pinying4j使中文排序变得更简单
最近项目组做项目要用到中文排序的功能，为此在网上找了一些资料，为此特整理一下以下代码，共涉及到3个类
首先下载pinyin4j的jar包,
1.PingYingTest.java 这个是测试类
package pingying;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collections;
import java.util.List;

public class PingYingTest {

public static void sort() {
// 数组排序
//String[] array = { "xyz中abc-中国", "xyz中abc-美国" };
//List list1 = Arrays.asList(array);
//Arrays.sort(array, new PinyinComparator());
//System.out.println(list1);

// 集合排序
List list2 = new ArrayList();
list2.add("东软集团");
list2.add("春秋航空");
list2.add("太保");
list2.add("北京奔驰");
//list2.add("abc");
//list2.add("bcd");
Collections.sort(list2, new PinyinComparator());
System.out.println(list2);
}

public static void main(String[] args) {
PingYingTest.sort();

//String str1="abc";
//String str2="bcd";
//List list3 = new ArrayList();
//list3.add(str1);
//list3.add(str2);
//System.out.println(str1.compareTo(str2));
//Collections.sort(list3);
//for (int i = 0; i < list3.size(); i++) {
//System.out.println(list3.get(i));
//}


}
}
2.PinyinComparator.java比较器
package pingying;

import java.util.Comparator;

/**
* 拼音比较器
*
* @author xdli
*
*/
public class PinyinComparator implements Comparator

{
public int compare(Object o1, Object o2) {
String str1 = PinyinUtil.getPingYin((String) o1);
String str2 = PinyinUtil.getPingYin((String) o2);
System.out.println("str1-"+str1+"-str2:"+str2+"----:"+str1.compareTo(str2));
return str1.compareTo(str2);
}
}
//春 c 秋 q abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
//东 d 软 r
3.PinyinUtil.java 拼音工具类
package pingying;

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.*;

/**
* 拼音工具类
*
* @author xdli
*/
public class PinyinUtil {
/**
* 将字符串中的中文转化为拼音,其他字符不变
*
* @param inputString
* @return
*/
public static String getPingYin(String inputString) {
HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();
format.setCaseType(HanyuPinyinCaseType.LOWERCASE);
format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
format.setVCharType(HanyuPinyinVCharType.WITH_V);

char[] input = inputString.trim().toCharArray();
String output = "";

try {
for (int i = 0; i < input.length; i++) {
if (java.lang.Character.toString(input[i]).matches(
"[\\u4E00-\\u9FA5]+")) {
String[] temp = PinyinHelper.toHanyuPinyinStringArray(
input[i], format);
output += temp[0];
} else
output += java.lang.Character.toString(input[i]);
}
} catch (BadHanyuPinyinOutputFormatCombination e) {
e.printStackTrace();
}
return output;
}
}
