獲得從JSP到控制器的日期（在Spring MVC）

Question

我woulde想從我的JSP得到日期到我的控制器，但我嘗試了所有，但我還沒有得到一個結果：

JSP

<div> 
    <f:form modelAttribute="banqueForm2" method="post" action="testero33"> 
     <table> 
      <tr> 
       <td>Date1 :</td> 
       <td><f:input path="date1" type="date" name="date" /> 
       </td> 
       <td><f:errors path="date1" cssClass="error"> 
        </f:errors></td> 

        <td>Date2 :</td> 
       <td><f:input path="date2" type="date" name="date" /> 
       </td> 
       <td><f:errors path="date2" cssClass="error"> 
        </f:errors></td> 

       <td><input type="submit" value="OK" /></td> 
      </tr> 
     </table> 
    </f:form> 
</div> 

控制器

@RequestMapping(value="/testero33") 
public String testero3(@Valid BanqueForm2 bf, Model model, Date date1, Date date2){ 
    System.out.println("-------------date JSP---------------: "); 
    System.out.println("*** Cosluter Strin ***: " + date1); 
    System.out.println("*** Cosluter Strin ***: " + date2); 

    System.out.println("------------End JSP---------------: "); 

    return "DateTest"; 
} 

個BanqueForm2.class

public class BanqueForm2 { 

    private Date date1; 
    private Date date2; 


    public Date getDate1() { 
     return date1; 
    } 
    public void setDate1(Date date1) { 
     this.date1 = date1; 
    } 
    public Date getDate2() { 
     return date2; 
    } 
    public void setDate2(Date date2) { 
     this.date2 = date2; 
    } 
} 

然後我得到這個例外

Field error in object 'banqueForm2' on field 'date1': rejected value [2015-10-01]; codes [typeMismatch.banqueForm2.date1,typeMismatch.date1,typeMismatch.java.util.Date,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [banqueForm2.date1,date1]; arguments []; default message [date1]]; default message [Failed to convert property value of type 'java.lang.String' to required type 'java.util.Date' for property 'date1'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type java.lang.String to type java.util.Date for value '2015-10-01'; nested exception is java.lang.IllegalArgumentException] 
Field error in object 'banqueForm2' on field 'date2': rejected value [2015-02-12]; codes [typeMismatch.banqueForm2.date2,typeMismatch.date2,typeMismatch.java.util.Date,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [banqueForm2.date2,date2]; arguments []; default message [date2]]; default message [Failed to convert property value of type 'java.lang.String' to required type 'java.util.Date' for property 'date2'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type java.lang.String to type java.util.Date for value '2015-02-12'; nested exception is java.lang.IllegalArgumentException]org.springframework.web.method.annotation.ModelAttributeMethodProcessor.resolveArgument(ModelAttributeMethodProcessor.java:111)

我認爲你需要一個日期約束力。

嘗試把這個在你的控制器

@InitBinder 
public final void initBinderUsuariosFormValidator(final WebDataBinder binder, final Locale locale) { 
    final SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd", locale); 
    binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));  
} 

這樣春天就會知道如何將一個字符串轉換成日期（記住，Request對象就是一個String地圖）
