SSM整合项目中使用百度Ueditor遇到的问题。

问题描述：无法上传图片，提示配置项加载有问题

大致情形：直接下载的ue编辑器，放在了/resources/ 目录下，也就是静态资源路径，然后更改web.xml，将tomcat默认拦截器配置放到所有servlet的最上面

1     <!-- 不拦截静态文件 -->  
2     <servlet-mapping>  
3         <servlet-name>default</servlet-name>  
4         <url-pattern>/resources/*</url-pattern>  
5     </servlet-mapping>

可即使是这样，打开demo界面，点图片上传，提示后端配置未正常加载，手动输入百度ue的controller.jsp地址时却输出的是controller.jsp的源码，不放弃，继续：

查看官方文档得知默认会访问controller.jsp是因为如下配置项（ps:图是改过后的，非默认配置），既然这样，那咱们就自己定义个controller，把controller.jsp的代码copy到自己的controller里面，然后更改图中配置项来处理ue的请求：

说做就做：

 1 package **********************************;
 2 
 3 import javax.servlet.http.HttpServletRequest;
 4 import javax.servlet.http.HttpServletResponse;
 5 
 6 import org.springframework.stereotype.Controller;
 7 import org.springframework.web.bind.annotation.RequestMapping;
 8 import org.springframework.web.bind.annotation.RequestParam;
 9 
10 import com.baidu.ueditor.ActionEnter;
11 
12 @Controller
13 @RequestMapping("/ueditor")
14 public class UeditorController {
15 
16     @RequestMapping("/upload")
17     public void exec(@RequestParam(value="action",required=false)String action,
18             @RequestParam(value="callback",required=false)String callback,
19             HttpServletRequest req, HttpServletResponse res) {
20         try {
21             req.setCharacterEncoding("utf-8");
22             res.setHeader("Content-Type", "text/html");
23             String rootPath =req.getSession().getServletContext().getRealPath("/");
24             res.getWriter().write(new ActionEnter(req, rootPath,"").exec());
25         } catch (Exception e) {
26             e.printStackTrace();
27         }
28     }
29 }

这下应该可以了吧，no,no,no,还是提示后端服务为正常加载，debug模式走起，原来百度ue有个小问题，归纳起来如下：

首先肯定要加载所有配置，java语言的配置是在config.json中配置的，然后引申出另一个问题，如何获取config.json的真实路径，

原来百度的大神们是这样做的：假设你们可以访问到ue的初始页面，也就是可以看到编辑框，那么ue在编辑框初始化的时候就发个询问后端配置是否正常的get请求，就是ueditor.config.js中配置的serverUrl，然后加个参数 ?action=config，代码里最后走这行代码：

1 res.getWriter().write(new ActionEnter(req, rootPath,"").exec());

rootpath是项目的真实物理路径，而后用request.getRequestURI获取访问路径，两者加到一起，就获取到了config.json文件所在路径的文件夹（假设还是访问的controller.jsp，那么是没问题的.ps:一改问题就多。。。）,这样就可以加载config.json文件中的所有配置了。然而spring mvc可随意定义url路径，所以，这样做就有问题了，所以就出了上面那个配置项有问题无法上传的提示了。那怎么解决呢？在我走了一段弯路之后怒了，大爷的不就是要加载config.json吗？何必绕那么大的圈子，我直接给你不就完了？于是乎,下载ue的jar包源码，更改ActionEnter的构造方法，将路径传过去，最后的ActionEnter如下：

终于成功了，

以为终于可以结束了，然而并不是，点击上传图片老提示没有发现上传的数据，再次debug源码，spring mvc对request进行了包装，导致无法获取上传数据，无语了，那就直接换servlet处理，上代码：

32         String jsonFilePath=rootPath+"/resources/ueditor/jsp/config.json";

终于要结束了吗？no，前端无法显示图片，无法在线管理，原来图片上传时保存的路径是在config.json中的

1  "imagePathFormat": "/resources/ueditor/jsp/upload/image/{yyyy}{MM}{dd}/{time}{rand:6}", /* 上传保存路径,可以自定义保存路径和文件名格式 */

而列出路径是这样的：

1 "imageManagerListPath": "/ueditor/jsp/upload/image/", /* 指定要列出图片的目录 */

这样上面保存图片时分日期保存的，然后参照列出路径列出的是目录，那肯定不行的，于是乎干掉imagePathFormat的日期，也就是{yyyy}{MM}{dd},变成这样：

1  "imagePathFormat": "/resources/ueditor/jsp/upload/image/{time}{rand:6}", /* 上传保存路径,可以自定义保存路径和文件名格式 */

改好后还是不行，原因是fileManagerUrlPrefix，imageManagerUrlPrefix配置有问题，最后改成这样终于正常了：

最后在给个github ue的url：https://github.com/fex-team/ueditor，将ActionEnter和ConfigManager替换并导出的jar替换官方的jar即可按照图中所述的方式使用了。
