【问题描述】：
假设我有这个控制器：
import org.java.wsg.service.ClientsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.support.PagedListHolder;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import javax.servlet.http.HttpServletRequest;
@Controller
public class ClientsController {
@Autowired
ClientsService clientsService;
@RequestMapping(value = "/clients.htm")
public String clientsPage(HttpServletRequest request, Model model) {
PagedListHolder pagedList = new PagedListHolder(clientsService.getClients());
pagedList.setPageSize(50);
request.getSession().setAttribute("clientsList", pagedList);
model.addAttribute("clients", pagedList.getPageList());
return "clients";
}
@RequestMapping(value = "/clientsNavigate.htm", method = RequestMethod.POST)
public String clientsNavigateToPage(HttpServletRequest request, Model model,
@RequestParam String action) {
PagedListHolder pagedList = (PagedListHolder) request.getSession().getAttribute("clientsList");
if (action.equals("next")) {
pagedList.nextPage();
} else if (action.equals("previous")) {
pagedList.previousPage();
}
model.addAttribute("clients", pagedList.getPageList());
return "clients";
}
@RequestMapping(value = "/clients/{id}.htm", method = RequestMethod.GET)
public String clientById(Model model, @PathVariable Integer id, HttpServletRequest request) {
PagedListHolder pagedList = new PagedListHolder(clientsService.getClientById(id));
pagedList.setPageSize(50);
request.getSession().setAttribute("clientsList", pagedList);
model.addAttribute("clients", pagedList.getPageList());
return "clients";
}
}
编辑：
这是一个clients.jsp 页面：
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

</c:forEach>

<form:form method="post" action="clientsNavigate.htm">

如您所见，第一个方法 (clientsPage) 获取 Client 对象的列表并将它们作为属性传递给 clients.jsp 页面。第二种方法（clientsNavigateToPage）用于处理clients.jsp页面中的表单请求（带有两个按钮（Next和Previous）的简单表单）。第三种方法用于获取具有某个id的多个客户端。但我面临的问题是在处理我的/clients/{id}.htm 请求后，我无法处理我的/clientsNavigate.htm 请求。
它说：
HTTP Status 405 - Request method 'POST' not supported
如何处理这个问题？
【问题讨论】：
-
请包含您的 HTML（或用于发送表单的任何内容）代码。
-
您是否检查过表单
action是否正确，即该请求是否发送到正确的控制器？尝试从映射中删除method = RequestMethod.POST。尽管这似乎是正确的，但让我们检查一下删除它是否有帮助。 -
@MichałRybak 刚刚检查过。是的，它已发送到正确的控制器。
-
删除
method = RequestMethod.POST有帮助吗？ -
@MichałRybak 不，它没有。
