如何通过Java反射动态创建Java类？ [英] How to create Java classes Dynamically by Java Reflection?

问题描述

反射用于加载java类类，并在运行时对它们进行操作。但是我遇到了一个奇怪的问题，问我如何通过Reflection即时创建Java类。我的意思是类没有被编译或有源代码，直到我们想要它们被创建。真的有可能吗？任何示例？

解决方案

您可以尝试ASM
ASM

或字节代码工程库

用于操纵，在运行时创建课程

在.NET中，我们有Reflection.Emit（C＃），它可以做到
Reflection.Emit

不知道是否有直接java等效
您可以在此处看到另一个类似的问题：与...相当的反思。 >

Reflection is used to load java class classes and manipulate them on the fly. But I have across a weird question that is asking me how to create Java classes on the fly by Reflection.I mean the classes is not compiled or have source code till we want them created. Is it really possible? Any examples?

解决方案

You can try ASM ASM

or Byte code engineering library

Byte code engineering library

for manipulating, creating classes at run time

In .NET we have Reflection.Emit(C#) which can do that Reflection.Emit

Not sure whether there is a direct java equivalent. You can see another similar question on SO here Java equivalent of reflection.emit
