UEditor使用细节注意

原理：先加载配置，后上传，最后回显。

UEditor给出了controller.jsp来进行加载配置，并上传，但是这些不是我们想要的。我们需要重写加载配置和上传回显操作。

serverUrl是我们需要修改的地方，它的作用是让我们加载配置。

这里我将serverUrl设置为：serverUrl: ROOT_PATH + "ueditor/upload"

upload方法（给出整段代码）：

import java.io.File;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.IOException;import java.io.OutputStream;import java.util.Map;import java.util.UUID;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.commons.io.IOUtils;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.multipart.commons.CommonsMultipartFile;import com.google.common.collect.Maps;@Controller@RequestMapping("/ueditor")public class UeditorController extends BasicController{@RequestMappingpublic String index(){System.out.println(1);return "/ueditor/index";}@RequestMapping(value = "/upload", method = RequestMethod.GET)      @ResponseBody      public void upload(HttpServletRequest request, HttpServletResponse response) throws IOException {          String action = request.getParameter("action");          if ("config".equals(action)) {              OutputStream os = response.getOutputStream();              IOUtils.copy(UeditorController.class.getClassLoader().getResourceAsStream("config.json"), os);          }    }        @RequestMapping(value = "/upload", method = RequestMethod.POST)      @ResponseBody      public Map<String, String> upload(HttpServletRequest request,@RequestParam CommonsMultipartFile upfile) throws IOException {      Map<String, String> result = Maps.newHashMap();    System.out.println(upfile.getFileItem().getFieldName());    String path = getFilePath(upfile);    File file = new File(path);    System.out.println(path);    String state = "SUCCESS";        //返回类型      String rootPath = request.getContextPath();    result.put("url", rootPath + "/ueditor/show?filePath=" + path);        result.put("size", String.valueOf(file.length()));          result.put("type", file.getName().substring(file.getName().lastIndexOf(".")));          result.put("state", state);          return result;      }        @RequestMapping(value = "/show", method = RequestMethod.GET)    public void show(String filePath, HttpServletResponse response) throws IOException {                File file = getFile(filePath);        response.setDateHeader("Expires", System.currentTimeMillis() + 1000 * 60 * 60 * 24);        response.setHeader("Cache-Control", "max-age=60");        OutputStream os = response.getOutputStream();        FileInputStream is = null;        try {            is = new FileInputStream(file);            IOUtils.copy(is, os);        } catch (FileNotFoundException e) {            response.setStatus(404);            return;        } finally {            if (null != is) {                is.close();            }            if (null != os) {                os.flush();                os.close();            }        }    }        protected String getFilePath(CommonsMultipartFile uploadFile){    String absolutePath = "D:/upload";    File folder = new File(absolutePath);        if (!folder.exists()) {            folder.mkdirs();        }        String rawName = uploadFile.getFileItem().getName();        String fileExt = rawName.substring(rawName.lastIndexOf("."));        String newName = System.currentTimeMillis() + UUID.randomUUID().toString() + fileExt;        File saveFile = new File(absolutePath + File.separator + newName);        try {            uploadFile.getFileItem().write(saveFile);        } catch (Exception e) {            e.printStackTrace();            return "";        }        return absolutePath + "/" + newName;    }        protected File getFile(String path){    File file = new File(path);    return file;        }    }

config.json，将这个配置放在resources里面。

需要注意的是，上传的那段代码，由于config.json中：
 "imageFieldName": "upfile", /* 提交的图片表单名称 */

iageFiledName给的是upfile，所以我这里要写upfile，不然就会出错。

其实只要我们好好的理解ActionEnter具体是怎么实现的就行。
