Spring 启动应用程序显示 index.html 的 404

Question

我有一个 Spring 启动应用程序和一个位于 src/main/resources/static 中的静态 index.html 文件

我的控制器很直接，看起来像这样

@Controller
@Log4j
public class StartController {

    @Autowired
    OwnerRepository ownerRepository;

    @RequestMapping("/")
    public String index() {
        return "index";


    }

}

我唯一的配置是主要配置，当我点击 URL 时，它只有 @SpringBootApplication 我得到 404，根据我的理解，在启动时的日志中不需要进一步的配置，我看到以下内容

请求 [/index] 的 URI 模板变量为 {}

这是我的 POM

Answer 1

On your pom.xml i didn't see any template engine like Thymeleaf, Velocity ecc but you have spring-boot-starter-web, so basically you resource folder its configurated, but you should put your file index.html on templates folder. Static folder serve to contain your asset files.

如果您在本地工作，请尝试： localhost:8080/或localhost:8080/alquifacil/假设您使用端口 8080 或在 pom.xml 中添加模板引擎依赖项，如 Thymeleaf

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
