JAVA-漢字拼音處理

1、依賴jar包

maven倉庫：

<repository>
    <id>alimaven</id>
    <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
</repository>

GAV：

        <dependency>
            <groupId>com.belerweb</groupId>
            <artifactId>pinyin4j</artifactId>
            <version>2.5.1</version>
        </dependency>

2、工具類

package com.xxx.utils;

import net.sourceforge.pinyin4j.format.HanyuPinyinCaseType;
import net.sourceforge.pinyin4j.format.HanyuPinyinOutputFormat;

import net.sourceforge.pinyin4j.format.exception.BadHanyuPinyinOutputFormatCombination;
import org.junit.Test;
import org.springframework.stereotype.Component;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

        System.out.println(cleanChar(s));
        //JGLZabc123
        //jugeliziabc123
