//后台：

List tagListType = new ArrayList<>();
        OptionBean optionBean = new OptionBean();
        optionBean.setId("0");
        optionBean.setValue("油电混合");
        tagListType.add(optionBean);
        optionBean = new OptionBean();
        optionBean.setId("1");
        optionBean.setValue("汽油车");
        tagListType.add(optionBean);
        optionBean = new OptionBean();
        optionBean.setId("2");
        optionBean.setValue("纯电动");
        tagListType.add(optionBean);
        map.put("tagListType", tagListType);

结果：
