How Map two related Entities to one DTO Object using ModelMapper

I have two related Entities in my application integratorDetails, IntegratorChannelDetails. What I want to achieve is to map integratorDetails and IntegratorChannelDetails to a DTO Object IntegratorAllInfoDto which has similar fields as the entities, using ModelMapper, but I am not sure how to do that, below are the entities

integratorDetails

import com.couchbase.client.java.repository.annotation.Field;

import com.couchbase.client.java.repository.annotation.Id;
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.data.couchbase.core.mapping.Document;

import java.util.Date;
import java.util.List;

@Document
@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class IntegratorDetails {
	@Id
	private String integratorId;
	@Field
	private String name;
	@Field
	private String accountId;
	@Field
	private String status;
	private String privateKey;
	private String publicKey;
	private List<ThirdPartyKey> thirdPartyKey;
    private Date createdTime;


}

IntegratorChannelDetails

import com.couchbase.client.java.repository.annotation.Id;
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.data.couchbase.core.mapping.Document;

import java.util.List;

@Document
@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class IntegratorChannelDetails {
	@Id
	private String integratorChannelid;
	private String accountId;
	private String type;
	private List<ChannelType> channelTypes;
	private List<ChannelList> channelList;
	private List<String> fixedChannels;
	private String timeServiceUrl;
	private List<RibbonRules> ribbonRules;
	int numberOfSlots=4;


}

And my Dto is

import com.tdchannels.admin.ms.channel.db.entity.ChannelList;
import com.tdchannels.admin.ms.channel.db.entity.RibbonRules;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.util.Date;
import java.util.List;

@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class IntegratorAllInfoDto<T> {

	private String integratorId;
	private String name;
	private String accountId;
	private String status;
	private Date createdTime;
	private List<ChannelTypeDto> channelTypes;
	private List<ChannelList> channelList;
	private List<String> fixedSlots;
	private String publicKey;
	private List<ThirdPartyKeyDto> thirdPartyKey;
	private List<RibbonRules> ribbonRules;

}

If you need to map multible objects into a single destination you do like this.

ModelMapper modelMapper = new ModelMapper();
IntegratorDTO dto= modelMapper.map(details, IntegratorDTO.class);
//This will add additional values to the dto.
modelMapper.map(integratorChannelDetails, dto);

Like the documentation http://modelmapper.org/getting-started/

You can concat the names of entities on DTO, like:

Source model

// Assume getters and setters on each class
class Order {
  Customer customer;
  Address billingAddress;
}

class Customer {
  Name name;
}

class Name {
  String firstName;
  String lastName;
}

class Address {
  String street;
  String city;
}

Destination Model

// Assume getters and setters
class OrderDTO {
  String customerFirstName;
  String customerLastName;
  String billingStreet;
  String billingCity;
}
