请找到以下代码:
viewResolver无法指向从控制器处理的所需视图。我在控制器中打印viewname。打印的viewname是正确的。但最后它会出现一个新的网址!!
请在下面找到详细信息!!
控制器
package in.co.linq.StudentAdmissionController;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.portlet.ModelAndView;
@Controller
public class StudentAdmissionController {
public StudentAdmissionController()
{
super();
System.out.println("StudentAdmissionController Constructor!!");
}
@RequestMapping(value="/Register" ,method=RequestMethod.GET)
public ModelAndView getRegisterForm()
{
ModelAndView modelAndView =new ModelAndView("Register");
modelAndView.addObject("msg","Register Me");
System.out.println("In getRegisterForm");
return modelAndView;
}
@RequestMapping(value="/HelloPage.html",method=RequestMethod.POST)
public ModelAndView submitRegisterForm(@RequestParam("txtname") String name,@RequestParam("txtcollege") String college
) {
ModelAndView modelAndView =new ModelAndView("HelloPage","msg", "Congrats!! Form submitted for "+name +" in college"+college);
//modelAndView.addObject("msg", "Congrats!! Form submitted for "+name +" in college"+college);
//modelAndView.addObject("college", college);
System.out.println(name+college);
System.out.println("In submitRegisterForm");
System.out.println(modelAndView.getViewName());
System.out.println(modelAndView.getModel());
return modelAndView;
}
@RequestMapping(value="/HelloPage/{countryName}/{userName}",method=RequestMethod.GET)
public ModelAndView method(@PathVariable("userName") String userName,@PathVariable("countryName") String countryName) {
ModelAndView modelAndView =new ModelAndView("HelloPage","msg", "Congrats!! Form submitted for "+userName+countryName);
//modelAndView.addObject("msg", "Congrats!! Form submitted for "+name +" in college"+college);
//modelAndView.addObject("college", college);
System.out.println(userName+countryName);
System.out.println("In submitRegisterForm");
System.out.println(modelAndView.getViewName());
System.out.println(modelAndView.getModel());
return modelAndView;
}
}
分派器-servlet.xml中
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
<property name="prefix">
<value>/WEB-INF/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
在网址上找到了错误 http://localhost:8080/SpringMVCUsingRequestParam/HelloPage.html/India/Nilotpal

控制台上的最后几行
INFO: Mapped URL path [/studentadmission/*] onto handler 'studentAdmissionController'
Jun 30, 2015 11:32:54 AM org.springframework.web.servlet.DispatcherServlet initServletBean

控制台
NilotpalIndia
In submitRegisterForm
HelloPage
{msg=Congrats!! Form submitted for NilotpalIndia}
这些线是控制器中打印的线。我可以看到视图是HelloPage
,但为什么它会将浏览器作为消息消息
/SpringMVCUsingRequestParam/WEB-INF/HelloPage.html/India/Nilotpal.jsp
做

尝试导入org.springframework.web.servlet.ModelAndView
而不是org.springframework.web.portlet.ModelAndView
ModelView类。
从Spring 3或更高版本的新版本开始,您可以直接返回视图名称作为方法返回值,如下所示
@RequestMapping("/HelloPage/{countryName}/{userName}",method=RequestMethod.GET)
public String helloSpring(Model model,@PathVariable("userName") String userName,@PathVariable("countryName") String countryName)
{
model.addAttribute("msg", "Congrats!! Form submitted for "+userName+countryName);
return "HelloPage";
}
您需要从方法参数中获取Model对象,可以将要传递给视图的值或对象添加到Model对象中,只返回方法中的视图名称。
我希望这对你有用。

你的网址有404错误
:/ SpringMVCUsingRequestParam/WEB-INF/HelloPage.html/India/Nilotpal.jsp
您的控制器被绑定到
:/ HelloPage / {countryName} / {userName}
如果您可以发布您的jsp或您重定向到该网址的按钮,但是 如果您从视图中删除.html,那么您可以使用该网址
