这是主控制器类。登录后，我希望它重定向到LoggedIn.jsp页面，但我收到404错误。请帮忙。
我仍然没有提供任何登录验证代码。我只想看看重定向是如何工作的。我是初学MVC及其概念的新手。请为我提供相同的建议和解决方案。
所有代码文件如下：
package com.example.myproject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
//import org.springframework.web.bind.annotation.RequestParam;
@Controller
public class HelloController {
@RequestMapping(value="/HelloPage" , method=RequestMethod.GET)
public String showLoginForm()
{
return "HelloPage";
}
@RequestMapping(value="/redirect" , method=RequestMethod.GET)
public String redirectPage()
{
return "redirect:LoggedIn";
}
@RequestMapping(value="/LoggedIn" , method =RequestMethod.GET)
public String redirectLoggedIn()
{
return "LoggedIn";
}
}
