spring mvc annotation jsp page loading error

Question

我只能切换到我创建的一个jsp页面。当我想上传其他人时，我无法访问该页面。

包com.ugur.controller如下;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class ugur {

    @RequestMapping("/javapage")
    public ModelAndView  javapage() {
        ModelAndView model_java = new ModelAndView("javapage");
        return model_java;
    }

    @RequestMapping("/stm")
    public ModelAndView  stm() {
        ModelAndView model_stm = new ModelAndView("stm");
        return model_stm;
    }
}

index.jsp页面的一部分;

    <li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">Projects <b class="caret"></b></a>
    <ul class="dropdown-menu">
    <li><a href="${contextPath}/javapage">JAVA</a></li>
    <li><a href="${contextPath}/stm">STM32</a></li>
