Java 漢字轉拼音

一、引入Maven依賴

<dependency>
	<groupId>com.belerweb</groupId>
	<artifactId>pinyin4j</artifactId>
	<version>2.5.0</version>
</dependency>
           

二、代碼

import com.gyyjy.portal.pojo.cms.sm.SelectTreeVO;
import net.sourceforge.pinyin4j.PinyinHelper;

import java.util.Comparator;

/**
 * @author gmd
 * @description 漢字轉拼音
 * @date 2021-08-30
 */
public class Chinese2Pinyin {

	/**
	* @param str 漢字
	* @return 漢字對應的拼音
	*/
    private String toPinYinString(String str) {
        StringBuilder sb = new StringBuilder();
        String[] arr = null;
        for (int i = 0; i < str.length(); i++) {
            arr = PinyinHelper.toHanyuPinyinStringArray(str.charAt(i));
            if (arr != null && arr.length > 0) {
                for (String string : arr) {
                    sb.append(string);
                }
            } else {
                sb.append(str.charAt(i));
            }
        }
        return sb.toString();
    }

	/**
	* 測試
	*/
    public static void main(String[] args) {
        Chinese2Pinyin chinese = new Chinese2Pinyin();
        System.out.println(chinese.toPinYinString("天河人員1"));
        System.out.println(chinese.toPinYinString("天河人員2"));
    }
	
}
           

三、測試
