How to use ModelMapper in Spring Boot

     

Step 1: Add given dependency in pom.xml file.

<dependency>
   <groupId>org.modelmapper</groupId>
   <artifactId>modelmapper</artifactId>
</dependency>

Step 2: Go to your main file and copy & paste given code.

import org.modelmapper.ModelMapper;
import org.springframework.context.annotation.Bean;

@Bean
public ModelMapper modelMapperBean() { 
   return new ModelMapper(); 
}

Step 3: Go to your file where you want to map one object data to another object.

@Autowired
private ModelMapper modelMapper;

Step 4: For single object mapping

UserDto userDTO = modelMapper.map(user, UserDTO.class);

Step 5:  For list Object mapping

List<UserDto> userDtoList= modelMapper.map(userList, new TypeToken<List<UserDto>>() {}.getType());

NOTE:-

  • UserDto is the blank object.
  • user is the object where data is available.
  • So here we are mapping user data to UserDto.
