emoji 表情图片解决方法

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

Java代码


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.png

String 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

Java代码


public class ShareServlet extends HttpServlet {

private static EmojiConverter converter;

private static String imgpath="http://xx.xxxx.com/opt/siteimg/mika/emoji/unicode/";

@Override

public 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

Java代码


package com.fanbaobao.util;

import com.fanbaobao.util.EmojiConverter.Type;

public class EmojiFunction {

private static EmojiConverter converter;

private static String imgpath="http://xx.xxxx.com/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代码


<?xml version="1.0" encoding="UTF-8"?>

<taglib version="2.0" xmlns="http://java.sun.com/xml/ns/j2ee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/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

Html代码


<%@ taglib uri="/mikadata-tags" prefix="mk"%>

<td>${mk:emoji(dataObject.comment)}</td>
