Component-based dynamic updating software system
基于组件的动态软件更新

Based on the analysis of the key issues that affect dynamic updating, a component-based dynamic updating mechanism which obtained a safe updating point by interposing interceptor dynamically was presented, and the hot-swapping of dynamic components was achieved. The main procedure included interposing interceptor, blocking invocation, transferring state and redirecting requests. This design makes the apphcation has better feasibihty, expansibility and operation performance.
