I updated the application dependencies from

Old versions:  
Springboot: 2.7.3  
Temporal & temporal-spring-boot-autoconfigure-alpha: 1.16.0

New versions:  
Springboot: 3.0.6  
Temporal & temporal-spring-boot-autoconfigure-alpha: 1.19.1

The temporal worker poller seems to be not starting after the update but it works fine with the older versions. We are able to create workflows but it shows as no workers found.

**Old:**

**Application Property yaml**

```auto
  spring:
    temporal:
      connection:
        target: ${TEMPORAL_HOST}:${TEMPORAL_PORT}
        target.namespace: ${TEMPORAL_NAMESPACE}
      workers:
        - task-queue: GENERIC_WORKFLOW_QUEUE
      workflow-cache:
        max-instances: 10
        max-threads: 10
      workersAutoDiscovery:
        packages: com.endowus.workflow.engine.hk
      timeouts:
        activityStartToCloseTimeout: ${ACTIVITY_START_TO_CLOSE_TIMEOUT}
        workflowTimeout: ${WORKFLOW_TIMEOUT}

```

Please help out on how I could resolve this. Thanks in advance!

@Anjula_Paulus

I have something working using the same versions, and I can see the pollers.

```auto
2023-05-25 13:01:04.961 INFO [temporal-demo,,] 26333 --- [main] io.temporal.internal.worker.Poller : start: Poller{name=Workflow Poller taskQueue="DemoTaskQueue", namespace="default", identity=26333@Antonio-Perezs-MacBook-Pro.local}

```

You can find the repo here [GitHub - antmendoza/temporal\_spring-boot-demo at community\_8340](https://github.com/antmendoza/temporal_spring-boot-demo/tree/community_8340)

If you want to share something to reproduce it I can take a look

Thanks,

@antonio.perez Does this warn logs mean something?

@Anjula_Paulus

you can add the log level to your `application.yml` for `io.temporal`

```auto
logging:
  level:
    io.temporal: debug

```

> Does this warn logs mean something?

Looks like a spring issue [Unnecessary parameter name introspection for constructor-arg resolution (leading to LocalVariableTableParameterNameDiscoverer warnings) · Issue #29612 · spring-projects/spring-framework · GitHub](https://github.com/spring-projects/spring-framework/issues/29612)

@Anjula_Paulus were you able to solve this ?

@antonio.perez i am seeing the exact same behaviour .Could you checkout this [demo repo](https://github.com/vijaysenthil/temporal-demo) to see what the issue might be ? [GitHub - vijaysenthil/temporal-demo](https://github.com/vijaysenthil/temporal-demo)

as a workaround i was able to explicitly register the worker, the config based / auto discovery is the part that is not working

For me this was fixed by explicitly starting the Spring application context:

`ConfigurableApplicationContext applicationContext = SpringApplication.run(DemoApplication.class, args); applicationContext.start();`

See this comment from `RootNamespaceAutoConfiguration`:

```auto
// It needs to listed on ContextStartedEvent, not ContextRefreshedEvent.
// Using ContextRefreshedEvent will cause start of workers early, during the context
// initialization
// and potentially incorrect order of bean initialization.
// Refresh event can also be fired multiple times during the context initialization.
// For this listener to ever work, Spring context needs to be actually started.
// Note that a lot of online samples for Spring don't start the context at all:
// https://stackoverflow.com/questions/48099355/contextstartedevent-not-firing-in-custom-listener

thanks @chris I can confirm that fixed it for me too 🙏 Would be awesome if this was called out in the [temporal spring boot starter page](https://github.com/temporalio/sdk-java/tree/098504118900b2f4bc71fd52d183484b4af444fd/temporal-spring-boot-autoconfigure-alpha)

I recently upgraded to Spring boot 3.2.4 and Temporal 1.22.3. After upgrading, I see the same issue. I also have the application context started explicitly.
