| 上一篇文章 Java 汉字转拼音 介绍了Java 中利用Pinyin4j 实现汉字转拼音，但是对于多音字问题采取的是组合拼音方式，例如长沙 取拼音结果就是 changsha zhangsha。某些情况下我们希望能得到多音字的唯一拼音，此时就需要借助多音字字典了，原理很简单：给多音字一个默认的拼音并告诉计算机碰到哪些词的时候使用其它的拼音，例如 长 字，我们可以给它指定默认拼音为 zhang，并标识 长沙 拼音为 chang。
以上是自己搜集的一个多音字词典 duoyinzi_pinyin.txt
自己封装了一个获取汉字拼音 全拼和简拼的工具类 PinyinUtils，代码如下： - package com.ricky.java.suggestion.util;
