java將漢字轉換爲拼音

1.在pom.xml裏引入jar包

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

2.新建一個util

public class PinyinUtil {
    /*
     * 獲取漢字簡拼
     */
    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();
    }
    
    /**
     * 獲取漢字全拼(無空格)
     * @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("蘭溪小城"));
    }
}
