最近项目上用到了一些Deep Clone的库,但是原来使用的库速度略慢,直接拖累了应用。 今天有空看了一下相关的可用的第三方库。 深拷贝 Apache旗下的Commons-Lang3包有一个序列化的工具SerializationUtils,可以做深拷贝。 当然前提是你的类实现了序列化接口。 Java Deep Cloning Library是我觉得最好用的一个。它的深...
The cloning library is a small, open source (Apache licensed) Java library which deep-clones objects. The objects don't have to implement the Cloneable interface. Effectively, this library can clone ANY Java object. It can be used i.e. in cache implementations if you don't want the cached...
在Java 中,对象克隆指的是创建一个现有对象的副本。该副本具有与原始对象相同的状态和属性,但在内存中两者是独立存在的,针对其中一个对象的修改不会影响到另一个对象。 要使一个类能够被克隆,需要满足以下条件: 实现Cloneable接口 Cloneable是一个标记接口,没有任何方法,实现了该接口,即表示该类可以被克隆。 Clonea...

Kryo can also perform automatic deep and shallow copying/cloning. This is direct copying from object to object, not object to bytes to object. This documentation is for Kryo version 5.x. See the Wiki for version 4.x. Contact / Mailing list Please use the Kryo mailing list for questions,...
Note that this method works fine when the class you want to deep copy is serializable and all of it’s variables are also Serializable. Otherwise it will not work and you will getjava.io.NotSerializableException. 请注意,当要深度复制的类可序列化并且其所有变量也可序列化时,此方法可以正常工作。
1. Introduction A copy constructor in a Java class is aconstructorthatcreates an object using another object of the same Java class. That's helpful when we want to copy a complex object that has several fields, or when we want to make adeep copyof an existing object. ...

Learn to serialize HashMap using Google Gson library. Also, learn to deserialize JSON string to HashMap containing custom Objects using Gson such that field values are copied into appropriate generic types. These conversions can be used to create deep cloning of the HashMap. 1. Maven Include th...
Simple alternative to cloning, especially when using library such as Apache Commons Provides deep cloning Suitable even for complex object graphs Can be used on existing classes that currently provide just shallow copy This also has some limitations and disadvantages: ...
