Java 使用腾讯翻译 API 实现含 HTML 标签文本，json值，精准翻译工具

注意：需搭配标题二的腾讯翻译工具使用

一-1、翻译标签文本工具

package org.springblade.common.utils;import java.util.ArrayList;
import java.util.List;
import java.util.regex.Matcher;
import java.util.regex.Pattern;public class TencentTranslationForHTML {public static void main(String[] args) {String htmlContent = "<div style=\"text-align:center\"><img src=\"http://192.168.0.137:8999/machine/upload/image/20250208/32551087576762.jpg\" alt=\"图片 alt\" width=\"350\" height=\"auto\" data-align=\"center\"></div><p style=\"text-align: center\">下料工序后的加工件</p>";try {String translatedHtml = translateHTML(htmlContent);System.out.println(translatedHtml);} catch (Exception e) {e.printStackTrace();}}public static String translateHTML(String html) throws com.tencentcloudapi.common.exception.TencentCloudSDKException {// 匹配 HTML 标签Pattern tagPattern = Pattern.compile("<[^>]+>");Matcher tagMatcher = tagPattern.matcher(html);// 存储标签位置和内容List<int[]> tagPositions = new ArrayList<>();while (tagMatcher.find()) {tagPositions.add(new int[]{tagMatcher.start(), tagMatcher.end()});}// 提取文本内容进行翻译List<String> textParts = new ArrayList<>();int lastEnd = 0;for (int[] position : tagPositions) {String textPart = html.substring(lastEnd, position[0]);if (!textPart.isEmpty()) {textParts.add(textPart);}lastEnd = position[1];}String remainingText = html.substring(lastEnd);if (!remainingText.isEmpty()) {textParts.add(remainingText);}// 调用腾讯翻译 API 翻译文本List<String> translatedParts = new ArrayList<>();for (String text : textParts) {
//            String translated = translateText(text);String translated = TencentTranslationUtil.getText(text,"zh","en");translatedParts.add(translated);}// 重新组合翻译后的文本和 HTML 标签StringBuilder result = new StringBuilder();int textPartIndex = 0;lastEnd = 0;for (int[] position : tagPositions) {int start = position[0];int end = position[1];if (start > lastEnd) {result.append(translatedParts.get(textPartIndex++));}result.append(html, start, end);lastEnd = end;}if (lastEnd < html.length()) {result.append(translatedParts.get(textPartIndex));}return result.toString();}}

一-2、翻译json工具

package org.springblade.common.utils;import com.google.gson.Gson;
import com.google.gson.JsonArray;
import com.google.gson.JsonElement;
import com.google.gson.JsonObject;import java.util.ArrayList;
import java.util.List;public class TencentTranslationForJson {public static void main(String[] args) {String jsonStr = "[{\"col1\":\"设备名称及数量\",\"col2\":\"铝切机、切管机\",\"$cellEdit\":false,\"$index\":0},{\"col1\":\"最大日产量\",\"col2\":\"10000 件\",\"$cellEdit\":false,\"$index\":1},{\"col1\":\"工人数量\",\"col2\":\"5 人\",\"$cellEdit\":false,\"$index\":2}]";extracted(jsonStr, "en", "zh");}public static void extracted(String jsonStr, String sourceLang, String targetLang) {// 判断是否为有效的 JSONif (isValidJson(jsonStr)) {// 解析 JSON 字符串为 JsonArrayGson gson = new Gson();JsonArray jsonArray = gson.fromJson(jsonStr, JsonArray.class);// 遍历 JSON 数组，提取需要翻译的文本List<String> textsToTranslate = new ArrayList<>();for (JsonElement element : jsonArray) {JsonObject obj = element.getAsJsonObject();for (String key : obj.keySet()) {if (obj.get(key).isJsonPrimitive() && obj.get(key).getAsJsonPrimitive().isString()) {textsToTranslate.add(obj.get(key).getAsString());}}}// 调用腾讯翻译 API 进行翻译List<String> translatedTexts = translateTexts(textsToTranslate, sourceLang, targetLang);// 将翻译结果回填到 JSON 中int index = 0;for (JsonElement element : jsonArray) {JsonObject obj = element.getAsJsonObject();for (String key : obj.keySet()) {if (obj.get(key).isJsonPrimitive() && obj.get(key).getAsJsonPrimitive().isString()) {obj.addProperty(key, translatedTexts.get(index));index++;}}}// 输出翻译后的 JSONSystem.out.println(gson.toJson(jsonArray));} else {System.out.println("输入的字符串不是有效的 JSON，不进行翻译。");}}private static boolean isValidJson(String jsonStr) {jsonStr = jsonStr.trim();if (jsonStr.isEmpty()) {return false;}// 判断是否以 '{' 或 '[' 开头，以 '}' 或 ']' 结尾if ((jsonStr.startsWith("{") && jsonStr.endsWith("}")) || (jsonStr.startsWith("[") && jsonStr.endsWith("]"))) {try {int depth = 0;boolean inString = false;for (int i = 0; i < jsonStr.length(); i++) {char c = jsonStr.charAt(i);if (inString) {if (c == '\\') {i++; // 跳过转义字符后的字符} else if (c == '"') {inString = false;}} else {if (c == '"') {inString = true;} else if (c == '{' || c == '[') {depth++;} else if (c == '}' || c == ']') {depth--;if (depth < 0) {return false; // 括号不匹配}}}}return depth == 0 && !inString; // 括号完全匹配且不在字符串中结束} catch (Exception e) {return false;}}return false;}private static List<String> translateTexts(List<String> texts, String sourceLang, String targetLang) {List<String> translatedTexts = new ArrayList<>();for (String text : texts) {String translatedText = TencentTranslationUtil.getText(text, sourceLang, targetLang);translatedTexts.add(translatedText);}return translatedTexts;}
}

二、腾讯翻译api调用

}
