spring security 4.0.1 - HTTP 状态 405 - 不支持请求方法“POST”

Question

我正在使用 Spring MVC (4.1.6 RELEASE) 和 Spring Security (4.0.1 RELEASE)。

当我尝试提交登录表单时，我收到“HTTP 状态 405 - 不支持请求方法‘POST’。”错误。

Answer 1

登录提交操作的默认登录端点是 /login。您在 login.html 中有端点 j_spring_security_check，spring 不知道它如何处理此映射。因此，也可以尝试使用带有 ids/names 用户名/密码的输入元素：

<form  action="/login" name="f" method="post" >
    <input id="username" name="username" type="text" />
    <input id="password" name="password" type="password"/>
    <input name="submit" id="button" type="submit" value="enter" />
</form>

请修改 中的两个条目（servlet-config.xml、spring-security.xml）。 将 url-mapping 更改为：

<servlet-mapping>
    <servlet-name>ISMServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

Answer 2

我认为在sprng-security 4中默认启用了csrf保护。所以在你的登录表单中添加这一行

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