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": 1024000, /* 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": "/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() > 0) { 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(); }
图片上传成功
