java - Optional multiple same constraints on field using Bean Validation -

i trying use hibernate validator validate pojo before insert database.

there field in bean either 8 or 10 in length.

i tried use built in constraint list put them together, expecting either 1 of criteria passes validation pass.

@length.list({@length(min=8, max=8,message="code either 8 or 10 characters in length"),@length(min=10, max=10,message="code either 8 or 10 characters in length")}) public string getcode() {     return this.code; } 

however, result shows criteria in list has passes make valid. know there anyway make or checking instead.

i think way annotation works this:

@length(min = 8, max = 10)   public string getcode() {    return code; } 

in other words 9 accepted valid, isn't you're looking for. i'm not sure if there's way 2 validations , or operation on them in hibernate annotations.

it looks can use @pattern validation this:

@pattern(regexp="(.{8}|.{10})", message="should either 8 or 10 characters") public string getcode() {    return code; }
