Question

我使用com.vaadin.tapio.googlemaps.GoogleMap组件从vaadin连接谷歌地图。

我尝试了以下代码。（Vaadin 7.0.2）

public class StoresMainView extends VerticalLayout implements View {

    @Override
    public void enter(ViewChangeEvent event) {
        setSizeFull();


        GoogleMap googleMap = new GoogleMap(new LatLon(-27.47101, 153.02429), 10.0, "");
        googleMap.setSizeFull();
        googleMap.setImmediate(true);
        googleMap.setMinZoom(4.0);
        addComponent(googleMap);


    }

但它在运行时会出现以下错误。我在我的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，我已将Widget设置如下

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

我的DashboardWidgetSet如下

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 1.7.0//EN" "http://google-web-toolkit.googlecode.com/svn/tags/1.7.0/distro-source/core/src/gwt-module.dtd">
<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. 
        This can reduce the GWT compilation time significantly when debugging. The 
        line should be commented out before deployment to production environments. 
        Multiple browsers can be specified for GWT 1.7 as a comma separated list. 
        The supported user agents at the moment of writing were: ie6,ie8,gecko,gecko1_8,safari,opera 
        The value gecko1_8 is used for Firefox 3 and later and safari is used for 
        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>

非常感谢任何帮助。

您需要确保web.xml中的widgetset init-param指向正确的widgetset。默认值不包含有关Google Map组件小部件的任何信息。
