Spring集成Groovy

Spring集成Groovy

2.0 M2 新增Package org.springframework.scripting, 集成了bsh, groovy, jruby, 这里只关心groovy

1. xml

< bean  class ="org.springframework.scripting.support.ScriptFactoryPostProcessor" />

     < bean  id ="calculator"  class ="org.springframework.scripting.groovy.GroovyScriptFactory" >
         < constructor-arg >
             < value > inline:
package org.springframework.scripting.groovy;
import org.springframework.scripting.Calculator
class GroovyCalculator implements Calculator {
    int add(int x, int y) {
       return x + y;
    }
}
             </ value >
         </ constructor-arg >
     </ bean >

     < bean  id ="messenger"  class ="org.springframework.scripting.groovy.GroovyScriptFactory" >
         < constructor-arg  value ="classpath:org/springframework/scripting/groovy/Messenger.groovy" />
         < property  name ="message"  value ="Hello World!" />
     </ bean >

在xml中写groovy, 灵活得有点过头(维护麻烦)

2. groovy

package  org.springframework.scripting.groovy;

import  org.springframework.scripting.Messenger

class  GroovyMessenger  implements  Messenger {

    @Property String message;
}

3. test case

ApplicationContext ctx  =
                 new  ClassPathXmlApplicationContext( " org/springframework/scripting/groovy/groovyContext.xml " );
        Calculator calc  =  (Calculator) ctx.getBean( " calculator " );
        Messenger messenger  =  (Messenger) ctx.getBean( " messenger " );
