汉字转化为拼音

 

使用pinyin4j.jar即可。

 

package com.wangzhu.pinyin;



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 Pinyin {

    public static void main(String[] args) {

        Pinyin pinyin = new Pinyin();

        System.out.println(pinyin.getPinyin("好呀！呵呵!Welcome to ."));

        System.out.println(pinyin.getPinyinHeadChar("好呀！呵呵!Welcome to ."));

    }



    /**

     * 返回中文拼音

     * 

     * @param hanzi

     *            中文

     * @return 中文拼音

     */

    private String getPinyin(String hanzi) {

        StringBuffer pinyin = new StringBuffer();

        char[] hanziChar = hanzi.toCharArray();

        HanyuPinyinOutputFormat pinyinOutputFormat = new HanyuPinyinOutputFormat();

        pinyinOutputFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);

        pinyinOutputFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);

        pinyinOutputFormat.setVCharType(HanyuPinyinVCharType.WITH_V);

        try {

            for (int i = 0, len = hanziChar.length; i < len; i++) {

                if (Character.toString(hanziChar[i]).matches(

                        "[\\u4E00-\\u9FA5]+")) {



                    String[] tempArr = PinyinHelper.toHanyuPinyinStringArray(

                            hanziChar[i], pinyinOutputFormat);



                    pinyin.append(tempArr[0]);

                } else {

                    pinyin.append(Character.toString(hanziChar[i]));

                }

            }

        } catch (BadHanyuPinyinOutputFormatCombination e) {

            e.printStackTrace();

        }

        return pinyin.toString();

    }



    /**

     * 返回中文拼音的首字母

     * 

     * @param hanzi

     *            中文

     * @return 中文拼音首字母

     */

    protected String getPinyinHeadChar(String hanzi) {

        StringBuffer pinyinHead = new StringBuffer();

        for (int i = 0, len = hanzi.length(); i < len; i++) {

            char tempChar = hanzi.charAt(i);

            String[] tempArr = PinyinHelper.toHanyuPinyinStringArray(tempChar);

            if (null != tempArr) {

                pinyinHead.append(tempArr[0].charAt(0));

            } else {

                pinyinHead.append(tempChar);

            }

        }

        return pinyinHead.toString();

    }

}

结果：

haoya！hehe!Welcome to .
hy！hh!Welcome to .

 

 

以下是反射机制的调用：

 

package com.wangzhu.reflect;



import java.lang.reflect.InvocationTargetException;

import java.lang.reflect.Method;



public class TextReflect {



    /**

     * @param args

     * @throws ClassNotFoundException

     * @throws NoSuchMethodException

     * @throws SecurityException

     * @throws InstantiationException

     * @throws InvocationTargetException

     * @throws IllegalAccessException

     * @throws IllegalArgumentException

     */

    public static void main(String[] args) throws ClassNotFoundException,

            SecurityException, NoSuchMethodException, IllegalArgumentException,

            IllegalAccessException, InvocationTargetException,

            InstantiationException {

        Class<?> classForName = Class.forName("com.wangzhu.pinyin.Pinyin");

        Object obj = classForName.newInstance();

        Method[] methods = classForName.getDeclaredMethods();

        for (int i = 0, len = methods.length; i < len; i++) {

            System.out.println(methods[i].getName());

        }

        Method method = classForName.getDeclaredMethod("getPinyin",

                String.class);

        method.setAccessible(true);// 只有设置为true，才能访问该私有方法

        Object temp = method.invoke(obj, "开始啦！恩雅 ！之乎者也一眼在！Welcome the World!@");

        System.out.println(temp);

    }

}

结果：

main
getPinyin
getPinyinHeadChar
kaishila！enya ！zhihuzheyeyiyanzai！Welcome the World!@
