一、引言
相信大家做项目时，很多时候都会用到富文本编辑器。今天是2016年8月的最后一天，那么就给大家带来一篇关于JSP UEditor整合SpringMVC的文章吧，UEditor是百度的一款富文本编辑器产品，网址为：http://ueditor.baidu.com/website/ ， 但是直接使用Editor时，会将编辑的图片直接上传到服务器的项目所在路径，如果每次部署项目的时候，都是全量部署(删除服务器上原有项目，重新部署)，则之前上传的图片都会清空，所以，一般情况下，我们最好是将图片上传到服务器上某个单独的目录下，这样，即使我们全量部署项目，之前上传的图片也就不会丢失了。好，那我们一起来看如何将Editor整合，并将图片保存到单独的目录下。
二、准备
这里我们用的UEditor的版本是1.4.3.3 下载地址为：http://ueditor.baidu.com/build/build_down.php?n=ueditor&v=1_4_3_3-utf8-jsp
三、实战
1、新建项目，导入UEditor
这里，我们新建Maven工程ueditor，将下载的UEditor解压后重命名为ueditor，并将文件夹拷贝到webapp/static目录下，如下图所示：
2、导入jar包
如图：
3、编辑pom.xml

<aop:advisor advice-ref="advice" pointcut="execution(* com.lyz.**.service.impl.*.*(..))"/>
</aop:config>
</beans> 6、新建applications.properties
这个文件主要用来设置一些配置信息，比如图片访问路径，上传路径等，具体如下所示：
lyz.uploading.url=d:/lyz/static
lyz.visit.url=/upload/
lyz.resource.url=http://127.0.0.1:80997、配置log4j
#\\u8F93\\u51FA\\u5230\\u63A7\\u5236\\u53F0
log4j.appender.stout=org.apache.log4j.ConsoleAppender
log4j.appender.stout.layout=org.apache.log4j.PatternLayout
log4j.appender.stout.layout.ConversionPattern=[%p]%d{yyyy-MM-dd HH:mm:ss} %l: %m%n
#log4j.appender.stout.layout.ConversionPattern=[%p]%d{yyyy-MM-dd HH:mm:ss}: %m%n

log4j.appender.fout.file=d:/Tomcat_Project/logs/wine.log
#log4j.appender.fout.file=/opt/apache-tomcat-7.0.56/logs/wine.log
log4j.appender.fout.layout=org.apache.log4j.PatternLayout
log4j.appender.fout.layout.ConversionPattern=[%p]%d{yyyy-MM-dd HH:mm:ss} %l: %m%n
#log4j.appender.stout.layout.ConversionPattern=[%p]%d{yyyy-MM-dd HH:mm:ss}: %m%n
#\\u8F93\\u51FA\\u7EA7\\u522B
log4j.rootLogger=INFO, stout8、配置lyz-servlet
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"

<property name="suffix" value=".jsp" />
</bean>
<bean id="multipartResolver"

