Spring 尝试从jsp向控制器发送数据时出现错误404

我有一个简单的J2ee应用程序。现在我想从jsp页面发送表单的数据

但是当我试着点击按钮时，我得到了错误代码404。我认为容器找不到资源

这是我的jsp代码：

<script language="javascript">  

            function saveRigaTable2(){

                try{
                    var ajaxHandler = new AjaxHandler('POST', '<c:out value="${pageName}"/>.htm', false);             
                    ajaxHandler.encodeParameter('method', '/saveItems');
                    ajaxHandler.encodeParameter('idRiga', 0);
                    ajaxHandler.callbackHandler = function()
                    {           
                        if (ajaxHandler.getRequest().readyState == 4)
                        {   
                            alert("pipo2 "+ajaxHandler.getRequest().status);                    
                            if (ajaxHandler.getRequest().status == 200)
                            {

                                var xmlDoc = ajaxHandler.getRequest().responseXML;
                                var items = xmlDoc.getElementsByTagName("exception");

                                if (items.length!=0)
                                {
                                    var punto=items[0];
                                    document.getElementById("error").innerHTML=punto.getAttribute("text");
                                    alert('Impossibile1 eseguire l\' operazione');
                                }
                                else
                                {
                                    reload();                           
                                }
                            }
                        }
                    };

                    ajaxHandler.startRequest();   
                }
                catch (e)
                {
                    alert('Impossibile eseguire l\' operazione');
                }      
            }
     </script>

<input type="button" value="Inserisci" onclick="javascript:saveRigaTable2();"/>

这是springmvcapp-servlet.xml的配置

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

        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

这是web.xml

错误在哪里？

${pageName}

的值是多少

你能试着用

代替

吗

var ajaxHandler=新的ajaxHandler（'POST'，'

此外，您还定义了一个控制器级别的

RequestMapping

，并且在每个方法上都会有一个重复的URI。

pageName的值为registering。我更改了代码，我使用insert.htm而不是.html。现在我没有404错误，但是如果我尝试在方法saveItems中插入断点，它还不会被调用。
