Enforcing input validation through aspect oriented programming

Implementations of the present disclosure include methods, systems, and computer readable storage mediums for validating input parameters provided to an application, including executing the application using the one or more processors, collecting one or more validation aspects associated with the application to provide a set of validation aspects, receiving a first input parameter that is associated with a first validation point, extracting a first data type of the first input parameter, and determining that a validation aspect corresponding to the first data type is available in the set of validation aspects and, in response, applying a corresponding validation function to the first input parameter.
