使用CXF调用WSDL

简介

时隔多年，再次遇到需要调用WebService的业务，对方给予的wsdl说明文档还是内网的链接，并且设有基础访问权限，即在浏览器打开wsdl链接时需要输入【用户名+密码】登录后方可查看wsdl文档，这需要设置代理（我使用putty完成了代理），本文只记录使用org.apache.cxf调用wsdl的过程

附一张putty的下载链接：

步骤一 ：添加org.apache.cxf的maven引用

        
        
            org.apache.cxf
            cxf-rt-frontend-jaxws
            3.5.2
        
        
            org.apache.cxf
            cxf-rt-transports-http
            3.5.2
        
        

步骤二：访问WSDL

/**
     * 打开WSDL文件
     * @return
     */
    private static Bus openWSDL(){
        Bus bus = BusFactory.getThreadDefaultBus();
        bus.setExtension((name, address, httpConduit) -> {
            //设置访问wsdl所需的用户名和密码
            final AuthorizationPolicy authorization = new AuthorizationPolicy();
            authorization.setUserName("username");
            authorization.setPassword("password");
            httpConduit.setAuthorization(authorization);
            final HttpAuthSupplier supplier = new DefaultBasicAuthSupplier();
            httpConduit.setAuthSupplier(supplier);
            //设置service中location的映射代理IP和端口 
            final HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
            httpClientPolicy.setProxyServer("127.0.0.1");
            httpClientPolicy.setProxyServerPort(50000);
            httpClientPolicy.setAllowChunking(false);
            httpClientPolicy.setConnectionTimeout(50000);
            httpClientPolicy.setReceiveTimeout(50000);
            httpConduit.setClient(httpClientPolicy);
        }, HTTPConduitConfigurer.class);
        return bus;
    }

步骤三：获取WSDL文档内容

/**
     * 获取WSDL内容
     * @return
     */
    private static Map getWSDLContent() {
        Map wsdl = new HashMap<>();
        try {
            Bus bus = openWSDL();
            ClassLoader loader = Gmm1020Server.class.getClassLoader();
            // 创建动态客户端
            JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance(bus);
            Client client = dcf.createClient("你的wsdl地址",
                    new QName("wsdl中的targetNamespace", "wsdl:service的name"),
                    loader,
                    new QName("wsdl中的targetNamespace", "HTTP_Port"));
            QName qName = new QName("wsdl中的targetNamespace", "wsdl:operation的name");
            List partInfos = client.getEndpoint()
                    .getService().getServiceInfos().get(0)
                    .getBinding(new QName("wsdl中的targetNamespace", "wsdl:binding的name"))
                    .getOperation(qName)
                    .getInput().getMessageParts();
            wsdl.put("client",client);
            wsdl.put("qname",qName);
            wsdl.put("messagePartInfo",partInfos);
        } catch (Exception e) {
            throw new WebServiceException(e);
        }
        return wsdl;
    }

注意：Bus引用的是上一个方法

Bus bus = openWSDL();

步骤四：调用远程接口（远程过程调用）

/**
     * 调用远程过程
     */
    public static void call(Map map) {
        Map wsdl = getWSDLContent();
        Client client = (Client) wsdl.get("client");
        List partInfos = (List) wsdl.get("messagePartInfo");
        QName qName = (QName) wsdl.get("qname");

        String clazzName = partInfos.get(0).getTypeClass().getName();
        try {
            Object requestParamObject = Thread.currentThread().getContextClassLoader().loadClass(clazzName).newInstance();
            Field[] fields = requestParamObject.getClass().getDeclaredFields();
            for (Field field : fields) {
                //如果是泛型
                boolean b = field.getGenericType() instanceof ParameterizedType;
                if(b && field.getType() == List.class){
                    Type[] types = ((ParameterizedType)field.getGenericType()).getActualTypeArguments();
                    for (Type type : types) {
                        Class aClass = (Class) type;
                        Object obj = aClass.newInstance();
                        List
