java - Spring Boot 和 React 无法加载 index.html

Question

我正在尝试使用 create-react-app 和 Spring Boot 创建一个简单的 Web 应用程序，但是 spring 在资源中找不到 index.html。

React 的 build 文件夹被 maven-resources-plugin 复制到 target:

<plugin>
    <artifactId>maven-resources-plugin</artifactId>
           ...
            <phase>package</phase>
                <goals>
                    <goal>copy-resources</goal>
                </goals>
                ...
                <outputDirectory>${basedir}/target/classes</outputDirectory>
                    <resources>
                        <resource>
                            <directory>src/main/app/build</directory>
                            <filtering>true</filtering>
                        </resource>
                    </resources>
                ...     
</plugin>

这是我的项目结构:

Controller :

@Controller
public class BasicController {
   @RequestMapping(value = "/", method = RequestMethod.GET)
   public String index() {
      return "index";
   }
}

获取对 localhost:8080 的请求返回 404。你能指出我错在哪里吗？

更新:

通过将 maven 插件中 React 的构建输出目录更改为 ${basedir}/src/main/resources/META-INF/resources 并且 return "index" 到 return index.html。

Answer 1

好吧，这可能不是您问题的准确答案，但我会尝试示例 from the docs .

Spring Boot will automatically add static web resources located within any of the following directories:

/META-INF/resources/

/resources/

/static/

/public/

In the case of the Consuming a RESTful Web Service with jQuery guide, we included index.html and hello.js files in the /public/ folder. This means that not only does Spring Boot offer a simple approach to building Java or Groovy apps, you can also use it to easily deploy client-side JavaScript code and test it within a real web server environment!

只需将 CRA 构建目录的内容复制到 Spring Boot public 目录(确保 index.html 在 /public/index.html )。

如果可行，则尝试自动化该过程。
