前景：

net.sf.ezmorph.bean.MorphDynaBean cannot be cast to com.console.demo.web.model.XXX

//jsonObject:所有参数//FreightTemplate对象里面包含一个 private List
    
      freightTemplateCity; 类似于一父多子FreightTemplate freightTemplate = (FreightTemplate) JSONObject.toBean(JSONObject.fromObject(jsonObject.get("freightTemplate")), FreightTemplate.class);//先新增freightTemplatebusinessDao.insertSelective(freightTemplate);//取出子list对象List
     
       freightTemplateCities = freightTemplate.getFreightTemplateCity();//遍历新增子对象//PS:这句for循环报的错for (FreightTemplateCity freightTemplateCity : freightTemplateCities) {
       freightTemplateCity.setTemplateId(freightTemplate.getId());    businessDao.insertFreightTemplateCity(freightTemplateCity);}
     
    

发现我的子对象自动被转换成了net.sf.ezmorph.bean.MorphDynaBean对象，找了半天不知道哪里转成这个的，于是想到直接把

JSONObject object = (JSONObject) jsonObject.get("freightTemplate");//从所有对象里取到父对象，转成JSONObject类型JSONArray array = (JSONArray) object.get("freightTemplateCity");//从JSONObject里面取到"freightTemplateCity"转成JSONArray格式

然后JSONArray就可以直接转list了，下面贴代码

FreightTemplate freightTemplate = (FreightTemplate) JSONObject.toBean(JSONObject.fromObject(jsonObject.get("freightTemplate")), FreightTemplate.class);//先新增freightTemplatebusinessDao.insertSelective(freightTemplate);//------------这一段转换对象类型----------------JSONObject object = (JSONObject) jsonObject.get("freightTemplate");JSONArray array = (JSONArray) object.get("freightTemplateCity");List
    
      list = JSONArray.toList(array, new FreightTemplateCity(), new JsonConfig());//----------------------------for (FreightTemplateCity freightTemplateCity : list) {     freightTemplateCity.setTemplateId(freightTemplate.getId());     businessDao.insertFreightTemplateCity(freightTemplateCity);}
    

但是因为不知道具体发生转换的原因，不知道这样做有没有什么影响，如果有其他好的办法，望不吝啬指教一下
