使用自定義註釋進行彈簧窗體驗證

我在基於spring4.2.3和hibernate5.1.0的項目中使用自定義註釋進行表單驗證。使用自定義註釋進行彈簧窗體驗證

1）我的註釋界面看起來像這樣

import java.lang.annotation.Documented; 
import java.lang.annotation.ElementType; 
import java.lang.annotation.Retention; 
import java.lang.annotation.RetentionPolicy; 
import java.lang.annotation.Target; 
import javax.validation.Constraint; 
import javax.validation.Payload; 
import com.rapidtech.rapidtechorganic.custom.logic.UnitConstraintValidator; 
@Documented 
@Constraint(validatedBy = UnitConstraintValidator.class) 
@Target({ElementType.FIELD}) 
@Retention(RetentionPolicy.RUNTIME) 
public @interface IsUnit { 

String message() default "Please Enter a valid UNIT e.g. kg,litre,ton"; 

Class<?>[] groups() default {}; 

Class<? extends Payload>[] payload() default {}; 

}

2）我的邏輯類UnitConstraintValidator看起來像這樣

import javax.validation.ConstraintValidator; 
import javax.validation.ConstraintValidatorContext; 
import com.rapidtech.rapidtechorganic.custom.annotation.IsUnit; 

public class UnitConstraintValidator implements ConstraintValidator<IsUnit, String> { 

@Override 
public void initialize(IsUnit unit) { 
    // TODO Auto-generated method stub 

} 

@Override 
public boolean isValid(String unit, ConstraintValidatorContext cxt) { 

    if(unit.equals(null) || unit == null){ 
     return false; 
    } 

    if(unit.matches("kg|KG|Kg|Litre|litre|lt|ton|Ton")){ 

     return true; 

    } 

    return false; 
} 

}

3）我的模型類，其中我使用自定義註解

import javax.persistence.CascadeType; 
import javax.persistence.Entity; 
import javax.persistence.GeneratedValue; 
import javax.persistence.GenerationType; 
import javax.persistence.Id; 
import javax.persistence.OneToOne; 
import javax.validation.constraints.Size; 
import com.fasterxml.jackson.annotation.JsonIgnoreProperties; 
import com.rapidtech.rapidtechorganic.custom.annotation.IsUnit; 
@JsonIgnoreProperties(ignoreUnknown = true) 
@Entity 
public class Lot implements java.io.Serializable{ 

/** 
* 
*/ 
private static final long serialVersionUID = 1L; 

@Id 
@GeneratedValue(strategy=GenerationType.AUTO) 
private long lotId; 

@Size(min=5,max=30) 
private String lotNumber; 

@IsUnit 
private String lotName; 

@OneToOne(cascade = {CascadeType.ALL}) 
private ProductAvailable productAvailable; 

public long getLotId() { 
    return lotId; 
} 
public void setLotId(long lotId) { 
    this.lotId = lotId; 
} 
public String getLotNumber() { 
    return lotNumber; 
} 
public void setLotNumber(String lotNumber) { 
    this.lotNumber = lotNumber; 
} 
public String getLotName() { 
    return lotName; 
} 
public void setLotName(String lotName) { 
    this.lotName = lotName; 
} 
public ProductAvailable getProductAvailable() { 
    return productAvailable; 
} 
public void setProductAvailable(ProductAvailable productAvailable) { 
    this.productAvailable = productAvailable; 
} 



}

4）我的ProductAvailable模型類，我使用的是自定義註釋

import javax.persistence.Entity; 
import javax.persistence.GeneratedValue; 
import javax.persistence.GenerationType; 
import javax.persistence.Id; 
import javax.persistence.OneToOne; 
import javax.validation.constraints.Size; 
import com.rapidtech.rapidtechorganic.custom.annotation.IsUnit; 

@Entity 
public class ProductAvailable implements java.io.Serializable { 
/** 
* 
*/ 
private static final long serialVersionUID = 1L; 

@Id 
@GeneratedValue(strategy=GenerationType.AUTO) 
private long productAvailableId; 

@Size(min=2,max=30,message="ahha ahha ahha") 
private String productAvailableName; 

@IsUnit 
private String productAvailableUnit; 
private double productAvailableUnitTransportationCharge; 
private double productAvailableUnitLabourCharge; 
private double productAvailableUnitOtherCharge; 
private long productAvailableQuantity; 
private double productAvailableUnitPrice; 

