Java汉字转拼音(jar包法)

1、项目下需放入pinyin4j-2.5.0.jar，可再网上下载，这里不提供下载地址了

2、代码：
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.exception.BadHanyuPinyinOutputFormatCombination;

/**
* 汉字转换位汉语拼音，英文字符不变

*/
public class Cn2Spell {

/**
* 汉字转换位汉语拼音首字母，英文字符不变
* @param chines 汉字
* @return 拼音
*/
public static String converterToFirstSpell(String chines){
String pinyinName = "";
char[] nameChar = chines.toCharArray();
HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();
defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);
defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
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) {
e.printStackTrace();
}
}else{
pinyinName += nameChar[i];
}
}
return pinyinName;
}
