Class SpringExceptionMapper

java.lang.Object

com.sap.cloud.sdk.cloudplatform.servlet.response.AbstractExceptionMapper<SpringExceptionMapper>

com.sap.cloud.sdk.frameworks.spring.response.SpringExceptionMapper

@ControllerAdvice
public class SpringExceptionMapper
extends AbstractExceptionMapper<SpringExceptionMapper>

Global exception handler using the Spring ControllerAdvice mechanic.

This handler catches all Throwables, logs them on the server side, and fills the response with the status code and error description. To change/override this behavior either use the methods defined in the AbstractExceptionMapper, or write a custom mapper with the ControllerAdvice annotation and a Priority higher then the default one.

Note that CloudLoggerFactory is not used here to avoid recursion.
