Java 姓名转换拼音（支持单音多音字）

1. 引入pom依赖

<dependency>
     <groupId>com.belerweb</groupId>
     <artifactId>pinyin4j</artifactId>
     <version>2.5.0</version>
</dependency>

2. 拼音工具类

public class PinYinUtil {

    private PinYinUtil(){
        throw new IllegalStateException("Utility class");
    }

    private static final int ASCII_MIN_SIZE = 32;

    private static final int ASCII_MAX_SIZE = 125;

    /**
     * @Description: 汉字转换方法（数字与字母不转换）
     * @param ch: 单个字符
     * @return: java.lang.String[]
     **/
    public static String[] getPinyin(char ch) {
        try {
            HanyuPinyinOutputFormat outputFormat = new HanyuPinyinOutputFormat();
            outputFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
            outputFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);
            outputFormat.setVCharType(HanyuPinyinVCharType.WITH_V);
            //ASCII >=33 ASCII<=125的直接返回 ,ASCII码表：http://www.asciitable.com/
            if (ch >= ASCII_MIN_SIZE && ch <= ASCII_MAX_SIZE) {
                return new String[]{String.valueOf(ch)};
            }
            return distinct(PinyinHelper.toHanyuPinyinStringArray(ch, outputFormat));
        } catch (BadHanyuPinyinOutputFormatCombination e) {
            throw new IllegalStateException(e);
        }
    }

    private static String[] distinct(String[] arr) {
        if (arr == null || arr.length == 0) {
            return arr;
        }
        HashSet<String> set = new HashSet<>();
        for (String str : arr) {
            set.add(str);
        }
        return set.toArray(new String[0]);
    }

}

3. 调试

public static void main(String[] args) {
   String str = "王行藏度阿都为兴重朝";
   char[] chs = str.toCharArray();
   for(char ch : chs){
      System.out.println(ch+"\t"+ Arrays.toString(PinYinUtil.getPinyin(ch)));
   }
}

4. 运行结果

5. 项目接口返回Json场景
