summernote复制无法保存图片问题
1、前端初始化
var imgReg = " /<img.*?(?:>|\\/>)/gi";
var srcReg = /src=[\'\"]?([^\'\"]*)[\'\"]?/i;
var reg = "[a-zA-z]+://[^\s]*";
$('.summernote1').summernote({
height: 200,
tabsize: 2,
lang: 'zh-CN',
callbacks : {
onPaste : function(e) {
console.log(e)
setTimeout(function() {
var str = $('.summernote1').summernote('code');
//匹配图片（g表示匹配所有结果i表示区分大小写）
var imgReg = /<img.*?(?:>|\/>)/gi;
//匹配src属性
var srcReg = /src=[\'\"]?([^\'\"]*)[\'\"]?/i;
var arr = str.match(imgReg);
if(arr != null) {
/* var formData = new FormData(); */
for (var i = 0; i < arr.length; i++) {
var src = arr[i].match(srcReg);
//当然你也可以替换src属性
if (src) {
$.ajax({
url : "${pageContext.request.contextPath}/knowledgePoint/saveParseImg.do?id=${knowledgePoint.id}&pathName=" + src[1],
type : 'post',
async: false,
/* data : formData, */
processData : false,
contentType : false,
success : function(data) {
str = str.replace(src[0], 'src="' + data + '"');
$('.summernote1').summernote('code', str);
}
});
}
}
}
}, 1000);
}
}
});
2、后台保存方法
@RequestMapping("/saveParseImg"）
@ResponseBody
public String savePasteImg(String id, String pathName, HttpServletRequest request) {
StringBuffer requestURL = request.getRequestURL();
String domainURL = requestURL.delete(requestURL.length() - request.getRequestURI().length(), requestURL.length()).append(request.getServletContext().getContextPath())
.append("/").toString();
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMddHHmmss");
String oriFileName = "";
String newFileName = "";
String errorMessage = null;
String type = "attachment";
HttpURLConnection conn = null;
BufferedInputStream bis = null;
FileOutputStream out = null;
InputStream in = null;
try {
String folder = request.getServletContext().getRealPath("");
StringBuffer savePath = new StringBuffer(folder).append(File.separator).append("knowledgebase").append(File.separator).append(id).append(File.separator)
.append(type).append(File.separator);
File f1 = new File(savePath.toString());
if (!f1.exists())
f1.mkdirs();
// 生成目录
String[] arr = pathName.split("/");
oriFileName = arr[arr.length - 1]; //pathName.split("/")[-1];
int index = oriFileName.indexOf(".");
String ext = oriFileName.substring(index);
if (ext.equals(".jpg") || ext.equals(".bmp") || ext.equals(".png") || ext.equals(".gif") || ext.equals(".pdg") || ext.equals(".jpeg")) {
type = "images";
StringBuffer savePath2 = new StringBuffer(folder).append(File.separator).append("knowledgebase").append(File.separator).append(id).append(File.separator).append(type).append(File.separator);
File f2 = new File(savePath2.toString());
if (!f2.exists())
f2.mkdirs();
int idRom = (int) ((Math.random() * 9 + 1) * 10000);
String rom = Integer.toString(idRom);
newFileName = dateFormat.format(new Date()) + rom + ext;
File uploadFile = new File(savePath2 + newFileName);
URL httpUrl = new URL(pathName);
conn = (HttpURLConnection) httpUrl.openConnection();
conn.setRequestMethod("GET");
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.connect();
out = new FileOutputStream(uploadFile);
in = conn.getInputStream();
bis = new BufferedInputStream(in);
byte[] bytes = new byte[1024];
int len = 0;
while ((len = bis.read(bytes)) != -1) {
out.write(bytes, 0, len);
}
StringBuffer url = new StringBuffer(domainURL).append(Constants.KNOWLEDGE_BASE_ROOT_PATH).append(id).append("/").append(type).append("/").append(newFileName);
String urlNew = url.toString();
return urlNew;
} else {
if (ext.equals(".jsp")) {
errorMessage = "拒绝上传JSP类型文件";
}
int idRom = (int) ((Math.random() * 9 + 1) * 10000);
String rom = Integer.toString(idRom);
newFileName = dateFormat.format(new Date()) + rom + ext;
File uploadFile = new File(savePath + newFileName);
URL httpUrl = new URL(pathName);
conn = (HttpURLConnection) httpUrl.openConnection();
conn.setRequestMethod("GET");
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.connect();
out = new FileOutputStream(uploadFile);
in = conn.getInputStream();
bis = new BufferedInputStream(in);
byte[] bytes = new byte[1024];
int len = 0;
while ((len = bis.read(bytes)) != -1) {
out.write(bytes, 0, len);
}
StringBuffer url = new StringBuffer(domainURL).append(Constants.KNOWLEDGE_BASE_ROOT_PATH).append(id).append("/").append(type).append("/").append(newFileName);
String urlNew = url.toString();
return urlNew;

} catch (Exception ex) {

return "";
