百度富文本编辑器ueditor/jsp版的简单使用,可上传图片和附件

时间:2024-02-19 13:23:38

~~经过一上午的时间,终于把ueditor编辑器搞出来了,仅做记录

#完成的样子

1,首先在官网下载对应的插件 【附下载地址:http://ueditor.baidu.com/website/download.html】

   本人使用的是Java语言 ,框架是ssm+maven

2,解压文件,在自己项目的根目录下新建文件夹 ueditor,把utf8-jsp中文件复制粘贴到ueditor文件夹下

3,新建一个ueditorTest.jsp,把文件夹中index.html中的HTML代码复制粘贴到这个jsp中,引入下面这四个js和css

<%@ page language="java" contentType="text/html; charset=UTF-8"  pageEncoding="UTF-8"%>
<%@include file="/WEB-INF/jsp/common/tag.jsp" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
    <title>完整demo</title>
    <meta http-equiv="Content-Type" content="text/html;charset=utf-8"/>
    <script type="text/javascript" charset="utf-8" src="${pageContext.request.contextPath}/assets/js/jquery.min.js"></script>
    <script type="text/javascript" charset="utf-8" src="${pageContext.request.contextPath}/ueditor/ueditor.config.js"></script>
    <script type="text/javascript" charset="utf-8" src="${pageContext.request.contextPath}/ueditor/ueditor.all.min.js"> </script>
    <!--建议手动加在语言,避免在ie下有时因为加载语言失败导致编辑器加载失败-->
    <!--这里加载的语言文件会覆盖你在配置项目里添加的语言类型,比如你在配置项目里配置的是英文,这里加载的中文,那最后就是中文-->
    <script type="text/javascript" charset="utf-8" src="${pageContext.request.contextPath}/ueditor/lang/zh-cn/zh-cn.js"></script>
    <style type="text/css">
        div{
            width:100%;
        }
    </style>
</head>
<body>
    <div>
    <h1>完整demo</h1>
    <textarea name="content"  id="editor"  style="width:820px;height:200px;"></textarea>
</div> 

  <script type="text/javascript">
    //实例化编辑器
    var ue = UE.getEditor(\'editor\');
  </script

</body>
</html>

 

4,我使用的是maven管理jar,所以/ueditor/jsp/lib下的前四个jar包在pom.xml引入,ueditor-1.1.2.jar可放在/WEB-INF/下lib文件夹中(没有就新建一个),并bulidpath

 

5,修改配置文件ueditor.config.js中的两处代码


  //【需要改的第一处:】
    var URL = window.UEDITOR_HOME_URL || "/xxxxx/ueditor/"; //xxxxx为你项目名称,即此处为ueditor文件夹相对项目的路径

  

  window.UEDITOR_CONFIG = {

        //【需要改的第二处:】
       , serverUrl: "/xxxx/upload/enter" //需要修改的第二处路径,xxxx同样是你的项目名称,
              //upload为你要新建的controller的访问路径,enter为入口方法,controller具体代码在下文

 

* 6,这个很重要,config.json文件放的路径一定要按照上面5中 serverUrl: "/xxxx/upload/enter" 对应,放在根路径下upload文件夹中(没有就新建一个文件夹),否则会一直报错:请求后台配置错误,上传功能将不能正常使用!

config.json中内容根据实际情况修改config.json文件中三个参数

"imageActionName": "uploadimage",
"imageFieldName": "upfile", 

"imagePathFormat": "/ueditor/jsp/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}", 

如果上传的文件(图片或附件)位置不在自己项目中,可在"imageUrlPrefix": " "中加路径前缀访问到

 

7,接下来要新建一个controller.java(由于ueditor给的方案中,把Java代码写到了controller.jsp中了,为了方便,建此controller.java文件),作为ueditor上传图片和附件的入口函数。

其中有两个点需要注意:

(1)  上面代码中 , serverUrl: "/xxxx/upload/enter" 的 /upload 和 /enter跟下面代码中 mapper 对应

(2)  下面代码为controller.jsp中粘贴过来稍作改动而来

@Controller
@RequestMapping("/upload")
public class uploadController {

    @RequestMapping(value="/enter",method=RequestMethod.GET)
    public void enterUE(HttpServletRequest request,HttpServletResponse response) {
        try {
            request.setCharacterEncoding( "utf-8" );
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        response.setHeader("Content-Type" , "text/html");  
        String rootPath = request.getSession().getServletContext().getRealPath("/");  
        try {  
            String exec = new ActionEnter(request, rootPath).exec();  
            PrintWriter writer = response.getWriter();  
            writer.write(exec);  
            writer.flush();  
            writer.close();  
        } catch (IOException e) {  
            e.printStackTrace();  
        } 
    }
    
