### 1、xfire接口代码 ###

import org.codehaus.xfire.client.Client;
    import org.w3c.dom.Document;
    import javax.xml.transform.OutputKeys;
    import javax.xml.transform.Transformer;
    import javax.xml.transform.TransformerFactory;
    import javax.xml.transform.dom.DOMSource;
    import javax.xml.transform.stream.StreamResult;
    import java.io.StringWriter;
    import java.net.URL;
    
    public class Test {
        private static String WSDL = "";
    
        static{
            WSDL = "http://localhost:8080/userWebService?wsdl";
        }
    
        public static void main(String[] args){
            getAllUsers();
        }
    
        public static void getAllUsers() {
            String result = "";
            try {
                Client client = new Client(new URL(WSDL));
    
                Object[] results = client.invoke("getUserByName", new Object[]{"李四"});
    
             //   Object[] results = client.invoke("getAllUsers", new Object[]{});
    
                Document d = (Document)results[0];
    
                System.out.println(toFormatedXML(d));
    
                System.out.println(result);
    
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    
        public static String toFormatedXML(Document doc) throws Exception {
            TransformerFactory transFactory = TransformerFactory.newInstance();
            Transformer transFormer = transFactory.newTransformer();
            transFormer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
            DOMSource domSource = new DOMSource(doc);
            StringWriter sw = new StringWriter();
            StreamResult xmlResult = new StreamResult(sw);
            transFormer.transform(domSource, xmlResult);
            return sw.toString();
    
        }
    }

### 2、报错信息 ###

org.codehaus.xfire.fault.XFireFault: Unmarshalling Error: 意外的元素 (uri:"http://xxx.com/", local:"arg0")。所需元素为<{}arg0>

    	at com.chinaoly.Test.getAllUsers(Test.java:33)
    	at com.chinaoly.Test.main(Test.java:22)

### 3、解决办法 ###

需要修改服务段接口代码，增加@WebParam参数部分内容

import javax.jws.WebParam;
    import javax.jws.WebService;
    import java.util.List;
    
    @WebService
    public interface IUserWebService {
        
        User getUserByName(@WebParam(name="userName",targetNamespace = "http://xx.com/") String userName);
    
        List<User> getAllUsers();
    
    }

### 4、解决办法2 ###

如果服务端是别人提供的，可能不好要求别人改代码，所以只能修改自己的客户端代码，改成cfx方式

import org.apache.cxf.endpoint.Client;
    import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
    import org.eclipse.jetty.util.ajax.JSON;
    import java.net.URLDecoder;
    
    public class TestCFX {
        public static void main(String args[]){
    
            JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
            Client client = dcf.createClient("http://localhost:8080/userWebService?wsdl");
            String result = "";
    
            try{
                Object[] objects = client.invoke("getUserByName","李四");
                result = URLDecoder.decode(JSON.toString(objects),"utf-8");
                System.out.println(result);
    
                objects = client.invoke("getAllUsers");
                result = URLDecoder.decode(JSON.toString(objects),"utf-8");
                System.out.println(result);
    
            }catch(Exception e){
                e.printStackTrace();
            }
        }
    }

### 5、尝试kettle的web service组件 ###

流程：生成查询参数，查询之后把结果写到文本文件

![20191023094908241.png][]

webservice查询配置：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3p3YWh1dA_size_16_color_FFFFFF_t_70][]

刚开始报错，错误信息如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3p3YWh1dA_size_16_color_FFFFFF_t_70 1][]

没拷贝全的信息如下：

2019/10/23 09:52:40 - Web 服务查询.0 - Response body: 
    <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body><soap:Fault><faultcode>soap:Server</faultcode>
    <faultstring>The given SOAPAction http://chinaoly.com/getAllUsers does not match an operation.</faultstring>
    </soap:Fault>
    </soap:Body>
    </soap:Envelope>

查找的解决办法，也是修改服务端的代码，添加 @WebMethod部分的信息

import javax.jws.WebMethod;
    import javax.jws.WebService;
    import java.util.List;
    
    @WebService
    public interface IUserWebService {
        //@WebParam(name="userName",targetNamespace = "http://xx.com/")
        @WebMethod(action="http://xx.com/getUserByName")
        User getUserByName( String userName);
    
        @WebMethod(action="http://xx.com/getAllUsers")
        List<User> getAllUsers();
    
    }
