cxf方式

public static Object[] invokeRemoteMethod(String url, String method, Object[] parameters) {
        JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
        if (!url.endsWith("wsdl")) {
            url += "?wsdl";
        }
        org.apache.cxf.endpoint.Client client = dcf.createClient(url);
        try {
            Object[] objects = client.invoke(method, parameters);
            return objects;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

maven引用

<dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-frontend-jaxws</artifactId>
            <version>3.1.5</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.apache.cxf/cxf-core -->
        <dependency>

            <artifactId>cxf-core</artifactId>
            <version>3.1.5</version>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-transports-http</artifactId>
            <version>3.1.5</version>
        </dependency>

缺點是效率低，呼叫速度慢

Xfire方式呼叫

public static String getData(String wsUrl, String invoke, Object[] objParams) throws MalformedURLException, Exception {
        URL url = new URL(wsUrl);
        HttpURLConnection connection = (HttpURLConnection)url.openConnection();
        connection.connect();
        Client client = new Client(connection.getInputStream(), (Class)null);
        client.setProperty("disable-keep-alive", "true");
        client.setProperty("disable.expect-continue", "true");
        client.setUrl(wsUrl);
        Object[] result = client.invoke(invoke, objParams);
        String resultStr = result[0].toString();
        return "".equals(resultStr)?"":resultStr;
    }

maven引用

 <dependency>
             <groupId>org.codehaus.xfire</groupId>
             <artifactId>xfire-all</artifactId>
             <version>${xfire.version}</version>
             <exclusions>
                 <exclusion>
                     <groupId>org.springframework</groupId>
                     <artifactId>spring</artifactId>
                 </exclusion>
             </exclusions>
         </dependency>

缺點是jar包太舊了，很容易與其他包衝突
