[BUG] azure-spring-boot-starter-keyvault-secrets hangs with spring-boot 2.4.4

[Tcharl]

Describe the bug Using the latest and greatest azure-spring-boot-starter-keyvault-secrets indefinitely hangs on start

Exception or Stack Trace No exception at all, just stucked

To Reproduce Steps to reproduce the behavior:

I generated an app with the latest jhipster, then added these dependencies:

<dependency>
            <groupId>com.azure.spring</groupId>
            <artifactId>azure-spring-boot-starter-keyvault-secrets</artifactId>
            <version>3.3.0</version>
        </dependency>
        <dependency><!-- Mandatory because spring uses databind 2.11.4 which is incompatible with keyvault-->
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.12.1</version>
        </dependency>

}

}

service * with serviceImpl

FYI, it's on spring boot 2.4.4

[yiliuTo]

Hi @Tcharl , I reproduced your issue with our sample by specifying spring boot as 2.4.4 and jackson-databind as 2.12.1. And the bug is caused due to that spring boot 2.4.4 only supports jackson 2.11.1 while our starter supports both 2.12.1 and 2.11.1 actually, which could be refered to https://github.com/Azure/azure-sdk-for-java/pull/19967/ and https://github.com/Azure/azure-sdk-for-java/pull/19918. So in our sample, it could work with spring boot 2.4.4 and jackson-databind 2.11.1. So you could try with removing below version in your pom.xml

        <dependency><!-- Mandatory because spring uses databind 2.11.4 which is incompatible with keyvault-->
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.12.1</version>
        </dependency>

If it still hangs after modifying version of jackson-databind, cloud you provide a project with our sample that could reproduce your issue?

Not possible: azure vault is using a method that do not exists in 2.11.x...

[yiliuTo]

Hi @Tcharl , I ignored that the mentioned commits to support both 2.12.x and 2.11.x are not in our starter 3.3.0. So I think you could use the key vault starter 3.4.0 and remove dependency of jackson-databind:2.12.1, or use starter 3.3.0 together with the following dependency:

<dependency>
        <groupId>com.azure</groupId>
        <artifactId>azure-core</artifactId>
        <version>1.14.1</version>
      </dependency>
