Christofer Dutz commented on PLC4X-224:
---------------------------------------
I would prefer to have a component that compares the map of properties and to
have annotations to ignore a given property. As this way it reduces the amount
of individual driver logic a developer has to implement for every driver.
> Add URI normalization method for Connection Strings for PooledDriverManager
> ---------------------------------------------------------------------------
>
> Key: PLC4X-224
> URL: https://issues.apache.org/jira/browse/PLC4X-224
> Project: Apache PLC4X
> Issue Type: Improvement
> Affects Versions: 0.7.0
> Reporter: Julian Feinauer
> Priority: Major
>
> Currently, one could write two "identical" connections with different
> connection strings, e.g.
> {code:java}
> s7://127.0.0.1?rackId=0&slotId=1
> {code}
> and
> {code:java}
> s7://127.0.0.1?slotId=1&rackId=0{code}
> If the connection Pool only looks at String comparison he would open two
> connetions as the strings are different.
> Thus each Connection should have a way to normalize its strings (also paste
> in all defaults) so that two Connection Stirngs beeing equal means the
> Connections are equal and can be shared.
> See PoolKeyFactory.java L44ff
