Here my application.properties:

springdoc.swagger-ui.default-model-expand-depth=99

My DO somehow something like this:

package com.hr_software_project.hr_management.entity;

import jakarta.persistence.*;
import lombok.*;

@Entity
@Table(name = "leave_types")
@Data
@NoArgsConstructor
@AllArgsConstructor
@Builder
public class LeaveTypeDO {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    private String name; // e.g., Annual Leave, Sick Leave
    private Long minServiceMonths; //Months
    private Long maxServiceMonths; //Months
    private Integer maxDays;
    private String expiryDate;
}

This is the app that I run

package com.hr_software_project.hr_management;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@SpringBootApplication
@EnableJpaRepositories
@EntityScan(basePackages = "com.hr_software_project.hr_management.entity")
public class HrManagementApplication {

    public static void main(String[] args) {
        SpringApplication.run(HrManagementApplication.class, args);
    }

}
