我得到這個異常：java.lang.IllegalStateException：無論BindingResult也不是爲bean名稱 'RegistrationBean' 可以作爲請求屬性平原目標對象
java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'RegistrationBean' available as request attribute
這是我的控制器類
@Controller
public class TenantRegistrationController {
@Autowired
private TenantService tenantService;
@Autowired
private UserService userService;
RegistrationBean是從jsp作爲模型屬性傳遞的bean類。
@RequestMapping(value="/registration", method= RequestMethod.POST)
public String addNewTenant(@ModelAttribute("RegistrationBean")RegistrationBean registrationBean,
BindingResult result, Map<String,Object> map)
{
Tenant tenant = new Tenant();
tenant.setTenant_name(registrationBean.getTenantName());
tenant.setTenant_email(registrationBean.getTenantEmail());
tenant.setAddress(registrationBean.getTenantAddress());
// tenant.setReminder_email(Integer.parseInt(registrationBean.getReminderMail()));
tenant.setReminder_email(registrationBean.getReminderMail());
tenant.setThankyou_email(registrationBean.getThankyouMail());
CurrencyFormat cf = new CurrencyFormat();
cf.setCurrencyFormatId(registrationBean.getCurrencyFormatId());
tenant.setTenantCurrencyFormat(cf);
DateFormat df = new DateFormat();
df.setDateFormatId(registrationBean.getDateFormatId());
tenant.setTenantDateFormat(df);
tenant.setRegistration_date(registrationBean.createRegistrationDate());
tenantService.addTenant(tenant);
User user = new User();
user.setName(registrationBean.getUserName());
user.setAddress(registrationBean.getUserAddress());
user.setUser_name(registrationBean.getUserLoginName());
user.setDesignation(registrationBean.getUserDesignation());
user.setPassword(registrationBean.getUserPassword());
user.setEmail(registrationBean.getUserEmail());
user.setContact_number(registrationBean.getUserContactNo());
Role urole=new Role();
urole.setRole_id(1);
user.setUser_role(urole);
userService.addUser(user);
map.put("tenant_name", tenant.getTenant_name());
return "tenant_registration_success";
}
@RequestMapping("/addANewTenant")
public String showAddTenantPage(Map<String, Object> map)
{
/*map.put("item", new Item());
map.put("itemList", itemService.listitems());*/
return "add_tenant_details";
}
}
這是我的JSP文件
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Tanent Registration and Tanent Administrator Registration</title>
<style>
.error {
color: #ff0000;
font-style: italic;
}
</style>
</head>
<body>
