JAVA中拼音工具类

Posted 2021-04-04 zblwyj

使用前导入pinyin4j的jar包到工程中：

<dependency>
          <groupId>com.belerweb</groupId>
          <artifactId>pinyin4j</artifactId>
          <version>2.5.0</version>
</dependency>

下面是，封装好的工具类：

package utils;

import net.sourceforge.pinyin4j.PinyinHelper;
import net.sourceforge.pinyin4j.format.HanyuPinyinCaseType;
import net.sourceforge.pinyin4j.format.HanyuPinyinOutputFormat;
import net.sourceforge.pinyin4j.format.HanyuPinyinToneType;
import net.sourceforge.pinyin4j.format.exception.BadHanyuPinyinOutputFormatCombination;
