我是 Spring Boot 的新手，正在努力将一个简单的 HTML Web 应用程序 (AngularJS) 部署到 Tomcat 8。这个 Web 应用程序仅提供一些 HTML/CSS/JS 内容，没有对后端的 REST 调用。它是使用 Webpack“编译”的——这会生成 JS/CSS 包和一个通过以下方式指向它们的 index.html 文件：<script> / <link>标签——并且已经在 ExpressJS 和带有嵌入式 tomcat 的 Spring Boot 上进行了测试，并且按预期工作。但沿着独立 WAR 的道路并部署到 Tomcat 8 似乎并不能正常工作。
对于 Spring Boot 项目，我已将所有 HTML/CSS/JS 文件包含在src/main/resources/public文件夹（无子文件夹）并且还配置了pom.xml如下（基本配置）：

“主”类：
package com.example.my.app;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
@SpringBootApplication
public class MyAppApplication extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(MyAppApplication.class);
}
public static void main(String[] args) {
SpringApplication.run(MyAppApplication.class, args);
}
}
以下是我用于进行 Tomcat 部署的步骤：
-
mvn clean package生成 WAR
- 将WAR复制到path/to/tomcat8/webapp
- 启动Tomcat
-
http://localhost:8080/my-app http://localhost:8080/my-app=> 自动加载index.html
不幸的是我看到的都是 404 错误，因为它找不到一些 JS/CSS 文件。我缺少什么配置吗？
Updated:
这是index.html 文件（通过Webpack 自动生成）：
<!doctype html>
<html>
<head>
<base href="/">
<meta charset="utf-8">
<title>My App</title>
<meta name="description" content="">
<meta name="viewport" content="width=device-width">
<link rel="icon" type="image/png" href="./assets/images/favicon.ico" />
<link href="/main-aa49893f83cc830596563d81f09a9611.css" rel="stylesheet"><link href="/main-5949f1f257a55a77e48bc4ab62fbc99a.css" rel="stylesheet"></head>
<body ng-app="myapp">
<ui-view></ui-view>
<script type="text/javascript" src="vendor-353ddb48f4ffe6546d59.js"></script><script type="text/javascript" src="app-353ddb48f4ffe6546d59.js"></script></body>
</html>
以下是我访问 Chrome Web Inspector 时看到的错误localhost:8080/my-app/index.html:
http://localhost:8080/main-5949f1f257a55a77e48bc4ab62fbc99a.css Failed to load resource: the server responded with a status of 404 (Not Found)

还有一件事我忘了提。当我使用生成战争时mvn clean package， src/main/resources/public 下的所有文件都放入WEB-INF/classes/resource子文件夹。根据研究，这些文件不是公开可见的（即，如果我尝试访问 localhost:8080/my-app/foo.css，它将给出 404）。这就是index.html文件无法“看到”它所依赖的JS/CSS文件的原因吗？
