大家好，我正在使用spring boot和vaadin为大学创建一个webapp。我想做的就是改变背景颜色。添加src / man / webapp / VAADIN / themes / myTheme
然后我
myTheme.scss
@import "../valo/valo";
@mixin myTheme {
@include valo;
}
我还有trie valo.scss
styles.scss
@import "mytheme.scss";
.mytheme {
@include mytheme;
}
然后我在我的ui中调用@theme，但是我收到了编译错误，我已经尝试了各种方法来解决这个问题。
valo文件夹似乎是空的

有人可以帮助我。我真的不喜欢使用它。感谢

您需要在styles.scss中观看字符大小写。它应该如下：
@import "myTheme.scss";
.myTheme {
@include myTheme;
}
注意资本＆＃34; T＆＃34;。还要确保您的UI类使用以下标注：
@Theme("myTheme")
另请注意，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。
祝你好运。

尝试在src / main / resources / VAADIN / themes / yourtheme
中添加主题问候
