本文主要研究一下Spring AI Alibaba的FeiShuDocumentReader
FeiShuDocumentReader
community/document-readers/spring-ai-alibaba-starter-document-reader-larksuite/src/main/java/com/alibaba/cloud/ai/reader/feishu/FeiShuDocumentReader.java

FeiShuDocumentReader构造器依赖FeiShuResource，其get方法通过loadDocuments将feiShuResource解析为documents，它通过
com.lark.oapi.Client根据userAccessToken或tenantAccessToken去读取文档
FeiShuResource
community/document-readers/spring-ai-alibaba-starter-document-reader-larksuite/src/main/java/com/alibaba/cloud/ai/reader/feishu/FeiShuResource.java
public class FeiShuResource implements Resource {public static final String SOURCE = "source";public static final String FEISHU_PROPERTIES_PREFIX = "spring.ai.alibaba.plugin.feishu";private final String appId;private final String appSecret;//......
}
FeiShuResource定义了appId、appSecret属性
示例
@EnabledIfEnvironmentVariable(named = "FEISHU_APP_ID", matches = ".+")
@EnabledIfEnvironmentVariable(named = "FEISHU_APP_SECRET", matches = ".+")
public class FeiShuDocumentReaderTest {private static final Logger log = LoggerFactory.getLogger(FeiShuDocumentReaderTest.class);// Get configuration from environment variablesprivate static final String FEISHU_APP_ID = System.getenv("FEISHU_APP_ID");private static final String FEISHU_APP_SECRET = System.getenv("FEISHU_APP_SECRET");// Optional user token and document ID from environment variablesprivate static final String FEISHU_USER_TOKEN = System.getenv("FEISHU_USER_TOKEN");private static final String FEISHU_DOCUMENT_ID = System.getenv("FEISHU_DOCUMENT_ID");private FeiShuDocumentReader feiShuDocumentReader;private FeiShuResource feiShuResource;static {if (FEISHU_APP_ID == null || FEISHU_APP_SECRET == null) {System.out.println("FEISHU_APP_ID or FEISHU_APP_SECRET environment variable is not set.

小结
spring-ai-alibaba-starter-document-reader-larksuite提供了FeiShuDocumentReader用于根据userAccessToken或tenantAccessToken读取飞书文档列表或者指定documentId的文档内容。
