java动态调用groovy代码

pom文件引入groovy包

1<dependency>
2      <groupId>org.codehaus.groovy</groupId>
3      <artifactId>groovy-all</artifactId>
4      <version>2.5.5</version>
5    </dependency>

java接口

1package com.yydone.test;
2
3interface IFoo {
4    Object add(Object x, Object y);
5}

groovy实现类，实现IFoo接口

1package com.yydone.test
2
3class Foo implements IFoo {
4    Object add(Object x, Object y) {
5        return x + y
6    }
7}

java测试类

1package com.yydone.test;
2
3import groovy.lang.GroovyClassLoader;
4
5public class GroovyClassLoaderExample {
6
7    public static void main(String[] args) {
8        try {
9            Class clazz;
10            try (GroovyClassLoader loader = new GroovyClassLoader()) {
11                clazz = loader.loadClass("com.yydone.test.Foo");
12            }
13            IFoo foo = (IFoo) clazz.newInstance();
14            System.out.println( foo.add(new Integer(2), new Integer(3)));
15        } catch (Exception e) {
16            e.printStackTrace();
17        }
18    }
19}
