xheditor上传图片的java实现

　　最近一个项目中因为框架的原因，很多文本编辑器都不兼容，最后找到xheditor，这个富文本编辑器的确不错，功能基本都能满足，只是上传图片的java接口需要自己写，因此，测试了两种方法，最终成功。分享给大家。

xheditor官方给出了上传接口。因此我们只需要调用自己的Action按照它指定的json格式返回一个json数据就可以了。aaarticlea/png;base64,iVBORw0KGgoAAAANSUhEUgAABMMAAACFCAIAAADZxagOAAAgAElEQVR4nO2cvbE1tdJGdwREgE0SeKRACkRAQJikQBRU4WDgkwEeRTGfQd39zSt1P/20Zmb/nLOWQc2WWv2nHo36cjm3DQAAAAAAAKDD7dkOAAAAAAAAwJtBJwkAAAAAAAA96CQBAAAAAACgB50kAAAAAAAA9KCTBAAAAAAAgB50kgAAAAAAANCDThIAAAAAAAB60EkCAAAAAABADzpJAAAAAAAA6EEnCQAAAAAAAD3oJAEAAAAAAKAHnSQAAAAAAAD0WOkkb7fb7VYs3MsI+WFKa77Plg7cco4E1VpiemvGctBVAAAAAACAE3mJTtLs+srebF4r3NCmW8KlkyIDjqRvHQAAAAAA4AFc0kkO3VTY+ZRTs0KzSctmB8mFNsxs+Xz9c0StVQAAAAAAAE/h2k6ylM96y1BsaLfmLjQcn8VmnVpSeCv8dNSGLumsmq4CAAAAAABcx3onWXZow4ivalarx0OdZhShJ84SX7LrwyxwH/cTCwAAAAAAcB0n/zvJsjPM+jfH4qxEt17aerZ2LSjT4VBgsK4dE0YBAAAAAAAew+X/71YhPHdETi+3GU1X1qQJybL38+OaZ7WfpfJuRJlXAAAAAAAAp/CgTjLrhcxezhnJBjOHhVgWYNnLaW+FoUzAlB/shl4BAAAAAACcxSP+4o45KNok0TdqsdtEudyMSwgPgZSSpdo5iiwoAAAAAACAB/DQfydZqnL6rlKt2SJ2O8nQ1WWxIQrH1Tn2UhsAAAAAAMAVnNBJli2Z2Unen8sWMVzl+xOOZIPLGm4ToXBIqVa4lIUAAAAAAABwFlbXIXqesP8x+7Q1DZme+afws9WGtcLJVM3WQ1sCM0sAAAAAAABXQx8CAAAAAAAAPegkAQAAAAAAoAedJAAAAAAAAPSgkwQAAAAAAIAedJIAAAAAAADQg04SAAAAAAAAetBJAgAAAAAAQA86SQAAAAAAAOhBJwkAAAAAAAA96CQBAAAAAACgB50kAAAAAAAA9KCTBAAAAAAAgB50kgAAAAAAANCDThIAAAAAAAB60EkCAAAAAABADzpJAAAAAAAA6EEnCQAAAAAAAD3oJAEAAAAAAKDHm3WSt1vh8F5ACN/+x/55P7jsgGl9YfndW9OBZ3HWHt0Fyk15HY7HPldjyCxf+pBVlHCvfDWcESdAvQQAAAAAXpA3u8OdeFPPxMrLtHm3Fq7uZXST0NX8Cpy4Ry8e6czx2ENhs5K1Wr/qbsn/ZrE8Etp6l3oGAAAAgJA3u8PpS+f9Bly2fE7DVpor3Svv9L5CEVTZjDkJ2WQL0QrhrD3apr2YJR8We6nh9Ni3zeq1dNKOSDryC9bFAwAAAAC8EW92h3Nu6o7w0KLoqYWrf+aA040ccdiUWeum9HLtj+mYEA6fHxa7uVmnxJ7VW1g2+1RkkvfQ9g9lKYZZEq6WQZV+AgAAAMAb8bQ73K+//