java - Spring MVC、Maven、Pivo​​tal tc 服务器 HTML 404 未找到错误

Question

按照 spring mvc 教程，我得到了错误

HTTP 状态 [404] – [未找到]源服务器未找到目标资源的当前表示，或者不愿透露存在的表示。

任何人都可以找出缺少的内容或可以指出正确的方向吗？

使用spring tools suit 3.9.o和pivotal tc server和maven

HomeController.java

    package com.infiniteskills.mvc;

     import java.text.DateFormat;
     import java.util.Date;
     import java.util.Locale;

     import org.slf4j.Logger;
     import org.slf4j.LoggerFactory;
     import org.springframework.stereotype.Controller;
     import org.springframework.ui.Model;
     import org.springframework.web.bind.annotation.RequestMapping;
     import org.springframework.web.bind.annotation.RequestMethod;

     /**
      * Handles requests for the application home page.
      */
      @Controller
      public class HomeController {

        private static final Logger logger = 
        LoggerFactory.getLogger(HomeController.class);

        /**
         * Simply selects the home view to render by returning its name.
         */
        @RequestMapping(value = "/", method = RequestMethod.GET)
        public String home(Locale locale, Model model) {
            logger.info("Welcome home! The client locale is {}.", locale);

            Date date = new Date();
            DateFormat dateFormat = 
     DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG,locale);

            String formattedDate = dateFormat.format(date);

        model.addAttribute("serverTime", formattedDate );

            return "home";
        }

          }

Answer 1

你需要在@Controller之后使用@RequestMapping("/homeController")来映射Controller。并在方法之前使用 @RequestMapping(value = "/hello", method = RequestMethod.GET)。和 url 将 b : http://localhost:8080/project-name/homeController/hello 并使用 GET 方法。
