    • doWithExceptionWrapper

      public static <T> T doWithExceptionWrapper(Supplier<T> supplier)
      Pass logic, which directly calls MyBatis API. In case a MyBatis exception is thrown, it is wrapped into a ProcessEngineException and never propagated directly to an Engine API call. In some cases, the top-level exception and its message are shown as a response body in the REST API. Wrapping all MyBatis API calls in our codebase makes sure that the top-level exception is always a ProcessEngineException with a generic message. Like this, SQL details are never disclosed to potential attackers.
      Type Parameters:
      T - is the type of the return value
      Parameters:
      supplier - which calls MyBatis API
      Returns:
      the value returned by the supplier
      Throws:
      ProcessEngineException - which wraps the actual exception
