导入maven依赖

		<!--导入pinyin4j库-->
        <dependency>
            <groupId>com.belerweb</groupId>
            <artifactId>pinyin4j</artifactId>
            <version>2.5.1</version>
        </dependency>

demo如下：

import com.github.stuxuhai.jpinyin.PinyinHelper;

public class PinyinUtils {
	public static void main(String[] args) {
   
        char c = '刘';
        char[] xx = new char[]{'对', '方'};
        for (int i = 0; i < xx.length; i++) {
            String[] pinyinArray = PinyinHelper.convertToPinyinArray(xx[i]);
            StringBuilder pinyinBuilder = new StringBuilder();
            for (String pinyin : pinyinArray) {
                pinyinBuilder.append(pinyin);
            }
            // 带声调
            System.out.print(pinyinBuilder.toString());
        }
    }
}

结尾：
这个jar依赖还存在import net.sourceforge.pinyin4j.PinyinHelper引用

demo中使用的是github的，根据个人实际情况决定包的引用
