说明

1.通过脚本语言让JAVA执行动态代码

2.用Spring可以将脚本语言代理成Java接口的实现类

3.Spring2.5.6中支持三种脚本语言ruby,Groovy,BeanShell

4.示例中为spring与beanshell结合

5.依赖spring2.5.6,bsh-2.0b4

复制代码 代码如下:

import org.junit.Test;

import org.springframework.scripting.bsh.BshScriptUtils;

import bsh.EvalError;

public class TestBeanShell {

@Test

public void testShell() {

String srciptText = "say(name){ return "hello,"+name;}";

SayHello sh;

try {

sh = (SayHello) BshScriptUtils.createBshObject(srciptText, new Class[] { SayHello.class });

String res=sh.say("vidy");

System.out.println(res);

} catch (EvalError e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

interface SayHello {

public String say(String name);

}
