问题很简单,但我花了2天时间尝试部署我的应用程序。到目前为止还没有。

如本文所述: Spring Boot Executable jar structure “您应该将静态资源放在src/main/resources中。”

所以把css放在这里: src/main/resources/styles.css

在Vaadin文档中(非常关注如何打包…),我将css导入如下:

@StyleSheet("styles.css")

资料来源: https://vaadin.com/docs/v11/flow/importing-dependencies/tutorial-include-css.html

然后我打包我的项目:

 mvn clean package -Pproduction

[ERROR] Failed to execute goal com.vaadin:vaadin-maven-plugin:11.0.0:package-for-production (default) on project importparcoursup: Execution default of goal com.vaadin:vaadin-maven-plugin:11.0.0:package-for-production failed: An import that ends with 'styles.css' cannot be resolved: the corresponding file 'C:\Workspace\lasteclipeandjava10\parcoursup\target\frontend\styles.css' was not found.
[ERROR] Double check the corresponding import and verify the following:
[ERROR] * the import string is correct
[ERROR] * the file imported is either present in 'frontend://' directory of the project or in one of the project WebJar dependencies or in one of the regular jar dependencies
[ERROR] * if the file is present in one of the regular jar dependencies, it should be located in `META-INF/resources/frontend` directory in the jar
