java - 将两个具有类似名称字段的 pojo 同步在一起

Question

我有两个pojo。

public class Pojo1 implements Serializable {

    private static final long serialVersionUID = 1302290920579795856L;

    private Long id;
    private String idNumber; 
    private String vendorNumber; 
    private Date expires;

    // Getters and setters for each one
}

public class Pojo2 implements Serializable {

    private static final long serialVersionUID = 1302290920579795856L;

    private Long id;
    private String idNumber; 
    private String vendorNumber; 
    private Date expires;
    private String otherData;

    // Getters and setters for each one
}

是否有 Java API 可用于从 Pojo2 自动创建 Pojo1？

IE：

Pojo1 newPojo1 = SomeLibrary.fromPojoWithLikeNamedFields(pojo2);

// newPojo1 now has all the fields that had the same name from pojo2

Answer 1

复制构造函数不会完成这项工作吗？

public Pojo1(Pojo2 pojo2){
    this.id = pojo2.getId();
    this.idNumber = pojo2.getIdNumber();
    this.vendorNumber = pojo2.getVendorNumber();
    this.expires = pojo2.getExpires();
}

然后就这样使用，

Pojo1 newPojo1 = new Pojo1(pojo2);

还是我误解了什么……？
