Apache CXF & Lazy Loading

[Tom Cassimon <to...@gmail.com>]

Hi,

I use the combination Hibernate, Spring & Apache CXF and I am wondering
if Apache CXF supports lazy loading, and if it does how do i configure it.

I have Entity class with a BLOB column (defined as byte[]). It's annotated
with:

 

    @Column(name = "data", columnDefinition="longblob")

    @Basic(fetch=FetchType.LAZY)

 

But when I am on client side and look at the messages coming in & out it
requests
the lazy loaded variable directly with the first call. Can I somehow define
it as lazy
loaded in Apache CXF (or maybe spring)?

 

Regards,

 

Tom

In general your JDBC driver's concrete implementation of Blob should itself
provide lazy loading.

That is, if you have a setter for the blob, hibernate sets the Blob, the the
stream is not read until you call getBlob().getInputSream().readXXX();

HOWEVER.  In my case I was doing the following in the setter:

dataSource = new AttachmentDataSource("application/octet-stream",
blob.getInputStream());

And the AttachmentDataSource was reading the entire Blob, hence no lazy
loading.   This was fixed though, when I upgraded from CXF 2.2.2 to to
2.2.3.
