Validation of Pattern for Date Datatype is not working

[lovinjv]

We are migrating our spring boot application to java 17 . We are using jsonschema2pojo (v1.1.3) . We have a Date attribute with a pattern defined to validate (yyyy-mm-dd) values . The validation works fine in java 11 with javax.validation.constraints.Pattern, where the request is stopped with a Pattern check if the values does'not match .
But with java 17 and jakarta.validation.constraints.Pattern, the pattern check is not happening.

Sample json code:

{
  "updatedDate": {
    "type": "string",
    "format" : "date",
    "pattern": "^\\d{4}-\\d{2}-\\d{2}$"
  }
}

Note - It is a mandatory parameter.

Hi

I'd like to clarify

with java 17 and jakarta.validation.constraints.Pattern, the pattern check is not happening

Does that mean that POJOs are successfully generated and are annotated with jakarta.validation.constraints.Pattern ?

If yes, then I believe that there might be something missing/wrong with spring boot migration as jsonschema2pojo only deals with generation part and not with validation part.
It should be checked that appropriate validation factory (capable of handling/processing jakarta.validation.*) is being used

Agree with Unkish here. This library doesn't do validation - I'm unsure what framework, or libraries, or container you are deploying to, but whatever you are using for validation likely does not support those Jakarta validations.

It's possible we have something wrong in the way we are annotating, so do feel free to reopen if you find that is the case, but right now I think we are producing correct types but you should check whatever library you are using to validate.