vrLL7/89ddfrVX6Su3c1GcN4l5bXotPHBRorxwT4c9Z5zyeaRYyp++R2JeHxW5u2fHYtyi6LPbQXPaQBS5i0SPCq1ZQ3dcBAAAAAF6BJ9zh/vnnn++///6/G+fXX3/922+/+Wv15TvrQEQr0jInmg2hMOsoTD+FsDAtLv1hIFmzkan1451NmHsUeui4cUXsawUzm3BiFw8iuvKh9GFQu7Y7YXrNMAEAAADgjXjCHe6nn37aXyu//fZbf215Uy8lt93VdktuzLNaff/WYvep2br2NgtnXqujCJeEeZvT6PgjxOZxU8k2JSpc+MjYM/3C1jDeTaCOffsyRWKVDq3rwKxTbE02buYTAAAAAF6WJ9zhfvzxx/0l8quvvvLXlr2HKWbe7LML9LLAfP8WN3LRP2gfTDdmu6LlcIyWU7MtLea0K11X1zpJbaIcd9wWYvtiCIskbM9E4JlkVnVZnZvvkdAwD5pbAAAAAADP5QmXtp9//nl/hf3uu+/8tWb7oe/KoR6nJ9mMS7PTxsxKsj5h/6wjWnAjexZX/NABbTqc1Xs0eCLalcfEXpooxwcTa7GHpTKnIkuOSJrOiY5LZzsMSkiKugIAAACAl+IJl7Z///33hx9++O/K+M033/zxxx/+WuemrsfDG62+0/sOzAK61Qlv6nqwa6L8udZN+a2FObuWgXfsJMtxUYT7qczh0orTx85LhM6yP9x7rq0DAAAAwLvwtDvcn3/++fvvv//999+tVf5NfX9tdfSYN/JuqyCUtK7v13WS2rGMUzrJbI+yDMy9x8NibynJMOtTN2alJ04n6Vh0ys/pJP13UAgDAAAAwKvxZpe2ViMnbqULnWTZZekb9oKk6KP2DdUV3VTYtjka9FToSSulw/MjY9cJ0cozT7q5DZWYy/dJ02HOeloCJlnsC6oAAAAA4PG89KUta5/KS/CgIdSs9Wf+CFeXhR1zL3u9vm6PQuGX4qLYs4o1hctk6iW35H+eGBwQAmHsQkYUAAAAAAC8LFzgAAAAAAAAoAedJAAAAAAAAPSgkwQAAAAAAIAedJIAAAAAAADQg07yQsq/I6L/HEs2Jf6kivmnXxzfQpnsz7F0XfVlxB9uWda5rWbetO5zlp9rCvWSVuwL+34dL+UMAAAAwEeFO9aFPL6TXPipe06xqnRAuHpE5vSGaqGTNN0oOb2TLMXmHex2kvPU2r5fyr6Mz9qpu86WwqenAgAAAOAi3uaWs9w/xP96Lmmc9kuOGHV8vptwejnHf32/L2//ZRSl9WFQROSE05LMfBazjk4tqa04HPezTNEgPJvOfDBjnwfPTdEyZYDLqloKnS0GAAAAeEfe4B7jX0lDmVvUGwzKQ4uZwnK59sd0TIybktnP5Yt+2IeIWS2/MGVmTE+ZekSKTrz9n1Ih2VS5R05z2NUZjjyXEzvJBYV0kgAAAPBReZt7zHWd5Jbfhp1boL7fZ5fycCTTMKsK1QoZ05wOVncIrY5izUk/hOOZHwLZq+qmTnCWn+GsUKi3cj9exm7ue6ht8C1UtdcQWp8XloTxZsxrQ3N6SSgciq05CQAAAPB43ua+4lytQpn5kjf/DK+w2ujtyytyy+fbdKsW993MQ/2sf+7vxNp6Kaz1l6kop5wU+TrLqMOgbtFeCOs+Z/k5qwo1D4GYPsw/F/ZdT2n54TkzLaLQIyVhEoTnYq0pvOYnAAAAwCN5m8uKc686