獲取spring中所有定義了的requestMapping信息

  獲取spring中所有定義了的requestMapping信息

  前置條件：

  所在bean實現ApplicationContextAware接口

  擁有屬性private Set<String> requestMappings = new HashSet<>(500);

  

  實現過程：

  

@Override
  public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
    AbstractHandlerMethodMapping<RequestMappingInfo> methodMapping = (AbstractHandlerMethodMapping<RequestMappingInfo>) applicationContext.getBean("requestMappingHandlerMapping");
    Map<RequestMappingInfo, HandlerMethod> mapRet = methodMapping.getHandlerMethods();
    mapRet.keySet().forEach(requestMappingInfo -> requestMappings.add(requestMappingInfo.toString()));
  }

  @GetMapping("obtain.request.mapping")
  public R obtainRequestMapping() {
    return R.success(requestMappings);
  }

 

  如果拿不到bean用

AbstractHandlerMethodMapping<RequestMappingInfo> methodMapping = (AbstractHandlerMethodMapping<RequestMappingInfo>) applicationContext.getBean(RequestMappingHandlerMapping.class.getName());

獲取：{{url}}/obtain.request.mapping
