public interface speaking {
  public void saying();
}

/**

package com.test.func.impl;

public class JackSpeaking implements speaking{

  /* (non-Javadoc)
   * @see com.test.func.speaking#saying()
   */
  @Override
  public void saying() {
    // TODO Auto-generated method stub
    System.out.println("saying something.......");
  }

}

/**

package com.test.guice;

import com.google.inject.AbstractModule;
import com.test.func.speaking;
import com.test.func.impl.JackSpeaking;

/**

 */
public class Model extends AbstractModule{

  /* (non-Javadoc)
   * @see com.google.inject.AbstractModule#configure()
   */
  @Override
  protected void configure() {
    // TODO Auto-generated method stub
    bind(speaking.class).to(JackSpeaking.class);
  }

}

/**

 */
package com.test.guice;

import com.google.inject.Guice;
import com.google.inject.Injector;
import com.test.func.speaking;

/**
 * @filename Main.java
 * @author code by jianghuiwen
 * @mail jianghuiwen2012@163.com
 *
 * 上午11:23:29
 */
public class Main {

  /**
   * @param args
   */
  public static void main(String[] args) {
    // TODO Auto-generated method stub
    Injector injector = Guice.createInjector(new Model());
    speaking speakingperson = injector.getInstance(speaking.class);
    speakingperson.saying();
    
  }

}

输出结果：

总结：

用了配置话的注入模式，不用再new一个对象，麻烦的地方就是一定要手工的配置public class Model extends AbstractModule这样一个类。
