SpringBoot整合富文字編輯器（UEditor）
阿新 • • 發佈：2019-01-02
UEditro是一款比較好用的富文字編輯器，所謂的富文字編輯器就是和伺服器互動的資料不是普通的字串檔案，而是一些內容包含比較廣的字串，一般是指的html頁面，目前比較好用的是百度的UEditor，到官方網站下載：
http://ueditor.baidu.com/website/download.html
1、首先在專案下新建ueditor資料夾，吧下載的ueditor檔案裡面的內容全部拷貝進去；
2、在我們需要使用富文字編輯器的頁面裡面引入ueditor：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8" 啟動程式，訪問效果如下：
在index.jsp增加如下程式碼，將資料提交到伺服器：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<script src="<%=path %>/ueditor/ueditor.config.js"></script>
<script src="<%=path %>/ueditor/ueditor.all.min.js"></script>
<script src="<%=path %>/ueditor/lang/zh-cn/zh-cn.js"></script>
<script type="text/javascript">
var editor = UE.getEditor('container');
function postDate() {
}
</script>
</head>
<body>
<form action="<%=path %>/news/addNews.do" method="post">
<textarea id="container" name="content" type="text/plain">這裡寫你的初始化內容</textarea>
<button id="btn" onclick="postDate()">提交</button>
</form>
</body>
</html>controller寫法：
package com.xingxue.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/news")
public class NewsController {
@RequestMapping("/addNews.do")
public String addNews(String content) {
System.out.println(content);
return "ok";
}
}測試結果
此時，我們伺服器已經能收到資料，就可以存入資料庫，或者生產靜態html檔案，
4、解決圖片問題：
先編寫好接收圖片的controller
package com.xingxue.controller;
import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStream;
import java.util.HashMap;
import java.util.Map;
import java.util.Random;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.util.FileCopyUtils;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.multipart.MultipartFile;
@Controller
@RequestMapping("/news")
public class NewsController {
@RequestMapping("/addNews.do")
public String addNews(String content) {
System.out.println(content);
return "ok";
}
@RequestMapping("/upload.do")
@ResponseBody
public Map<String, Object> images (MultipartFile upfile, HttpServletRequest request, HttpServletResponse response){
Map<String, Object> params = new HashMap<String, Object>();
System.out.println("1111111111111");
try{
String basePath = "e:/img"; //與properties檔案中lyz.uploading.url相同，未讀取到檔案資料時為basePath賦預設值
String visitUrl = "/upload/"; //與properties檔案中lyz.visit.url相同，未讀取到檔案資料時為visitUrl賦預設值
String ext = "abc" + upfile.getOriginalFilename();
String fileName = String.valueOf(System.currentTimeMillis()).concat("_").concat(""+new Random().nextInt(6)).concat(".").concat(ext);
StringBuilder sb = new StringBuilder();
//拼接儲存路徑
sb.append(basePath).append("/").append(fileName);
visitUrl = visitUrl.concat(fileName);
File f = new File(sb.toString());
if(!f.exists()){
f.getParentFile().mkdirs();
}
OutputStream out = new FileOutputStream(f);
FileCopyUtils.copy(upfile.getInputStream(), out);
params.put("state", "SUCCESS");
params.put("url", visitUrl);
params.put("size", upfile.getSize());
params.put("original", fileName);
params.put("type", upfile.getContentType());
} catch (Exception e){
params.put("state", "ERROR");
}
return params;
}
}該接收圖片有幾個細節：
第一： MultipartFile upfile 引數名必須和我們ueditro配置檔名字一樣：
返回資料型別不能錯誤：
state：上傳圖片的狀態
url：訪問圖片的路徑
ueditro配置檔案修改：
更改jspdiamante：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

<meta http-equiv="pragma" content="no-cache">

<script type="text/javascript">
var editor = UE.getEditor('container');
UE.Editor.prototype._bkGetActionUrl = UE.Editor.prototype.getActionUrl;
UE.Editor.prototype.getActionUrl = function(action){
if(action == '/news/upload.do'){
return '/news/upload.do';
}else{
return this._bkGetActionUrl.call(this, action);
}
}
</script>
</head>
<body>
<form action="<%=path %>/news/addNews.do" method="post">
<textarea id="container" name="content" type="text/plain">這裡寫你的初始化內容</textarea>
<button id="btn" onclick="postDate()">提交</button>
</form>
</body>
</html>注意：
return ‘/news/upload.do’; //ssm要帶專案名， springboot不需要帶專案名
測試效果：
注意：圖片的路徑我們可以用一個虛擬的圖片伺服器來模擬，需要修改controller的程式碼

//拼接儲存路徑

//寫到e盤
File f = new File(sb.toString());
if(!f.exists()){
f.getParentFile().mkdirs();
}
OutputStream out = new FileOutputStream(f);
FileCopyUtils.copy(upfile.getInputStream(), out);
//虛擬圖片伺服器
String visitUrl = "http://localhost:9999/ssm/";
visitUrl = visitUrl.concat(fileName);
f = new File("D:/server/project/ssm/" + fileName);
out = new FileOutputStream(f);
FileCopyUtils.copy(upfile.getInputStream(), out);
params.put("state", "SUCCESS");
params.put("url", visitUrl);
params.put("size", upfile.getSize());
params.put("original", fileName);
params.put("type", upfile.getContentType());
} catch (Exception e){
e.printStackTrace();
params.put("state", "ERROR");
}
return params;
}
