spring MVC源码探究之AbstractHandlerMethodMapping
AbstractHandlerMethodMapping 是什么
解释是这样的。
/**
- Abstract base class for {ink HandlerMapping} implementations that define
- a mapping between a request and a {link HandlerMethod}.
-
For each registered handler method, a unique mapping is maintained with
- subclasses defining the details of the mapping type {ode }.
- param The mapping for a {ink HandlerMethod} containing the conditions
- needed to match the handler method to incoming request.
*/
public abstract class AbstractHandlerMethodMapping extends AbstractHandlerMapping implements InitializingBean
复制代码
我的了解为AbstractHandlerMethodMapping为每个注册的handler method，关于每个子类映射类型都维护着其独一的一个映射，就是维护handler method 和URL的关系。主要用于Controller,RequestMapping 等注解
AbstractHandlerMethodMapping 完成了InitializingBean接口，InitializingBean是在程序启动的时分执行其独一的afterPropertiesSet()办法，那我们就先看一下启动时分的要做哪些操作。
