思考一下日常开发中如何将 博主最帅 转为 bozhuzuishuai 或是 bzzs 等等。解析字符串？转码？这些方法都过时了。下面博主给大家推荐一个方法。让你三步完成转换。
步骤一
- 导入maven依赖
<dependency> <groupId>com.belerweb</groupId> <artifactId>pinyin4j</artifactId> <version>2.5.0</version> <scope>compile</scope> </dependency>
步骤二
- 编写工具类以及转换方法
package com.example.jinzproduct.util; import net.sourceforge.pinyin4j.PinyinHelper; import net.sourceforge.pinyin4j.format.HanyuPinyinCaseType; import net.sourceforge.pinyin4j.format.HanyuPinyinOutputFormat; import net.sourceforge.pinyin4j.format.HanyuPinyinToneType; import net.sourceforge.pinyin4j.format.HanyuPinyinVCharType; import net.sourceforge.pinyin4j.format.exception.BadHanyuPinyinOutputFormatCombination; import java.util.HashMap; import java.util.Map; import java.util.regex.Matcher; import java.util.regex.Pattern; /** * @author mengzhichao * @create 2022-11-10-10:00 */ public class ChangeChinesePinyin { public static Map<String, String> changeChinesePinyin(String chinese) throws BadHanyuPinyinOutputFormatCombination { Map<String, String> pinyin = new HashMap<String, String>(); HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat(); format.setCaseType(HanyuPinyinCaseType.LOWERCASE); format.setToneType(HanyuPinyinToneType.WITHOUT_TONE); format.setVCharType(HanyuPinyinVCharType.WITH_V); StringBuffer fullPinyin = new StringBuffer(); StringBuffer simplePinyin = new StringBuffer(); StringBuffer firstPinyin = new StringBuffer(); char[] chineseChar = chinese.toCharArray(); for (int i = 0; i < chineseChar.length; i++) { String[] str = null; try { str = PinyinHelper.toHanyuPinyinStringArray(chineseChar[i], format); } catch (BadHanyuPinyinOutputFormatCombination e) { e.printStackTrace(); } if (str != null) { if (str.length == 0) { continue; } fullPinyin = fullPinyin.append(str[0].toString()); simplePinyin = simplePinyin.append(str[0].charAt(0)); } if (str == null) { String regex = "^[0-9]*[a-zA-Z]*+$"; Pattern pattern = Pattern.compile(regex); Matcher m = pattern.matcher(String.valueOf(chineseChar[i])); if (m.find()) { fullPinyin = fullPinyin.append(chineseChar[i]); simplePinyin = simplePinyin.append(chineseChar[i]); } } } String[] name = PinyinHelper.toHanyuPinyinStringArray(chineseChar[0], format); if(name == null && fullPinyin.substring(0,1).matches("[a-zA-Z]")){ name = new String[]{fullPinyin.substring(0,1)}; }else if (name == null){ name = new String[]{"#"}; } firstPinyin = firstPinyin.append(name[0].charAt(0)); pinyin.put("fullPinyin", fullPinyin.toString()); pinyin.put("simplePinyin", simplePinyin.toString().toUpperCase()); pinyin.put("groupPinyin", firstPinyin.toString().toUpperCase()); return pinyin; } }
步骤三
- 测试看结果
public static void main(String[] args) throws BadHanyuPinyinOutputFormatCombination { Map<String, String> fydmcPinYinMap = changeChinesePinyin("博主最帅"); System.out.println("首字母："+fydmcPinYinMap.get("groupPinyin")); System.out.println("拼音全称："+fydmcPinYinMap.get("fullPinyin")); System.out.println("拼音缩写："+fydmcPinYinMap.get("simplePinyin")); }
