汉字转拼音(PinYin)

第一步

导入坐标jar包
<dependency>
        <groupId>com.belerweb</groupId>
    <artifactId>pinyin4j</artifactId>
        <version>2.5.1</version>
</dependency>

第二步
创建一个util

package MyTest;

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

public class PinyinUtil {

private HanyuPinyinOutputFormat format = null;
private String[] pinyin;       

public PinyinUtil() 
{
          format = new HanyuPinyinOutputFormat();
          format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);  
}          

//转换单个字符 
public String getCharacterPinYin(char c) 
{ 
          try
          {
                   pinyin = PinyinHelper.toHanyuPinyinStringArray(c, format);
          }
          catch(BadHanyuPinyinOutputFormatCombination e)
          {
                   e.printStackTrace();
          }

          // 如果c不是汉字，toHanyuPinyinStringArray会返回null 
          if(pinyin == null) return null;                   

          // 只取一个发音，如果是多音字，仅取第一个发音 
          return pinyin[0];    
}

//转换一个字符串 
public String getStringPinYin(String str) 
{ 
          StringBuilder sb = new StringBuilder(); 
          String tempPinyin = null; 
          for(int i = 0; i < str.length(); ++i) 
          { 
                   tempPinyin =getCharacterPinYin(str.charAt(i)); 
                   if(tempPinyin == null) 
                   { 
                            // 如果str.charAt(i)非汉字，则保持原样 
                            sb.append(str.charAt(i)); 
                   } 
                   else
                   { 
                            sb.append(tempPinyin); 
                   } 
          } 
          return sb.toString(); 
} 

}

第三步
测试
@Test
public void testPinying3(){
PinyinUtil pinyinUtil = new PinyinUtil();
String str = “丫头”;
String strPinyin = pinyinUtil.getStringPinYin(str);
System.out.println(strPinyin);
}
