SpringMVC获取注解RequestMapping

在实现用户权限管理模块的时候，我希望能将所有配置的action存储到行为表中，便于细粒度控制行为的权限．由于controller使用的是springMVC实现的，所以我希望在项目启动时，能够先获取到项目中所有配置的RequestMapping，存储到数据库中．

1.servlet

public class GetAllRequestMappingTest extends HttpServlet  {private static final long serialVersionUID = 1L;public void init(ServletConfig config) throws ServletException {System.out.println("GetAllRequestMappingTest in");ServletContext context = config.getServletContext();WebApplicationContext webApp =  WebApplicationContextUtils.getRequiredWebApplicationContext(context); RequestMappingHandlerMapping rmhp = webApp.getBean(RequestMappingHandlerMapping.class);          Map<RequestMappingInfo, HandlerMethod> map = rmhp.getHandlerMethods();          for (Iterator<RequestMappingInfo> iterator = map.keySet().iterator(); iterator                    .hasNext();) {                RequestMappingInfo info = iterator.next();              System.out.print(info.getConsumesCondition());              System.out.print(info.getCustomCondition());              System.out.print(info.getHeadersCondition());              System.out.print(info.getMethodsCondition());              System.out.print(info.getParamsCondition());              System.out.print(info.getPatternsCondition());              System.out.print(info.getProducesCondition());                System.out.print("===");                          HandlerMethod method = map.get(info);              System.out.print(method.getMethod().getDeclaringClass().getName() + "--");            System.out.print(method.getMethod().getName());              //System.out.print(method.getMethodAnnotation(RequestMapping.class).params()[0]);              System.out.println();          }  }}

3.注意

网上有很多都是把该功能作为一个controller中的一个方法．原因是RequestMappingHandlerMapping这个类只能在controller中获取．在我尝试的过程中确实不在controller中，通过自动注入的方式是无法获得RequestMappingHandlerMapping类的．但是通过全局WebApplicationContext可以不用自动注入的方式获得RequestMappingHandlerMapping类．
