Java 如何将vaadin 7与Google地图连接

我使用com.vaadin.tapio.googlemaps.GoogleMap组件从vaadin连接到Google地图

我尝试了以下代码。（Vaadin 7.0.2）

但运行时会出现以下错误。我在pom中添加了依赖项

Widgetset does not contain implementation for com.vaadin.tapio.googlemaps.GoogleMap. Check its component connector's @Connect mapping, widgetsets GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package, you might want to refer to add-on instructions.

在我的web.xml中，我定义了小部件集，如下所示

 <init-param>
        <param-name>widgetset</param-name>
        <param-value>com.client.DashboardWidgetSet</param-value>
    </init-param>

<module>
    <inherits name="com.vaadin.DefaultWidgetSet" />

    <inherits name="org.vaadin.cssinject.Cssinject_addonWidgetset" />
    <!--  -->

    <set-configuration-property name="devModeRedirectEnabled"
        value="true" />

    <!-- Uncomment the following to compile the widgetset for one browser only.

        line should be commented out before deployment to production environments.

        webkit based browsers including Google Chrome. -->
    <!-- <set-property name="user.agent" value="safari"/> -->

    <!-- WidgetSetOptimizer -->

    <inherits name="org.vaadin.easyuploads.Widgetset" />

    <inherits name="com.vaadin.tapio.googlemaps.WidgetSet" />

</module>

widgetset
com.client.DashboardWidgetSet

我的仪表板设置如下

 <init-param>
        <param-name>widgetset</param-name>
        <param-value>com.client.DashboardWidgetSet</param-value>
    </init-param>

非常感谢您的帮助。

您需要确保web.xml中的widgetset init参数指向正确的widgetset。默认设置不包含有关Google Map组件小部件的任何信息。

在将附加依赖项添加到pom后，您是否重新编译widgetset？是的，我重新编译了。您可以创建一个测试项目来隔离问题吗？也许是在github？嗨Jonas，我在我的帖子中添加了我的init参数。至少不能立即发现任何奇怪的东西。widgetset编译没有错误吗？尝试向widgetset编译器参数添加-pretty，以确保它不会跳过任何可能的错误。
