将汉字转换为汉语拼音java实现

      有的时候我们需要将中文转换成汉语拼音，将汉字转换成汉语拼音其实挺简单。首先我找到了一个资源，是一个XML文件：TBL_Dict.xml ，这个文件中每个汉字作为一个节点，该节点下有该汉字对应的汉语拼音，我的方法就是读取这个文件。

import java.util.List;import org.dom4j.Element;import com.yesoft.jdbcgeneric.constant.ConstantEnum;public class HzChangeToPy {/** * 将中文字符串转换成汉语拼音 * @param wenzi * @return */public String toPinYin(String wenzi){//XMLReader是一个读取xml文件的工具类，getRootElement()是将读取的xml文件内容返回为Element类型，这里我们解析xml使用的是dom4j。XMLReader xmlReader = new XMLReader(ConstantEnum.PINYINXML.toString());Element commonElement = xmlReader.getRootElement();//Element wenziElement = commonElement.element("NewDataSet");String pyStr = "";List<Element> wenziList = commonElement.elements();String[] str = chai(wenzi);for(int i = 0;i < str.length;i++){for (Element el : wenziList) {String name = el.elementText("wenzi"); if (name.equals(str[i])) {pyStr += el.elementText("zimu");}}}return pyStr;}/** * 将中文字符串拆解为单个字的数组 * @param wenzi * @return */public String[] chai(String wenzi){int length = wenzi.length();String[] str = new String[length];for(int i = 0;i<length;i++){str[i] = wenzi.substring(i,i+1);}return str;}public static void main(String[] args){HzChangeToPy py = new HzChangeToPy();String srt = py.toPinYin("张三");System.out.println(srt); }}

      这样张三就能转换成zhangsan了。下面是读取文件的工具类：

package com.yesoft.jdbcgeneric.utils;import java.io.File;import java.net.URLDecoder;import org.dom4j.Document;import org.dom4j.Element;import org.dom4j.io.SAXReader;import com.yesoft.jdbcgeneric.job.ScanDataSourceCountJob;public class XMLReader {private Document xmlDoc;//private Element root;//private String fileName;PropertiesUtil pu = new PropertiesUtil();public XMLReader(String fileName) {this.fileName = fileName;readFile();}private Document readFile() {try {if (xmlDoc == null) {String xmlClassPath = pu.readValueV("pyXmlPath");// 使用SAXReader方式读取XML文件SAXReader saxReader = new SAXReader();String resourceListXmlPath = xmlClassPath + fileName;String realPath_resourceListXmlPath = ScanDataSourceCountJob.class.getResource(resourceListXmlPath).getFile();realPath_resourceListXmlPath = URLDecoder.decode(realPath_resourceListXmlPath,"UTF-8");File file = new File(realPath_resourceListXmlPath);// InputStream in =// ResourceXmlReader.class.getResourceAsStream(fileName);// 加载数据库XML配置文件，得到Document对象// xmlDoc = saxReader.read(in);xmlDoc = saxReader.read(file);}} catch (Exception e) {e.printStackTrace();}return xmlDoc;}public Document getXmlDoc() {return xmlDoc;}public void setXmlDoc(Document xmlDoc) {this.xmlDoc = xmlDoc;}public Element getRootElement() {if (root == null) {root = xmlDoc.getRootElement();}return root;}}
