JsonConfig jsonConfig = new JsonConfig();
            
            jsonConfig.registerJsonValueProcessor(Date.class, new JsonDateValueProcessor()
                @Override
                public Object processArrayValue(Object obj, JsonConfig jsonconfig) 
                    return process(obj);
                
                @Override
                public Object processObjectValue(String s, Object obj, JsonConfig jsonconfig) 
                    return process(obj);
                
                private Object process(Object obj) 
                    if (obj == null) // 如果时间为null，则返回空字串 "yyyy-MM-dd hh:mm:ss"
                        return "";
                    
                    if (obj instanceof Date) 
                        obj = new java.util.Date(((Date) obj).getTime());
                    
                    if (obj instanceof java.util.Date) 
                        SimpleDateFormat sdf = new SimpleDateFormat(dateFomart,
                                Locale.CHINA);// 
                        return sdf.format(obj);
                     else 
                        return new Object();
                    
                
            );
            json = JSONObject.fromObject(javaObj , jsonConfig);
