基于mvn调用由java开发的第三方服务调用代码

1.pom.xml添加依赖

 <!--HttpClient組建配置-->
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.5.5</version>
        </dependency>
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>fluent-hc</artifactId>
            <version>4.5.5</version>
        </dependency>
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpcore</artifactId>
            <version>4.4.9</version>
        </dependency>

　　

2.新增java类文件

import org.apache.http.util.EntityUtils;

            // 释放资源

3.调用示例

3.1请求报文

<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:web="http://webservices.b.com">  
   <soapenv:Header/>  
   <soapenv:Body>  
      <web:order soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">  
         <in0 xsi:type="web:OrderRequest">  
            <mobile xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">?</mobile>

            <productCode xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">?</productCode>  
         </in0>  
      </web:order>  
   </soapenv:Body>  
</soapenv:Envelope> 

3.2调用示例

                + "   </soapenv:Body>" + "</soapenv:Envelope>";  
        String postUrl = "http://localhost:8080/services/WebServiceFromB";  
        //采用SOAP1.1调用服务端，这种方式能调用服务端为soap1.1和soap1.2的服务 

　　　　　　HttpUtil.doPostSoap1_1(postUrl, orderSoapXml, ""); 

　　　　　　HttpUtil.doPostSoap1_1(postUrl, querySoapXml, "");

　　　　　//有的webservice地址需要提供?wsdl才能调用
　　　　  //调用方式比如:HttpUtil.doPostSoap1_1(postUrl+"?wsdl", orderSoapXml, "接口名");
