首先，加入pinyin4j-2.5.0.jar包，jar包在源码中有

写工具类

public class PingYinUtil {
    /**
     * 将字符串中的中文转化为拼音,其他字符不变
     * 
     * @param inputString
     * @return
     */
    public static String getPingYin(String inputString) {
        HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();
        format.setCaseType(HanyuPinyinCaseType.LOWERCASE);
        format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
        format.setVCharType(HanyuPinyinVCharType.WITH_V);
 
        char[] input = inputString.trim().toCharArray();
        String output = "";
 
        try {
            for (int i = 0; i < input.length; i++) {
                if (java.lang.Character.toString(input[i]).matches("[\\u4E00-\\u9FA5]+")) {
                    String[] temp = PinyinHelper.toHanyuPinyinStringArray(input[i], format);
                    output += temp[0];
                } else
                    output += java.lang.Character.toString(input[i]);
            }
        } catch (BadHanyuPinyinOutputFormatCombination e) {
            e.printStackTrace();
        }
        return output;
    }
    /**  
     * 获取汉字串拼音首字母，英文字符不变  
     * @param chinese 汉字串  
     * @return 汉语拼音首字母  
     */  
    public static String getFirstSpell(String chinese) {   
            StringBuffer pybf = new StringBuffer();   
            char[] arr = chinese.toCharArray();   
            HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();   
            defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);   
            defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);   
            for (int i = 0; i < arr.length; i++) {   
                    if (arr[i] > 128) {   
                            try {   
                                    String[] temp = PinyinHelper.toHanyuPinyinStringArray(arr[i], defaultFormat);   
                                    if (temp != null) {   
                                            pybf.append(temp[0].charAt(0));   
                                    }   
                            } catch (BadHanyuPinyinOutputFormatCombination e) {   
                                    e.printStackTrace();   
                            }   
                    } else {   
                            pybf.append(arr[i]);   
                    }   
            }   
            return pybf.toString().replaceAll("\\W", "").trim();   
    }   
    /**  
     * 获取汉字串拼音，英文字符不变  
     * @param chinese 汉字串  
     * @return 汉语拼音  
     */  
    public static String getFullSpell(String chinese) {   
            StringBuffer pybf = new StringBuffer();   
            char[] arr = chinese.toCharArray();   
            HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();   
            defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);   
            defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);   
            for (int i = 0; i < arr.length; i++) {   
                    if (arr[i] > 128) {   
                            try {   
                                    pybf.append(PinyinHelper.toHanyuPinyinStringArray(arr[i], defaultFormat)[0]);   
                            } catch (BadHanyuPinyinOutputFormatCombination e) {   
                                    e.printStackTrace();   
                            }   
                    } else {   
                            pybf.append(arr[i]);   
                    }   
            }   
            return pybf.toString();   
    }  
}

然后直接调接口就行

public class Test {
	public static void main(String[] args) {
		String str="汉字转拼音";
		System.out.println("原为："+str);
		System.out.println("转换后为："+PingYinUtil.getPingYin("汉字转拼音"));
	}
}

运行结果
