springboot+ueditor+前后端分离
简介
- 项目采用前后端分离,故通过jsp+java的方式实现UEditor的集成
1. 官网下载ueditor资源,完整版
https://ueditor.baidu.com/website/download.html
2. 把相应文件拷贝到前端项目(net,php,jsp文件夹这里用不到)
3. 把jsp下面的源码,以及config.json文件拷贝到后台项目
4. 修改前台配置
4.1 页面
<script type="text/javascript" src="lib/config.js"></script>
<script type="text/javascript" charset="utf-8" src="lib/ueditor/1.4.3/ueditor.config.js"></script>
<script type="text/javascript" charset="utf-8" src="lib/ueditor/1.4.3/ueditor.all.js"></script>
<script type="text/javascript" charset="utf-8" src="lib/ueditor/1.4.3/lang/zh-cn/zh-cn.js"></script>
<div class="formControls col-xs-8">
<input name="text" id="text" value="" type="hidden"/>
<script id="editor" type="text/plain"></script>
</div>
初始化
<script>
var content = "";
var editor;
UE.Editor.prototype._bkGetActionUrl = UE.Editor.prototype.getActionUrl;
UE.Editor.prototype.getActionUrl = function(action) {
//只有在自己写后台代码实现的时候才需要这一块儿
if (action == 'uploadimage' /*|| action == 'uploadscrawl'*/ ) {
return domainDb + "operate-db/ueditor/uploadimage";
} else {
return this._bkGetActionUrl.call(this, action);
}
}
$(function () {
$("input[name='operator']").val(userName);
editor = UE.getEditor('editor'); //获取富文本
//初始化编辑器 （该处用于设置编辑器回显值）
editor.ready(function () {
editor.setContent(content);
});
})
</script>
4.2 config.js路径配置
//UEditor图片上传用到
var domainPage = "http://localhost:63342/operate-page/";
var domainDb = "http://localhost:8081/";
4.3 修改ueditor.config.js
4.4 修改ueditor.all.js
//设置图片最大宽度,以免撑出滚动条
'img{max-width:100%;}' +
5. 修改后台配置
5.1 配置application-dev.yml中路径
systemconfig:
##服务器路径
#static_server_path: /usr/local/operate/static
#static_server_domain: http://118.126.142.184:8080/static
#config_json_path: /usr/local/tomcat-1/webapps/operate-db/WEB-INF/classes/config.json
##本地路径
##上传路径
static_server_path: D:\java\apache-tomcat-7.0.91\webapps\tenxSteel4\pages\static
##读取路径
static_server_domain: http://localhost:8085/tenxSteel4/pages/static
config_json_path: src/main/resources/config.json
5.2 SystemConfig工具类读取dev配置文件中的路径
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import tenx.operate.common.util.StringUtils;
import java.util.ResourceBundle;
@Configuration
public class SystemConfig {
// 抽数据URL
public static String URL;
/**
* 数据库名称
*/
public static String STATIC_SEVER_PATH;
public static String STATIC_SEVER_DOMAIN;
public static String CONFIG_JSON_PATH;
@Value("${systemconfig.static_server_path}")
public void setStaticServerPath(String staticServerPath) {
SystemConfig.STATIC_SEVER_PATH = staticServerPath;
}
@Value("${systemconfig.config_json_path}")
public void setConfigJsonPath(String configJsonPath) { SystemConfig.CONFIG_JSON_PATH = configJsonPath;
}
@Value("${systemconfig.static_server_domain}")
public void setStaticSeverDomain(String staticServerDomain) { SystemConfig.STATIC_SEVER_DOMAIN = staticServerDomain;
}
/**
* 转换静态资源路径
* @param path
* @return
*/
public static String convertToUrl(String path){
if(StringUtils.isNullOrEmpty(path)){
return path;
}
return path.replaceAll("fs:",STATIC_SEVER_DOMAIN);
}
public static String convertToFile(String path){
if(StringUtils.isNullOrEmpty(path)){
return path;
}
return path.replaceAll("fs:",STATIC_SEVER_PATH);
}
}
5.3 修改ConfigManager
- 修改rootPath为dev中配置的图片上传路径
originalPath为dev中配置的config.json所在的路径
注:Linux为/usr/local/tomcat-1/webapps/operate-db/WEB-INF/classes/config.json
本地环境为:src/main/resources/config.json
5.4 修改BinaryUploader中的save方法
- 如果不做修改的话上传会报错(未找到上传数据)
原因:SpringMVC框架对含字节流的request进行了处理，此处传的是处理过的request，故获取不到字节流。
