--------------------------------
Summary: [Java Broker] Add support for POST method into REST
interfaces in order to create configured objects via POST
Key: QPID-6438
URL: https://issues.apache.org/jira/browse/QPID-6438
Project: Qpid
Issue Type: Bug
Components: Java Broker
Affects Versions: 0.30, 0.28, 0.26, 0.24, 0.22, 0.20, 0.18, 0.32
Reporter: Alex Rudyy
Assignee: Alex Rudyy
Fix For: 6.0 [Java]
PUT method requests are used for both configured object creation and their
updates. Our REST layer looks for ID or name( coupled with object parent) in
order to decide whether it is an update request or not.
Update is made when object with the same id or the same name and parent is
found. Otherwise a new object is created.
On creation of new configured objects(for example, virtual host nodes) the same
name as existing object can be specified by mistake. As result, an update
request is performed causing updating attributes in existing object and saving
those attributes in the database. In practice, it might cause configuration
issues, for instance,
if user tries to create a new BDB HA VHN and specifies an existing VHN name,
the existing VHN attributes are updated and on next broker restart a new VHN
with a new store can be created.
In many REST best practices it is recommended to use POST requests to create
REST resources and PUT requests to update/create resources.
We can use the same approach in the Qpid REST layer, i.e. send POST requests if
we definitely want to create new objects via web management console or REST
