我是网络开发的新手，我已经扫描了大部分关于此的问题，但我的情况有所不同。 Here is my project structure
我将前端文件夹放在项目根文件夹中，所以当我构建Spring项目时，我使用maven构建Angular项目并将其移动到target/classes/static
这是我的maven插件
<build>

<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>

<resource>
<directory>${basedir}/angular-client/dist</directory >
</resource>
</resources>

这可以在我当地的笔记本电脑上使用。

我知道原因是当heroku构建项目时路径会改变，但是如何解决这个问题，并且有些人会告诉我一些关于heroku构建项目时会发生什么的事情？
答案 0 :(得分：0)
好的，我发现原因是，angular-client是项目的子模块，我从.git和git push项目中删除子模块配置，它可以工作。
