Java集成Onlyoffice的示例代碼及場景分析
更新時間：2025年05月27日 11:30:34 作者：想要變瘦的小碼頭
這篇文章主要介紹了Java集成Onlyoffice的示例代碼及場景分析,本文給大家介紹的非常詳細,對大家的學(xué)習(xí)或工作具有一定的參考借鑒價值,需要的朋友參考下吧
需求場景：實現(xiàn)文檔的在線編輯，團隊協(xié)作
總結(jié)：兩個接口 + 前端頁面 + 配置項
接口1：一個接口，將onlyoffice前端需要的配置項返回給前端（文檔地址、是否編輯模式...）
前端：接受配置項，集成onlyoffice的js文件，展示文檔
接口2：一個回調(diào)接口，用于onlyoffice前端的文件保存后的調(diào)用方法
一些配置項：application 里面配置 服務(wù)器的地址，token 等 ，maven 引入依賴。
文章結(jié)尾提供官方示例代碼：
注意：
1、docs-integration-sdk 2024年12月，國內(nèi)騰訊的中央倉庫下不了，我不想換鏡像，就注釋掉，用的離線包。
2、加了一個pom 的依賴，不加啟動報錯
<dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.13</version> </dependency>
接口1：文檔地址必須可以讓onlyofficeu所在的服務(wù)器可以訪問到，可以是本地磁盤的映射，可以是 MINIO。文檔應(yīng)當(dāng)還有一個唯一的Key；
public String index(@RequestParam("fileName") final String fileName,
@RequestParam(value = "action", required = false) final String actionParam,
@RequestParam(value = "type", required = false) final String typeParam,
@RequestParam(value = "actionLink", required = false) final String actionLink,
@CookieValue(value = "uid") final String uid,
@CookieValue(value = "ulang") final String lang,
final Model model) throws JsonProcessingException {
Action action = null;
Type type = Type.DESKTOP;
Locale locale = new Locale("en");
if (actionParam != null) {
action = Action.valueOf(actionParam);
}
if (typeParam != null) {
type = Type.valueOf(typeParam.toUpperCase());
}
List<String> langsAndKeys = Arrays.asList(langs.split("\\|"));
for (String langAndKey : langsAndKeys) {
String[] couple = langAndKey.split(":");
if (couple[0].equals(lang)) {
String[] langAndCountry = couple[0].split("-");
locale = new Locale(langAndCountry[0], langAndCountry.length > 1 ? langAndCountry[1] : "");
}
}
Optional<User> optionalUser = userService.findUserById(Integer.parseInt(uid));
// if the user is not present, return the ONLYOFFICE start page
if (!optionalUser.isPresent()) {
return "index.html";
}
Config config = configService.createConfig(
fileName,
action,
type
);
JSONObject actionData = null;
if (actionLink != null && !actionLink.isEmpty()) {
actionData = new JSONObject(actionLink);
}
config.getEditorConfig().setActionLink(actionData);
config.getEditorConfig().setLang(locale.toLanguageTag());
model.addAttribute("model", config);
// create the document service api URL and add it to the model
model.addAttribute("docserviceApiUrl", urlManager.getDocumentServerApiUrl());
// get an image and add it to the model
model.addAttribute("dataInsertImage", getInsertImage());
// get a document for comparison and add it to the model
model.addAttribute("dataDocument", getCompareFile());
// get recipients data for mail merging and add it to the model
model.addAttribute("dataSpreadsheet", getSpreadsheet());
// get user data for mentions and add it to the model
model.addAttribute("usersForMentions", getUserMentions(uid));
model.addAttribute("usersInfo", getUsersInfo(uid));
// get user data for protect and add it to the model
model.addAttribute("usersForProtect", getUserProtect(uid));
return "editor.html";
}接口2：回調(diào)保存，其中的 {\"error\":\"0\"} 是告訴onlyOffice回調(diào)接口是沒問題的，這樣就可以在線編輯文檔了，否則的話會彈出窗口說明。
public String track(final HttpServletRequest request, // track file changes
@RequestParam("fileName") final String fileName,
@RequestParam("userAddress") final String userAddress,
@RequestBody final Callback body) {
Callback callback;
try {
String bodyString = objectMapper
.writeValueAsString(body); // write the request body to the object mapper as a string
if (bodyString.isEmpty()) { // if the request body is empty, an error occurs
throw new RuntimeException("{\"error\":1,\"message\":\"Request payload is empty\"}");
}
String authorizationHeader = request.getHeader(settingsManager.getSecurityHeader());
callback = callbackService.verifyCallback(body, authorizationHeader);
callbackService.processCallback(callback, fileName);
} catch (Exception e) {
String message = e.getMessage();
if (!message.contains("\"error\":1")) {
e.printStackTrace();
}
return message;
}
return "{\"error\":\"0\"}";
}前端展示
