Java POJOs (Plain Old Java Objects) are the standard way to represent JSON data in Spring Boot and other Java frameworks. The Jackson library uses @JsonProperty annotations to map between JSON field names and Java field names. This generator creates complete classes with private fields, public getters and setters, following Java naming conventions.