}

 

8,此时你可以访问ueditorTest.jsp,点击多图上传,会出现这个样子

 如果出现报错,说明第5步ueditor.config.js中路径配置错了

9,开始写上传图片和附件的代码了

首先在ueditor.jsp中的<script></script>标签中加入如下代码

//实例化编辑器
    var ue = UE.getEditor(\'editor\');

//根据不同action上传图片和附件
UE.Editor.prototype._bkGetActionUrl = UE.Editor.prototype.getActionUrl;
    UE.Editor.prototype.getActionUrl = function(action) {
        if (action == \'uploadimage\') {
            return \'${pageContext.request.contextPath}/upload/uploadimage\';
        } else if (action == \'uploadfile\') {
            return \'${pageContext.request.contextPath}/upload/uploadfile\';
        } else {
            return this._bkGetActionUrl.call(this, action);
        }
    }

再在controller中写对应方法

    /**
     * ueditor上传图片的方法
     * @param upfile 上传图片的文件
     * @param request 
     * @param response
     * @return
     */
    @RequestMapping(value="/uploadimage",method=RequestMethod.POST)
    @ResponseBody
    public Map<String, Object> uploadNewsImg(@RequestParam(value="upfile",required=false) MultipartFile upfile,HttpServletRequest request,HttpServletResponse response) {
        Date date = new Date();
        String upLoadPath = "\\upload\\file\\"+new SimpleDateFormat("yyyy\\MM\\").format(date);
        String path = upLoadPath;
        //图片后缀
        String last = upfile.getOriginalFilename().substring(upfile.getOriginalFilename().lastIndexOf("."), upfile.getOriginalFilename().length());
        
        String uuid = UUID.randomUUID().toString().replace("-", "");
        String fileName = uuid+last;
        
        File fileT = new File(path,fileName);
        if(!fileT.exists()){
            fileT.mkdirs();
        }
        Map<String, Object> result = new HashMap<String,Object>();
        try {
            upfile.transferTo(fileT);
        } catch (IllegalStateException e) {
            logger.error("富文本编辑器图片上传失败,参数异常:"+e);
        } catch (IOException e1) {
            logger.error("富文本编辑器图片上传失败io异常:"+e1);
        }
        result.put("state", "SUCCESS");
        result.put("url",  upLoadPath.replace("\\", "/")+fileName);
        result.put("original", "");
        result.put("type", last);
        result.put("size", upfile.getSize());
        result.put("title", fileName);
        return result;
    }
    
    
    /**
     * ueditor文件上传方法
     * @param upfile
     * @param request
     * @param response
     * @return
     */
    @RequestMapping(value="/uploadfile",method=RequestMethod.POST)
    @ResponseBody
    public Map<String, Object> uploadFile(@RequestParam(value="upfile",required=false) MultipartFile upfile,HttpServletRequest request,HttpServletResponse response) {
        Date date = new Date();
        String upLoadPath = "\\upload\\file\\"+new SimpleDateFormat("yyyy\\MM\\").format(date);
        String path = upLoadPath;
        //附件后缀
        String last = upfile.getOriginalFilename().substring(upfile.getOriginalFilename().lastIndexOf("."), upfile.getOriginalFilename().length());
        
        String uuid = UUID.randomUUID().toString().replace("-", "");
        String fileName = uuid+last;
        
        File fileT = new File(path,fileName);
        if(!fileT.exists()){
            fileT.mkdirs();
        }
        Map<String, Object> result = new HashMap<String,Object>();
        try {
            upfile.transferTo(fileT);
        } catch (IllegalStateException e) {
            logger.error("富文本编辑器文件上传失败,参数异常:"+e);
        } catch (IOException e1) {
            logger.error("富文本编辑器文件上传失败io异常:"+e1);
        }
        result.put("state", "SUCCESS");
        result.put("url", upLoadPath.replace("\\", "/")+fileName);
        result.put("original", "");
        result.put("type", last);
        result.put("size", upfile.getSize());
        result.put("title", fileName);
        return result;
    }

 

到此简单的上传图片和文件到此就完结了。有什么不足之处,欢迎指出!
