UserDetailsService

DaoAuthenticationProvider使用 {security-api-url}org/springframework/security/core/userdetails/UserDetailsService.html[UserDetailsService] 来检索用户名、密码和用于通过用户名和密码进行身份验证的其他属性。Spring Security 提供 `UserDetailsService`的 in-memory、JDBC和 caching实现。

{security-api-url}org/springframework/security/core/userdetails/UserDetailsService.html[UserDetailsService] is used by DaoAuthenticationProvider for retrieving a username, a password, and other attributes for authenticating with a username and password. Spring Security provides in-memory, JDBC, and caching implementations of UserDetailsService.

您可以通过将自定义 UserDetailsService 作为 bean 呈现来定义自定义验证。例如，以下清单自定义了验证，假定 CustomUserDetailsService 实现了 UserDetailsService：

You can define custom authentication by exposing a custom UserDetailsService as a bean. For example, the following listing customizes authentication, assuming that CustomUserDetailsService implements UserDetailsService:

仅当 AuthenticationManagerBuilder 未填充且未定义 AuthenticationProviderBean 时，此才可用。

This is only used if the AuthenticationManagerBuilder has not been populated and no AuthenticationProviderBean is defined.
