     * @param clazz     返回参数类型
     * @param <T>       接收参数类型
     * @return
     * @throws Exception
     */

        String[] values = new String[params.size()];
        for (int i = 0; i < params.size(); i++) {
            call.addParameter(new QName(namespace, keys.get(i)), XMLType.XSD_STRING, ParameterMode.IN);
            values[i] = params.get(keys.get(i)).toString();
        }

        call.registerTypeMapping(clazz,
                new QName(namespace, method),
                new BeanSerializerFactory(clazz, new QName(namespace, method)),

        if (!StringUtils.isEmpty(actionURI)) {
            call.setUseSOAPAction(true);
        }

        if (clazz.getName().contains("java.lang.String")) {
            call.setReturnType(XMLType.XSD_STRING);
        } else {
            call.setReturnClass(clazz);
        }

        return (T) call.invoke(values);
    }

        JaxWsDynamicClientFactory clientFactory = JaxWsDynamicClientFactory.newInstance();
        Client client = clientFactory.createClient(url);
        Object[] objects = client.invoke(new QName(namespace, method), params.toString());