@OneToOne 
private Lot lot; 


public long getProductAvailableId() { 
    return productAvailableId; 
} 
public void setProductAvailableId(long productAvailableId) { 
    this.productAvailableId = productAvailableId; 
} 
public String getProductAvailableName() { 
    return productAvailableName; 
} 
public void setProductAvailableName(String productAvailableName) { 
    this.productAvailableName = productAvailableName; 
} 
public long getProductAvailableQuantity() { 
    return productAvailableQuantity; 
} 
public void setProductAvailableQuantity(long productAvailableQuantity) { 
    this.productAvailableQuantity = productAvailableQuantity; 
} 
public double getProductAvailableUnitPrice() { 
    return productAvailableUnitPrice; 
} 
public void setProductAvailableUnitPrice(double productAvailableUnitPrice) { 
    this.productAvailableUnitPrice = productAvailableUnitPrice; 
} 

public String getProductAvailableUnit() { 
    return productAvailableUnit; 
} 
public void setProductAvailableUnit(String productAvailableUnit) { 
    this.productAvailableUnit = productAvailableUnit; 
} 
public double getProductAvailableUnitTransportationCharge() { 
    return productAvailableUnitTransportationCharge; 
} 
public void setProductAvailableUnitTransportationCharge(double productAvailableUnitTransportationCharge) { 
    this.productAvailableUnitTransportationCharge = productAvailableUnitTransportationCharge; 
} 
public double getProductAvailableUnitLabourCharge() { 
    return productAvailableUnitLabourCharge; 
} 
public void setProductAvailableUnitLabourCharge(double productAvailableUnitLabourCharge) { 
    this.productAvailableUnitLabourCharge = productAvailableUnitLabourCharge; 
} 
public double getProductAvailableUnitOtherCharge() { 
    return productAvailableUnitOtherCharge; 
} 
public void setProductAvailableUnitOtherCharge(double productAvailableUnitOtherCharge) { 
    this.productAvailableUnitOtherCharge = productAvailableUnitOtherCharge; 
} 
public Lot getLot() { 
    return lot; 
} 
public void setLot(Lot lot) { 
    this.lot = lot; 
} 




}

我使用hibernate-validator4.1.0.Final和JSR 303進行驗證。

正如您所看到的，我有兩個模型類Lot和ProductAvailable，映射OneToMany意味着一個Lot可以有多個ProductAvailable。

我的問題是：我的自定義annotaion IsUnit做工精細用類地塊但類ProductAvailable的情況下拋出異常。

的例外是：

javax.validation.ConstraintViolationException: Validation failed for classes [com.rapidtech.rapidtechorganic.model.ProductAvailable] during persist time for groups [javax.validation.groups.Default, ] 
List of constraint violations:[ 
ConstraintViolationImpl{interpolatedMessage='Please Enter a valid UNIT e.g. kg,litre,ton', propertyPath=productAvailableUnit, rootBeanClass=class com.rapidtech.rapidtechorganic.model.ProductAvailable, messageTemplate='Please Enter a valid UNIT e.g. kg,litre,ton'}

我的控制器類看起來是這樣的：

@RequestMapping(value = "/saveLot", method = RequestMethod.POST) 
public ModelAndView saveLotController(@Valid @ModelAttribute(value="lot") Lot lot, BindingResult result) { 
    ModelAndView model; 

    if(result.hasErrors()){ 
     model = new ModelAndView("saveLotForm"); 
    } 
    else { 
    Services lotService = (LotServiceImpl) appContext.getBean("lotServiceImpl"); 
    lot.getProductAvailable().setLot(lot); 
    lotService.save(lot); 
    model = new ModelAndView("Success"); 
    model.addObject("successMessage","Lot "+lot.getLotName()+" Saved Successfully!"); 
    } 
    return model; 
}

任何幫助將appreaciated並在此先感謝。

問題在於?!它驗證並且不符合驗證規則。所以是的，它會失敗。 –

你能告訴我究竟在哪裏？ – tinku

在做一些研究之後，我找到了解決辦法。所有我需要把@Valid標註了類地塊

我productAvailable成員變量，它會檢查驗證了我的ProductAvailable類。
