1.在pom.xml里引入jar包

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

2.新建一个util

public class PinyinUtil {    /*     * 获取汉字简拼     */    public static String getPinYinHeadChar(String str) {        StringBuffer convert = new StringBuffer();        for (int j = 0; j < str.length(); j++) {            char word = str.charAt(j);            String[] pinyinArray = PinyinHelper.toHanyuPinyinStringArray(word);            if (pinyinArray != null) {                convert.append(pinyinArray[0].charAt(0));            } else {                convert.append(word);            }        }        return convert.toString();    }        /**     * 获取汉字全拼(无空格)     * @param src     * @return     */    public static String getPingYinTrimSpace(String src) {        char[] t1 = src.toCharArray();        String[] t2 = new String[t1.length];        HanyuPinyinOutputFormat t3 = new HanyuPinyinOutputFormat();        t3.setCaseType(HanyuPinyinCaseType.LOWERCASE);        t3.setToneType(HanyuPinyinToneType.WITHOUT_TONE);        t3.setVCharType(HanyuPinyinVCharType.WITH_V);        StringBuffer t4 = new StringBuffer();        try {            for (int i = 0; i < t1.length; i++) {                //                if (Character.toString(t1[i]).matches("[\\u4E00-\\u9FA5]+")) {                    t2 = PinyinHelper.toHanyuPinyinStringArray(t1[i], t3);                    t4.append(t2[0]);                } else {                    t4.append(Character.toString(t1[i]));                }            }                        return t4.toString().replaceAll(" ", "");        } catch (BadHanyuPinyinOutputFormatCombination e1) {            e1.printStackTrace();        }        return t4.toString();    }        public static void main(String[] args) {        System.out.println(getPingYinTrimSpace("兰溪小城"));    }}
