我可以使用休眠在单个 jsp 中有超过 1 个表单操作（表单内表单）吗

Question

在此jsp中，我使用了2个表单操作，一个用于保存角色（table：定义角色），另一个用于从其他table调用下拉列表（table：解决方案列表）。

点击提交后，没有任何反应。

如果我删除此表单(solutionMaster.html)

我收到此错误“无效的属性 'sMName' of bean class [com.mode;.definingrole]: Bean 属性 'sMName'不可读或具有无效的 getter 方法：getter 的 return 类型是否与 setter 的参数类型匹配？

是的，我知道原因，因为列 'sMName' 不是定义角色 table 的部分。怎么办。

我想知道的是，

我们可以在表单中创建表单吗？

2.Without 创建另一个表单，如何获取其他 table 的列值来定义角色 table?

请帮忙。

提前致谢。！！！

Answer 1

您正试图在 form 的标签下填充表单内部列表。这是错误的做法。您的 form 不会从 /solutionlist.html 获得值。如果你想使用 /solutionlist.html 控制器，你必须至少调用一个 GET。

如果我认为是，那么您必须执行以下操作

您不需要“/solutionlist.html”控制器。
只需将 ArrayList solutionList 绑定到提供表单页面的控制器方法中的模型中。我的意思是提供给定表单的 Controller 的 GET 方法。

ArrayList<String> solutionList=TemplateService.getSolutionListForTemplate(); model.put("solutionList", solutionList);
您将把 solutionList 作为值直接添加到您的表单中。因此，请按如下方式修改表单的 select 部分

<select name="solutions"path="Solutions"> <c:forEach items="${solutionList}" var="solution"> <option value="${solution}">${solution}</option> </c:forEach> </select>

我可以使用休眠在单个 jsp 中有超过 1 个表单操作（表单内表单）吗

Can I have more than 1 form action(form inside form) in single jsp using hibernate

forms

spring

jsp

action
