我的程序不运行，但它不会给我错误

我是springmvc的初学者，我用maven在eclipse中创建了一个webapp项目，并用java纯代码进行了配置。在项目中没有错误，但当我运行它时，它不工作，它给我HTTP404错误[/springcalculator/test]不可用。springcalculator是我的名字，project test是controller urlMap
类calculatorapplicationinitializer，用于替换xml配置中的web.xml

public class CalculatorApplicationInitializer implements WebApplicationInitializer {

             public void onStartup(ServletContext servletContext) throws ServletException {

            AnnotationConfigWebApplicationContext  WebApplicationContext = new   
            AnnotationConfigWebApplicationContext();
            WebApplicationContext.register(CalculatorAppContext.class);

            // create servlet Dispacher object
            DispatcherServlet dispatcherServlet = new
            DispatcherServlet(WebApplicationContext);  

            //registred dispatcher servlet with servlet context
            ServletRegistration.Dynamic myCustomDispatcherServlet =           
            servletContext.addServlet("MyDispatcherServlet",dispatcherServlet);

            myCustomDispatcherServlet.setLoadOnStartup(1);
            myCustomDispatcherServlet.addMapping("/");

        }

    }

在xml配置中替换applicationcontext.xml的类calculatorappcontext

@EnableWebMvc
    @Configuration

    @ComponentScan(basePackages = "com.home.lc.controllers")
    public class CalculatorAppContext {

        // setup my view resolver
        @Bean
        public InternalResourceViewResolver viewResolver() {

        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/view/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }
    }

That's the controller returning vue

    @Controller
    public class TestController {

    @RequestMapping("/test")
     public String SayHello() {

         return "hi" ;
     }
    }

vue高.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
        pageEncoding="UTF-8"%>
    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="UTF-8">
    <title>:)</title>
    </head>
    <body>
    <p> Hello </p>

    </body>
    </html>
