vue+Java整合UEditor报错后台配置项返回格式出错，上传功能将不能正常使用！
java+ruoyi框架，Ueditor正常显示，但是在初始化的时候报错“后台配置项返回格式出错，上传功能将不能正常使用！”
后台能打印数据，能读取到config.json，没有报错，config.json中imageUrlPrefix等地址用的是IP地址

回答：
解决了，返回的json字符串格式不对，在前端ueditor加载的时候会读取到后端@RequestMapping("/ueditor/ueditorConfig")配置，根据if判断走的是
exec = new ActionEnter(request, rootPath).exec();这个方法，之前读取配置返回的参数错了
下面的代码三个if判断，上传图片、上传文件和读取配置
String exec = ""; String actionType = request.getParameter("action");
if("uploadimage".equals(actionType) && !upfile.isEmpty()){
// 做图片上传操作
exec = uploadImage(upfile);
}else if("uploadfile".equals(actionType)&&!upfile.isEmpty()){
exec =uploadFile(upfile);
}else{
request.setCharacterEncoding( "utf-8" );
exec = new ActionEnter(request, rootPath).exec();
}
看一下这个exec()方法和invoke()方法，当时打断点的时候invoke()方法中第一个if!ActionMap.mapping.containsKey(this.actionType))是true，直接返回了，说明这个map里面不包括这个actionType，这个actionType的值是"config"，但是ActionMap这个集合里面一个值都没有，肯定不对，应该没有初始化
public String exec() {
String callbackName = this.request.getParameter("callback");
if (callbackName != null)
{
if (!validCallbackName(callbackName)) {
return new BaseState(false, 401).toJSONString();
}
return callbackName + "(" + invoke() + ");";
}
return invoke();
}
public String invoke() {
if ((this.actionType == null) || (!ActionMap.mapping.containsKey(this.actionType))) {
return new BaseState(false, 101).toJSONString();
}
if ((this.configManager == null) || (!this.configManager.valid())) {
return new BaseState(false, 102).toJSONString();
}
State state = null;
int actionCode = ActionMap.getType(this.actionType);
Map<String, Object> conf = null;
switch (actionCode)
{
case 0:
return this.configManager.getAllConfig().toString();
case 1:
case 2:
case 3:
case 4:
conf = this.configManager.getConfig(actionCode);
state = new Uploader(this.request, conf).doExec();
break;
case 5:
conf = this.configManager.getConfig(actionCode);
String[] list = this.request.getParameterValues((String)conf.get("fieldName"));
state = new ImageHunter(conf).capture(list);
break;
case 6:
case 7:
conf = this.configManager.getConfig(actionCode);
int start = getStartIndex();
state = new FileManager(conf).listFile(start);
}
return state.toJSONString();
}
这个是原始文件
然后对文件进行了修改，actionType传过来的都是小写不带下划线，这里面原始参数都是大写，除了读取配置其它的功能都是自定义方法应该省略了。
public final class ActionMap{
public static final Map<String, Integer> mapping = new HashMap() {};
public static final int CONFIG = 0;
public static final int UPLOAD_IMAGE = 1;
public static final int UPLOAD_SCRAWL = 2;
public static final int UPLOAD_VIDEO = 3;
public static final int UPLOAD_FILE = 4;
public static final int CATCH_IMAGE = 5;
public static final int LIST_FILE = 6;
public static final int LIST_IMAGE = 7;
public static int getType(String key)
{
return ((Integer)mapping.get(key)).intValue();
}
static {
mapping.put("config",0);
mapping.put("uploadimage",1);
mapping.put("uploadscrawl",2);
mapping.put("uploadvideo",3);
mapping.put("uploadfile",4);
mapping.put("catchimage",5);
mapping.put("listfile",6);
mapping.put("listimage",7);
}
}
这个ActionMap等类都是从ueditor-1.1.2.jar包中反编译复制过来的，按理来说这种jar包不会错的，不知道是不是自己之前哪里配置错了
除了读取配置，上传图片和上传文件方法中返回的报文格式都是固定的
private String uploadFile(MultipartFile file) { JSONObject jsonResult = null;
try {
if(!checkFileSize(file,1,"M")){
jsonResult = new JSONObject(resultMap("文件大小超过1M", "", 0, "", "", ""));
return jsonResult.toString();
}
String fileName = file.getOriginalFilename();
String extraName = fileName.substring(fileName.lastIndexOf("."));
String filePath = RuoYiConfig.getUploadPath();
String fileName1 = FileUploadUtils.upload(filePath, file);
String url = serverConfig.getUrl() + fileName1;
jsonResult = new JSONObject(resultMap("SUCCESS", url, file.getSize(), fileName, fileName, extraName));
} catch (Exception e) {
logger.warn("UeditorController#uploadImage exception:", e);
jsonResult = new JSONObject(resultMap("文件上传失败", "", 0, "", "", ""));
}
return jsonResult.toString();
}
private String uploadImage(MultipartFile file) {
JSONObject jsonResult = null;
try {
if(!checkFileSize(file,1,"M")){
jsonResult = new JSONObject(resultMap("文件上传失败，文件大小超过1M", "", 0, "", "", ""));
return jsonResult.toString();
}
String fileName = file.getOriginalFilename();
String extraName = fileName.substring(fileName.lastIndexOf("."));
String filePath = RuoYiConfig.getUploadPath();
String fileName1 = FileUploadUtils.upload(filePath, file);
String url = serverConfig.getUrl() + fileName1;
jsonResult = new JSONObject(resultMap("SUCCESS", url, file.getSize(), fileName, fileName, extraName));
} catch (Exception e) {
logger.warn("UeditorController#uploadImage exception:", e);
jsonResult = new JSONObject(resultMap("文件上传失败", "", 0, "", "", ""));
}
return jsonResult.toString();
}
之后出现过跨域问题，但也是配置错了
我这边开始直接在方法上加了@CrossOrigin注解，但还是错了，后来看浏览器控制台报的跨域错误发现路径错了，config.json里的imageUrlPrefix这些url留空就行了，之前看网上其它帖子都会加localhost或者IP
