业务需求:将用户中文名字根据拼音首字母分类排序
直接上代码:
引入依赖:
<dependency>
<groupId>com.belerweb</groupId>
<artifactId>pinyin4j</artifactId>
<version>2.5.0</version>
</dependency>
创建工具类:
import cn.newi.common.util.StringUtil;
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.BadHanyuPinyinOutputFormatCombination;
public class PinyinUtils {
/**
* 将字符串中的中文转化为拼音,英文字符不变
*
* @param inputString
* 汉字
* @return
*/
public static String getPingyin(String inputString) {
HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();
format.setCaseType(HanyuPinyinCaseType.LOWERCASE);
format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
format.setVCharType(HanyuPinyinVCharType.WITH_V);
String output = "";
if (!StringUtil.isEmpty(inputString) && !"null".equals(inputString)) {
char[] input = inputString.trim().toCharArray();
try {
String notChsTmp = "";
for (int i = 0; i < input.length; i++) {
if (java.lang.Character.toString(input[i]).matches("[\\u4E00-\\u9FA5]+")) {
if (!StringUtil.isEmpty(notChsTmp)){
output += notChsTmp;
output += " ";
notChsTmp = "";
}
String[] temp = PinyinHelper.toHanyuPinyinStringArray(input[i], format);
output += temp[0];
if (i < input.length - 1){
output += " ";
}
} else {
notChsTmp += java.lang.Character.toString(input[i]);
}
}
//循环外面如果最后一个不是中文,最后补加上非中文字符串
if (!StringUtil.isEmpty(notChsTmp)){
output += notChsTmp;
notChsTmp = "";
}
} catch (BadHanyuPinyinOutputFormatCombination e) {
e.printStackTrace();
}
}
return output;
}
/**
* 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 getShoupin(String chines) {
String pinyinName = "";
char[] nameChar = chines.toCharArray();
HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();

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;
}
public static void main(String[] args) {
System.out.println(getPingyin("张三001"));
System.out.println(getShoupin("张三001"));
}
}
结果:
