百度UEditor自定义上传文件存储路径

这是基于SSM项目中，使用freemaker加UEditor富文本编辑器修改的，不过使用与JSP的UEditor大同小异，修改后的功能是可以配置上传图片、文件、涂鸦等的存储路径，而不是默认地存储在项目路径下。

首先，增加ueditor.properties配置文件，内容为：

#上传文件存储路径
ueditor.imagePath=F:/jblog/

修改UEditorController，如果是使用JSP页面的，对应修改controller.jsp：

原本的UEditorController为：

@Controller
@RequestMapping("/static/ueditor")
public class UEditorController {

@RequestMapping("/jsp/controller")
public void writePage(HttpServletRequest request, HttpServletResponse response)
throws IOException {
request.setCharacterEncoding( "utf-8" );
response.setHeader("Content-Type" , "text/html");

String rootPath = request.getSession().getServletContext().getRealPath("/");
response.getWriter().write(new ActionEnter(request, rootPath).exec());
}
}

修改后：

@Controller
@RequestMapping("/static/ueditor")
public class UEditorController {

private static String saveRootPath;

static {
try {
Properties prop = new Properties();
InputStream inStream = (new DefaultResourceLoader()).getResource("classpath:ueditor.properties").getInputStream();
prop.load(inStream);
saveRootPath = prop.getProperty("ueditor.imagePath");
} catch (Exception e) {
throw new RuntimeException("从ueditor.properties配置文件中获取ueditor图片存储位置失败", e);
}
}

@RequestMapping("/jsp/controller")
public void writePage(HttpServletRequest request, HttpServletResponse response)
throws IOException {
request.setCharacterEncoding( "utf-8" );
response.setHeader("Content-Type" , "text/html");
String rootPath = request.getSession().getServletContext().getRealPath("/");
response.getWriter().write(new ActionEnter(request, rootPath, saveRootPath).exec());
}
}

此时，会发现

new ActionEnter(request, rootPath, saveRootPath)

报错，是因为ActionEnter构造器只有两个参数的，这里需要修改ueditor.jar中的类。

修改ConfigManager类：

//增加字段saveRootPath
...
private String saveRoot
4000
Path = null;
...
//构造器增加参数saveRootPath，
//并在构造器中对saveRootPath赋值
private ConfigManager(String rootPath, String contextPath, String saveRootPath, String uri) throws FileNotFoundException, IOException {
rootPath = rootPath.replace("\\", "/");
this.saveRootPath = saveRootPath;
this.rootPath = rootPath;
this.contextPath = contextPath;
if (contextPath.length() > 0) {
this.originalPath = this.rootPath + uri.substring(contextPath.length());
} else {
this.originalPath = this.rootPath + uri;
}

this.initEnv();
}
//getInstance方法参数saveRootPath，调用修改后的构造器
public static ConfigManager getInstance(String rootPath, String contextPath, String saveRootPath, String uri) {
try {
return new ConfigManager(rootPath, contextPath, saveRootPath, uri);
} catch (Exception var4) {
return null;
}
}
...
//把saveRootPath设置到config中
public Map<String, Object> getConfig(int type) {
Map<String, Object> conf = new HashMap();
String savePath = null;
...
conf.put("savePath", savePath);
conf.put("rootPath", this.rootPath);
conf.put("saveRootPath", this.saveRootPath);
return conf;
}

修改ActionEnter类：

...
//增加字段saveRootPath
private String saveRootPath = null;
...
//修改ActionEnter构造器，调用修改后的ConfigManager.getInstance方法
public ActionEnter(HttpServletRequest request, String rootPath, String saveRootPath) {
this.request = request;
this.rootPath = rootPath;
this.saveRootPath = saveRootPath;
this.actionType = request.getParameter("action");
this.contextPath = request.getContextPath();
this.configManager = ConfigManager.getInstance(this.rootPath, this.contextPath, this.saveRootPath, request.getRequestURI());
}

