Question

当我提交下面提到的jsp表单时，它不会被提交，也不会在控制台中显示任何内容。浏览器显示HTTP 404状态并显示错误：客户端发送的请求在语法上不正确。

我的JSP页面是：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" 
pageEncoding="ISO-8859-1"%>
<%@ page isELIgnored="false" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Add task</title>
<link href="<c:url value='/static/css/bootstrap.css' />" rel="stylesheet">
</link>
<link href="<c:url value='/static/css/app.css' />" rel="stylesheet"></link>
<c:set var="root" value="${pageContext.request.contextPath}"/>
</head>

<body> 
<div class="generic-container">

    <div class="well lead">Add task</div>
    <form class="form-horizontal" action='<c:url value="addTask"/>'>
        <input type="hidden" name="id" id="id"/>

        <div class="row">
            <div class="form-group col-md-12">
                <label class="col-md-3 control-lable" 
for="taskDescription">Task name</label>
                <div class="col-md-7">
                    <input type="text" name="task" id="task" class="form-
control input-sm"/>
                    <div class="has-error">
                    </div>
                </div>
            </div>
        </div>

        <div class="row">
            <div class="form-group col-md-12">
                <label class="col-md-3 control-lable"

                <div class="col-md-7">

                </div>
            </div>
        </div>


        <div class="row">
            <div class="form-group col-md-12">
                <label class="col-md-3 control-lable" for="fromTime">From 
Time</label>
                <div class="col-md-7">
                    <input type="text" name="fromTime" id="fromTime"

                    <div class="has-error">
                    </div>
                </div>
            </div>
        </div>

        <div class="row">
            <div class="form-group col-md-12">
                <label class="col-md-3 control-lable" for="toTime">To 
Time</label>
                <div class="col-md-7">

                    <div class="has-error">
                    </div>
                </div>
            </div>

        <div class="row">
            <div class="form-actions floatRight">
                        <input type="submit" value="Add" class="btn btn-
primary btn-sm"/> 
            </div>
        </div>
    </form>

</body>
</html>

处理请求的控制器操作是AddTaskController中的/ addTask

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.websystique.springmvc.model.AddTask;
import com.websystique.springmvc.service.TaskService;

@Controller
@RequestMapping("/")
public class AddTaskController {

private TaskService taskService;

@RequestMapping("/task")
String task(){
    System.out.println("Inside task action");
    return "addTask/addTask";
}

@RequestMapping("/addTask")
String addTask(@ModelAttribute AddTask a){
    System.out.println("Inside addTask action");
    this.taskService.addTask(a);
    return "redirect:/task" ;
}

}

当我提交添加任务表单时，它显示错误：客户端发送的请求在语法上是不正确的

尝试以下更改

<body> 
<div class="generic-container">

    <c:url var="addTask" value="/addTask"/>

    <div class="well lead">Add task</div>
    <form class="form-horizontal" action="${addTask}">

请求语法不正确：spring mvc
