구현 가이드

We’ll break down the process into three main sections: Document Loading and Password Handling, Document Editing Options, and Content Editing and Saving. Let’s explore each feature step‑by‑step.

기능 1: 문서 로드 및 비밀번호 처리

Overview: This section demonstrates how to load password protected doc using GroupDocs.Editor for Java. It’s essential when handling sensitive documents that require access control.

단계 1: 문서 경로 정의

First, specify the location of your Word document:

String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.docx";

단계 2: InputStream 생성

Next, initialize a file input stream for reading the document:

InputStream fs = new FileInputStream(inputFilePath);

단계 3: 비밀번호 보호 로드 옵션 설정

To handle documents that are password‑protected, configure the load options:

WordProcessingLoadOptions loadOptions = new WordProcessingLoadOptions();
loadOptions.setPassword("some_password_to_open_a_document");

단계 4: Editor를 사용해 문서 로드

Finally, use the Editor class to open and work with the document:

Editor editor = new Editor(fs, loadOptions);

기능 2: 문서 편집 옵션

Overview: Configuring editing options such as font extraction and language information can enhance document processing capabilities.

단계 1: 편집 옵션 생성

Begin by initializing your editing options object:

WordProcessingEditOptions editOptions = new WordProcessingEditOptions();

단계 2: 폰트 추출 활성화

To ensure embedded fonts are used, configure the following option:

editOptions.setFontExtraction(FontExtractionOptions.ExtractEmbeddedWithoutSystem);

단계 3: 언어 정보 추출

Enabling language information can be useful for multilingual document processing:

editOptions.setEnableLanguageInformation(true);

단계 4: 페이지 매김 모드 활성화

For easier editing, especially with long documents, switch on pagination mode:

editOptions.setEnablePagination(true);

기능 3: 콘텐츠 편집 및 문서 저장

Overview: This section shows how to modify document content and save it with specific configurations such as format and password protection.

단계 1: 원본 콘텐츠 추출

Start by extracting the original content and resources:

String originalContent = beforeEdit.getContent();
List<IHtmlResource> allResources = beforeEdit.getAllResources();

단계 2: 문서 콘텐츠 수정

Change the document’s text as needed. Here, we replace “document” with “edited document”:

String editedContent = originalContent.replace("document", "edited document");
EditableDocument afterEdit = EditableDocument.fromMarkup(editedContent, allResources);

단계 3: 저장 옵션 설정

Configure how the document should be saved, including format and password:

WordProcessingFormats docmFormat = WordProcessingFormats.Docm;
WordProcessingSaveOptions saveOptions = new WordProcessingSaveOptions(docmFormat);
saveOptions.setPassword("password");
saveOptions.setEnablePagination(true);
saveOptions.setLocale(Locale.US);
saveOptions.setOptimizeMemoryUsage(true);
saveOptions.setProtection(new WordProcessingProtection(WordProcessingProtectionType.ReadOnly, "write_password"));

단계 4: 편집된 문서 저장

Finally, write the edited document to an output file:

String outputPath = "YOUR_OUTPUT_DIRECTORY/edited_output.docm";
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
editor.save(afterEdit, outputStream, saveOptions);
try (FileOutputStream outputFile = new FileOutputStream(outputPath)) {
    outputStream.writeTo(outputFile);
}
