Java汉字转拼音pinyin4j用法详解

HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();
// 控制大小写
// UPPERCASE：大写 (ZHONG)
// LOWERCASE：小写 (zhong)
defaultFormat.setCaseType(HanyuPinyinCaseType.UPPERCASE);
// WITHOUT_TONE：无音标 (zhong)
// WITH_TONE_NUMBER：1-4数字表示英标 (zhong4)
// WITH_TONE_MARK：直接用音标符（必须WITH_U_UNICODE否则异常） (zhòng)
defaultFormat.setToneType(HanyuPinyinToneType.WITH_TONE_NUMBER);
// WITH_V：用v表示ü (nv)
// WITH_U_AND_COLON：用"u:"表示ü (nu:)
// WITH_U_UNICODE：直接用ü (nü)
defaultFormat.setVCharType(HanyuPinyinVCharType.WITH_U_UNICODE);
// oHanyuPinyinStringArray如果传入的字符不是汉字不能转换成拼音，那么会直接返回null。
String[] pinyin = PinyinHelper.toHanyuPinyinStringArray('重', defaultFormat);
