问题 I have class A (domain class), class B (mongo db repository layer class) extends A and both of them have Lombok @Builder on them. I need to convert between them and when I use Mapstruct for this, the implementation conversion class uses Builder from A when generating object of type B. This results in build failure due to "incompatible types". How to fix this? @Builder class A { } @Document @Builder class B extends A{ } @Mapper public interface ClassMapper { B mapToDocument(A domainObject); }

问题 In my project, lombok is used to avoid writing getters and setters for a class. I have two classes Child extends Parent : @Value @Builder @AllArgsConstructor @JsonIgnoreProperties(ignoreUnknown = true) public class Parent { @Nonnull @JsonProperty("personId") private final String personId; @JsonProperty("personTag") private final String personTag; ... } And @Value @Builder @AllArgsConstructor @JsonIgnoreProperties(ignoreUnknown = true) public class Child extends Parent { @Nonnull @JsonProperty

每一个成功者都有一个开始。勇于开始，才能找到成功的路。你好，我是梦阳辰！期待与你相遇！ Mybatis从浅入深（IDEA版通俗易懂） 01.使用注解开发引入：大家之前都学过面向对象编程，也学习过接口，但在真正的开发中，很多时候我们会选择面向接口编程根本原因∶解耦，可拓展，提高复用，分层开发中，上层不用管具体的实现，大家都遵守共同的标准，使得开发变得容易，规范性更好在一个面向对象的系统中，系统的各种功能是由许许多多的不同对象协作完成的。在这种情况下，各个对象内部是如何实现自己的,对系统设计人员来讲就不那么重要了; 而各个对象之间的协作关系则成为系统设计的关键。小到不同类之间的通信，大到各模块之间的交互，在系统设计之初都是要着重考虑的，这也是系统设计的主要工作内容。面向接口编程就是指按照这种思想来编程。关于接口的理解接口从更深层次的理解，应是定义(规范，约束）与实现(名实分离的原则）的分离。-接口的本身反映了系统设计人员对系统的抽象理解。接口应有两类: 第一类是对一个个体的抽象，它可对应为一个抽象体(abstract class); 第二类是对一个个体某一方面的抽象，即形成一个抽象面(interface) ; 一个体有可能有多个抽象面。抽象体与抽象面是有区别的。三个面向的区别：面向对象是指，我们考虑问题时，以对象为单位，考虑它的属性及方法．面向过程是指
