1:先弄到图片 上传到服务器上
2.下载 unicode 和 表情 映射关系xml
emoji4unicode.xml 在下面的rar 中
3.加入这个一个 转换类
package com.fanbaobao.util;import java.io.InputStream;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import javax.xml.namespace.QName;import javax.xml.stream.XMLEventReader;import javax.xml.stream.XMLInputFactory;import javax.xml.stream.XMLStreamException;import javax.xml.stream.events.Attribute;import javax.xml.stream.events.StartElement;import javax.xml.stream.events.XMLEvent;public class EmojiConverter {private EmojiConverter() {}enum Type {UNICODE, SOFTBANK};private Map<List<Integer>, String> convertMap;public static class Builder {private Type from;private Type to;public Builder from(Type type) {this.from = type;return this;}public Builder to(Type type) {this.to = type;return this;}public EmojiConverter build() {EmojiConverter converter = new EmojiConverter();readMap(converter);return converter;}private static final String TRIM_PATTERN = "[^0-9A-F]*";public void readMap(EmojiConverter converter) {Map<List<Integer>, String> result = new HashMap<List<Integer>, String>();converter.convertMap = result;XMLEventReader reader = null;try {XMLInputFactory factory = XMLInputFactory.newInstance();InputStream stream = EmojiConverter.class.getClassLoader().getResourceAsStream("emoji4unicode.xml");reader = factory.createXMLEventReader(stream);while (reader.hasNext()) {XMLEvent event = reader.nextEvent();if (event.isStartElement()) {StartElement element = (StartElement) event;if (element.getName().getLocalPart().equals("e")) {Attribute fromAttr = element.getAttributeByName(new QName(from.toString().toLowerCase()));Attribute toAttr = element.getAttributeByName(new QName(to.toString().toLowerCase()));if (fromAttr == null) {continue;}List<Integer> fromCodePoints = new ArrayList<Integer>();String from = fromAttr.getValue();if (from.length() > 6) {String[] froms = from.split("\\+");for (String part : froms) {fromCodePoints.add(Integer.parseInt(part.replaceAll(TRIM_PATTERN, ""),16));}} else {fromCodePoints.add(Integer.parseInt(from.replaceAll(TRIM_PATTERN, ""), 16));}if (toAttr == null) {result.put(fromCodePoints, null);} else {String to = toAttr.getValue();StringBuilder toBuilder = new StringBuilder();if (to.length() > 6) {String[] tos = to.split("\\+");for (String part : tos) {toBuilder.append(Character.toChars(Integer.parseInt(part.replaceAll(TRIM_PATTERN,""), 16)));}} else {toBuilder.append(Character.toChars(Integer.parseInt(to.replaceAll(TRIM_PATTERN, ""), 16)));}result.put(fromCodePoints, toBuilder.toString());}}}}reader.close();} catch (Exception e) {e.printStackTrace();} finally {if (reader != null) {try {reader.close();} catch (XMLStreamException e) {}}}}}public String convert(int width,int height,String imgpath,String input) {StringBuilder result = new StringBuilder();int[]codePoints = toCodePointArray(input);for(int i = 0; i < codePoints.length; i++){List<Integer> key2 = null;if(i + 1 < codePoints.length){key2 = new ArrayList<Integer>();key2.add(codePoints[i]);key2.add(codePoints[i + 1]);if(convertMap.containsKey(key2) || 65039==codePoints[i + 1]){ //处理 iphone5 xxxx-fe0f.pngString aa=Integer.toHexString(codePoints[i])+"-"+Integer.toHexString(codePoints[i+1]);String value = convertMap.get(key2);if(value != null || 65039==codePoints[i + 1]){result.append("<img width=\""+width+"px\" height=\""+height+"px\" style=\"vertical-align: bottom;\" src=\""+imgpath+"");result.append(aa);result.append(".png\"/>");}i++;continue;}}List<Integer> key1 = new ArrayList<Integer>();key1.add(codePoints[i]);if(convertMap.containsKey(key1)){String aa=Integer.toHexString(codePoints[i]);String value = convertMap.get(key1);if(value != null){result.append("<img width=\""+width+"px\" height=\""+height+"px\" style=\"vertical-align: bottom;\" src=\""+imgpath+"");result.append(aa);result.append(".png\"/>");//System.out.println("key:"+key1);//System.out.println("Map:"+value);}continue;}if(128529==codePoints[i]){ //处理空格result.append(" ");continue;}result.append(Character.toChars(codePoints[i]));}return result.toString();}int[] toCodePointArray(String str) {char[] ach = str.toCharArray();int len = ach.length;int[] acp = new int[Character.codePointCount(ach, 0, len)];int j = 0;for (int i = 0, cp; i < len; i += Character.charCount(cp)) {cp = Character.codePointAt(ach, i);acp[j++] = cp;}return acp;}}
3.调用 servlet
public class ShareServlet extends HttpServlet {private static EmojiConverter converter;private static String imgpath="/opt/siteimg/mika/emoji/unicode/";@Overridepublic void init() throws ServletException {converter = new EmojiConverter.Builder().from(Type.UNICODE).to(Type.SOFTBANK).build();}public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {FbbServiceClient service=null;try {String userid=request.getParameter("userid");String bid=request.getParameter("bid");if(userid!=null && bid!=null && userid.length()>0 && bid.length()>0){service=new FbbServiceClient();SnapService.Client client=service.open();SnapItem item=client.getItemByIdS(Long.valueOf(userid),Long.valueOf(bid));//进行转换if(item.getUserName()!=null && item.getUserName().length()>0)item.setUserName(converter.convert(20,20,imgpath,item.getUserName()));if(item.getItemName()!=null && item.getItemName().length()>0)item.setItemName(converter.convert(20,20,imgpath,item.getItemName()));request.setAttribute("SnapItem", item);request.getRequestDispatcher("/wxshare.jsp").forward(request, response);}} catch (Exception e) {e.printStackTrace();logger.error("errorcode ::: " + e.getMessage(), e);}finally{if(service!=null)service.close();}}}
4.写成一个ELfunction 在jsp EL 表达式中 使用
package com.fanbaobao.util;import com.fanbaobao.util.EmojiConverter.Type;public class EmojiFunction {private static EmojiConverter converter;private static String imgpath="/opt/siteimg/mika/emoji/unicode/";static{converter = new EmojiConverter.Builder().from(Type.UNICODE).to(Type.SOFTBANK).build();}public static String emoji(String arg){return emojiFun(null,null,arg);}public static String emojiFun(Integer width,Integer height,String arg){if(width==null){width=20;}if(height==null){height=20;}return converter.convert(width.intValue(),height.intValue(),imgpath,arg);}}
5;编写 tld文件
<?xml version="1.0" encoding="UTF-8"?><taglib version="2.0" xmlns="/xml/ns/j2ee"xmlns:xsi="/2001/XMLSchema-instance"xsi:schemaLocation="/xml/ns/j2ee web-jsptaglibrary_2_0.xsd"><tlib-version>1.0</tlib-version><short-name>mk</short-name><uri>/mikadata-tags</uri><function> <name>emoji</name><function-class>com.fanbaobao.util.EmojiFunction</function-class> <function-signature> java.lang.String emoji(java.lang.String)</function-signature> </function><function> <name>emojiFun</name><function-class>com.fanbaobao.util.EmojiFunction</function-class> <function-signature> java.lang.String emojiFun(java.lang.Integer,java.lang.Integer,java.lang.String)</function-signature> </function></taglib>
6:jsp中使用
<%@ taglib uri="/mikadata-tags" prefix="mk"%><td>${mk:emoji(ment)}</td>
