Spring security. Custom AuthenticationManager

提问by Igor Masternoy

I have spring mvc application. And i've added Spring Security with CustomAuthenticationManager. This is application-security.xml that included in appContex.xml. In login.jsp i use standart login page with 2 inputs: name='j_username' & name='j_password' and than in method in CustomAuthenticationManager.authenticate(Authentication authentication) i receive only password, but not principal with it name. What am i do wrong?

我有 spring mvc 应用程序。我已经使用 CustomAuthenticationManager 添加了 Spring Security。这是包含在 appContex.xml 中的 application-security.xml。在 login.jsp 中，我使用带有 2 个输入的标准登录页面：name='j_username' & name='j_password' 而在 CustomAuthenticationManager.authenticate(Authentication authentication) 中的方法中，我只收到密码，但不收到带有它的名称的主体。我做错了什么？

I recommend to use Security Namespace (link to the example of minimal configuration):
http://static.springsource.org/spring-security/site/docs/3.1.x/reference/springsecurity-single.html#ns-minimal

我建议使用安全命名空间（链接到最小配置示例）：http:
//static.springsource.org/spring-security/site/docs/3.1.x/reference/springsecurity-single.html#ns-minimal

Here the link how you can define your own authentication provider : http://static.springsource.org/spring-security/site/docs/3.1.x/reference/springsecurity-single.html#ns-auth-manager

这里是如何定义自己的身份验证提供程序的链接：http: //static.springsource.org/spring-security/site/docs/3.1.x/reference/springsecurity-single.html#ns-auth-manager

Creation of your own authentication provider solves most use cases. Please tell me if you need any additional clarifications.

创建您自己的身份验证提供程序可以解决大多数用例。如果您需要任何其他说明，请告诉我。

Best regards,

最好的祝福，
