java的guice3.0依赖注入方法，这里采用的是官方文档的第一种注入方法。

public class Model extends AbstractModule{

@Override
protected void configure() {
// TODO Auto-generated method stub
bind(speaking.class).to(JackSpeaking.class);
}
}
/**

import com.test.func.speaking;

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。
