使用Thymeleaf形式与复合对象（内部有2个对象）

Question

问题

我正在使用Thymeleaf模板引擎的Spring-boot，我在页面中有一个表单，它需要更新2个实体但它们具有相同的属性，所以我将2个实体混合成1个复杂对象，但是当请求时我的控制器，它发生了JSON解析错误，请帮我弄清楚发生了什么事。

用于调试的控制器

    @RequestMapping(value = "shop", method = RequestMethod.POST)
    public String createShop(@RequestBody String json , final Locale locale,
            Model model, HttpSession session) {

        ObjectMapper om = new ObjectMapper();
        try {
            om.readValue(json, CreateShopForm.class);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        model.addAttribute(H2S_LAYOUT_PAGE_TITLE, messageSource.getMessage("cms.common.sidebar.profile", null, locale));
        model.addAttribute(H2S_LAYOUT_PAGE_DESC, "建立商家資料完成");
        model.addAttribute(H2S_LAYOUT_CONTENT, "modules/admin/register_success");

        return "layouts/admin";
    }

复杂对象

public class CreateShopForm{
    private Employee employee;
    private Shop shop;
    public Employee getEmployee() {
        return employee;
    }
    public void setEmployee(Employee employee) {
        this.employee = employee;
    }
    public Shop getShop() {
        return shop;
    }
    public void setShop(Shop shop) {
        this.shop = shop;
    }
}

带有Thymeleaf标签的HTML

<form enctype='application/json' th:action="@{/admin/shop}" method="post" class="form-horizontal"
  role="form" id="shop-profile-form" th:object="${createShopForm}">

  <h2 class="header smaller lighter blue">公司資料：</h2>

<!--   <div class="form-group has-error"> -->
  <div class="form-group">
    <label class="col-sm-2 col-xs-12 control-label no-padding-right">公司登記名稱</label>
    <div class="col-sm-5 col-xs-12">
      <input type="text" class="col-xs-12"
        th:field="*{shop.registrationName}" />
    </div>
<!--     <div class="help-block col-sm-5 col-xs-12 col-sm-reset inline">
      欄位必填!</div> -->
  </div>

  <div class="form-group">
    <label class="col-sm-2 col-xs-12 control-label no-padding-right">公司統一編號</label>
    <div class="col-sm-5 col-xs-12">
      <input type="text" class="col-xs-12" th:field="*{employee.taxNumber}" />
    </div>
  </div>
</form>

异常
