注入的是支持的貨幣類型，是一個set類型

定義module綁定

package?org.demo.guicedemo.server.impl;

import?com.google.inject.AbstractModule;
import?com.google.inject.multibindings.Multibinder;

public?class?ChinaModule?extends?AbstractModule?{

	@Override
	protected?void?configure()?{
		//?Adds?CNY?support
		Multibinder.newSetBinder(binder(),?String.class)
			.addBinding().toInstance("CNY");

	}

}

就會往集合中添加值CNY

package?org.demo.guicedemo.server.impl;

import?com.google.inject.AbstractModule;
import?com.google.inject.multibindings.Multibinder;

public?class?GlobalModule?extends?AbstractModule?{

	@Override
	protected?void?configure()?{
		//?Adds?EUR,?USD?support
		Multibinder<String>?currencyBinder?=
				Multibinder.newSetBinder(binder(),?String.class);
		currencyBinder.addBinding().toInstance("EUR");
		currencyBinder.addBinding().toInstance("USD");
	}

}

就會往集合中添加值EUR和USD
