有时，我们需要将中文汉字转为拼音存储，例如用于检索时，直接输入拼音或者首字母也能检索出我们想要的结果，这时我们便需要将汉字转拼音
•1、首先我们在 pom.xml 文件中引入需要的 maven 依赖
com.belerweb pinyin4j 2.5.1
•2、汉字转拼音工具类代码如下 Pinyin4jUtil.java：
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.BadHanyuPinyinOutputFormatComb ination;

chines.toCharArray(); HanyuPinyinOutputFormat defaultFormat

ONE); for (int i = 0; i < nameChar.length; i++) { if (nameChar[i] >
128) { try { pinyinName +=
PinyinHelper.toHanyuPinyinStringArray(nameChar[i],
defaultFormat)[0].charAt(0); } catch
(BadHanyuPinyinOutputFormatCombination e)
{ System.out.println(”获得汉语拼音首字母异常:}" +
e.getMessage()); } } else { pinyinName += nameChar[i]; } } return
pinyinName; }
