我无法访问我的静态html文件在Spring Boot 。我尝试了不同的配置,但我仍然得到资源找不到错误
首先,我尝试使用JSP,它不工作,然后我切换到thymeleaf它确实工作,这是因为JPS的限制,最后我使用html。
我的控制器工作正常,我使用RestControllerController进行单独的测试运行,它们工作正常,thymeleaf需要在类级别声明RequestMapping才能工作,但在html的情况下,我被卡住了,然后我发现了这个

spring.mvc.view.prefix: /resources/**
spring.web.resources.chain.strategy.content.enabled=true
spring.web.resources.chain.strategy.content.paths=/**
spring.mvc.contentnegotiation.favor-parameter=true

字符串
我能够访问静态资源,但没有控制器,他们没有与控制器和我得到资源找不到错误。
为了您的信息,我尝试将html文件放置在main/webapps/WEB-INF/,**/resources/static/,/resources/templates/**中,目前我能够访问它们,因为它们位于resources/static/中,并且我在/resources/public/error/404.html中有404.html每次使用端点时,我都会获得404.html,但控制器仍然无法工作
这是我的控制器

@Controller
public class AssignmentController {

    @GetMapping("home")
    public String home() {
        return "home";
    }

    @GetMapping("/")
    public String main() {
        return "index";
    }

    @GetMapping("login")
    public String myLogin() {
        return "login";
    }         
}


要清楚的是,有效的URL是http://localhost:8080/index. html/,应该手动输入,但当我使用http://localhost:8080/home, http://localhost:8080/索引或http://localhost:8080/时,我得到错误页面
而我的最后一次尝试是使用webmvcconfigurer

@Override
        public void configureViewResolvers(ViewResolverRegistry registry) {
            InternalResourceViewResolver resourceViewResolver = new InternalResourceViewResolver();
            resourceViewResolver.setPrefix("/resources/**/");
            resourceViewResolver.setSuffix(".html");
            registry.viewResolver(resourceViewResolver);
        }


这是日志

对于像这样的基本应用程序,当您使用@Controller并将html文件放置在resources/static/文件夹中时,问题可能会重现

我认为你在你的项目中有一个错误的配置。服务静态文件是最简单的事情。
我尝试了你的github示例(禁用数据库,因为没有身体有你的数据库)和HTML文件可用

我用thymeleaf开始了一个旧的模板

我在静态文件夹中添加了一个foo.txt(../src/main/resources/static/foo.txt



重新启动后,文件准备就绪:
