스프링 3 타입 변환 에러

Question

새로운 스프링 MVC 3.0 타입 변환 프레임 워크를 사용해 보았습니다. 변환 오류를 잡는 방법을 찾을 수 없습니다.

    <!-- Scan this package and sub-packages for Annotated Controllers --> 
    <context:component-scan base-package="springmvc.simple"/>    

    <!-- New Spring 3.0 tag to enable new Converter and Formatting Frameworks -->    
    <mvc:annotation-driven/> 

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
     <property name="prefix" value="/WEB-INF/views/" /> 
     <property name="suffix" value=".jsp" /> 
    </bean> 

    </beans> 

그리고 간단한 명령 클래스 :

public class Amount { 

@NumberFormat(style=Style.CURRENCY) 
@Min(0) 
private BigDecimal amount = BigDecimal.valueOf(10000, 2); 

@DateTimeFormat(iso=ISO.DATE) 
private Date date = new Date(); 

public Date getDate() { 
    return date; 
} 

public BigDecimal getAmount() { 
    return amount; 
} 

} 

그리고 똑같이 간단한 컨트롤러 : 나는 새로운 MVC 스키마를 사용하고

는

@Controller 
@RequestMapping(value="/addVat.html") 
public class AddVatController { 

@InitBinder 
public void initBinder(WebDataBinder binder) { 
    binder.initDirectFieldAccess(); 
    } 

@RequestMapping(method = RequestMethod.GET) 
public String setupForm(Model model) { 
    model.addAttribute("commandBean", new Amount()); 
    return "addVatForm"; 
} 

@RequestMapping(method = RequestMethod.POST) 
public String onSubmit(@ModelAttribute("commandBean") @Valid Amount commandBean, BindingResult amountBinding, Model model) { 

    if (amountBinding.hasErrors()) { 
    return "addVatForm"; 
    } 

    BigDecimal result = commandBean.getAmount().multiply(new BigDecimal("1.175")); 
    model.addAttribute("result", result); 

    return "result"; 
} 
} 

이 잘 작동 - I BigDecimal에 음수 값을 입력하면 my result.jsp에 유효성 검사 오류가 발생합니다. - 나는 ####을 준수하지 않는 날짜와 같은 2010-07-024, 보내려고하지만 경우 ####을, 나는 오류 얻을 : 괜찮

을 -하지만 어떻게 오류를 잡아낼 수 있습니까? BindingResult에 단순히 다른 오류가 포함될 것으로 예상 했습니까? 유르겐 Hoeller에 따르면

Answer 1

,이 봄 확실히 오류가 멀리 갈 수 3.0.2

Answer 2

적절한 DateEditor을 등록하는 것은 당신을 도울 수 있는지 확인

..... 15.3.2.12

@InitBinder 
    public void initBinder(WebDataBinder binder) { 
     binder.initDirectFieldAccess(); 
     **/* register appropriate date editor */** 
     SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd"); 
     dateFormat.setLenient(false); 
     binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, false)); 
    }