<property name="defaultEncoding" value="utf-8" />
<property name="maxUploadSize" value="10485760000" />
<property name="maxInMemorySize" value="40960" />
</bean>
</beans>9、建立实体类Shop
创建实体类主要的目的是方便运行整个项目框架，具体如下：
package com.lyz.entity;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
/**
* 实体类shop
* @author liuyazhuang
*
*/
@Entity
@Table(name="c_shop")
public class Shop implements Serializable {
private static final long serialVersionUID = -6980546472329430674L;
@Id
@Column(name="id")
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;
public Shop() {
super();
}
public Shop(Long id) {
super();
this.id = id;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
@Override
public String toString() {
return "Shop [id=" + id + "]";
}
}
10、创建读取properties文件的工具类LoadPropertiesDataUtils
package com.lyz.utils;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
/**
* 加载Properties文件数据的工具类
* @author liuyazhuang
*
*/
public final class LoadPropertiesDataUtils{
private volatile static Properties mProperties;
static{
mProperties = new Properties();
InputStream in = LoadPropertiesDataUtils.class.getResourceAsStream("/applications.properties");
try{
mProperties.load(in);
} catch (IOException e){
e.printStackTrace();
}
}
public static String getValue(String key){
if(mProperties == null) return "";
return mProperties.getProperty(key, "");
}
}
11、创建随机数工具类
这个类的主要作用是生成指定位数的随机数，具体如下所示：
package com.lyz.utils;
import java.util.Random;
/**
* 随机数工具类
* @author liuyazhuang
*
*/
public final class RandomUtils {
/**
* 获取指定位数的随机数
* @param num
* @return
*/
public static String getRandom(int num){
Random random = new Random();
StringBuilder sb = new StringBuilder();
for(int i = 0;i < num; i++){
sb.append(String.valueOf(random.nextInt(10)));
}
return sb.toString();
}
}
12、创建字符串工具类StringUtils
package com.lyz.utils;
/**
* 字符串工具类
* @author liuyazhuang
*
*/
public final class StringUtils {
/**
* 判断字符串是否为空
* @param str
* @return
*/
public static boolean isEmpty(String str){
return (str == null || "".equals(str.trim()));
}
/**
* 获取名称后缀
* @param name
* @return
*/
public static String getExt(String name){
if(name == null || "".equals(name) || !name.contains("."))
return "";
return name.substring(name.lastIndexOf(".")+1);
}
}
13、创建解决跨域的类CorsFilter
package com.lyz.utils.cors.filter;
import java.io.IOException;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.filter.OncePerRequestFilter;
/**
* 解决跨域
* @author liuyazhuang
*
*/
public class CorsFilter extends OncePerRequestFilter {
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
throws ServletException, IOException {
response.addHeader("Access-Control-Allow-Origin", "*");
response.addHeader("Access-Control-Allow-Methods",
"GET, POST, PUT, DELETE, OPTIONS");
response.addHeader("Access-Control-Allow-Headers",
"origin, content-type, accept, x-requested-with, sid, mycustom, smuser");
filterChain.doFilter(request, response);
}
}
14、创建跳转到首页的控制器类IndexController
package com.lyz.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
/**
* 首页controller，主要的功能是跳转到首页
* @author liuyazhuang
*
*/
@Controller
@RequestMapping(value="/index")
public class IndexController {
/**
* 跳转到首页
* @param request
* @param response
*/
@RequestMapping(value="/page", method = RequestMethod.GET)
public String page(HttpServletRequest request, HttpServletResponse response){
return "/index";
}
}
15、创建上传文件的类UploadImageController
package com.lyz.controller;
import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStream;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.util.FileCopyUtils;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;
import com.lyz.utils.LoadPropertiesDataUtils;
import com.lyz.utils.RandomUtils;
import com.lyz.utils.StringUtils;
/**
* 上传图片的controller
* @author liuyazhuang
*
*/
@Controller
@RequestMapping(value="/resource/upload")
public class UploadImageController {
/**
* 上传图片
* @param file
* @param request
* @param response
* @return
*/
@ResponseBody
@RequestMapping(value="/images")
public Map<String, Object> images (MultipartFile upfile, HttpServletRequest request, HttpServletResponse response){
Map<String, Object> params = new HashMap<String, Object>();
try{
String basePath = LoadPropertiesDataUtils.getValue("lyz.uploading.url");
String visitUrl = LoadPropertiesDataUtils.getValue("lyz.visit.url");
if(basePath == null || "".equals(basePath)){
basePath = "d:/lyz/static"; //与properties文件中lyz.uploading.url相同，未读取到文件数据时为basePath赋默认值
}
if(visitUrl == null || "".equals(visitUrl)){
visitUrl = "/upload/"; //与properties文件中lyz.visit.url相同，未读取到文件数据时为visitUrl赋默认值
}
String ext = StringUtils.getExt(upfile.getOriginalFilename());
String fileName = String.valueOf(System.currentTimeMillis()).concat("_").concat(RandomUtils.getRandom(6)).concat(".").concat(ext);
StringBuilder sb = new StringBuilder();
//拼接保存路径
sb.append(basePath).append("/").append(fileName);
visitUrl = visitUrl.concat(fileName);
File f = new File(sb.toString());
if(!f.exists()){
f.getParentFile().mkdirs();
}
OutputStream out = new FileOutputStream(f);
FileCopyUtils.copy(upfile.getInputStream(), out);
params.put("state", "SUCCESS");
params.put("url", visitUrl);
params.put("size", upfile.getSize());
params.put("original", fileName);
params.put("type", upfile.getContentType());
} catch (Exception e){
params.put("state", "ERROR");
}
return params;
}
}
16、引入jquery
我们在webapp/static目录下创建lib目录，然后将jquery导入到lib目录下，如下图所示：
17、创建index.jsp
在webapp/WEB_INF/jsp目录下创建index.jsp，具体如下：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>UEditor</title>
<script type="text/javascript">
var basePath = "<%=basePath%>";
</script>
<script type="text/javascript" src="../static/lib/jquery-1.12.0.min.js"></script>
<script type="text/javascript" src="../static/ueditor/ueditor.config.js"></script>
<script type="text/javascript" src="../static/ueditor/ueditor.all.js"></script>
<script type="text/javascript" src="../static/ueditor/lang/zh-cn/zh-cn.js"></script>
<script type="text/javascript" src="../static/index/index.js"></script>
</head>
<body>
<div>
<textarea id="myEditor"></textarea>
</div>
</body>
</html>18、创建index.js文件
我们在webapp/static目录下创建index文件夹，并在index文件夹中创建index.js，主要内容如下：
$(function(){
//富文本编辑器
UE.getEditor('myEditor')
UE.Editor.prototype._bkGetActionUrl = UE.Editor.prototype.getActionUrl;
UE.Editor.prototype.getActionUrl = function(action){
if(action == '/resource/upload/images'){
return basePath+'resource/upload/images';
}else{
return this._bkGetActionUrl.call(this, action);
}
}
});19、编辑UEditor的config.json文件
编辑后的文件如下图所示：
/* 前后端通信相关的配置,注释只允许使用多行方式 */
{
/* 上传图片配置项 */
"imageActionName": "/resource/upload/images", /* 执行上传图片的action名称 */
"imageFieldName": "upfile", /* 提交的图片表单名称 */

