返回用户名和密码登录grails spring security [英] Return username and password to login form grails spring security

问题描述

当用户身份验证失败时，我希望将用户名和密码返回到表单。
我将Spring安全核心插件与Grails和Spring Security LDAP一起使用。我搜索了一段时间，并拿出了邮编。任何想法？

When a user fails authentication, I want the username and password to be returned to the form. I'm using the spring security core plugin with Grails and Spring Security LDAP. I've searched around for a while and have come up with zip. Any ideas?

推荐答案

从 UsernamePasswordAuthenticationFilter javadoc：

如果您想保留用户名，请将其缓存在自定义的AuthenticationFailureHandler中

If you want to retain the username, cache it in a customized AuthenticationFailureHandler

至于密码，没有意义要缓存它，因为出于安全原因无法将它放回密码字段。

As for password there is no point to cache it, because it cannot be put back to form password field for security reasons.