修改BinaryUploader类：

public class BinaryUploader {
public BinaryUploader() {
}

public static final State save(HttpServletRequest request, Map<String, Object> conf) {
try {
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest)request;
MultipartFile multipartFile = multipartRequest.getFile(conf.get("fieldName").toString());
String savePath = (String)conf.get("savePath");
String originFileName = multipartFile.getOriginalFilename();
String suffix = FileType.getSuffixByFilename(originFileName);
originFileName = originFileName.substring(0, originFileName.length() - suffix.length());
savePath = savePath + suffix;
long maxSize = ((Long)conf.get("maxSize")).longValue();
if (!validType(suffix, (String[])((String[])conf.get("allowFiles")))) {
return new BaseState(false, 8);
} else {
savePath = PathFormat.parse(savePath, originFileName);
int index = savePath.lastIndexOf('/');
String saveRootPath = (String)conf.get("saveRootPath");
String physicalPath = saveRootPath + savePath.substring(0, index);
File targetFile = new File(physicalPath);
if (!targetFile.exists()) {
targetFile.mkdirs();
}

State storageState = StorageManager.saveFileByInputStream(multipartFile.getInputStream(), saveRootPath + savePath, maxSize);
if (storageState.isSuccess()) {
storageState.putInfo("url", PathFormat.format(savePath));
storageState.putInfo("type", suffix);
storageState.putInfo("original", originFileName + suffix);
}

return storageState;
}
} catch (Exception e) {
e.printStackTrace();
System.out.println(e.getMessage());
return new BaseState(false, 4);
}
}

private static boolean validType(String type, String[] allowTypes) {
List<String> list = Arrays.asList(allowTypes);
return list.contains(type);
}
}

到这里完成了对图片、视频、文件的存储路径的修改，如果需要用到涂鸦的功能，还需要修改Base64Uploader类：

public static State save(String content, Map<String, Object> conf) {
byte[] data = decode(content);
long maxSize = ((Long)conf.get("maxSize")).longValue();
if (!validSize(data, maxSize)) {
return new BaseState(false, 1);
} else {
String suffix = FileType.getSuffix("JPG");
String savePath = PathFormat.parse((String)conf.get("savePath"), (String)conf.get("filename"));
savePath = savePath + suffix;
String physicalPath = (String)conf.get("saveRootPath") + savePath;
State storageState = StorageManager.saveBinaryFile(data, physicalPath);
if (storageState.isSuccess()) {
storageState.putInfo("url", PathFormat.format(savePath));
storageState.putInfo("type", suffix);
storageState.putInfo("original", "");
}

return storageState;
}
}

完成了上传文件的存储设置后，图片还不能回显，在spring mvc配置文件中增加配置：

<context:property-placeholder location="classpath:ueditor.properties" />
<mvc:resources  mapping="/ueditor/upload/**" location= "file:${ueditor.imagePath}/ueditor/upload/" />

也可以写一个handle处理文件请求，参考：http://blog.csdn.net/yuancenyi/article/details/53327414

配置文件config.json内容为：

/* 上传图片配置项 */
"imageActionName": "uploadimage", /* 执行上传图片的action名称 */
"imageFieldName": "upfile", /* 提交的图片表单名称 */
"imageMaxSize": 2048000, /* 上传大小限制，单位B */
"imageAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"], /* 上传图片格式显示 */
"imageCompressEnable": true, /* 是否压缩图片,默认是true */
"imageCompressBorder": 1600, /* 图片压缩最长边限制 */
"imageInsertAlign": "none", /* 插入的图片浮动方式 */
"imageUrlPrefix": "/admin", /* 图片访问路径前缀 */
"imagePathFormat": "/ueditor/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}"
......

修改后的效果为：







还有其中截图功能不能使用的问题尚未解决



点击截图后，提示需要安装截图插件，安装完成后点击截图依旧出现该界面，再火狐，谷歌，还有Windows10自带的浏览器都是如此，只有IE可以调用出截图功能，可是会出现错误：

看起来是流中断了，此问题未能解决。
