JavaBean和POJO有什么区别？ [英] What is the difference between a JavaBean and a POJO?

问题描述

我不确定区别。我正在使用Hibernate，在某些书中，他们使用JavaBean和POJO作为可互换的术语。我想知道是否存在差异，不仅仅是在Hibernate上下文中，而是作为一般概念。

I'm not sure about the difference. I'm using Hibernate and, in some books, they use JavaBean and POJO as an interchangeable term. I want to know if there is a difference, not just in the Hibernate context, but as general concepts.

推荐答案

遵循JavaBean某些惯例。 Getter / setter命名，具有公共默认构造函数，可序列化等。请参阅 JavaBeans约定以获取更多详细信息。

A JavaBean follows certain conventions. Getter/setter naming, having a public default constructor, being serialisable etc. See JavaBeans Conventions for more details.

未严格定义POJO（普通旧Java对象）。它是一个Java对象，它不需要实现特定的接口或从特定的基类派生，或者使用特定的注释以便与给定的框架兼容，并且可以是任意的（通常相对简单） Java对象。

A POJO (plain-old-Java-object) isn't rigorously defined. It's a Java object that doesn't have a requirement to implement a particular interface or derive from a particular base class, or make use of particular annotations in order to be compatible with a given framework, and can be any arbitrary (often relatively simple) Java object.
