peaberry 1.0 RC1：Gucie的动态服务扩展

peaberry 1.0 RC1发布，它是Gucie的一个扩展库，支持动态服务的依赖注入。它为OSGi集成提供了一些创新的技术，而且还为其他的registry-based服务框架提供了插件。它可以被放置到任何R4的框架中，例如：Apache Felix 或 Eclipse/Equinox。

下面我们来看一个例子：

import static org.ops4j.peaberry.Peaberry.service;
import static org.ops4j.peaberry.util.TypeLiterals.export;
import static org.ops4j.peaberry.util.TypeLiterals.iterable;

Injecting a stock quote service

@Inject
StockQuote quote;
...
bind(StockQuote.class).to(service(StockQuote.class).single());

Injecting many stock quote services

@Inject
Iterable<StockQuote> quotes;
...
bind(iterable(StockQuote.class)).to(service(StockQuote.class).multiple());

Exporting an implementation as a stock quote service

@Inject
Export<StockQuote> exportedQuote;
...
bind(export(StockQuote.class)).to(service(myQuoteImpl).export());

Watching for a stock quote service

@Inject
StockQuote quote;
...

// the watching scope is notified as stock services are added, modified, or removed
bind(StockQuote.class).to(service(StockQuote.class).out(watchingScopeImpl).single());
