Bean驗證範圍制約

Question

我需要實現實體數據字段範圍約束：

@Entity 
@Table(name = "T_PAYMENT") 
public class Payment extends AbstractEntity { 

    //.... 

    //Something like that 
    @Range(minValue = 80, maxValue = 85) 
    private Long paymentType; 

} 

我已經創建的驗證服務，但要實現許多這些情況。

如果插入的數字超出範圍，我需要應用程序拋出異常。

Answer 1

你需要hibernate-validator

Please refer to this official documentation.

註釋

@Range(min=, max=) 

支持的數據類型

BigDecimal, BigInteger, CharSequence, byte, short, int, long and the respective wrappers of the primitive types 

使用

Checks whether the annotated value lies between (inclusive) the specified minimum and maximum 

Answer 2

隨着hibernate-validator依賴可以定義範圍檢查

@Min(value = 80) 
@Max(value = 85) 
private Long paymentType; 

在pom.xml添加下面的依賴

<dependency> 
     <groupId>org.hibernate</groupId> 
     <artifactId>hibernate-validator</artifactId> 
     <version>{hibernate.version}</version> 
    </dependency>
