我可以从spring Controller设置一个隐藏的输入字段值(在jsp中)吗?

您可以从数据库中获取一些值(id)(使用findAllIdForUsers()方法)并使用模型转发到您的JSP:
@Autowired
ServiceInterface service;
@RequestMapping(value = "example.html", method = RequestMethod.GET)
public String viewUsers(Model model){
model.addAttribute("usersId", service.findAllIdForUsers());
return "example";
}
在JSP上,您可以在某个按钮上设置此ID:
<c:forEach items="${ requestScope['users'] }" var="users">
<form action="<%=response.encodeURL(request.getContextPath() + "delete.html") %>" method="POST">
<input type="hidden" name="id" value="<c:out value="${ usersId.id }"/>" />
<input type="SUBMIT" value="Delete User" /></form>
</c:forEach>
然后在按钮上单击,您可以将id发送到另一个控制器并工作或删除该用户:
@RequestMapping(value = "delete.html", method = RequestMethod.POST)
public String deleteUser(@RequestParam("id") int id, Model model) {
service.delete(id);
model.addAttribute("usersId", service.findAllIdForUsers());
return "example";
}
