百度UEditor富文本上传图片

项目中使用UEditor发现设置图片自定义保存路径会出现《请求后台配置项http错误，上传功能将不能正常使用！错误》

 /* 上传图片配置项 */
    "imageActionName": "uploadimage", /* 执行上传图片的action名称 */
    "imageFieldName": "inputForm", /* 提交的图片表单名称 */
    "imageMaxSize": , /* 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": , /* 图片压缩最长边限制 */
    "imageInsertAlign": "none", /* 插入的图片浮动方式 */
    "imageUrlPrefix": "/cms/static/userfiles/", /* 图片访问路径前缀 */
    "imagePathFormat": "/{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 */

原因在于UEditor提供的 ueditor-1.1.2.jar 之中的 ConfigManager 类获取不到 config.json 文件

上传图片会获取controller.jsp地址

 //ueditor.config.js

var URL = window.UEDITOR_HOME_URL || getUEBasePath();
    /**
     * 配置项主体。注意，此处所有涉及到路径的配置别遗漏URL变量。
     */
    window.UEDITOR_CONFIG = {

        //为编辑器实例添加一个路径，这个不能被注释
        UEDITOR_HOME_URL: URL

        // 服务器统一请求接口路径
        , serverUrl: URL + "jsp/controller.jsp"

执行controller.jsp，rootPath 是要保存图片的路径

//controller.jsp
<%

    request.setCharacterEncoding( "utf-8" );
    response.setHeader("Content-Type" , "text/html");

    String rootPath = application.getRealPath( "/" );
    out.write( new ActionEnter( request, rootPath ).exec() );

%>

修改后

<%

    request.setCharacterEncoding("utf-8");
    response.setHeader("Content-Type", "text/html");
//    String rootPath = application.getRealPath( "/" );
    String rootPath = Global.getConfig("userfiles.basedir");//图片保存目录，会与imagePathFormat拼接起来，此为主要保存路径，imagePathFormat可以只设置图片名称
    String jsonPath = Global.getConfig("userfiles.jsonPash"); //config.json 目录
    out.write(new ActionEnter(request, rootPath, jsonPath).exec());
%>

ActionEnter执行了 ConfigManager.getInstance 传入了 request.getRequestURI()

request.getRequestURI()获取的是 controller.jsp文件的相对路径

//ActionEnter类

public ActionEnter(HttpServletRequest request, String rootPath) {
        this.request = request;
        this.rootPath = rootPath;
        this.actionType = request.getParameter("action");
        this.contextPath = request.getContextPath();
        this.configManager = ConfigManager.getInstance(this.rootPath, this.contextPath, request.getRequestURI());
    }

修改后

 public ActionEnter(HttpServletRequest request, String rootPath, String jsonPath) {
        this.request = request;
        this.rootPath = rootPath;
        this.actionType = request.getParameter("action");
        this.contextPath = request.getContextPath();
        this.configManager = ConfigManager.getInstance(this.rootPath, this.contextPath, jsonPath);
    }

此时 ConfigManager 方法用你的图片保存路径加上 controller.jsp 的相对路径去找 config.json，就出现找不到的情况，可以修改jar包，把 request.getRequestURI()更改为变量，以传参方式把地址传进来，再把if去掉，直接使用传 uri 给 File

//ConfigManager类

public final class ConfigManager {
    private final String rootPath;
    private final String originalPath;
    private final String contextPath;
    private static final String configFileName = "config.json";
    private String parentPath = null;
    private JSONObject jsonConfig = null;
    private static final String SCRAWL_FILE_NAME = "scrawl";
    private static final String REMOTE_FILE_NAME = "remote";
　　
    private ConfigManager(String rootPath, String contextPath, String uri) throws FileNotFoundException, IOException {
        rootPath = rootPath.replace("\\", "/");
        this.rootPath = rootPath;
        this.contextPath = contextPath;
        if (contextPath.length() > ) {
            this.originalPath = this.rootPath + uri.substring(contextPath.length());
        } else {
            this.originalPath = this.rootPath + uri;
        }

        this.initEnv();
    }

    public static ConfigManager getInstance(String rootPath, String contextPath, String uri) {
        try {
            return new ConfigManager(rootPath, contextPath, uri);
        } catch (Exception var4) {
            return null;
        }
    }
　　//获取 config.json
    private void initEnv() throws FileNotFoundException, IOException {
        File file = new File(this.originalPath);
        if (!file.isAbsolute()) {
            file = new File(file.getAbsolutePath());
        }

        this.parentPath = file.getParent();
        String configContent = this.readFile(this.getConfigPath());

        try {
            JSONObject jsonConfig = new JSONObject(configContent);
            this.jsonConfig = jsonConfig;
        } catch (Exception var4) {
            this.jsonConfig = null;
        }

    }
　　//获取 config.json 路径
    private String getConfigPath() {
        return this.parentPath + File.separator + "config.json";
    }
}

修改后

private ConfigManager(String rootPath, String contextPath, String jsonPath) throws FileNotFoundException, IOException {
        rootPath = rootPath.replace("\\", "/");
        this.rootPath = rootPath;
        this.contextPath = contextPath;
        this.originalPath = jsonPath;
        this.initEnv();
    }
