Grails拒绝值，类型不匹配,grails,grails-2.0,grails-domain-class,grails-controller,Grails,Grails 2.0,Grails Domain Class,Grails Controller,我不知道我的代码出了什么问题，值是正确的，但当我保存它时，它会出错 grails.validation.ValidationException: Validation Error(s) occured during save(): - Field error in object 'specialRate' on field 'fromCurrency': rejected value [IDR - Indonesian Rupiah]; codes [typeMismatch.specialRa

我不知道我的代码出了什么问题，值是正确的，但当我保存它时，它会出错

grails.validation.ValidationException: Validation Error(s) occured during save():
- Field error in object 'specialRate' on field 'fromCurrency': rejected value [IDR - Indonesian Rupiah]; codes [typeMismatch.specialRate.fromCurrency, ......

grails.validation.ValidationException: Validation Error(s) occured during save():
- Field error in object 'specialRate' on field 'validThru': rejected value [Mon JUl 15 00:00:00 ICT 2013]; codes [typeMismatch.specialRate.fromCurrency, ...... could not parse date: Unparsable date: "15/07/2013"]

这是我的域名类

import java.util.Date;
import Currency;

    class SpecialRate {

        static auditable = true

            String bookingCode
        Currency fromCurrency
        Date validThru

        static constraints = {
        bookingCode(blank: false, maxSize :20)
            fromCurrency(blank:true, nullable: true)
            validThru(blank: true, nullable: true)      
        }
    }

下面是保存控制器：

def save = {    
        def specialRateInstance = new SpecialRate()
        specialRateInstance.properties = params
        SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy")
        specialRateInstance.validThru = formatter.parse(params.validThru)

        def fromCurrency = Currency.get(params.fromCurrency);
        specialRateInstance.fromCurrency = fromCurrency


        withFormat {
            html {
                withForm {
                    try {
                        specialRateInstance = specialRateService.save(specialRateInstance)
                    }
                    catch (grails.validation.ValidationException e) {
                        logger.error("Missing property or validation fails", e)
                    }
                    catch (RuntimeException e) {
                        logger.error(e.getMessage(), e)
                        redirect(controller: "error", action: "serverError")
                        return
                    }

                    if (!specialRateInstance.hasErrors()) {
                        flash.message = "${message(code: 'default.created.message', args: [message(code: 'specialRate.label', default: 'SpecialRate'), specialRateInstance.bookingCode])}"
                        redirect(action: "show", id: specialRateInstance.id)
                    }
                    else {
                        render(view: "create", model: [specialRateInstance: specialRateInstance ])
                    }
                }.invalidToken {
                    redirect(controller: "error", action: "forbidden")
                }
            }
        }
    }

以及服务：

def save (def specialRateInstance){
        specialRateInstance.save(failOnError: true)
        return specialRateInstance
    }

任何人都可以帮我找到我的错误，这样我的代码就能得到错误结果吗？谢谢：）

```
fromCurrency
```
的类型为
```
Currency
```
，但您需要从
```
params
```
设置字符串值
```
validThru
```
是不可解析的，因为格式是
```
Mon JUl 15 00:00:00 ICT 2013
```
，您希望它是
```
dd/MM/yyyy
```

恢复的步骤：

跟随@jameskleeh
一旦设置，验证
```
from Currency
```
是否为
```
Currency
```
类型
匹配
```
validThru
```
的日期格式。确保
```
validThru
```
在
```
params
```
中设置为
```
dd/MM/yyyy
```

您是否尝试过：

def specialRateInstance=new SpecialRate（params）
