Spring Thymeleaf对象绑定列表
这是我从数据库中检索到的对象:Spring Thymeleaf对象绑定列表,spring,forms,spring-mvc,thymeleaf,Spring,Forms,Spring Mvc,Thymeleaf,这是我从数据库中检索到的对象: @RequestMapping("/category/edit/{id}") @org.springframework.transaction.annotation.Transactional public ModelAndView displayCategoryList(@PathVariable("id")Integer id){ ModelAndView mav = new ModelAndView("category-form"); Lis
@RequestMapping("/category/edit/{id}")
@org.springframework.transaction.annotation.Transactional
public ModelAndView displayCategoryList(@PathVariable("id")Integer id){
ModelAndView mav = new ModelAndView("category-form");
List<CatFeatGroup> catFeatGroupList = catFeatGroupService.findGroupsForCategory(id);
mav.addObject("catFeatGroupList",catFeatGroupList);
return mav;
}
@RequestMapping(“/category/edit/{id}”)
@org.springframework.transaction.annotation.Transactional
公共ModelAndView displayCategoryList(@PathVariable(“id”)整数id){
ModelAndView mav=新的ModelAndView(“类别表”);
List catFeatGroupList=catFeatGroupService.findGroupsForCategory(id);
mav.addObject(“catFeatGroupList”,catFeatGroupList);
返回mav;
}
这是我的表格
<form class="form-horizontal">
<div th:each="catFeatGroup,status : ${catFeatGroupList}" class="form-group">
<label>Position</label><input th:field="catFeatGroupList[${status.index}].position" th:value="${catFeatGroup.position}" />
<label>Name</label> <input name="catGroupList[${status.index}].name" th:value="${catFeatGroup.name}" />
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
位置
名称
提交
我需要使用th:field
绑定该对象,但出现以下错误:
无法分析为表达式:“catFeatGroupList[${status.index}].position”
像这样添加“_u”符号
<form class="form-horizontal">
<div th:each="catFeatGroup,status : ${catFeatGroupList}" class="form-group">
<label>Position</label><input th:field="*{catFeatGroupList[__${status.index}__].position}" th:value="${catFeatGroup.position}" />
<label>Name</label> <input data-th-name="*{catFeatGroupList[__${status.index}__].name}" th:value="${catFeatGroup.name}" />
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
位置
名称
提交
非常感谢。
