java获取中文拼音首字母及全拼的实践
使用Hutool工具类 官网链接
以下为Hutool支持的拼音库的pom坐标，你可以选择任意一个引入项目中，如果引入多个，Hutool会按照以上顺序选择第一个使用。

PS：其他实现方法
第一种:
直接上代码(有个别中文无法识别):
import java.io.UnsupportedEncodingException;
public class ChineseCharToEnUtil {
private final static int[] li_SecPosValue = { 1601, 1637, 1833, 2078, 2274,
2302, 2433, 2594, 2787, 3106, 3212, 3472, 3635, 3722, 3730, 3858,
4027, 4086, 4390, 4558, 4684, 4925, 5249, 5590 };
private final static String[] lc_FirstLetter = { "a", "b", "c", "d", "e",
"f", "g", "h", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s",
"t", "w", "x", "y", "z" };
public String getAllFirstLetter(String str) {
if (str == null || str.trim().length() == 0) {
return "";
}
String _str = "";
for (int i = 0; i < str.length(); i++) {
_str = _str + this.getFirstLetter(str.substring(i, i + 1));
}
return _str;
}
public String getFirstLetter(String chinese) {
if (chinese == null || chinese.trim().length() == 0) {
return "";
}
chinese = this.conversionStr(chinese, "GB2312", "ISO8859-1");
if (chinese.length() > 1) // 判断是不是汉字
{
int li_SectorCode = (int) chinese.charAt(0); // 汉字区码
int li_PositionCode = (int) chinese.charAt(1); // 汉字位码
li_SectorCode = li_SectorCode - 160;
li_PositionCode = li_PositionCode - 160;
int li_SecPosCode = li_SectorCode * 100 + li_PositionCode; // 汉字区位码
if (li_SecPosCode > 1600 && li_SecPosCode < 5590) {
for (int i = 0; i < 23; i++) {
if (li_SecPosCode >= li_SecPosValue[i]
&& li_SecPosCode < li_SecPosValue[i + 1]) {
chinese = lc_FirstLetter[i];
break;
}
}
} else // 非汉字字符,如图形符号或ASCII码
{
chinese = this.conversionStr(chinese, "ISO8859-1", "GB2312");
chinese = chinese.substring(0, 1);
}
}
return chinese;
}
private String conversionStr(String str, String charsetName,String toCharsetName) {
try {
str = new String(str.getBytes(charsetName), toCharsetName);
} catch (UnsupportedEncodingException ex) {
System.out.println("字符串编码转换异常：" + ex.getMessage());
}
return str;
}
public static void main(String[] args) {
ChineseCharToEnUtil cte = new ChineseCharToEnUtil();
System.out.println("获取拼音首字母："+ cte.getAllFirstLetter("广州"));
}
}
