1. 在AEM中安装DocuSign的API依赖项。
2. 创建与DocuSign API和AEM集成的API应用程序。
3. 使用Java编写自定义代码，实现AEM和DocuSign集成，并确保在AEM中可以通过API访问DocuSign电子签名。 下面是一个基本的Java代码示例，演示如何使用DocuSign API来创建一个新文档并将其发送给已指定的收件人进行签署：

// Create a new envelope with a document
EnvelopeDefinition envDef = new EnvelopeDefinition();
envDef.setEmailSubject("Please sign this document");
envDef.setEmailBlurb("This document needs your signature");
    
// Read files from a local directory
byte[] fileBytes = Files.readAllBytes(Paths.get("/path/to/document.pdf"));
Bidning pdfDoc = new Document();
pdfDoc.setDocumentBase64(Base64.getEncoder().encodeToString(fileBytes));
pdfDoc.setName("Document.pdf");
pdfDoc.setFileExtension("pdf");
    
// Attach document and add recipient
Document[] docs = new Document[] { pdfDoc };
envDef.setDocuments(Arrays.asList(docs));
Signer signer = new Signer();
signer.setEmail("recipient@example.com");
signer.setName("Recipient");
signer.setRecipientId("1");
signer.setTabs(getTabs());
signer.setRoutingOrder("1");
    
// Add recipient and send envelope
envDef.setRecipients(new Recipients());
envDef.getRecipients().setSigners(Arrays.asList(signer));
envDef.setStatus("sent");
    
try {
    ApiClient apiClient = new ApiClient();
    apiClient.setBasePath("https://demo.docusign.net/restapi");
    
    // Authenticate with DocuSign
    DocuSignToken token = apiClient.requestJWTUserToken(CLIENT_ID, USER_GUID, "signature");
    apiClient.setAccessToken(token.getAccessToken());
    
    // Create envelope and send
    EnvelopesApi envelopesApi = new EnvelopesApi(apiClient);
    EnvelopeSummary envelopeSummary = envelopesApi.createEnvelope(ACCOUNT_ID, envDef);
} catch (ApiException ex) {
    // Handle exception
}