"catcherActionName": "catchimage", /* 执行抓取远程图片的action名称 */
"catcherFieldName": "source", /* 提交的图片列表表单名称 */
"catcherPathFormat": "/ueditor/jsp/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}", /* 上传保存路径,可以自定义保存路径和文件名格式 */
"catcherUrlPrefix": "", /* 图片访问路径前缀 */
"catcherMaxSize": 2048000, /* 上传大小限制，单位B */
"catcherAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"], /* 抓取图片格式显示 */
/* 上传视频配置 */
"videoActionName": "uploadvideo", /* 执行上传视频的action名称 */
"videoFieldName": "upfile", /* 提交的视频表单名称 */
"videoPathFormat": "/ueditor/jsp/upload/video/{yyyy}{mm}{dd}/{time}{rand:6}", /* 上传保存路径,可以自定义保存路径和文件名格式 */
"videoUrlPrefix": "", /* 视频访问路径前缀 */
"videoMaxSize": 102400000, /* 上传大小限制，单位B，默认100MB */
"videoAllowFiles": [
".flv", ".swf", ".mkv", ".avi", ".rm", ".rmvb", ".mpeg", ".mpg",
".ogg", ".ogv", ".mov", ".wmv", ".mp4", ".webm", ".mp3", ".wav", ".mid"], /* 上传视频格式显示 */
/* 上传文件配置 */
"fileActionName": "uploadfile", /* controller里,执行上传视频的action名称 */
"fileFieldName": "upfile", /* 提交的文件表单名称 */
"filePathFormat": "/ueditor/jsp/upload/file/{yyyy}{mm}{dd}/{time}{rand:6}", /* 上传保存路径,可以自定义保存路径和文件名格式 */
"fileUrlPrefix": "", /* 文件访问路径前缀 */
"fileMaxSize": 51200000, /* 上传大小限制，单位B，默认50MB */
"fileAllowFiles": [
".png", ".jpg", ".jpeg", ".gif", ".bmp",
".flv", ".swf", ".mkv", ".avi", ".rm", ".rmvb", ".mpeg", ".mpg",
".ogg", ".ogv", ".mov", ".wmv", ".mp4", ".webm", ".mp3", ".wav", ".mid",
".rar", ".zip", ".tar", ".gz", ".7z", ".bz2", ".cab", ".iso",
".doc", ".docx", ".xls", ".xlsx", ".ppt", ".pptx", ".pdf", ".txt", ".md", ".xml"
], /* 上传文件格式显示 */
/* 列出指定目录下的图片 */
"imageManagerActionName": "listimage", /* 执行图片管理的action名称 */
"imageManagerListPath": "/ueditor/jsp/upload/image/", /* 指定要列出图片的目录 */
"imageManagerListSize": 20, /* 每次列出文件数量 */
"imageManagerUrlPrefix": "", /* 图片访问路径前缀 */
"imageManagerInsertAlign": "none", /* 插入的图片浮动方式 */
"imageManagerAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"], /* 列出的文件类型 */
/* 列出指定目录下的文件 */
"fileManagerActionName": "listfile", /* 执行文件管理的action名称 */
"fileManagerListPath": "/ueditor/jsp/upload/file/", /* 指定要列出文件的目录 */
"fileManagerUrlPrefix": "", /* 文件访问路径前缀 */
"fileManagerListSize": 20, /* 每次列出文件数量 */
"fileManagerAllowFiles": [
".png", ".jpg", ".jpeg", ".gif", ".bmp",
".flv", ".swf", ".mkv", ".avi", ".rm", ".rmvb", ".mpeg", ".mpg",
".ogg", ".ogv", ".mov", ".wmv", ".mp4", ".webm", ".mp3", ".wav", ".mid",
".rar", ".zip", ".tar", ".gz", ".7z", ".bz2", ".cab", ".iso",
".doc", ".docx", ".xls", ".xlsx", ".ppt", ".pptx", ".pdf", ".txt", ".md", ".xml"
] /* 列出的文件类型 */
}
imageUrlPrefix为图片访问前缀。
20、配置tomcat server.xml文件
由于我们将图片放到了项目外面，独立于tomcat，所以我们要在tomcat的server.xml文件中设置虚拟路径，如下在<Host></Host>节点中添加如下代码：
<Context docBase="d:/lyz/static" path="/upload" reloadable="true"/>如下图所示：
至此，我们完成了整个项目的开发，下面我们来运行这个项目
四、运行测试
我们将项目发布到tomcat,在浏览器地址栏输入http://127.0.0.1:8099/ueditor/index/page,原因是我将tomcat端口设置为8099,
此时，查看我的图片保存路径d:/lyz/static
没有任何图片。那现在我们编辑图片吧。如下图，我在UEditor中编辑了一张图片：
我们再打开d:/lyz/static目录：
图片已经上传到我们的指定的配置目录中了。
至此整个工程创建运行结束。
