Interface ConnectionAccessor

All Superinterfaces:

ConnectionAccessor

Deprecated.

since 1.2, use Spring R2DBC's DatabaseClient support instead.

public interface ConnectionAccessor
extends ConnectionAccessor

Interface declaring methods that accept callback Function to operate within the scope of a Connection. Callback functions operate on a provided connection and must not close the connection as the connections may be pooled or be subject to other kinds of resource management.

Callback functions are responsible for creating a Publisher that defines the scope of how long the allocated Connection is valid. Connections are released after the publisher terminates.
