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);
-
- call.setOperationName("getLisQueryConsignOrder");
-
- 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);
-
- call.setReturnType(XMLType.XSD_STRING);
-
- Object[] paramValues = new Object[] {"4PL","NJHY,NJHF","TC201309172206",""};
-
- 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
