我在使用weex的web時，把src設為一個變量，在Android端，webView無法載入成功。
we程式碼如下：

    <template>
        <tm-navpage title='{{title}}' listenning_rigth_button_click=true>
            <web id='toomao-web' src='{{src}}' style='width: 750; height: 1206;' onpagefinish='pagefinish'></web>
            <tm-loading if='loading'></tm-loading>
        </tm-navpage>
    </template>


<script>
    data: {
        src: '', // web加载链接
        url: '', // url参数
        userInfo: '',
        title: '',
        loading: true,
        canGoBack: false, // 记录当前webView的加载信息
    },
    created() {
        this.url = decodeURIComponent(getUrlParams(this, 'url'));
    }
</script>

Android端的web實作主要如下:

@Deprecated
    public WXWeb(WXSDKInstance instance, WXDomObject dom, WXVContainer parent, String instanceId, boolean isLazy) {
        this(instance,dom,parent,isLazy);
    }

    public WXWeb(WXSDKInstance instance, WXDomObject dom, WXVContainer parent, boolean isLazy) {
        super(instance, dom, parent, isLazy);
        createWebView();
    }

    protected void  createWebView(){
        mWebView = new WXWebView(getContext());
    }

    @Override
    protected View initComponentHostView(@NonNull Context context) {
        mWebView.setOnErrorListener(new IWebView.OnErrorListener() {
            @Override
            public void onError(String type, Object message) {
                fireEvent(type, message);
            }
        });
        mWebView.setOnPageListener(new IWebView.OnPageListener() {
            @Override
            public void onReceivedTitle(String title) {
                if (getDomObject().getEvents().contains(Constants.Event.RECEIVEDTITLE)) {
                    Map<String, Object> params = new HashMap<>();
                    params.put("title", title);
                    fireEvent(Constants.Event.RECEIVEDTITLE, params);
                }
            }

            @Override
            public void onPageStart(String url) {
                if ( getDomObject().getEvents().contains(Constants.Event.PAGESTART)) {
                    Map<String, Object> params = new HashMap<>();
                    params.put("url", url);
                    fireEvent(Constants.Event.PAGESTART, params);
                }
            }

            @Override
            public void onPageFinish(String url, boolean canGoBack, boolean canGoForward) {
                if ( getDomObject().getEvents().contains(Constants.Event.PAGEFINISH)) {
                    Map<String, Object> params = new HashMap<>();
                    params.put("url", url);
                    params.put("canGoBack", canGoBack);
                    params.put("canGoForward", canGoForward);
                    fireEvent(Constants.Event.PAGEFINISH, params);
                }
            }
        });
        return mWebView.getView();
    }

    @Override
    public void destroy() {
        super.destroy();
        getWebView().destroy();
    }

    @Override
    protected boolean setProperty(String key, Object param) {
        switch (key) {
            case Constants.Name.SHOW_LOADING:
                Boolean result = WXUtils.getBoolean(param,null);
                if (result != null)
                    setShowLoading(result);
                return true;
            case Constants.Name.SRC:
                String src = WXUtils.getString(param,null);
                if (src != null)
                    setUrl(src);
                return true;
        }
        return super.setProperty(key,param);
    }

    @WXComponentProp(name = Constants.Name.SHOW_LOADING)
    public void setShowLoading(boolean showLoading) {
        getWebView().setShowLoading(showLoading);
    }

    @WXComponentProp(name = Constants.Name.SRC)
    public void setUrl(String url) {
        if (TextUtils.isEmpty(url) || getHostView() == null) {
            return;
        }
        if (!TextUtils.isEmpty(url)) {
            loadUrl(getInstance().rewriteUri(Uri.parse(url), URIAdapter.WEB).toString());
        }
    }

    public void setAction(String action) {
        if (!TextUtils.isEmpty(action)) {
            if (action.equals(GO_BACK)) {
                goBack();
            } else if (action.equals(GO_FORWARD)) {
                goForward();
            } else if (action.equals(RELOAD)) {
                reload();
            }
        }
    }
    

    private void fireEvent(String type, Object message) {
        if (getDomObject().getEvents().contains(Constants.Event.ERROR)) {
            Map<String, Object> params = new HashMap<>();
            params.put("type", type);
            params.put("errorMsg", message);
            fireEvent(Constants.Event.ERROR, params);
        }
    }

    private void loadUrl(String url) {
        getWebView().loadUrl(url);
    }

    private void reload() {
        getWebView().reload();
    }

    private void goForward() {
        getWebView().goForward();
    }

    private void goBack() {
        getWebView().goBack();
    }

    private IWebView getWebView() {
        return mWebView;
    }

問題

在調試的過程中，發現setProperty方法只會走一次，就是在設定的時候， 當src從新賦值之後，web並不會去刷新url從新載入。求如何實現當src變化 時，web可以去從新加載，

嘗試過refreshData方法，發現也不會呼叫。

    @Override
    public void refreshData(WXComponent component) {
        super.refreshData(component);
        component.getDomObject().getAttrs();
    }
