Guice

概述:

Guice是一个轻量级，基于Java5（主要运用泛型与注释特性）的依赖注入框架(IOC)。Guice非常小而且快。Guice是类型安全的，它能够对构造函数，属性，方法（包含任意个参数的任意方法，而不仅仅是setter方法）进行注入。Guice还具有一些可选的特性比如：自定义scopes，传递依赖，静态属性注入，与Spring集成和AOP联盟方法注入等。

Guice (pronounced 'juice') is a lightweight dependency injection framework for Java 5 and above, brought to you by Google.

Guice

Put simply, Guice alleviates the need for factories and the use of new in your Java code. Think of Guice's@Inject as the new new. You will still need to write factories in some cases, but your code will not depend directly on them. Your code will be easier to change, unit test and reuse in other contexts.

Guice embraces Java's type safe nature, especially when it comes to features introduced in Java 5 such as generics and annotations. You might think of Guice as filling in missing features for core Java. Ideally, the language itself would provide most of the same features, but until such a language comes along, we have Guice.

Guice helps you design better APIs, and the Guice API itself sets a good example. Guice is not a kitchen sink. We justify each feature with at least three use cases. When in doubt, we leave it out. We build general functionality which enables you to extend Guice rather than adding every feature to the core framework.

Guice aims to make development and debugging easier and faster, not harder and slower. In that vein, Guice steers clear of surprises and magic. You should be able to understand code with or without tools, though tools can make things even easier. When errors do occur, Guice goes the extra mile to generate helpful messages.

For an introduction to Guice and a comparison to new and the factory pattern, see Bob Lee's video presentation. After that, check out our user's guide.

We've been running Guice in mission critical applications since 2006, and now you can, too. We hope you enjoy it as much as we do.
