不支持请求方法'POST'Spring

我正在编写一个控制器来处理来自AJAX的帖子。我不断收到该帖子不支持的错误。在尝试创建后控制器方法之前，我从来没有得到下面的错误，我希望有人能够发现我搞砸了。不支持请求方法'POST'Spring

这是我写来控制控制器后的方法：

@RequestMapping(value = "/clearVendorBillingPO", method = RequestMethod.POST) 
public @ResponseBody String setClearVendorBillingPO(HttpServletRequest request, @RequestParam("Id") BigInteger Id) 
       throws Exception { 
    System.out.println("sucess!!"); 
    return "str"; 
}

使用jQuery 1.10 这是AJAX调用正在请求是：

$.ajax({ 
    url : '/UI/clearVendorBillingPO', 
    dataType: 'json', 
    type : 'POST', 
    data : { "Id": Id, "_csrf":csrf }, 
    async : true, 
    success : function(data) { 
     console.log("successful!") 
    }, 
    fail: function(e) { 
     jqAlert("There was a problem clearing the PO"); 
    } 
});

我知道POST地址是正确的，因为将其转换为GET请求可以很好地工作。还有其他的POST请求我已经写在同一个控制器类中正常工作。任何有关可能导致此问题的见解，我们感激不尽！

你用@RequestMapping注释了你的控制器？（对于UI部分。）也是为控制器创建的bean？它是否被自动检测机制发现？ Spring在启动时会记录所有映射的URL（至少在Spring启动时）。 –

您在ajax调用中发生错误。方法是：“POST”不是类型。

$.ajax({ 
    url : '/UI/clearVendorBillingPO', 
    dataType: 'json', 
    method : 'POST', 
    ...

我很欣赏这种努力。但这不是问题。从Jquery网站：类型（默认值：'GET'）类型：字符串方法的别名。如果您使用1.9.0之前版本的jQuery，则应该使用类型。 – user2725919

@ user2725919在你的问题中你说你使用的是1.10版本的JQuery，你能不能粘贴你正在做的请求调用？与一些网络流量检查员，你可以得到它。（Firebug，铬） – cralfaro
