I apologize if this question has been asked and answered before but:
What is the best-practices solution to redact the database user name and
password from an XML file created and used by Cayenne Modeler? The
ServerRuntime build statement is simply:
cayenneRuntime = ServerRuntime.builder()
.addConfig("com/hulles/a1icia/cayenne/cayenne-a1icia.xml")
.build();
It works just fine as long as the db user name and password are in the
XML file, but I don't believe in leaving clear-text artifacts like that
laying around in the code, so I want to add the user and password data
at runtime from a Java method (not from an external file or an
'executable', whatever that means in the content of PasswordEncoding).
Adding .user("xyz") and .password("zyx") to the build statement don't
work, presumably because the DataNode is not the default and those
statements just set their respective fields for the default DataNode.
If I have to, I can create either a Module to change those properties
somehow at runtime (though the documentation for doing so is, to be
kind, sparse), somehow implement the PasswordEncoding (even less
documentation, because I don't know where it's used), or just edit the
XML at runtime (horrible choice but looking like the best of a bad lot
at this point).
All this seems like a lot of effort when I imagine this need must crop
up fairly often among Cayenne users (it should, for security reasons
IMO). Is there a simple standard way to do what I want? Or at least a
standard way? I don't want to invent a new wheel here. I feel like I'm
missing something obvious that everyone else knows about and that I just
missed. Oh, by the way, whatever the solution is should still allow
Cayenne Modeler to function normally.
I promise I searched for the answer everywhere I could think of.
StackOverflow had a couple answers that used deprecated methods and
didn't work when I tried them.
Thanks in advance for any help. I hope there's a really simple answer so
I feel stupid but don't have to spend any more time on this than I have
already. :)
