我可以使用休眠在单个 jsp 中具有 1 个以上的表单操作(表单内的表单)吗?

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(表：解决方案列表)调用下拉列表。

单击提交后，它没有执行任何操作。

如果我删除此表单(解决方案大师.html)

我收到此错误" bean 类 [com.mode; 的无效属性'sMName'。definingrole]：Bean 属性 'sMName' 不可读或具有无效的 getter 方法：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"sMName"列不是定义角色表的一部分。这怎么办。

我想知道的是，

我们可以在表单中创建表单吗？

2.在不创建其他表单的情况下，如何获取其他表的列值以定义角色表？

请帮忙。

提前谢谢.!!

model.put("listOfTemplate",listOfTemplate);
return TEMPLATESUMMARY;
}

控制器：解决方案名称.html

@RequestMapping("/solutionlist.html")
public String solutionName(Map<String, Object> model,solutionlist sol) throws Exception {
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
String name = auth.getName();
String nameOfUser=TemplateService.getEmpNameOfUser(name);
model.put("nameOfUser",nameOfUser);
solutionlist soltemp = new solutionlist();
model.put("soltemp", soltemp);
ArrayList<String> solutionList=TemplateService.getSolutionListForTemplate();
model.put("solutionList", solutionList);
return REDIRECT_TEMPLATESUMMARY_URL;
}

您正在尝试在form标签下填充表单中的列表。这是错误的方法。您将无法从/solutionlist.html中获得价值form.如果要使用控制器/solutionlist.html则必须至少调用GET。

如果我认为是这样，那么你必须执行以下操作

您不需要"/解决方案列表.html"控制器。
只需将 ArrayListsolutionList绑定到表单页所在的控制器方法中的模型中即可。我的意思是提供给定表单的控制器的GET方法。

ArrayList<String> solutionList=TemplateService.getSolutionListForTemplate(); model.put("solutionList", solutionList);
您将把该solutionList作为值直接作为值发送到您的表单中。因此，修改表单的select部分，如下所示

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