  HandlesTypes
  This annotation is used to declare an array of application classes which are passed to a `ServletContainerInitializer`.
  HttpConstraint
  This annotation represents the security constraints that are applied to all requests with HTTP protocol method types that are not otherwise represented by a corresponding `HttpMethodConstraint` in a `ServletSecurity` annotation.
  HttpMethodConstraint
  Specific security constraints can be applied to different types of request, differentiated by the HTTP protocol method type by using this annotation inside the `ServletSecurity` annotation.
  MultipartConfig
  This annotation is used to indicate that the `Servlet` on which it is declared expects requests to made using the `multipart/form-data` MIME type.
  ServletSecurity
  Declare this annotation on a `Servlet` implementation class to enforce security constraints on HTTP protocol requests.
  The container applies constraints to the URL patterns mapped to each Servlet which declares this annotation.
  ServletSecurity.EmptyRoleSemantic
  Represents the two possible values of the empty role semantic, active when a list of role names is empty.
  ServletSecurity.TransportGuarantee
  Represents the two possible values of data transport, encrypted or not.
  WebFilter

  WebInitParam

  E.g.
