前幾天做了個(gè)報(bào)名秒殺功能，用戶需要輸入：
? ? ? ? ? ? ? ? 姓，名，姓拼音，名拼音
? ? ? ??中間使用到了pinyin4J,?記錄一下。

導(dǎo)入pinyin4j-2.5.0.jar

創(chuàng)建 Pinyin4jUtil。以下是具體代碼

最開(kāi)始的時(shí)候沒(méi)有考慮多音字，直接使用名轉(zhuǎn)拼音字符串相等。后來(lái)修改成了上文方式。
? ? ? ? 將字的拼音組合和傳入的拼音依次對(duì)比。當(dāng) pysurnameFlag 與pynameFlag都相等時(shí)，則輸入正確

注意：在默認(rèn)情況下 呂（LV） 使用工具類(lèi)得到的拼音是LU

需要使用 defaultFormat.setVCharType(HanyuPinyinVCharType.WITH_V);進(jìn)行單獨(dú)處理。
