java - 如何通过Vaadin导入外部主题并将其与注释一起使用？

假设我有两个项目。 CompanyApp和CompanyVaadinThemes。

CompanyApp是正常的Vaadin 7.7.3应用程序。 CompanyVaadinThemesis只是将Vaadin 7.7.3主题编译成一个jar。

CompanyVaadinThemes.jar

source/main/resources/VAADIN/themes/mytheme
    mytheme.scss
    styles.scss
    ...

CompanyApp.war

pom.xml
    ...
    <dependency>
        <groupId>com.vaadin</groupId>
        <artifactId>vaadin-themes</artifactId>
        <version>${vaadin.version}</version>
    </dependency>
    <dependency>
        <groupId>com.company</groupId>
        <artifactId>company-vaadin-themes</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>


...

UI.java

    @SpringUI
    @Theme("mytheme")
    public class CompanyUI extends UI {

但是，我似乎无法弄清楚如何进行这项工作。如果我将实际代码从CompanyVaadinThemes.jar复制到主CompanyApp，一切都很好。我可以使用“ mytheme”，“ valo”等

但是我想将实际主题保留在一个单独的项目中，以便将来的项目可以简单地将其添加为依赖项。

这是CompanyVaadinThemes的pom：

最佳答案

主题中的VAADIN文件夹应位于jar文件的根目录中：

VAADIN/themes/mytheme
    mytheme.scss
    styles.scss
