1.下载axis

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

2.核心代码

核心代码：

package webserviceClinet;

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;

public class webserviceClient
{
    public static void main(String[] args)
    {
        try
        {   
            //直接运行java Application  
            String endpoint = "http://127.0.0.1:8088/myStr.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(new QName("urn:myStr", "myStrCat"));
            // 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("str1In", XMLType.XSD_STRING, ParameterMode.IN);//该参数必须与wsdl中一致，否则可能传输过去为空值
            call.addParameter("str2In", XMLType.XSD_STRING, ParameterMode.IN);//该参数必须与wsdl中一致，否则可能传输过去为空值
            call.addParameter("paramOut", XMLType.XSD_STRING, ParameterMode.OUT);//该参数必须与wsdl中一致
            // 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
            String str = "{\"userID\":\"123456\",\"userName\":\"杰克\"}";//userID
            //String strParam = new String(str.getBytes(Charset.forName("UTF-8")));
            Object[] paramValues = new Object[] {"123","456"}; 
            // 给方法传递参数，并且调用方法  
            String result = (String)call.invoke(paramValues);
            //打印结果
            System.out.println("C++ result: " + result);
        }
        catch (Exception  e) 
        {   
            e.printStackTrace();   
        }
    }
}

WSDL 文件如下：

<definitions xmlns:tns="http://localhost:8088/myStr.wsdl" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:ns="urn:myStr" xmlns:SOAP="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:HTTP="http://schemas.xmlsoap.org/wsdl/http/" xmlns:MIME="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:DIME="http://schemas.xmlsoap.org/ws/2002/04/dime/wsdl/" xmlns:WSDL="http://schemas.xmlsoap.org/wsdl/" xmlns="http://schemas.xmlsoap.org/wsdl/" name="myStr" targetNamespace="http://localhost:8088/myStr.wsdl">

<port name="myStr" binding="tns:myStr">

</port>
</service>
</definitions>

3.运行结果

4.注意事项

4.1入口参数

入口参数必须与wsdl一致，否则会出现传输空值的问题