cuEW92btjHDMvKM7SpwLtN9aOJlp2dqm5N9HBvlsj8It8yMSbs/j/n1dVMUpF/2z/JxlxG6aaTRj9/ddeDsPloXXisKRFDgFkFWFH+ZxPwEAAAAeydtcVro36Www+ynuzS2Fvs/ObXLviW66SsfEbVg3CaFCfWN2GonZRHkLf3Dmtyj525SWI5zl57CkbKv8cipjN/e9LJjBgbLwhOc6G4OGeVWmZ1AYOnAkzEwGAAAA4DV5m8uKc68St0nnZ3iNDhU6t9jS5+w+OiicL53CZ00W2jDS0p9JOqnYW/RTXaY9MzfMOjpDK+GItni1n6ZOvQvzuBm7M2tO6UGtMAzh/jAv9HdtWLv/ZyapHc6i0MkEAAAAeCne5rLSujiKQfPqJi6LvmNOn1COD1755syfBy/0C7P3ke692b9bH8/87N59xGw4H+NnONVa6GyNjl2r0lNlWWbPZcIdzSbHO8lumGt+AgAAADySt7msmM1JudC8rj24k8yu6bMS0bQsdJKt+/pZneS+LcmcuYuVbBGnZH7wdnZVh+xwop+OP/7gfaqM3dx3p8Xam3MKb60N25swdy0rVOeVWQ5zraIAAAAAHsYbXFayzkFcW8WgeePcX9x132Le7B3HSv3iElxe4oV8KBCKhYSzoQ+lXZHnzMMFSTPz86ospcuX/rP8DKecIil9mFXNsXf3fZ66rxV1EuoJC0aHOdiVccdry4rNIpoH5/FQBgAAAOAFeePLyqvdtG4ee/lQwzwopsS9s7QlfppKHElxXxfxliZmPadnXrO85Fw/Szf2AqFkNwqh09z3S9H18xSXAAAAAD4k73qv4kYIAAAAAADwLOjHAAAAAAAAoAedJAAAAAAAAPSgkwQAAAAAAIAedJIXUv7HnPrPqwhV/p+lcf6D0uf+R6fz3265yb9duRfL/lxN90/LhH/bRgiLP5Nj6hcCZ1XCssApNVP6ecW++4RKTLWtDSrl1wRO1+kHddz0Fu31QbVrWwnQIiwks7qE2FCoZemar1hXraN87RXjBQT4wPB6X0jrbtQ62cOR8GR3zvqnn/K33bXy7kzprU5LloEsG+HP0AdnO44IHKyErvU5n2Z1OfWm6/CKfV+jpeF4Pq/W6VR7uXHCPbFHojbMiPYPDpknIj8Ay+h61gvLqduXh2G2ynkXZiWh2u5bdtsdF34GeB8BPjBv8HqXl4a9pF5u3kXug5nFUoPwZ5h1Du5hvHS+fA7dKMMUAuXCLMyut9uXn8BsyvkZurp3WFgRUWifxayTH51V4V6m9hblPAxZBzjLhJpL5cLQQfc05QY5ycz8DB9O3yMRi+lhpvMWFVsYvtYQ/gyVO0FpTE/ugwdpOZatCse1ZMvDBVVOFJnPt6TaxWCZDVObH5QYnO0Oz47+eYmYDcWyDAj3hMNC3hGYZQbPhylzFwDgrXn193k+nnxhR0N2KJvnvqblrXlwhyP35/mwzg76TLnp4ZA38UXRekK3sw+PKaZ9OL53ZYAtbfPs8UrIlGjPW/kUyrO9K8WO7/sareWlxTDS+8LS7vIe7U3c8sLQPi/MDpLOBonAzZw4nvjjC/viLJk1ZKuyfQxXLTuzoCoj1BNWXWZR2NXZyDwpQ2tZcbTNOFWnq6t8f2cnQ2/v4/sXsHwlZ7tzikq02yIJAPCmvNn7rA8gfUaLn9kB6nwYtD/i4DbP1vJw156LQOZDv3Qpk9R

