汉字转拼音

1、先引入jar

                   <!-- 引入pinyin4J的依赖 -->

                   <dependency>

                            <groupId>com.belerweb</groupId>

                            <artifactId>pinyin4j</artifactId>

                            <version>2.5.0</version>

                   </dependency>

2、导入转换工具类
