public interface RequestCondition<T>
Contract for request mapping conditions.

Request conditions can be combined via combine(Object), matched to a request via getMatchingCondition(RequestContext), and compared to each other via compareTo(Object, RequestContext) to determine which is a closer match for a given request.

    说明
    T
    combine(T other)
    Combine this condition with another such as conditions from a type-level and method-level @RequestMapping annotation.
    int
    compareTo(T other, RequestContext request)
    Compare this condition to another condition in the context of a specific request.
    T
    getMatchingCondition(RequestContext request)
    Check if the condition matches the request returning a potentially new instance created for the current request.

    • combine

      T combine(T other)
      Combine this condition with another such as conditions from a type-level and method-level @RequestMapping annotation.
      参数:
      other - the condition to combine with.
      返回:
      a request condition instance that is the result of combining the two condition instances.

    • getMatchingCondition

      @Nullable T getMatchingCondition(RequestContext request)
      Check if the condition matches the request returning a potentially new instance created for the current request. For example a condition with multiple URL patterns may return a new instance only with those patterns that match the request.

      For CORS pre-flight requests, conditions should match to the would-be, actual request (e.g. URL pattern, query parameters, and the HTTP method from the "Access-Control-Request-Method" header). If a condition cannot be matched to a pre-flight request it should return an instance with empty content thus not causing a failure to match.

      参数:
      request - the current request context
      返回:
      a condition instance in case of a match or null otherwise.

    • compareTo

      int compareTo(T other, RequestContext request)
      Compare this condition to another condition in the context of a specific request. This method assumes both instances have been obtained via getMatchingCondition(RequestContext) to ensure they have content relevant to current request only.
      参数:
      request - the current request context
