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 JSON
		if (isValidJson(jsonStr)) {
			// 解析 JSON 字符串为 JsonArray
			Gson 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 JSON
			System.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

package org.springblade.common.utils;

import com.tencentcloudapi.common.Credential;
import com.tencentcloudapi.common.exception.TencentCloudSDKException;
import com.tencentcloudapi.tmt.v20180321.TmtClient;
import com.tencentcloudapi.tmt.v20180321.models.TextTranslateRequest;
import com.tencentcloudapi.tmt.v20180321.models.TextTranslateResponse;
import org.springblade.core.tool.utils.Func;

import java.lang.reflect.Field;

/**
 * @project
 * @Classname
 * @Description
 * @Author:
 * @CreateTime:
 */
public class TencentTranslationUtil {

	private final static String secretId = "自己的";
	private final static String secretKey = "自己的";
	private final static String params = "isMenu,type,icon";


	private final TmtClient client;

	/**
	 * 翻译
	 *
	 * @param text       需要翻译的文本
	 * @param sourceLang 来源语言
	 * @param targetLang 目标语言
	 * @return
	 */
	public static String getText(String text, String sourceLang, String targetLang) {
		TencentTranslationUtil translationClient = new TencentTranslationUtil(secretId, secretKey);
		if (Func.isEmpty(text.trim())) {
			return text;
		}
		try {
			return translationClient.translateText(text, sourceLang, targetLang);
		} catch (TencentCloudSDKException e) {
			System.err.println("腾讯翻译错误 = " + e.getMessage());
		}
		return "";
	}

	/**
	 * secretId，secretKey id和密钥
	 */
	public TencentTranslationUtil(String secretId, String secretKey) {
		Credential cred = new Credential(secretId, secretKey);
		client = new TmtClient(cred, "ap-beijing");
	}

	/**
	 * secretId，secretKey id和密钥
	 * region 地域
	 */
	public TencentTranslationUtil(String secretId, String secretKey, String region) {
		Credential cred = new Credential(secretId, secretKey);
		client = new TmtClient(cred, region);
	}

	/**
	 * text 需要翻译的文本
	 * sourceLang 翻译文本的语种
	 * targetLang 目标语种
	 */
	public String translateText(String text, String sourceLang, String targetLang) throws TencentCloudSDKException {
		TextTranslateRequest req = new TextTranslateRequest();
		req.setSourceText(text);
		req.setSource(sourceLang);
		req.setTarget(targetLang);
		req.setProjectId(0L);
		TextTranslateResponse resp = client.TextTranslate(req);
		return resp.getTargetText();
	}

	/**
	 * 翻译对象每个的字段并重新给对象赋值
	 * @param obj
	 * @param sourceLang
	 * @param targetLang
	 */
	public static void translateFields(Object obj, String sourceLang, String targetLang) {
		if (!sourceLang.equals(targetLang)) {
			Class<?> clazz = obj.getClass();
			Field[] fields = clazz.getDeclaredFields();
			try {
				for (Field field : fields) {
					field.setAccessible(true); // 允许访问私有字段
					Object value = field.get(obj);
					//值不为空，且是字符串，不包含透明度，值非纯数字
					if (Func.isNotEmpty(value) && value instanceof String
						&& !((String) value).contains("div") && !((String) value).contains("opacity") && !isNumeric(((String) value))) {
						if (!params.contains(field.getName())) {
							Thread.sleep(150);
							String text = TencentTranslationUtil.getText((String) value, sourceLang, targetLang);
							if (Func.isNotEmpty(text)) {
								field.set(obj, text); // 重新赋值翻译后的文本
							} else {
								field.set(obj, Func.toStr(value)+"(翻译失败)"); // 重新赋值翻译后的文本
							}
						}
					}
				}
			} catch (Exception e) {
			}
		}
	}

	public static void main(String[] args) {
//		System.out.println(getText("{\"opacity\":1,\"x\":\"67.5px\",\"y\":\"53px\",\"rotate\":0}","en","zh-TW"));
//		System.out.println("args = " + isNumeric("1s"));
		if(!isNumeric("1")){
			System.out.println("翻译");
		}
	}

	/**
	 * 判断字符串是否是纯数字
	 * @param str
	 * @return
	 */
	public static boolean isNumeric(String str) {
		return str.matches("-?\\d+(\\.\\d+)?");
	}
}
