DefaultLobHandler should honour "wrapAsLob" for getting data too [SPR-5376]

[spring-projects-issues]

Antoni Reus opened SPR-5376 and commented

"wrapAsLob" was added in #7007 to DefaultLobHandler to make it work with Postgresql BLOBs.

But this setting is only used for setBlobAsBytes/setBlobAsBinaryStream. So saving a byte[] field in a Postgresql BLOB works well.
But retrieving data doesn't work, it returns the "oid" number as a byte[].

Methods getBlobAsBytes and getBlobAsBinaryStream of DefaultLobHandler should use getBlob if wrapAsLob is set to true.

Thanks for pointing this out! As of 3.0 M2, DefaultLobHandler uses explicit Blob/Clob access for reading when "wrapAsLob"=true.
