Question

在这个jsp中，我使用了2个表单操作，一个用于保存角色（表：定义角色），另一个用于从其他表调用删除列表（table：solutionList）。

点击提交后，它没有做任何事情。

如果我删除此表单（solutionMaster.html）

我收到此错误＆＃34;无效的属性＆＃39; sMName＆＃39; bean类[com.mode; .definingrole]：Bean属性＆＃39; sMName＆＃39;不可读或getter方法无效：getter的返回类型是否与setter的参数类型匹配？。

是的，我知道原因，因为专栏＆＃39; sMName＆＃39;不是定义角色表的一部分。怎么做。

我想知道的是，

我们可以在表单内创建表单吗？

2.如果没有创建另一个表单，我怎样才能将其他表的列值定义为定义角色表？

请帮忙。

提前致谢。!!!

Answer 1

您正尝试在/solutionlist.html标记下填写表单内的列表。哪种方法不对。您无法通过form从GET获得价值。如果您想使用/solutionlist.html控制器，则必须至少拨打solutionList。

如果我认为那么你必须做以下

您不需要＆＃39; /solutionlist.html'控制器。
只需将ArrayList GET绑定到表单页面所服务的控制器方法中的模型中。我的意思是控制器的ArrayList<String> solutionList=TemplateService.getSolutionListForTemplate(); model.put("solutionList", solutionList);方法，其中提供给定的表单。

solutionList
您将select直接作为值获得表单。因此，修改表单的<select name="solutions"path="Solutions"> <c:forEach items="${solutionList}" var="solution"> <option value="${solution}">${solution}</option> </c:forEach> </select>部分如下

我可以使用hibernate在单个jsp中拥有多个表单动作（表单内部形式）
