DTO转换为实体，反之亦然

我想您是在询问在哪里编写整个实体-> DTO转换逻辑。

像你的实体

class StudentEntity { int age ; String name; //getter //setter public StudentDTO _toConvertStudentDTO(){    StudentDTO dto = new StudentDTO();    //set dto values here from StudentEntity    return dto; }}

您的DTO应该像

class StudentDTO  { int age ; String name; //getter //setter public StudentEntity _toConvertStudentEntity(){    StudentEntity entity = new StudentEntity();    //set entity values here from StudentDTO    return entity ; }}

你的控制器应该像

@Controllerclass MyController {    public String my(){    //Call the conversion method here like    StudentEntity entity = myDao.getStudent(1);    StudentDTO dto = entity._toConvertStudentDTO();    //As vice versa    }}
