您好，我正在使用Spring Boot和vaadin为大学创建一个Webapp。我要做的就是改变背景色。通过添加src / man / webapp / VAADIN / themes / myTheme
然后我有
myTheme.scss
@import "../valo/valo";
@mixin myTheme {
@include valo;
}
我也有valo.scss
styles.scss
@import "mytheme.scss";
.mytheme {
@include mytheme;
}
然后，我在ui中调用
@theme，但是遇到编译错误，我尝试了所有解决方法。valo文件夹似乎为空

有人可以帮我吗。我真的不喜欢使用它。谢谢
最佳答案
您需要注意styles.scss中的字符大小写。应该如下：
@import "myTheme.scss";
.myTheme {
@include myTheme;
}
注意大写字母“ T”。还要确保您的UI类带有以下注释：
@Theme("myTheme")
还要注意，您不需要
valo文件夹，也不会在项目中创建或填充一个文件夹。导入的valo SCSS文件和包含的valo mixin打包在vaadin-themes jar中。祝你好运。
