JAVA汉字转拼音工具类

1.引入依赖

    <!-- 中文拼音转换 -->
        <dependency>
            <groupId>com.belerweb</groupId>
            <artifactId>pinyin4j</artifactId>
            <version>2.5.0</version>
        </dependency>

2.工具类代码如下

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.HanyuPinyinVCharType;
import net.sourceforge.pinyin4j.format.exception.BadHanyuPinyinOutputFormatCombination;

        formart.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
        formart.setVCharType(HanyuPinyinVCharType.WITH_V);
        char[] arrays = chineseCharacters.trim().toCharArray();
        String result = "";

                if (Character.toString(ti).matches("[\\u4e00-\\u9fa5]")) { //匹配是否是中文
                    String[] temp = PinyinHelper.toHanyuPinyinStringArray(ti, formart);
                    //利用Ascii码进行大写转换
                    char[] cs = temp[0].toCharArray();
                    cs[0] -= 32;
                    result += String.valueOf(cs);
                } else {
                    result += ti;
                }
            }
        } catch (BadHanyuPinyinOutputFormatCombination e) {
            e.printStackTrace();
        }

        return result;
    }
}
