SpringSecurity/Grails如何在运行时动态更改LoginUrlAuthenticationEntryPoint中的loginFormUrl? [英] SpringSecurity/Grails how to change loginFormUrl in LoginUrlAuthenticationEntryPoint dynamically at runtime?

问题描述

我需要在运行时动态地将后缀附加到配置值"grails.plugin.springsecurity.auth.loginFormUrl =/login/auth".因此，我认为我必须在类"LoginUrlAuthenticationEntryPoint"中更改字段"loginFormUrl".不赞成使用方法"setLoginFormUrl"，所以我想知道如何在运行时更改它?我是否应该每次都需要注入/创建一个新的"LoginUrlAuthenticationEntryPoint"?我将如何/在何处这样做?

I need to append a suffix to the config value "grails.plugin.springsecurity.auth.loginFormUrl = /login/auth" dynamically at runtime. So I think I would have to change the field "loginFormUrl" in class "LoginUrlAuthenticationEntryPoint". The method "setLoginFormUrl" is deprecated so I wonder how can I change that at runtime? Should I inject/create a new "LoginUrlAuthenticationEntryPoint" everytime I need to do that? How/where would I do that?

推荐答案

因此，解决方案非常简单.我实现了自己的AuthenticationEntryPoint，它与LoginUrlAuthenticationEntryPoint非常相似，但是对defineUrlToUseForThisRequest方法具有不同的实现.

So the solution is quite simple. I implemented my own AuthenticationEntryPoint which is pretty much like the LoginUrlAuthenticationEntryPoint but has a different implementation of the determineUrlToUseForThisRequest method.

然后，您只需将其添加到您的资源.groovy:

Then you only have to add this to your resources.groovy:

authenticationEntryPoint(MyCustomEntryPoint) {}
