Java open-source class library pinyin4j tool for converting Chinese characters to Chinese pinyin

Recently, in order to increase the matching rate of queries, the CMS system needs to add pinyin search fields. On the internet, it found the java open-source class library of pinyin4j, which provides conversion of Chinese to Chinese pinyin (and supports polyphonic words, I looked at his demo and decided to use it. Because in actual use, I need to consider the different arrangement and combination of polyphonic words. The following Code supports polyphonic words.
