Hibernate的驗證錯誤

Question

經與Hibernate驗證

收到此錯誤

java.lang.IllegalStateException大問題：無論是BindingResult也不是爲bean名稱「公司」可作爲請求屬性平原目標對象

這裏是我的控制器

import java.util.logging.Logger; 

import javax.validation.Valid; 

import org.springframework.stereotype.Controller; 
import org.springframework.ui.ModelMap; 
import org.springframework.validation.BindingResult; 
import org.springframework.web.bind.annotation.ModelAttribute; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 
import org.springframework.web.bind.annotation.SessionAttributes; 

import com.muuves.reservosity.model.Business_Register; 

@Controller 
@SessionAttributes({"company"}) 
@RequestMapping("/business") 
public class BusinessController { 
private final static Logger LOG = Logger.getLogger(BusinessController.class .getName()); 


@RequestMapping(method = RequestMethod.GET) 
public String business(ModelMap model) { 
    LOG.info("Entering Business Home"); 
    model.put("company", new Business_Register()); 
    return "business"; 
} 
@RequestMapping(value="/register", method = RequestMethod.GET) 
public String businessRegister() { 
    LOG.info("Register Business Page"); 
    return "business_register"; 
} 

@RequestMapping(value = "/add", method = RequestMethod.POST) 
public String addBusiness(@Valid Business_Register company, BindingResult result, ModelMap model) { 
    LOG.info("Registering Business"+result.getErrorCount()); 
    if (result.hasErrors()){ 
     System.out.println("I found errors now now"); 
     return "business_register"; 
    } 
    //companyService.addCompany(company); 
    return "business_add"; 
} 

}

這是JSP

<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%> 

<div class="row main-content-reservosity"> 
<div class="twelve columns"> 
    <h3>Register Your Business</h3>

我有這個進口到我的pom.xml

  <dependency> 
     <groupId>org.hibernate</groupId> 
     <artifactId>hibernate-validator</artifactId> 
     <version>4.3.1.Final</version> 
    </dependency>

需要添加@ModelAttribute（ 「公司」）http://blog.nigelsim.org/2011/09/07/spring-mvc-validation-bindingresult/

而且它的工作原理

看起來很荒謬，你需要做這個thoug h
