我想修改docx文檔 - 通過使用java nio ZipFileSystem
更改單詞/ document.xml作爲字節數組獲得。 我有以下代碼(基於SO討論How to edit MS Word documents using Java?):從作爲字節數組獲取的docx文件中創建ZipFileSystem而不寫入文件
public static void modifyDocxContent(byte[] docx, byte[] newContent) {
try {
// Create a Word File from byte[]
File docxFile = new File("C:\\test\\simple.docx");
Path docxPath = docxFile.toPath();
Files.write(docxPath, docx);
// Create jar URI for the same Word file
URI docxUri = URI.create("jar:file:/C:/test/simple.docx");
// Create a zip FileSystem for word file and modify content in it
Map<String, String> zipProperties = new HashMap<>();
zipProperties.put("encoding", "UTF-8");
zipProperties.put("create", "false");
try (FileSystem zipFS = FileSystems.newFileSystem(docxUri, zipProperties)) {
Path documentXmlPath = zipFS.getPath("word", "document.xml");
Files.delete(documentXmlPath);
Files.write(documentXmlPath, newContent, StandardOpenOption.CREATE, StandardOpenOption.APPEND, StandardOpenOption.TRUNCATE_EXISTING, StandardOpenOption.SYNC);
}
} catch (IOException e) {
e.printStackTrace();
}
}
我想,以避免文件創建和寫入磁盤,以獲得URI需要newFileSystem
調用中使用。有沒有一種更有效的方式來獲得這樣的nio ZipFileSystem?
