Problem when creating KeyClient with Azure SDK for Java

Question

I'm trying to create a KeyClient object in my code so I can create keys in azure key vault. But my object keeps getting error on service and I could not solve it until now. This is my code:

@Override
    public void generateProductAuthKeyPair(Long channelId) {
        try {
            KeyClient keyClient = new KeyClientBuilder()
                    .vaultUrl(keyVaultUrl)
                    .credential(new DefaultAzureCredentialBuilder().build())
                    .buildClient();

            String keyName = "UseAuthKeyChannel" + channelId.toString();
            CreateEcKeyOptions keyOptions = new CreateEcKeyOptions(keyName);
            keyOptions.setCurveName(KeyCurveName.P_256);

            KeyVaultKey ecKey = keyClient.createEcKey(new CreateEcKeyOptions(keyName)
                    .setCurveName(KeyCurveName.P_256)
                    .setExpiresOn(OffsetDateTime.now().plusYears(1)));
            System.out.printf("Key created with name \"%s\" and id %s%n", ecKey.getName(), ecKey.getId());

            Channel channel = channelRepository.getChannelById(channelId);


        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Everytime I create the keyClient, it's created with an error inside service, as you can see in the image:

It seems to be missing anotations inside service, but it is an internal class. I'm using latest versions of azure sdk. Here follow my dependencies inside pom.xml:

The keyClient is created but I can't perform any functions with it, cause the service throws exception. Does someone knows how to fix this problem?

I made some changes to your code and was able to create a key in the Azure Key Vault.

Code :

KeyVaultService.java :

import com.azure.identity.DefaultAzureCredentialBuilder;
import com.azure.security.keyvault.keys.KeyClient;
import com.azure.security.keyvault.keys.KeyClientBuilder;
import com.azure.security.keyvault.keys.models.CreateEcKeyOptions;
import com.azure.security.keyvault.keys.models.KeyCurveName;
import com.azure.security.keyvault.keys.models.KeyVaultKey;
import org.springframework.stereotype.Service;

import java.time.OffsetDateTime;

@Service
public class KeyVaultService {

    private static final String keyVaultUrl = "https://<keyvault_name>.vault.azure.net/";

    public void generateProductAuthKeyPair(Long channelId) {
        try {
            KeyClient keyClient = new KeyClientBuilder()
                    .vaultUrl(keyVaultUrl)
                    .credential(new DefaultAzureCredentialBuilder().build())
                    .buildClient();

            String keyName = "<key_name>" + channelId.toString();
            CreateEcKeyOptions keyOptions = new CreateEcKeyOptions(keyName)
                    .setCurveName(KeyCurveName.P_256)
                    .setExpiresOn(OffsetDateTime.now().plusYears(1));

            KeyVaultKey ecKey = keyClient.createEcKey(keyOptions);
            System.out.printf("Key created with name \"%s\" and id %s%n", ecKey.getName(), ecKey.getId());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

KeyController.java :

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/api/keys")
public class KeyController {

    private final KeyVaultService keyVaultService;

    @Autowired
    public KeyController(KeyVaultService keyVaultService) {
        this.keyVaultService = keyVaultService;
    }

    @GetMapping("/generate")
    public String generateProductAuthKeyPair() {
        keyVaultService.generateProductAuthKeyPair(123L);
        return "Key generation initiated. Check logs for details.";
    }
}

pom.xml :

<dependencies>
    <dependency>
        <groupId>com.azure</groupId>
        <artifactId>azure-security-keyvault-keys</artifactId>
        <version>4.7.3</version>
    </dependency>
    <dependency>
        <groupId>com.azure</groupId>
        <artifactId>azure-identity</artifactId>
        <version>1.11.1</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>com.azure</groupId>
        <artifactId>azure-core</artifactId>
        <version>1.45.1</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
     </dependency>
</dependencies>

Output :

The code ran successfully and created a key in Azure Key Vault.

http://localhost:8080/api/keys/generate

enter image description here

Key created with name "kamalikey123" and id
https://kamxvault.vault.azure.net/keys/kamalikey1123/9fd9fa14xxxxxxx
