下載ueditor-jsp版的資源包,解壓並放到webapp目錄下
在要引入的jsp頁面引入js檔案
注*:不用引入css檔案
<script src="<c:url value="/model/ueditor/ueditor.config.js"></script>
<script src="<c:url value="/model/ueditor/ueditor.all.min.js"></script>
<script src="<c:url value="/model/ueditor/lang/zh-cn/zh-cn.js"></script>

ueditor.config.js
中要做些常用的配置
// ueditor目錄所在專案下的絕對路徑,不配置的話,jsp頁面會引入不到ueditor編輯器
var URL = window.UEDITOR_HOME_URL || "/model/ueditor/";
// 編輯器的寬高設定
initialFrameWidth:'80%' //初始化編輯器寬度,預設1000
initialFrameHeight:400 //初始化編輯器高度,預設320

在form表單中加入textarea標籤
<textarea type="text" name="reportContent" id="reportContent"></textarea>
<script type="text/javascript">
UE.getEditor('reportContent')
UE.Editor.prototype._bkGetActionUrl = UE.Editor.prototype.getActionUrl
UE.Editor.prototype.getActionUrl = function (action) {

IDEA中需要配置單獨的虛擬路徑對映,如果直接修改tomcat中的server.xml配置,配置不會生效以上程式碼專門用於檔案上傳,表單提交和以前一樣,沒什麼變化
- tomcat執行配置 -> edit configurations.. -> Deployment -> 新增External Source -> 選擇本地資料夾 -> Application context(配置tomcat對映資料夾)
- 如果將專案部署到tomcat中去的話,就要配置server.xml了,在Host標籤下配置
<!-- path為專案訪問的虛擬路勁 : docBase為本地路徑 -->
<Context path="/ICMS" docBase="D:\upFiles" reloadable="true" />
