Spring Groovy Setter Injection

Following is the implementation of scripting of beans setter injection in spring using groovy script.

Implementation:

Drink:

package com.lnn.groovy;

public interface Drink {

  public void drink();

}

Drinker:

package com.lnn.groovy;

public class Drinker {

      private Drink drink;

      public void setDrink(Drink drink) {

            this.drink = drink;

      }

      public void drink() {

            System.out.println("Drinking from Java!");

            drink.drink();

      }

}

MyDrink.groovy:

class MyDrink implements com.lnn.groovy.Drink {

    void drink() {

      print content;

    }   

    String content;

}

Groovy.xml:

<beans xmlns="http://www.springframework.org/schema/beans"

      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:lang="http://www.springframework.org/schema/lang"

      xsi:schemaLocation="

      http://www.springframework.org/schema/beans

      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

      http://www.springframework.org/schema/lang

      http://www.springframework.org/schema/lang/spring-lang-3.0.xsd">

      <bean id="drinker" class="com.lnn.groovy.Drinker">

            <property name="drink" ref="drink" />

      </bean>

      <lang:groovy id="drink" script-source="classpath:com/lnn/groovy/MyDrink.groovy">

            <lang:property name="content" value="Drinking from Groovy using Setter!" />

      </lang:groovy>

</beans>

GroovyTest.java:

package com.lnn.groovy;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class GroovyTest {

      public static void main(String[] args) {

            ApplicationContext context = new ClassPathXmlApplicationContext("groovy.xml");

            Drinker drinker = (Drinker) context.getBean("drinker");

            drinker.drink();

      }

}
