运行String中包含的一段代码 [英] Run piece of code contained in a String

问题描述

我在String中有一段Java代码。

I have a piece of Java code in a String.

String javaCode = "if(polishScreenHeight >= 200 && " +
    "polishScreenHeight <= 235 && polishScreenWidth >= 220) { }";

是否可以将此Java字符串转换为Java语句并运行它？可能使用Java反射？

Is it possible to convert this Java String to a Java statement and run it? Possibly using Java reflection?

推荐答案

正如已经建议的那样，您可以使用编译器API 。

As has already been suggested you can compile, save and run code on the fly using the Compiler API.

另一个简洁的选择是使用 beanshell 。 Beanshell不再积极开发，但我可以保证它的可靠性，我已经在多个生产项目中成功使用它。

Another neat alternative would be to use beanshell. Beanshell is no longer actively developed, but I can vouch for it's reliability, I've used it successfully in multiple production projects.
