java调用webservice WSDL形式接口之apache axis方式调用（一）

1. 先说一下什么是webservice

webservice的 发布一般都是使用WSDL（web service descriptive language）文件的样式来发布的，在WSDL文件里面，包含这个webservice暴露在外面可供使用的接口。

（1）WebService是一个SOA（面向服务的编程）的架构，它是不依赖于语言，不依赖于平台，可以实现不同的语言间的相互调用，通过Internet进行基于Http协议的网络应用间的交互。  
（2）WebService实现不同语言间的调用，是依托于一个标准，webservice是需要遵守WSDL（web服务定义语言）/SOAP（简单请求协议）规范的。

2. 下面是介绍如何使用axis调用webservice

（1）先从官网下载axis相关jar包，地址：http://axis.apache.org/axis/

官方要求引入如下jar包（将lib下的jar引入即可）

*  axis-*<version>*/lib/axis.jar
 *  axis-*<version>*/lib/jaxrpc.jar
 *  axis-*<version>*/lib/saaj.jar
 *  axis-*<version>*/lib/commons-logging-*<version>*.jar
 *  axis-*<version>*/lib/commons-discovery-*<version>*.jar
 *  axis-*<version>*/lib/wsdl4j-*<version>*.jar

我在项目中实际用到的最少jar如下：

H:\\libs\\axis.jar  
H:\\libs\\jaxrpc.jar  
H:\\libs\\commons-logging-1.0.4.jar  
H:\\libs\\commons-discovery-0.2.jar  
H:\\libs\\wsdl4j-1.5.1.jar

（2）具体代码实现

package ic;
    
    import javax.xml.rpc.ParameterMode;
    
    import org.apache.axis.client.Call;
    import org.apache.axis.client.Service;
    import org.apache.axis.encoding.XMLType;
    
    public class ICServiceTest1 {
    
    	public static void main(String[] args) {
    
    		try {
    
    			String endpoint = "http://localhost:3000/hy/gw/queryConsignOrder?wsdl";
    
    			Service service = new Service();
    			Call call = (Call) service.createCall();
    			call.setTargetEndpointAddress(endpoint);
    			// WSDL里面描述的接口名称(要调用的方法)
    			call.setOperationName("getLisQueryConsignOrder");
    			// 接口方法的参数名, 参数类型,参数模式  IN(输入), OUT(输出) or INOUT(输入输出)
    			call.addParameter("icSystem", XMLType.XSD_STRING, ParameterMode.IN);
    			call.addParameter("companyFlag", XMLType.XSD_STRING, ParameterMode.IN);
    			call.addParameter("consignOrderNo", XMLType.XSD_STRING, ParameterMode.IN);
    			call.addParameter("orderNo", XMLType.XSD_STRING, ParameterMode.IN);
    			// 设置被调用方法的返回值类型
    			call.setReturnType(XMLType.XSD_STRING);
    			//设置方法中参数的值
    			Object[] paramValues = new Object[] {"4PL","NJHY,NJHF","TC201309172206",""};
    			// 给方法传递参数，并且调用方法
    			String result = (String) call.invoke(paramValues);	
    	
    			System.out.println("result is " + result);
    		} catch (Exception e) {
    			e.printStackTrace();
    		}
    
    	}
    
    }

今天在调用webserivce接口的时候出现了如下异常

这种异常不是程序抛出来的，是由服务器抛出的，所以在程序里抓不到异常。

出现此种问题要注意一下是否已经把接口中用到的jar包加进了服务器中或者项目中。

我用的webservice接口的服务器为TOMCAT，此时需要将webservice接口中用到的jar到全部放到tomcat的lib下，这样做后，异常解决
