叁歲伎倆 2023-10-11 19:42 5阅读 0赞

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;
    
    /**

    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"));
        }
