Java 调用 WebService 服务的 3 种方式

虽然 WebService 这个框架已经过时，但是有些公司还在使用，在调用他们的服务的时候就不得不面对各种问题，本篇文章总结了最近我调用他司 WebService 的心路历程。3 种方式可以分别尝试，哪种能通用哪个。

## 1. HttpClient ##

依赖：

<dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <optional>true</optional>
            </dependency>
            
            <dependency>
                <groupId>org.apache.httpcomponents.client5</groupId>
                <artifactId>httpclient5</artifactId>
                <version>5.1.3</version>
            </dependency>

代码：

import lombok.extern.slf4j.Slf4j;
    import org.apache.http.impl.client.HttpClientBuilder;
    import org.apache.http.impl.client.CloseableHttpClient;
    import org.apache.http.client.methods.HttpPost;
    import org.apache.http.entity.StringEntity;
    import org.apache.http.HttpEntity;
    
    @Slf4j
    public class HttpClientUtil {
        
        /**
         * HttpClient 调用 WebService
         * @param wsUrl webService地址，格式：http://ip:port/xxx/xxx/soap?wsdl
         * @param json格式的入参
         * @return
         */
        public static String callServiceHC(String wsUrl, String jsonStr) {
        
            String xml = createSoapContent(jsonStr);
            String returnDatabase = doPostSoap(wsUrl, xml, "");
            log.info("returnDatabase===>{}", returnDatabase);
            return returnDatabase;
        }
        
        /**
         * 根据拼接 xml 字符串
         * @param input
         * @return
         */
        public static String createSoapContent(String jsonStr) {
        
            log.info("开始拼接请求报文");
            //开始拼接请求报文
            StringBuilder stringBuilder = new StringBuilder();
            stringBuilder.append("<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:zys=\"http://www.chenjy.com.cn/\">\n");
            stringBuilder.append("<soapenv:Header/>\n");
            stringBuilder.append("<soapenv:Body>\n");
            stringBuilder.append("<cjy:CallInterface>\n");
            stringBuilder.append("<cjy:msgHeader><![CDATA[\n");
            stringBuilder.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n");
            stringBuilder.append("<root>\n");
            stringBuilder.append("<serverName>getInfo</serverName>\n");
            stringBuilder.append("<format>xml</format>\n");
            stringBuilder.append("<callOperator>测试</callOperator>\n");
            stringBuilder.append("<certificate>AcsaoP21Lxw5KAoQu6SLs624bhGjwNL0DzxsQ9a7B/HbqNsPPcA==</certificate>\n");
            stringBuilder.append("</root>\n");
            stringBuilder.append("]]></cjy:msgHeader>\n");
            stringBuilder.append("<cjy:msgBody><![CDATA[\n");
            stringBuilder.append( jsonStr+ "\n");
            stringBuilder.append("]]></cjy:msgBody>\n");
            stringBuilder.append("</cjy:CallInterface>\n");
            stringBuilder.append("</soapenv:Body>\n");
            stringBuilder.append("</soapenv:Envelope>");
            log.info("拼接后的参数"+stringBuilder.toString());
            return stringBuilder.toString();
        }
    
        /**
         * HTTPClient 调用 WebService
         * @param url

         */
        public static String doPostSoap(String url, String soap, String SOAPAction) {
        
            //请求体
            String retStr = "";
            // 创建HttpClientBuilder
            HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
            // HttpClient
            CloseableHttpClient closeableHttpClient = httpClientBuilder.build();
            HttpPost httpPost = new HttpPost(url);
            try {
        
                httpPost.setHeader("Content-Type", "text/xml;charset=UTF-8");
                httpPost.setHeader("SOAPAction", SOAPAction);
                StringEntity data = new StringEntity(soap,
                        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) {
        
                e.printStackTrace();
            }
            return retStr;
        }
    }

注意：拼接 xml 字符串的时候要根据实际的 WebService 地址拼接，可在 soapui 中导入 wsurl 获取到入参，如下：

把这些参数全部拼接进去：

## 3. cxf ##

因为我用 cxf 调不通，所以就在这里就直接奉上其他博主的调用案例：
