我提示以下錯誤：收到錯誤 - java.lang.IllegalStateException：無論BindingResult也不是爲bean名稱「命令」可以作爲請求屬性在JSP頁面
我試圖搜索網，但普通的目標對象非解決方案正在解決這個問題。
請找我的控制器類
@Controller
public class LoginController {
@RequestMapping(value = "/login",method=RequestMethod.GET)
public String showLoginPage(Model model) {
model.addAttribute("login", new LoginBean());
return "login";
}
}
的login.jsp文件

pageEncoding="ISO-8859-1"%>

LoginBean.java類
public class LoginBean {
public LoginBean() {
}
private String emailId;
private String password;
public LoginBean(String emailId, String password) {
this.emailId = emailId;
this.password = password;
}
public String getEmailId() {
return emailId;
}
public void setEmailId(String emailId) {
this.emailId = emailId;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
