cxf 和 httpclient 客户端调用 webservice 接口

一、cxf 生成 webservice 客户端

1、接口路径 http://ws.webxml.com.cn/WebServices/WeatherWS.asmx 

2、进入你需要放置 webservice 客户端代码的包，进入这个包所在的系统路径，进入 cmd

3、执行命令 wsimport -keep http://ws.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl 或者 wsdl2java -client http://ws.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl 

　　3.1、如果报错信息如下：具有相同名称“xxx”的类/接口已经使用。

　　wsdl2java -client http://ws.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl 

　　改为 

　　wsdl2java -client -autoNameResolution http://ws.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl 

4、spring 整合 cxf

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
    <jaxws:client id="userClient"
        serviceClass="com.java.webservice.service.impl.ITianQi"   <!--生成的接口-->
        address="http://ws.webxml.com.cn/WebServices/WeatherWS.asmx">       
    </jaxws:client>
</beans> 

二、httpclient 调用 webservice

public static String getXML() {
    StringBuffer sb = new StringBuffer();
    sb.append("<?xml version='1.0' encoding='utf-8'?>"
            + "<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'>"
            + "<soap:Body>" + "<getMobileCodeInfo xmlns='http://WebXml.com.cn/'>"
            + "<mobileCode>string</mobileCode>" + " <userID>string</userID>" + "</getMobileCodeInfo>"
            + "</soap:Body>" + "</soap:Envelope>");
    return sb.toString();
}

static int socketTimeout = 30000;// 请求超时时间
static int connectTimeout = 30000;// 传输超时时间

public static String doPost() {
    String postUrl = "http://ws.webxml.com.cn/WebServices/WeatherWS.asmx";
    String soapAction = "";
    String soapXml = getXML();
    String retStr = "";
    // 创建HttpClientBuilder
    HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
    // HttpClient
    CloseableHttpClient closeableHttpClient = httpClientBuilder.build();
    HttpPost httpPost = new HttpPost(postUrl);
    // 设置请求和传输超时时间
    RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(socketTimeout)
            .setConnectTimeout(connectTimeout).build();
    httpPost.setConfig(requestConfig);
    try {
        httpPost.setHeader("Content-Type", "application/soap+xml;charset=UTF-8");
        httpPost.setHeader("SOAPAction", soapAction);
        StringEntity data = new StringEntity(soapXml, Charset.forName("UTF-8"));
        httpPost.setEntity(data);
        CloseableHttpResponse response = closeableHttpClient.execute(httpPost);
        HttpEntity httpEntity = response.getEntity();
        if (httpEntity != null) {
            // 打印响应内容
            retStr = EntityUtils.toString(httpEntity, "UTF-8");
        }
        // 释放资源
        closeableHttpClient.close();
    } catch (Exception e) {
    }
    return retStr;
}
