Servlet Context

Question

我正在编写一个没有自动配置的spring启动应用程序，我遇到以下异常：

java.io.FileNotFoundException: Could not open ServletContext resource [/templates/home.html]
    org.springframework.web.context.support.ServletContextResource.getInputStream(ServletContextResource.java:141)

    javax.servlet.http.HttpServlet.service(HttpServlet.java:729)

可以使用“classpath：templates / home.html”中的WebApplicationContext找到Home.html，但ServletContext无法找到它。我也将WebApplicationContext传递给ServletContext的构造函数。 这是我的配置：

@Configuration
@EnableWebMvc
@ComponentScan(basePackageClasses = {MainController.class})
public class WebConfig
        //extends WebMvcConfigurerAdapter
{

    private static final String UTF8 = "UTF-8";

    @Bean
    @Autowired
    public ViewResolver viewResolver(TemplateEngine engine) {
        ThymeleafViewResolver resolver = new ThymeleafViewResolver();
        resolver.setTemplateEngine(engine);
        resolver.setCharacterEncoding(UTF8);
        return resolver;
    }

    @Autowired
    @Bean
    public TemplateEngine templateEngine(ITemplateResolver resolver) {
        SpringTemplateEngine engine = new SpringTemplateEngine();
        engine.setTemplateResolver(resolver);
        return engine;
    }

    @Bean
    @Autowired
    public ITemplateResolver templateResolver(WebApplicationContext context) {
        SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
        resolver.setApplicationContext(context);
        resolver.setPrefix("templates/");
        resolver.setSuffix(".html");
        resolver.setTemplateMode(TemplateMode.HTML);

        return resolver;
    }

    @Bean
    @Autowired
    public ServletRegistrationBean dispatcherServlet(WebApplicationContext context) {
        ServletRegistrationBean bean = new ServletRegistrationBean(new DispatcherServlet(context), "/");
        bean.setAsyncSupported(true);
        return bean;
    }

    @Bean
    public EmbeddedServletContainerFactory servletContainer() {
        TomcatEmbeddedServletContainerFactory fcty = new TomcatEmbeddedServletContainerFactory();
        return fcty;
    }
}

我的控制器：

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

我的引导：     public class Application扩展了SpringBootServletInitializer {

    public static void main(String[] args) {
        configureBuilder(new SpringApplicationBuilder()).run();
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return configureBuilder(builder);
    }

    private static SpringApplicationBuilder configureBuilder(SpringApplicationBuilder builder) {
        return builder
                .web(true)
                .sources(WebConfig.class);

    }
}

我的目录结构：

resources/
├── static/
└── templates/
    └── home.html
