嗨,我很难使用以下网址:
<a href="/noticeOpen/2">dynamicLink</a>
使用以下控制器方法进行映射:
@RequestMapping(value="/noticeOpen/{quesId}")
public ModelAndView noticeOpen(@ModelAttribute("NoticeForm") NoticeForm noticeForm,
ModelMap model,
@PathVariable("quesId") Integer quesId){
System.out.println(quesId);
return new ModelAndView("/noticeOpen","noticeForm",noticeForm);
}
当我单击锚点dynamicLink时问题开始,它不会将控制权转移到我的控制器,而是在浏览器的地址栏中显示以下内容:
http://127.0.0.1:8080/prj/noticeOpen/2/WEB-INF/pages/noticeOpen.jsp
此外,我在 applicationContext.xml 中有以下映射
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">
<value>WEB-INF/pages/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
如果我从控制器的 @RequestMapping 中删除 {quesId} 并从方法签名中删除 @PathParam ,这一切都很好(也从 anchor 中删除 questionId )
http://127.0.0.1:8080/prj/noticeOpen
但这听起来并不动态并满足我的要求。

更新
我为它创建了新的控制器,/noticeOpen/{quesId}
现在它获得了控制权,但我无法理解以下方法的行为。请在 NoticeController 上查看下面的内容,然后得出以下结果:
@Controller
public class NoticeController {
@RequestMapping(value="/noticeOpen/{quesId}")
public ModelAndView noticeOpen(@ModelAttribute("NoticeForm") NoticeForm noticeForm,ModelMap model,@PathVariable("quesId") Integer quesId){
return new ModelAndView("noticeOpen","noticeForm",noticeForm);
}
@RequestMapping(value="/noticeOpen")
public ModelAndView noticeOpen(@ModelAttribute("NoticeForm") NoticeForm noticeForm,ModelMap model){
return new ModelAndView("noticeOpen","noticeForm",noticeForm);
}
@RequestMapping(value="/noticeOpen")
它将我重定向到正确的 noticeOpen.jsp
@RequestMapping(value="/noticeOpen/{quesId}")
它将我重定向到以下错误页面
