Question

您好我得到了这个错误尝试学习一些Spring Java framrework。我有一个405 - 请求方法'POST'不支持我需要一些帮助，看看我的错误是什么

我的控制器

@Controller
@RequestMapping("overcomandant/addSitio.asp")
public class addSitioController {

    @RequestMapping(method = RequestMethod.GET)
    public ModelAndView addSitioForm() {

         ModelAndView asf = new ModelAndView();
         asf.setViewName("admin/addNewSite");
         asf.addObject("sitio", new Sitio());

         return asf;
    }

    @RequestMapping(value="admin/addNewSite", method = RequestMethod.POST)
    public String addSitioSubmit(Sitio st, ModelMap model) {

        model.addAttribute("url", st.getUrl());
        model.addAttribute("nombre", st.getNombre());
        model.addAttribute("estado", st.getEstado());

        return "admin/exito";

     }

     @ModelAttribute("estadoLista")
     public Map<String,String> ListadoEstados() {

         Map<String, String> estado = new LinkedHashMap<>();
         estado.put("1","Activo");
         estado.put("2","Inactivo");
         estado.put("3","Testing");

         return estado;

    }

 }

这是我的表单addNewSite.jsp

<form:form method="POST" commandName="sitio">

                <div class="form-group">
                <form:label path="id">ID</form:label>
                <form:input path="id" cssClass="form-control"/>
                </div>

                <div class="form-group">
                <form:label path="url">URL</form:label>
                <form:input path="url" cssClass="form-control"/>
                </div>

                <div class="form-group">
                <form:label path="nombre">Nombre</form:label>
                <form:input path="nombre" cssClass="form-control"/>
                </div>

                <div class="form-group">
                <form:label path="estado">Estado</form:label>
                <form:select path="estado" cssClass="form-control">
                    <form:option value="0">Seleccione</form:option>
                    <form:options items="${estadoLista}" />
                </form:select>
                </div>

                    <input type="submit" value="Enviar" class="btn btn-primary" /> 

            </form:form>

和exito.js

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 
        <title>JSP Page</title>
    </head>
    <body>
        <h1>Hello World!</h1>

        <p><c:out value="${url}"></c:out></p>

    </body> 
 </html>

我试着了解什么是狼。控制器创建一个对象站点，从表单中添加信息，然后otrer .jsp呈现新对象...

Answer 1

您必须指定表单操作以对应控制器中的方法：admin / addNewSite。

405错误告诉您表单操作未知。
