Teiid spring boot exposing OData and also other rest controllers

[tamarm]

Hi,

I want to expose OData4 in my microservice, and also expose other endpoints which doesn't related to OData(for example - Spring boot actuator endpoints like health check)

I defined server.context-path: /api/odata in my bootstrap.yml file.

Accessing to <my-server-url>/api/odata/health returns the follow response:

<error xmlns="http://docs.oasis-open.org/odata/ns/metadata">

<code>null</code>

<message>

Cannot find EntitySet, Singleton, ActionImport or FunctionImport with name 'health'.

</message>

</error>

Please advice how to configure it if possible,

Thanks

I have not tested with Spring actuator. Can you add a request for this feature at Teiid - JBoss Issue Tracker

[tamarm]

Sure, I will add it.

My question is not only for the actuator.

For example I want to add rest controller in my microservice which is not related to OData.

I want that this rest controller path will be <my-server-url>/api/<rest-controller-path>, and the OData request's path will be <my-server-url>/api/odata.

I saw that Olingo has a support for that ("org.apache.olingo.odata2.path.split" property).

(didn't find any documentation for that "split" for OData version 4)

https://olingo.apache.org/doc/odata2/tutorials/Olingo_Tutorial_Advanced_Service_Resolution.html 

Does Teiid have support for that?

We do not support "split" property, but I am sure Spring Boot will allow you to define two different contexts in a single app, why not use that? You can place odata impl in something like /odata, and your's in /api. If that needs any code changes I can help with that.

Tamar,

I did find an issue when a separate context being used for odata. I fixed that one for 1.0.2 release. Using this version you can define "server.context-path=/odata" property in the application.properties and have different odata endpoint. Then you can add the actuator spring boot starter for health stuff which will be at root.

I need to look into your /api endpoint next. If you want suggest code enhancements you are welcome, go ahead submit me patch and I will take look.

If you want to enable Actuator and also use root it is possible with Spring to open this on another port. See example here  https://www.baeldung.com/spring-boot-actuators  in Further Customization section.

Looked into this little bit today, I did not find any material that can allow two different contexts from single Spring Boot app, so that means I need to implement something like "split" functionality you mentioned before into Teiid. Go ahead and submit JIRA I can such functionality easily.

Hi Ramesh,

I created request in JIRA:

[TEIID-5614] Teiid Spring Boot - Enable Spring Actuator and non OData requests - JBoss Issue Tracker

Thanks!

Actually I used another port in order to resolve this issue, but separating management and application ports is not best practice. I prefer to check "health" on the same port as my app requests.

Here is my configuration that resolved the issue:

server:
  port: 8014
  context-path: /api/odata

management:
  port: 8015
  context-path: /api
