Package me.josephsf.jobportaljosephsfeir.dto

package me.josephsf.jobportaljosephsfeir.dto

Provides Data Transfer Objects (DTOs) for the Job Portal application.

This package contains all the Data Transfer Objects used throughout the Job Portal system to transfer data between different layers of the application (controller, service, repository) and between the server and client. DTOs are immutable objects that only contain fields, getters/setters, and validation constraints.

The DTO classes in this package serve several purposes:

• Decoupling the domain model from the presentation layer
• Handling input validation through Jakarta Bean Validation annotations
• Providing clear API contracts for data exchange
• Hiding implementation details of the domain model

Key DTOs include:

• CandidateDto - For job seeker profile data
• RecruiterDto - For company recruiter profile data
• JobDto - For job listing information
• ApplicationDto - For job application data
• LoginDto - For authentication credentials
• RegisterDto - For user registration data
• JwtResponseDto - For authentication token responses
• ApiResponseDto - For standardized API responses
• UserDto - For user account information

Most DTOs contain validation annotations from the Jakarta Bean Validation API to ensure data integrity before processing requests:

• @NotNull - Ensures a value is not null
• @NotBlank - Ensures a string value is not null, empty, or just whitespace
• @Size - Constrains the size of strings, collections, maps, and arrays
• @Min/@Max - Constrains numeric values
• @Email - Validates email format

Note that DTOs are distinct from domain model entities in the me.josephsf.jobportaljosephsfeir.model package, which represent the database entities. Conversion between DTOs and model entities is typically handled in the service layer.
