Java 使用Spring Boot的Microsoft Graph api邮件服务

我在Spring Boot应用程序中使用Microsoft Graph api收发邮件

我使用了graph api的依赖项，比如

         <dependency>
             <groupId>com.microsoft.graph</groupId>
             <artifactId>microsoft-graph</artifactId>
             <version>3.5.0</version>
         </dependency>
         <dependency>
        <!-- This dependency is only needed if you are using the TokenCrendentialAuthProvider -->
        <groupId>com.azure</groupId>
        <artifactId>azure-identity</artifactId>
        <version>1.2.5</version>
    </dependency>

在处输入代码时出错

ClientSecretCredential clientSecretCredential = new ClientSecretCredentialBuilder()
            .clientId(CLIENT_ID)
            .clientSecret(CLIENT_SECRET).tenantId(TENANT_GUID).build();
    
    TokenCredentialAuthProvider tokenCredentialAuthProvider = new TokenCredentialAuthProvider(SCOPES, clientSecretCredential);


    GraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider( tokenCredentialAuthProvider ).buildClient();
    

    MessageCollectionPage messagesPage = graphClient.me().messages()
            .buildRequest()
            .select("Sender,Subject")
            .top(10)
            .get();

我在代码中遇到了这样的错误

 (DirectJDKLog.java:175) - Servlet.service() for servlet [dispatcherServlet] in context with path [/ldesk] threw exception [Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class com.azure.identity.implementation.IdentityClient] with root cause

如果使用microsoft graph 3.4.0，则不能使用microsoft graph auth创建IAAuthenticationProvider对象

:

:

首先，在Pom.xml中添加

azureidentity

ClientSecretCredential clientSecretCredential = new ClientSecretCredentialBuilder()
        .clientId(clientId)
        .clientSecret(clientSecret)
        .tenantId(tenant)
        .build();

TokenCredentialAuthProvider tokenCredentialAuthProvider = new TokenCredentialAuthProvider(scopes, clientSecretCredential);

GraphServiceClient graphClient =
  GraphServiceClient
    .builder()
    .authenticationProvider(tokenCredentialAuthProvider)
    .buildClient();

User me = graphClient.users(user_id).buildRequest().get();

如果我的回答有帮助，请接受我的回答，谢谢。IGraphServiceClient在microsoft graph版本3.4中不起作用。microsoft-graph-auth不支持新版本。请看我的更新。嗨，Pamela Peng，你能给我分享Git中最新版本的工作示例吗。我已经分享了获取graphClient的代码，doc。也许您可以参考本教程：。

ClientCredentialProvider authProvider = new ClientCredentialProvider(CLIENT_ID, SCOPES, CLIENT_SECRET, TENANT_GUID, NATIONAL_CLOUD);

IGraphServiceClient graphClient = GraphServiceClient
                .builder()
                .authenticationProvider(authProvider)
                .buildClient();

User user = graphClient.users(user_id).buildRequest().get();

ClientSecretCredential clientSecretCredential = new ClientSecretCredentialBuilder()
        .clientId(clientId)
        .clientSecret(clientSecret)
        .tenantId(tenant)
        .build();

TokenCredentialAuthProvider tokenCredentialAuthProvider = new TokenCredentialAuthProvider(scopes, clientSecretCredential);

GraphServiceClient graphClient =
  GraphServiceClient
    .builder()
    .authenticationProvider(tokenCredentialAuthProvider)
    .buildClient();

User me = graphClient.users(user_id).buildRequest().get();
