object-validator

Simple Object Validator based on Hibernate validation library

Rules can be build by code or in the JSON format

• KeyObject is any object you want to use as a key for your validation rules
• classes is a classes you want to validate
• fields is a fields you want to validate
• constraints is validation rules

val key = KeyObject(officeId = 57, anotherField = "value")
val rule = DefaultConstraintMapping()
rule.type(TestDTO::class.java)
   .property("id", ElementType.FIELD)
   .constraint(NotEmptyDef().message("errorMessage"))
   .constraint(PatternDef().message("errorMessage").regexp("\\b[A-Z0-9._%-]+@[A-Z0-9.-]+\\.[A-Z]{2,4}\\b"))

validatorFactory.add(key, rule)
validatorFactory.validate(key, TestDTO("non valid"))

Representation of a file with rules for validation:

{
  "key": {
    "officeId": 57,
    "anotherField": "value"
  },
  "classes": [
    {
      "name": "com.isadounikau.TestDTO",
      "fields": [
