<artifactId>java-object-diff</artifactId> <version>2.0.0</version> </dependency> 在导入依赖项后,我们就可以开始使用ObjectDifferBuilder类了。 第二步:创建对象示例 在使用ObjectDifferBuilder类之前,我们需要创建要比较的两个对象的示例。让我们假设我们正在开发一个电子商务网站,我们有一个Product类来表示商品...
protected Object clone() 创建并返回此对象的副本。 public boolean equals(Object obj)`:指示其他某个对象是否与此对象“相等”。 protected void finalize() 当垃圾收集确定不再有对该对象的引用时,垃圾收集器在对象上调用该对象。 类<?> getClass() 返回此 Object的运行时类。 int hashCode() 返回对象的哈希...
使用JaVers比较差异 最后,我们使用JaVers框架来比较两个User对象之间的差异。 publicclassUserUtils{publicstaticvoidcompareUsers(Useruser1,Useruser2){Javersjavers=JaversBuilder.javers().build();Diffdiff=javers.compare(user1,user2);List<Change>changes=diff.getChanges();for(Changechange:changes){System.out.p...
java-object-diffis a simple, yet powerful library to find differences between Java objects. It takes two objects and generates a tree structure that represents any differences between the objects and their children. This tree can then be traversed to extract more information or apply changes to ...
