Java：getter / setter方法

[英]Java: getter/setter methods

原文 2011-03-05 04:56:53 5 1 java/ reflection

How are a bean's getter methods invoked and set in various frameworks? 如何在各种框架中调用和设置bean的getter方法？ is it only through reflections? 只是通过反思？

1 个解决方案

Yes, most frameworks use reflections for that, with assumed requirement that you must use a proper getter / setter naming convention (getXXX and setXXX, or isXXX and setXXX for boolean property). 是的，大多数框架都使用反射，假设您必须使用正确的getter / setter命名约定（getXXX和setXXX，或者isXXX和setXXX用于布尔属性）。

Performance may be an issue, but unless you benchmark your application and find reflections to be a major bottleneck, I would advise against premature optimization, and use reflections as the simplest solution. 性能可能是一个问题，但除非您对应用程序进行基准测试并发现反射是一个主要瓶颈，否则我建议不要过早优化，并使用反射作为最简单的解决方案。 With that said, you may want to look at this article on replacing reflections with code generation: 有了这个，你可能想看看这篇关于用代码生成替换反射的文章：
