How do I generate POJOs for Spring Boot applications?

Our converter creates Spring Boot-compatible POJOs with Jackson annotations for JSON serialization. Enable @JsonProperty annotations, set your package name (e.g., com.yourapp.model), and the generated classes will work seamlessly with Spring Boot REST controllers and JPA repositories.

Should I use Lombok annotations or traditional getters/setters?

Lombok annotations (@Data, @Builder) reduce boilerplate code significantly and are recommended for modern Java projects. However, if your team doesn't use Lombok or has specific requirements, traditional getters/setters provide full control and compatibility with all Java environments.

Can the generated POJOs handle nested JSON objects?

Yes, our converter automatically handles nested JSON objects by creating appropriate field types and can generate nested classes when needed. Complex JSON structures are properly mapped to Java object hierarchies with correct type relationships.

How do I handle JSON arrays and collections in POJOs?

JSON arrays are automatically converted to Java List types with proper generic typing. The converter analyzes array elements to determine the appropriate generic type, ensuring type-safe collection handling in your Java code.
