HTTP状态405-请求方法'POST'不支持

HTTP Status 405 - Request method 'POST' not supported

` 我在ftl和controller上都给出了POST方法.那为什么会这样呢?

` I gave POST method on both ftl and controller. Then why would this happen?

推荐答案

我不确定是否有帮助，但是我遇到了同样的问题.

I am not sure if this helps but I had the same problem.

您正在使用具有CSRF保护的springSecurityFilterChain.这意味着通过POST请求发送表单时必须发送令牌.尝试将下一个输入添加到您的表单中:

You are using springSecurityFilterChain with CSRF protection. That means you have to send a token when you send a form via POST request. Try to add the next input to your form:

<input type="hidden"
name="${_csrf.parameterName}"
value="${_csrf.token}"/>
