Question

我正在尝试将border-width类的值复制到StudentRequestForm类。保存所有值，但StudentEntity中的classI字段未保存，映射到{ {1}} studentBean。我希望我的ClassI值复制到classId

您可以在下面的推土机映射中登记

StudentEntity

推土机映射

classId

controller methood

public class StudentRequestForm {

        private StudentModel studentbean;

        public StudentModel getStudentbean() {
            return studentbean;
        }
        public void setStudentbean(StudentModel studentbean) {
            this.studentbean = studentbean;
        }`enter code here`




public class StudentModel {

    private int countryId,cityId,stateId,classI;
    private String enrollmentId,firstName,lastName,gender,category,pincode,sectionName;



@Entity
@Table(name="students")
public class StudentEntity implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int id;

    private int age;

    private String category;

    private String pincode;

    private int cityId;

    @Column(name="class_id")
    private int classId;

    @Column(name="country_id")
    private int countryId;



        @Column(name="first_name")
    private String firstName;

    private String gender

Answer 1

您正在将StudentModel类传递给Dozer，但在您的映射中，您正在使用StudentRequestForm。所以，要么这样做

StudentEntity studententity = mapper.map(studentForm, StudentEntity.class);

OR

    <class-a>com.myschool.entity.StudentModel</class-a>
    <class-b>com.myschool.entity.StudentEntity</class-b>

    <field>
         <a>classI</a>   
        <b>classId</b>
    </field>

推土机映射不适用于嵌套对象
