Question

我对某个问题感到有点困惑，我在更新用户对象时反复遇到405 Method Not Allowed的问题。但是，控制器代码和HTML表单似乎是正确的。如果我将RequestMethod.PUT更改为RequestMethod.POST它可以正常工作。我在这里错过了什么吗？

我使用以下网址方案

/user [GET] - user list
/user/new [GET] - form to create a new user
/user [POST] - create user
/user/{id}/edit [GET] - form to edit user
/user/{id} [PUT] - update the user
/user/{id} [DELETE] - delete the user

您必须在web.xml中使用HiddenHttpMethodFilter，请参阅下文。

<filter>
    <filter-name>hiddenmethodfilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>hiddenmethodfilter</filter-name>
    <servlet-name>dispatchers-name</servlet-name>
</filter-mapping>

在你的html / jsp中使用Spring tld表单标签，并在表单中包含 _method = PUT 。

PUT上不支持Spring MVC-405方法
