java springboot中获取汉字拼音

第一步：pom.xml文件中引入pinyin4j依赖

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

第二步：新增PinYinUtil工具类

package test;

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;

/**

public class PinYinUtil {
    /**
     * 测试main方法
     * @param args
     */
    public static void main(String[] args) {
        System.out.println(toFirstChar("汉字转换为拼音").toUpperCase()); //转为首字母大写
        System.out.println(toPinyin("汉字转换为拼音"));
    }
    /**
     * 获取字符串拼音的第一个字母
     * @param chinese
     * @return
     */
    public static String toFirstChar(String chinese){
        String pinyinStr = "";
        char[] newChar = chinese.toCharArray();  //转为单个字符
        HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();
        defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);
        defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
        for (int i = 0; i < newChar.length; i++) {
            if (newChar[i] > 128) {
                try {
                    pinyinStr += PinyinHelper.toHanyuPinyinStringArray(newChar[i], defaultFormat)[0].charAt(0);
                } catch (BadHanyuPinyinOutputFormatCombination e) {
                    e.printStackTrace();
                }
            }else{
                pinyinStr += newChar[i];
            }
        }
        return pinyinStr;
    }

    /**
     * 汉字转为拼音
     * @param chinese
     * @return
     */
    public static String toPinyin(String chinese){
        String pinyinStr = "";
        char[] newChar = chinese.toCharArray();
        HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();
        defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);
        defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
        for (int i = 0; i < newChar.length; i++) {
            if (newChar[i] > 128) {
                try {
                    pinyinStr += PinyinHelper.toHanyuPinyinStringArray(newChar[i], defaultFormat)[0];
                } catch (BadHanyuPinyinOutputFormatCombination e) {
                    e.printStackTrace();
                }
            }else{
                pinyinStr += newChar[i];
            }
        }
        return pinyinStr;
    }
}

　　

第三步：调用PinYinUtil工具类静态方法实现汉字向拼音的转换

PinYinUtil.toPinyin(vo.getName())
