Java Config Spring Security FORM_LOGIN_FILTER
提问by crownedzero
I'm working through some of the Spring Security tutorials and trying to implement them without xml and I can't seem to find a anything about replacing the default UsernamePasswordAuthenticationFilter.
我正在阅读一些 Spring Security 教程并尝试在没有 xml 的情况下实现它们，但我似乎找不到任何关于替换默认UsernamePasswordAuthenticationFilter 的内容。
Similar to this questionI'd like to retrieve an extra parameter from the login form. Where I'm having difficulty is:
与这个问题类似，我想从登录表单中检索一个额外的参数。我遇到困难的地方是：
<custom-filter ref="customAuthenticationProcessingFilter" position="FORM_LOGIN_FILTER"/>
In order to set this up properly do I need to build from the AuthenticationManagerBuilder down? or am I missing something?
为了正确设置它，我是否需要从 AuthenticationManagerBuilder 向下构建？或者我错过了什么？

According to the Spring Security documentation found here:
根据此处找到的 Spring Security 文档：
http://docs.spring.io/spring-security/site/docs/3.0.x/reference/ns-config.html#filter-stack
http://docs.spring.io/spring-security/site/docs/3.0.x/reference/ns-config.html#filter-stack
FORM_LOGIN_FILTER is just an alias for the class UsernamePasswordAuthenticationFilter.
FORM_LOGIN_FILTER 只是 UsernamePasswordAuthenticationFilter 类的别名。
So
所以
http.addFilterBefore(new YourFilter(), UsernamePasswordAuthenticationFilter.class);
Should do the trick
应该做的伎俩

Thanks @Juan for good doc link. But you must use addFilterAtinstead of addFilterBefore.
感谢@Juan 提供良好的文档链接。但是您必须使用addFilterAt代替addFilterBefore.
So, this is correct :
所以，这是正确的：
http.addFilterAt(new YourFilter(),UsernamePasswordAuthenticationFilter.class);
This will replace the existing default implementation with your CustomFilter.
这将用您的 CustomFilter 替换现有的默认实现。
