Spring核心编程思想(十)重新认识 IoC之轻量级 IoC 容器

小马哥课程笔记

轻量级 IoC 容器

《Expert One-on-One™ J2EE™ Development without EJB™》认为轻量级容器的特征：

• A container that can manage application code.
• A container that is quick to start up.
• A container that doesn’t require any special deployment steps to deploy objects within it.
• A container that has such a light footprint and minimal API dependencies that it can be run in a variety of environments.
• A container that sets the bar for adding a managed object so low in terms of deployment effort and performance overhead that it’s possible to deploy and manage fine-grained objects, as well as coarse-grained components.

《Expert One-on-One™ J2EE™ Development without EJB™》认为轻量级容器的好处：

• Escaping the monolithic container
• Maximizing code reusability
• Greater object orientation
• Greater productivity
• Better testability
