Question

我遇到了问题。这是我第一次这样做。我在JSP中使用Spring Rest Controller和Display生成了一个随机数程序。

现在我尝试的是我映射HTML文件，显示我在JSP中获得的内容。但我面对这个错误

找不到带URI的HTTP请求的映射

我尝试了各种网站，但没有理解那里的错误

这里我有HTML的高清图，我每隔5秒刷新一次页面。所以，我从服务器获取y轴的值，时间绘制在x轴上。我也被困在HTML文件的Ajax调用中。我无法弄清楚如何从服务器和其他轴值中获取一个轴值。

我在这里粘贴代码---

我的控制器 -

package com.xyz.rest.temperature.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.lucid.rest.temperature.exception.InvalidRangeException;
import com.lucid.rest.temperature.exception.NegativeNumberException;
import com.lucid.rest.temperature.util.RandomNumberGenerator;

@RestController
public class ReadingController {

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String getReading() throws NegativeNumberException,
            InvalidRangeException {
        return new Integer(new RandomNumberGenerator().generateRandomNumber(
                100, 50)).toString();
        }

     @RequestMapping(value = "/staticPage", method = RequestMethod.GET)
       public String redirect() {

          return "redirect:/jsp/hello.htm";
       }
}

我的调度员Servlet -

所以我几乎粘贴了所有东西。请帮我弄清楚错误是什么，以及如何克服HTMl中的轴值问题

感谢任何帮助。如果您不明白，请发表评论。感谢