一、使用servlet时的实现方式，servlet的实现方式需要引入commons-fileupload-1.3.1.jar包。主要是用来解析前台传过来的请求。

　　1、前台页面的写法，当然要引入xheditor啦，这里我就不写了。这里主要是upImgUrl要写上你后台的Servlet。

<textarea class="editor" name="articleContent" rows="35" cols="100" style="z-index:99;"
        upImgUrl="UploadFileServlet" upImgExt="jpg,jpeg,gif,png" >
    ${article.articlecontent }
</textarea>

2、后台servlet的写法。配置文件中我也省略了，这里仅仅是一个Servlet。需要注意的，这里要引入commons-fileupload-1.3.1.jar包来解析请求。

package com.zk.web.action;

import java.io.File;
import java.io.IOException;
import java.util.Iterator;
import java.util.List;

import javax.servlet.ServletConfig;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;

public class UploadFileServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;
    private ServletContext sc;

    public void init(ServletConfig config) {
        sc = config.getServletContext();
    }

    protected void doGet(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {
        this.doPost(request, response);
    }

    protected void doPost(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {
        ServletOutputStream out = response.getOutputStream();
        request.setCharacterEncoding( "utf-8" );
        response.setHeader("Content-Type" , "text/html");
        String returnPath = "";

        DiskFileItemFactory factory = new DiskFileItemFactory();
        ServletFileUpload upload = new ServletFileUpload(factory);
        try {
            List items = upload.parseRequest(request);
            Iterator iter = items.iterator();
            while (iter.hasNext()) {
                FileItem item = (FileItem) iter.next();
                    System.out.println("上传文件的大小:" + item.getSize());
                    System.out.println("上传文件的类型:" + item.getContentType());
                    System.out.println("上传文件的名称:" + item.getName());

                    returnPath = "images/"+item.getName();
                    //这里是取得项目地址
                    File forder = new File(sc.getRealPath("/")+"images/");
　　　　　　　　　　　　//判断文件夹是否存在
                    if (!forder.exists()) {
                        forder.mkdir();
                    }

                    File file = new File(sc.getRealPath("/")+"images/"+item.getName());
                    item.write(file);
                    System.out.println("上传文件成功！");
            }
        } catch (Exception e) {
            e.printStackTrace();
            System.out.println("上传文件失败");
        }

        //这里是关键，返回上传图片存储在服务器的地址。路径根据自己项目的路径调整。
        out.print("{'err':'','msg':'"+ returnPath.replace("\\", "/")+"'}");

    }

}

二、使用spring mvc时的实现方式。uploadImage就是一个Action，

　　1、前台页面的写法，同样要引入xheditor啦，我也省略了，这里主要是upImgUrl要写上你后台的Action。

<textarea class="editor" name="articleContent" rows="35" cols="100" style="z-index:99;"
        upImgUrl="uploadImage.do" upImgExt="jpg,jpeg,gif,png" >
    ${article.articlecontent }
</textarea>

2、后台Action的写法，这里是使用的是sping mvc框架。

/**
     * 文本编辑器上传图片
     * @param request
     * @param response
     * @return
     * @throws Exception
     */
    public void uploadImage(HttpServletRequest request,
            HttpServletResponse response)throws Exception{
        ServletOutputStream out = response.getOutputStream();
        request.setCharacterEncoding( "utf-8" );
        response.setHeader("Content-Type" , "text/html");

        CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver(
                request.getSession().getServletContext());
        // 设置编码
        commonsMultipartResolver.setDefaultEncoding("utf-8");
        if (commonsMultipartResolver.isMultipart(request)) {
            MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
            MultipartFile image = multipartRequest.getFile("filedata");
            String url = "images"+File.separator+Tool.dateToString(new Date(), "yyyyMMdd")+File.separator;
　　　　　　　//这里可以从项目中取得你项目根目录的地址
            String filePath = "D:/"+url;
            Random r = new Random();
            if(image != null && !image.isEmpty()){
                InputStream xtins = image.getInputStream();
                String hj = new String(image.getOriginalFilename().getBytes("ISO-8859-1"),"UTF-8");
                hj = hj.split("\\.")[1];
　　　　　　　　　 //这里用来生成文件名
                String fileName = Tool.dateToString(new Date(), "yyyyMMddHHmmss")+r.nextInt(1000)+"."+hj;
                saveInputStreamToFile(filePath, fileName, xtins);
　　　　　　　　　 //这里是用来返回给xheditor的
                out.print("{'err':'','msg':'"+ (url+fileName).replace("\\", "/")+"'}");
            }
        }
    }

    /**
     * 保存文件流到指定路径
     * @param filePath
     * @param fileName
     * @param inputStream
     * @throws Exception
     */
    public void saveInputStreamToFile(String filePath, String fileName,
            InputStream inputStream) throws Exception {
        OutputStream os = null;
        try {
            File forder = new File(filePath);
            if (!forder.exists()) {
                forder.mkdir();
            }
            File file = new File(filePath + fileName);
            os = new FileOutputStream(file);
            int bytesRead = 0;
            byte[] buffer = new byte[8192];
            while ((bytesRead = inputStream.read(buffer, 0, 8192)) != -1) {
                os.write(buffer, 0, bytesRead);
            }
            os.close();
            inputStream.close();
        } catch (Exception ex) {
            ex.printStackTrace();
            throw ex;
        } finally {
            if (inputStream != null) {
                inputStream.close();
            }
            if (os != null) {
                os.close();
            }
        }
    }
