我创建了一个新的SpringMVC项目，然后在index.jsp中向名为springController.java的Spring控制器发送帖子。文件index.jsp:

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
    "http://www.w3.org/TR/html4/loose.dtd">

        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

        <script type="text/javascript" src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script>
        <title>Welcome to Spring Web MVC project</title>

        <script type="text/javascript">
             $(document).ready(function(){
                 $("#testForm").submit(onFormSubmit);
             });
             function onFormSubmit(e){

                 data = $("#testForm").serialize();
                // console.log(data);
                 $.post("/test/another");
                 e.preventDefault();
             }

        </script>
    </head>

    <body>
        <form id="testForm">
            <label>Imie: </label>
            <input type="text" name="login">
            <label>Nazwisko: </label>
            <input type="text" name="password">
            <input id="testPostButton" type="submit">
        </form>

    </body>
</html>

但是sendindpost不起作用，在WebInspector的控制台中我得到

 POST http://localhost:8084/test/another 404 (Not Found)

现在我只想从index.jsp发送catch POST。不幸的是，我是春季MVC的新手，我不知道我做错了什么。以下是dispatcher-servlet.xml：

<?xml version="1.0" encoding="UTF-8"?>

for the index controller we are using ParameterizableViewController, so we must

索引控制器

下面是web.xml：

    <welcome-file-list>

我不知道出了什么问题，为什么我不能从springController.java中的index.jsp捕获“POST”。这是我在StackOverflow上的第一篇文章，如果有人决定帮助我，我会非常高兴

来自波兰的问候，感谢您的帮助

这是文件应用程序上下文，我必须将文件粘贴到这里，因为我是新来的，没有足够的声誉。仍然在WebInspector的控制台中，我收到了与前面相同的消息：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"

    http://www.springframework.org/schema/mvc 
    http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">




<context:component-scan base-package="by" use-default-filters="false">
    <context:include-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
</context:component-scan>

<mvc:annotation-driven />
</beans>

尝试取消注释

RequestMethod.POST

在方法定义之上

还要确保您的控制器被spring识别为bean。您用@controller注释了类。要使其工作，您可以向applicationContext.xml添加配置：

    <context:component-scan base-package="newpackage" use-default-filters="false">
        <context:include-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
    </context:component-scan>

    <mvc:annotation-driven />

不幸的是，它仍然不起作用，可能我将您的代码粘贴到了错误的位置，我必须在第一篇文章中粘贴文件applicationContext，因为回复消息太长，而且我没有足够的声誉来回答我自己。抱歉，请尝试将的“base package”属性从“by”更改为“newpackage”（您的类所在的包）。

    <context:component-scan base-package="newpackage" use-default-filters="false">
        <context:include-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
    </context:component-scan>

    <mvc:annotation-driven />
