spring boot集成ckeditor以及上传图片
将上面的下载好的demo放入所需的项目工程中去
在需要引入富文本编辑器的地方加上这段代码
Ckeditor编辑器上传图片
/**
-
ckeditor图片上传
-
@Title imageUpload
-
@param request
-
@param response
*/
@RequestMapping(value="/admin/imageUpload", method=RequestMethod.POST)
public void imageUpload(HttpServletRequest request, HttpServletResponse response) {
String DirectoryName = “upload/article”;
String relativePath = env.getProperty(“image.file.article.dir”);
System.out.println(“relativePath=========”+relativePath);
try {
ImageUploadUtil.ckeditor(request, response, DirectoryName,relativePath);
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
Controller 层spring MVC
/**
-
ckeditor文件上传功能，回调，传回图片路径，实现预览效果。
-
@Title ckeditor
-
@param request
-
@param response
-
@param DirectoryName
-
文件上传目录：比如upload(无需带前面的/) upload/…
-
@throws IOException
*/
public static void ckeditor(HttpServletRequest request, HttpServletResponse response, String DirectoryName,String relativePath)
throws IOException {
String fileName = upload(request, DirectoryName,relativePath);
// 结合ckeditor功能
// imageContextPath为图片在服务器地址，如upload/123.jpg,非绝对路径
String imageContextPath = request.getContextPath() + “/” + DirectoryName + “/” + fileName;
response.setContentType(“text/html;charset=UTF-8”);
String callback = request.getParameter(“CKEditorFuncNum”);
PrintWriter out = response.getWriter();
out.println("<script type=“text/javascript”>");
out.println(“window.parent.CKEDITOR.tools.callFunction(” + callback + “,’” + imageContextPath + “’,’’” + “)”);
out.println("");
out.flush();
out.close();
