Jakarta Validation

EasyYapi supports Jakarta Validation annotations for marking fields and parameters as required.

Extension Config

# Jakarta Validation support (enabled by default when jakarta.validation.constraints.NotNull is on classpath)
param.required=@jakarta.validation.constraints.NotBlank
field.required=@jakarta.validation.constraints.NotBlank
param.required=@jakarta.validation.constraints.NotNull
field.required=@jakarta.validation.constraints.NotNull
param.required=@jakarta.validation.constraints.NotEmpty
field.required=@jakarta.validation.constraints.NotEmpty

Supported Annotations

Annotation	Rule	Description
@NotBlank	param.required / field.required	Mark as required
@NotNull	param.required / field.required	Mark as required
@NotEmpty	param.required / field.required	Mark as required

Jakarta Validation Strict

There is also a strict mode (jakarta-validation-strict extension) that respects validation groups. When using @Validated with specific groups, only constraints matching those groups will be applied.

This extension is disabled by default. Enable it in IDE settings if you need group-based validation.

Example

public class CreateUserRequest {
    @NotNull
    private String name;

    @Email
    @NotBlank
    private String email;

    @NotEmpty
    private List<String> roles;
}

All three fields will be marked as required in the API documentation.
