方法详细资料

• fromContextPath

  public static ServletUriComponentsBuilder fromContextPath​(HttpServletRequest request)

  Prepare a builder from the host, port, scheme, and context path of the given HttpServletRequest.

• fromServletMapping

  public static ServletUriComponentsBuilder fromServletMapping​(HttpServletRequest request)

  Prepare a builder from the host, port, scheme, context path, and servlet mapping of the given HttpServletRequest.

  If the servlet is mapped by name, e.g. "/main/*", the path will end with "/main". If the servlet is mapped otherwise, e.g. "/" or "*.do", the result will be the same as if calling fromContextPath(HttpServletRequest).
