我正在编写一个部署在Tomcat上的Spring MVC应用程序.请参阅以下最小,完整且可验证的示例

public class Application extends AbstractAnnotationConfigDispatcherServletInitializer {
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[] { };
    }
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[] { SpringServletConfig.class };
    }
    protected String[] getServletMappings() {
        return new String[] { "/*" };
    }
}

哪里SpringServletConfig是

@Configuration
@ComponentScan("com.example.controllers")
@EnableWebMvc
public class SpringServletConfig {
    @Bean
    public InternalResourceViewResolver resolver() {
        InternalResourceViewResolver vr = new InternalResourceViewResolver();
        vr.setPrefix("/WEB-INF/jsps/");
        vr.setSuffix(".jsp");
        return vr;
    }
}

最后,我有一个@Controller包com.example.controllers

@Controller
public class ExampleController {
    @RequestMapping(path = "/home", …

我正在尝试使用gradle,spring boot和spring mvc以最简单的视图解析器和html制作"hello world"应用程序.

我从thymeleaf spring boot示例开始,我只想删除thymeleaf,使用纯html和InternalResourceViewResolver创建一个更简单的mvc应用程序.我有一个greeting.html我想要服务,它位于src/main/webapp/WEB-INF.当我运行应用程序时,我得到了

No mapping found for HTTP request with URI [/WEB-INF/greeting.html] in DispatcherServlet with name 'dispatcherServlet'

这是一个常见的错误,网上有很多答案,但似乎没有任何帮助.

这是我的Application.java

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

这是我的GreetingController.java

@Controller
public class GreetingController {
    @RequestMapping("/greeting")
    public String greeting() {
        return "greeting";
    }
}

这是我的MvcConfiguration.java

@Configuration
@EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter{
    @Bean
    public ViewResolver getViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/");
        resolver.setSuffix(".html");
        return resolver;
    }
}

我用它来运行它 …
