:9001/QueryService.asmx?WSDL";
Service service = new Service();
Call call = (Call)service.createCall();
call.setTargetEndpointAddress(new URL(endpoint));
call.setOperationName(new QName("http://www.csgjj.com.cn:9001/WebService", "QueryPersonalInfo"));
call.addParameter(new QName("http://www.csgjj.com.cn:9001/WebService", "strPersonalName"), XMLType.XSD_STRING, ParameterMode.IN);
call.addParameter(new QName("http://www.csgjj.com.cn:9001/WebService","strIdno"), XMLType.XSD_STRING, ParameterMode.IN);
call.addParameter(new QName("http://www.csgjj.com.cn:9001/WebService","strCustomerID"), XMLType.XSD_STRING, ParameterMode.IN);
call.setUseSOAPAction(true);
call.setSOAPActionURI("http://www.csgjj.com.cn:9001/WebService/QueryPersonalInfo");
call.setReturnType(XMLType.XSD_STRING);
String strPersonalName = DESCoder.EncryptAsDoNet(new String("唐晓晖".getBytes("UTF-8")),sKey);
String strIdno = DESCoder.EncryptAsDoNet(idno,sKey);
String strCustomerID = DESCoder.EncryptAsDoNet(cid,sKey);
Object[] params = new Object[3];
params[0] = strPersonalName;
params[1] = strIdno;
params[2] = strCustomerID;
String res = (String)call.invoke(params);
String resDe = DESCoder.DecryptDoNet(res,sKey);
// System.out.println("Right: " + "IbN+8kIFNo/w2Q9GnBI82w==");
// System.out.println("Current: " + (String)params[0]);
System.out.println(resDe);
System.out.println("over queryService");

}catch (Exception ex){
System.out.println("Error: " + ex.getMessage());
}
System.out.println("over catch hou");
}
public static void main(String args[]){
QueryService qs =new QueryService();
qs.queryPersonInfoByName("430104197105050796","12580");
}
}
在这里用的main方法进行的调用，是可以查到想要的数据的。但是如果在servlet中进行调用返回的数据是空的，也没有任何错误提示，代码如下：
public class InsuranceServlet extends HttpServlet {


public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {


QueryService qs =new QueryService();
qs.queryPersonInfoByName("430104197105050796","12580");
System.out.println("over InsuranceServlet");
}

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}

}
这样查到的结果是空，这是为什么呀？没有错误提示，程序已经执行完毕，高手请指点，谢啦！

DESCoder 是一个加密和解密的类代码如下：
public abstract class DESCoder {
/*
* 加密字符串
*/
public static String EncryptAsDoNet(String message, String key) throws Exception {
……

帅哥 你这个类里面代码是不是没贴完？
String resDe = DESCoder.DecryptDoNet(res,sKey); 这句报错
DecryptDoNet 方法没有啊

[s478853630]

在浏览器输入这个地址：http://localhost:8088/bank/services/bankService?wsdl
得到以下结果，说明这个webservice是可用的！

然后在另外一个项目中测试调用：

Java codepackage com.axis2.test;

import javax.xml.namespace.QName;
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;
import com.axis2.entity.MyBank;

/**
* 调用axis2的webservice
* */
public class TestAxis2 {

private static TestAxis2 bean = new TestAxis2();
private String serviceUrl = "http://localhost:8088/bank/services/bankService";// webservice的url(这个url必须是通的,否则调用失败)
private String nameSpace = "http://service.bank.com";// webservice的命名空间(其实就是协议和包名的倒写)

/**
* @see 调用axis2的webservice
* @param method 发布方的方法名
* @param args 方法中的参数列表
* @return MyBank
* */
@SuppressWarnings("unchecked")
public MyBank useAxis2(String method, Object[] args) {
MyBank bank = null;
RPCServiceClient client=null;
try {
client = new RPCServiceClient();
Options option = client.getOptions();
EndpointReference erf = new EndpointReference(serviceUrl);
option.setTo(erf);
QName name = new QName(nameSpace, method);
Class[] returnTypes = new Class[] { MyBank.class };
Object[] response = client.invokeBlocking(name, args, returnTypes);
bank = (MyBank) response[0];
} catch (Exception e) {
e.printStackTrace();
}finally{
try {
client.cleanupTransport();
} catch (AxisFault e) {
e.printStackTrace();
}
}
return bank;
}

public static void main(String[] args) {
MyBank fromBack = new MyBank();
MyBank toBank = new MyBank();
MyBank bank = bean.useAxis2("transition", new Object[]{ fromBack, toBank });
System.out.println(bank.getPrompt());
}

}



运行完毕，控制台没有出现异常，而且打印我想要的结果，
这说明axis2发布和调用webservice都成功了！

[howtodown]

不容易啊

[for_my_chen]

这么多代码。。。。。苦逼的程序员啊，，，，耗费精力啊

[s478853630]

呵呵！
这下代码的原作并不是鄙人，鄙人也是从一个前辈那里学来的。
像这些代码最好去学习前辈的，要等自己写出来，够呛！！！

建议lz最好是去下载demo，因为运行这段代码需要20个jar的支持，少一个都不行！

[cscript]

不需要通用的话，直接用HttpConnection或HttpClient模拟提交行了，用那些axis或cxf 太麻烦了

[小马子]

并没有解决我的问题呀？我的那种方式用main方法测试也是可行的，有正确的数据返回，可是为什么用Servlet调用就返回不了结果呢？哪位大师帮帮忙给看下啦，很急的！（补充：我用java远程donet的webService接口）

[s478853630]

main方法可以运行就意味着只要有java代码的任何角落都可以运行,
记得大一初学java时，老师是这么说的！

不知道你那是个啥情况，最好能上门服务！！呵呵！

[fanket2002]

为什么你的servlet里面没有初始化方法和销毁方法？

[fanket2002]

DESCoder 能否把这个类贴上来？

[小马子]

[Quote=引用 9 楼 的回复:]

[/Quote]
DESCoder 是一个加密和解密的类代码如下：
public abstract class DESCoder {
/*
* 加密字符串
*/
public static String EncryptAsDoNet(String message, String key) throws Exception {
//产生与.net 对应的加密des + base64 加密串
//message = java.net.URLEncoder.encode(message, "ascii");

Cipher cipher = Cipher.getInstance("DES/CBC/PKCS5Padding");
DESKeySpec desKeySpec = new DESKeySpec(key.getBytes("GB2312"));
SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
SecretKey secretKey = keyFactory.generateSecret(desKeySpec);
IvParameterSpec iv = new IvParameterSpec(key.getBytes("GB2312"));
cipher.init(Cipher.ENCRYPT_MODE, secretKey, iv);
byte[] encryptbyte = cipher.doFinal(message.getBytes());
BASE64Encoder base64Encoder = new BASE64Encoder();
//base64Encoder.encode(encryptbyte);
return base64Encoder.encode(encryptbyte);
//toHexString(encryptbyte).toUpperCase();

}
}
麻烦帮忙看下，谢啦！

[cscript]

既然main函数没有错误，建议楼主在servlet运行debug跟踪下，找出问题

[小马子]

我跟过的，问题应该是出在加密这里，就是说从main里边和servlet里边传过来的中文名字是相同的测字，但加密出来的结果是不一样的，这一点我非常不能理解，麻烦帮忙看下

[chenw323]

使用axis2调用wenbservice 可以直接用wsdl2java把wsdl转成本地代码
比自己写代码方便多了啊

我也遇到同样的问题，在servlet中加密的结果和main中不一样
