使用用户托管标识从Azure函数发送Event Grid事件遇类找不到异常

尝试使用UserManagedIdentity Credential向Azure EventGrid发送数据时，抛出ClassNotFoundException: com.azure.core.util.tracing.TracerProvider异常。

相关代码 #

import com.azure.identity.ManagedIdentityCredentialBuilder;
import com.azure.messaging.eventgrid.EventGridEvent;
import com.azure.messaging.eventgrid.EventGridPublisherClient;
import com.azure.messaging.eventgrid.EventGridPublisherClientBuilder;
import com.azure.core.credential.TokenCredential;

TokenCredential managedIdentityCredentialUserAssigned = new ManagedIdentityCredentialBuilder().clientId(System.getenv("MANAGED_IDENTITY_CLIENT_ID")).build();
EventGridPublisherClient<EventGridEvent> eventGridEventClient = new EventGridPublisherClientBuilder()
     .endpoint(System.getenv("EVENTGRID_SYNC_TOPIC_ENDPOINT")).credential(managedIdentityCredentialUserAssigned).buildEventGridEventPublisherClient();

依赖配置（pom.xml） #

<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-messaging-eventgrid</artifactId>
    <version>4.18.0</version>
</dependency>
<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-identity</artifactId>
    <version>1.7.3</version>
</dependency>
<dependency>
    <groupId>com.microsoft.azure</groupId>
    <artifactId>azure-eventgrid</artifactId>
    <version>1.1.0</version>
</dependency>
<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-core</artifactId>
    <version>1.35.0</version>
</dependency>

环境信息 #

• Spring Boot版本：2.7.8
• Java版本：11

解决方案 #

• 移除冲突的旧版EventGrid依赖：com.microsoft.azure:azure-eventgrid:1.1.0是Azure EventGrid的旧版SDK，和新版com.azure:azure-messaging-eventgrid存在依赖冲突，直接删除该依赖。
• 修正azure-core版本不匹配问题：azure-messaging-eventgrid:4.18.0要求的azure-core最低版本为1.47.0，当前手动指定的1.35.0版本过低。可以选择：
  1. 删除手动指定的azure-core依赖，让Maven自动根据azure-messaging-eventgrid的依赖关系引入正确版本；
  2. 手动将azure-core版本升级到1.47.0或更高（建议使用与azure-messaging-eventgrid兼容的最新稳定版）。
• 可选：统一Azure SDK版本：使用Azure BOM（Bill of Materials）统一管理所有Azure SDK依赖的版本，避免版本不匹配问题，在pom.xml中添加：

  <dependencyManagement>
      <dependencies>
          <dependency>
              <groupId>com.azure</groupId>
              <artifactId>azure-sdk-bom</artifactId>
              <version>2024.0.0</version>
              <type>pom</type>
              <scope>import</scope>
          </dependency>
      </dependencies>
  </dependencyManagement>
  

  添加后无需给单个Azure SDK依赖指定版本，BOM会自动引入兼容版本。
