doWithExceptionWrapper
Pass logic, which directly calls MyBatis API. In case a MyBatis exception is thrown, it is wrapped into aProcessEngineException
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 aProcessEngineException
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
-
