java使用百度富文本框_快速掌握百度富文本编辑器 UEditor 的使用

百度富文本编辑器UEditor是一款基于JavaScript的所见即所得富文本编辑器，可以轻松地将其集成到Java Web项目中，为用户提供更好的编辑体验。下面简单介绍一下在Java Web项目中使用百度富文本编辑器UEditor的方法。

1.下载UEditor

首先，需要从百度UEditor官网上下载UEditor的源代码。下载地址为：http://ueditor.baidu.com/website/download.html

2.将UEditor集成到Java Web项目中

下载完成后，将UEditor的源代码解压缩，并将解压后的文件夹复制到Java Web项目的WebContent目录下的任意一个子目录中（比如说WebContent/ueditor）。然后，将UEditor中的jsp目录下的所有文件复制到Java Web项目的WebContent目录下的任意一个子目录中（比如说WebContent/jsp）。

3.配置UEditor

在Java Web项目的WebContent目录下新建一个名为config.json的文件，该文件的内容如下：

{
"imageActionName": "uploadimage",
"imageFieldName": "upfile",
"imageMaxSize": 2048000,
"imageAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"],
"imageCompressEnable": true,
"imageCompressBorder": 1600,
"imageInsertAlign": "none",
"imageUrlPrefix": "",
"imagePathFormat": "/ueditor/jsp/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}",
"scrawlActionName": "uploadscrawl",
"scrawlFieldName": "upfile",
"scrawlPathFormat": "/ueditor/jsp/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}",
"scrawlMaxSize": 2048000,
"scrawlUrlPrefix": "",
"scrawlInsertAlign": "none",
"snapscreenActionName": "uploadimage",
"snapscreenPathFormat": "/ueditor/jsp/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}",
"snapscreenUrlPrefix": "",
"snapscreenInsertAlign": "none",
"catcherLocalDomain": ["127.0.0.1", "localhost", "img.baidu.com"],
"catcherActionName": "catchimage",
"catcherFieldName": "source",
"catcherPathFormat": "/ueditor/jsp/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}",
"catcherUrlPrefix": "",
"catcherMaxSize": 2048000,
"catcherAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"],
"videoActionName": "uploadvideo",
"videoFieldName": "upfile",
"videoPathFormat": "/ueditor/jsp/upload/video/{yyyy}{mm}{dd}/{time}{rand:6}",
"videoUrlPrefix": "",
"videoMaxSize": 102400000,
"videoAllowFiles": [
".flv", ".swf", ".mkv", ".avi", ".rm", ".rmvb", ".mpeg", ".mpg",
".ogg", ".ogv", ".mov", ".wmv", ".mp4", ".webm", ".mp3", ".wav", ".mid"
],
"fileActionName": "uploadfile",
"fileFieldName": "upfile",
"filePathFormat": "/ueditor/jsp/upload/file/{yyyy}{mm}{dd}/{time}{rand:6}",
"fileUrlPrefix": "",
"fileMaxSize": 51200000,
"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"
],
"imageManagerActionName": "listimage",
"imageManagerListPath": "/ueditor/jsp/upload/image/",
"imageManagerListSize": 20,
"imageManagerUrlPrefix": "",
"imageManagerInsertAlign": "none",
"imageManagerAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"],
"fileManagerActionName": "listfile",
"fileManagerListPath": "/ueditor/jsp/upload/file/",
"fileManagerUrlPrefix": "",
"fileManagerListSize": 20,
"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"
]
}

该文件是UEditor的配置文件，主要配置了上传文件的相关设置。

4.在JSP页面中使用UEditor

在需要使用UEditor的JSP页面中，添加如下代码：

<!-- 加载ueditor编辑器js文件 -->
<script type="text/javascript" src="${pageContext.request.contextPath}/ueditor/ueditor.config.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath}/ueditor/ueditor.all.min.js"></script>

<!-- 创建编辑器 -->
<script type="text/javascript">
var editor = UE.getEditor('editor');
</script>

其中，ueditor.config.js和ueditor.all.min.js是UEditor的核心文件，需要在页面中引入。editor是页面中一个div元素的id，表示要将该div元素转化为UEditor编辑器。

至此，就完成了在Java Web项目中使用百度富文本编辑器UEditor的集成。
