Bean Validation Cheat Sheet — Combining Constraints
Validation annotations can be combined in any suitable way. For instance, to specify a valid reviewRating value between 1 and 5, specify the validation like this @Min(value=), @Max(value=) BigDecimal, BigInteger, byte, short, int, long and the respective wrappers of the primitive types; Additionally

BigDecimal, BigInteger, byte, short, int, long and the respective wrappers of the primitive types; Additionally supported by HV: any sub-type of CharSequence (the numeric value represented by the character sequence is evaluated), any sub-type of Number
Checks whether the annotated value is higher/lower than or equal to the specified minimum

@Min(1)

private int reviewRating;
public int getReviewRating() {
return reviewRating;
}
public void setReviewRating(int reviewRating) {
this.reviewRating = reviewRating;
