私はフィールドを持っています: Ordinality DB: ORDINALITY NOT NULL NUMBER(2) 

@Column(name="ORDINALITY")
@NotNull(message="Ordinality is Mandatory")
@Size(max=2,message="Ordinality exceeded the limit, Max. 2 numbers are allowed.")
private BigDecimal ordinality;
  1. 入力を数字のみに制限したいのですが、正確な注釈構文はどうなりますか。
  2. 適切な値を指定しているときと、値を指定していないときにページを送信すると、エラーが発生します。
javax.validation.UnexpectedTypeException: HV000030: No validator could be found for type: java.math.BigDecimal.

To set precision of the underlying database field, you should use the precision and the scale elements of the @Column annotation.

@Column(precision=10, scale=2)

To validate the number use the @DecimalMax annotation.

@DecimalMax("30.00")