故修改原有代码,采用SpringMVC框架的解析器multipartResolverpublic static final State save(HttpServletRequest request, Map<String, Object> conf) { // FileItemStream fileStream = null; // boolean isAjaxUpload = request.getHeader( "X_Requested_With" ) != null; if (!ServletFileUpload.isMultipartContent(request)) { return new BaseState(false, AppInfo.NOT_MULTIPART_CONTENT); } // ServletFileUpload upload = new ServletFileUpload( // new DiskFileItemFactory()); // // if ( isAjaxUpload ) { // upload.setHeaderEncoding( "UTF-8" ); // } try { // FileItemIterator iterator = upload.getItemIterator(request); // // while (iterator.hasNext()) { // fileStream = iterator.next(); // // if (!fileStream.isFormField()) // break; // fileStream = null; // } // // if (fileStream == null) { // return new BaseState(false, AppInfo.NOTFOUND_UPLOAD_DATA); // } MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request; MultipartFile multipartFile = multipartRequest.getFile(conf.get("fieldName").toString()); if(multipartFile==null){ return new BaseState(false, AppInfo.NOTFOUND_UPLOAD_DATA); } String savePath = (String) conf.get("savePath"); //String originFileName = fileStream.getName(); String originFileName = multipartFile.getOriginalFilename(); String suffix = FileType.getSuffixByFilename(originFileName); originFileName = originFileName.substring(0, originFileName.length() - suffix.length()); savePath = savePath + suffix; long maxSize = ((Long) conf.get("maxSize")).longValue(); if (!validType(suffix, (String[]) conf.get("allowFiles"))) { return new BaseState(false, AppInfo.NOT_ALLOW_FILE_TYPE); } savePath = PathFormat.parse(savePath, originFileName); String physicalPath = (String) conf.get("rootPath") + savePath; //InputStream is = fileStream.openStream(); InputStream is = multipartFile.getInputStream(); State storageState = StorageManager.saveFileByInputStream(is, physicalPath, maxSize); is.close(); if (storageState.isSuccess()) { storageState.putInfo("url", PathFormat.format(savePath)); storageState.putInfo("type", suffix); storageState.putInfo("original", originFileName + suffix); } return storageState; // } catch (FileUploadException e) { // return new BaseState(false, AppInfo.PARSE_REQUEST_ERROR); } catch (IOException e) { } return new BaseState(false, AppInfo.IO_ERROR); }
5.5 修改config.json

6. bug汇总
6.1 单图上传提示"上传错误",但是图片已经上传成功
- 定位如下
- 全局搜索"上传错误",定位到simpleupload.loadError,form表单提交出现跨域的情况导致的,父页面http://localhost:63342/jianbang-page/hotSpot.html,子页面:http://localhost:8088/jianbang-report/ueditor/config?action=uploadimage。
因为浏览器的保护机制，在跨域的情况下是不能读取iframe里的内容的。这是为了防止一个网站读取另一个网站里的信息。所以这就造成了UEditor在上传的时候因为读不到iframe内容而提示“上传错误”这种错觉，但实际上已经上传成功了。故此时通过iframe.contentWindow.document是读取不到子页面上传结果信息的。
- 解决方案:舍弃callback回调,通过ajax提交的方式,在success中做上传后的处理逻辑
注释掉原来form提交逻辑// domUtils.on(iframe, 'load', callback); // form.action = utils.formatUrl(imageActionUrl + (imageActionUrl.indexOf('?') == -1 ? '?':'&') + params); // form.submit(); - 添加ajax提交方式
var params = utils.serializeParam(me.queryCommandValue('serverparam')) || ''; var action = utils.formatUrl(imageActionUrl + (imageActionUrl.indexOf('?') == -1 ? '?' : '&') + params); var formData = new FormData(); formData.append("upfile", form[0].files[0] ); $.ajax({ url: action, type: 'POST', cache: false, data: formData, processData: false, contentType: false, success: function (data) { // data = JSON.parse(data); var link, loader, body = (iframe.contentDocument || iframe.contentWindow.document).body, result = body.innerText || body.textContent || ''; link = me.options.imageUrlPrefix + data.url; if(data.state == 'SUCCESS' && data.url) { loader = me.document.getElementById(loadingId); loader.setAttribute('src', link); loader.setAttribute('_src', link); loader.setAttribute('title', data.title || ''); loader.setAttribute('alt', data.original || ''); loader.removeAttribute('id'); domUtils.removeClasses(loader, 'loadingclass'); } else { showErrorLoader && showErrorLoader(data.state); } form.reset(); } }); - 此外,也可以通过重定向的方法,参考https://blog.youkuaiyun.com/lnkToKing/article/details/79091753
