帶注釋的推土機深度映射

Question

無法將源類的深度映射映射到Target類SourceEmployee.Address.houseName到TargetEmployee.houseName

源對象類

public class SourceEmployee 
{   
    private String empName;
    private Address addr;


    enter code here

    @Mapping("empName")
    public String getEmpName() {
        return empName;
    }
    public void setEmpName(String empName) {
        this.empName = empName;
    }   
    public Address getAddr() {
        return addr;
    }

    public void setAddr(Address addr) {
        this.addr = addr;
    }   
}

地址類

public class Address 
{
    private String houseName;
    public String getHouseName() {
        return houseName;
    }
    public void setHouseName(String houseName) {
        this.houseName = houseName;
    }
}

目標對象

public class TargetEmployee 
{

    private String empName;
    private String houseName;

    public String getHouseName() {
        return houseName;
    }
    public void setHouseName(String houseName) {
        this.houseName = houseName;
    }
    public String getEmpName() {
        return empName;
    }
    public void setEmpName(String empName) {
        this.empName = empName;
    }
}

主類從源復制到目標

public class CopyAttributes 
{

    public static void main(String args[])
    {
        SourceEmployee sourceEmp = new SourceEmployee();
        sourceEmp.setEmpName("Rafi");

        Address adr = new Address();        
        adr.setHouseName("Aashiyana");
        sourceEmp.setAddr(adr);

        Mapper mapper = new DozerBeanMapper();
        TargetEmployee destObject = mapper.map(sourceEmp, TargetEmployee.class);

        System.out.println(destObject.getEmpName());
        System.out.println(destObject.getHouseName());

    }
}

Answer 1

如果其他人遇到同樣的問題，我設法通過這樣做來糾正這種情況：

public class TargetEmployee 
{

    private String empName;
    private String houseName;

    @Mapping("addr.houseName")
    public String getHouseName() {
        return houseName;
    }
    public void setHouseName(String houseName) {
        this.houseName = houseName;
    }
    public String getEmpName() {
        return empName;
    }
    public void setEmpName(String empName) {
        this.empName = empName;
    }
}

該

@Mapping("empName")

在SourceEmployee中設置沒有必要

Answer 2

它足以在源類中添加此注釋（SourceEmployee）：

@Mapping("this")
private Address addr;

事實上，“這個”意味着“保持在同一個節點上”; 之后，houseName將匹配Address和TargetEmployee。
