嗨,我很难跟进网址:
<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);
}
当我点击锚 dynamicLink 并且它没有将控制权转移到我的控制器时问题就开始了,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>
如果我从方法签名中删除控制器的@RequestMapping和@PathParam中的{quesId}(也从锚中删除questionId),这一切都可以正常工作
http://127.0.0.1:8080/prj/noticeOpen
但这听起来不是动态的,符合我的要求。
的web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

更新
我为/noticeOpen/{quesId}
创建了新的Controller,它现在获得了控件,但我无法理解以下方法的行为。
请看下面的NoticeController,然后在下面得到结果:
@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}")
它会将我重定向到以下错误页面
HTTP Status 404 - /prj/noticeOpen/WEB-INF/pages/noticeOpen.jsp
type Status report
message /prj/noticeOpen/WEB-INF/pages/noticeOpen.jsp
description The requested resource is not available.
Apache Tomcat/6.0.36
答案 0 :(得分:3)
在applicationContext.xml中更改前缀值,如下所示
<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>
WEB-INF之前的斜线。它会起作用。
