文章标签 spring jsp jar 优化 web app 文章分类 spring boot 后端开发

kindeditor富文本编辑器比较简单，但是提供代码的jsp，还有其带的三个lib文件夹下的jar。

如果简单在springboot使用，如果spring boot选用的是外部tomcat,可以参考上一篇点击打开链接，直接将jsp放在webapp下，将lib文件夹放在WEB-INF下，这样不用什么配置直接打war包，lib和jsp都会直接打进去

不过如果作为内嵌tomcat的话就不要用这种方法了，而且kindeditor提供的jsp写的实在是丑陋，我们只用它提供的html css js就可以了：

file_manager_json.jsp

这样代码就整洁很多，而且不用额外的依赖包

实用方法在html文件中：

	/** kindeditor begin**/
	var editor;
	KindEditor.ready(function(K) {
			  editor = K.create('textarea[name="content"]', {
				cssPath : '../kindeditor/plugins/code/prettify.css',
				uploadJson : 'upload_file_json',
				fileManagerJson : 'file_manager_json',
				allowFileManager : true,
				afterCreate : function() {
					var self = this;
					K.ctrl(document, 13, function() {
						self.sync();
						document.forms['example'].submit();
					});
					K.ctrl(self.edit.doc, 13, function() {
						self.sync();
						document.forms['example'].submit();
					});
				}
			});
			prettyPrint();
			console.log("kindeditor","loaded");
		});
	/**	kindeditor end **/
