大家好，又见面了，我是你们的朋友全栈君。
多次试了下传入数组或者list json格式 感觉还是有问题。
后面用最傻的方法先把参数设置成String类型传入到后台再做转换
public Object saveScenceCheckDraw(CheckDrawings checkDrawings,String drawingImgList) {
GsonBuilder builder = new GsonBuilder();
builder.registerTypeAdapter(Date.class, new JsonDeserializer<Date>() {
public Date deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
return new Date(json.getAsJsonPrimitive().getAsLong());
}
});
Gson gson = builder.create();
Type collectionType= new TypeToken<List<CheckDrawingImg>>(){}.getType();
List<CheckDrawingImg> checkDrawingImg= gson.fromJson(drawingImgList,collectionType);
CheckDrawingImgList list=new CheckDrawingImgList();
list.setDrawingImgList(checkDrawingImg);
return null;
}
