Context Hierarchy
上下文层次图
| Bean Type | Explanation |
|---|---|
| HandlerMapping | Map a request to a handler along with a list of interceptors for pre- and post-processing. The mapping is based on some criteria, the details of which vary by HandlerMapping implementation. The two main HandlerMapping implementations are RequestMappingHandlerMapping (which supports @RequestMapping annotated methods) and SimpleUrlHandlerMapping (which maintains explicit registrations of URI path patterns to handlers). |
| HandlerAdapter | Help the DispatcherServlet to invoke a handler mapped to a request, regardless of how the handler is actually invoked. For example, invoking an annotated controller requires resolving annotations. The main purpose of a HandlerAdapter is to shield the DispatcherServlet from such details. |
| HandlerExceptionResolver | Strategy to resolve exceptions, possibly mapping them to handlers, to HTML error views, or other targets. See Exceptions. |
| HandlerMapping | Resolve logical String-based view names returned from a handler to an actual View with which to render to the response. See View Resolution and View Technologies. |
| ViewResolver | Resolve logical String-based view names returned from a handler to an actual View with which to render to the response. See View Resolution and View Technologies. |
| LocaleResolver, LocaleContextResolver | Resolve the Locale a client is using and possibly their time zone, in order to be able to offer internationalized views. See Locale. |
| ThemeResolver | Resolve themes your web application can use — for example, to offer personalized layouts. See Themes. |
| MultipartResolver | Abstraction for parsing a multi-part request (for example, browser form file upload) with the help of some multipart parsing library. See Multipart Resolver. |
| FlashMapManager | Store and retrieve the “input” and the “output” FlashMap that can be used to pass attributes from one request to another, usually across a redirect. See Flash Attributes. |
