Conversion of DTO to entity and vice-versa
java, jpa, spring-mvc
Solution
I think you are asking about where to write whole entity-->DTO conversion logic.
Like Your entity
class StudentEntity {
int age ;
String name;
//getter
//setter
public StudentDTO _toConvertStudentDTO(){
StudentDTO dto = new StudentDTO();
//set dto values here from StudentEntity
return dto;
}
}
Your DTO Should be like
class StudentDTO {
int age ;
String name;
//getter
//setter
public StudentEntity _toConvertStudentEntity(){
StudentEntity entity = new StudentEntity();
//set entity values here from StudentDTO
return entity ;
}
}
And Your Controller should be like
@Controller
class MyController {
public String my(){
//Call the conversion method here like
StudentEntity entity = myDao.getStudent(1);
StudentDTO dto = entity._toConvertStudentDTO();
//As vice versa
}
}
Problem
I am using `Spring MVC` architecture with `JPA` in my web application. Where to convert data transfer object (DTO) to JPA entity and vice-versa, manually (that is, without using any framework)?
