auth.userDetailsService(userDetailsService).passwordEncoder()意思

这段代码是为了配置Spring Security中的密码编码器和用户详细信息服务。
userDetailsService参数是一个实现了UserDetailsService接口的类,用于提供用户详细信息。
passwordEncoder()是用来配置密码编码器的方法,它返回一个PasswordEncoder对象。这个对象用于对用户密码进行加密和解密。如果不配置密码编码器,Spring Security会使用默认的NoOpPasswordEncoder,这是一种不安全的编码器,不建议使用。
通常,我们会使用比较安全的BCryptPasswordEncoder来对密码进行加密。因此,我们可以将passwordEncoder()方法改为:
.passwordEncoder(new BCryptPasswordEncoder())
这样就会使用BCryptPasswordEncoder来对密码进行加密。

auth.userDetailsService(userDetailsService).passwordEncoder()
This is a method call in Spring Security configuration that sets the userDetailsService and passwordEncoder properties for authentication.
The userDetailsService is an interface that loads user-specific data, such as the user's username, password, and roles, from a persistent data store. The passwordEncoder is an interface that encrypts and compares passwords.
By setting these properties, Spring Security knows how to authenticate users and check their passwords.
For example:
```
@Autowired
private UserDetailsService userDetailsService;
@Bean
public DaoAuthenticationProvider authenticationProvider() {
DaoAuthenticationProvider authProvider = new DaoAuthenticationProvider();
authProvider.setUserDetailsService(userDetailsService);
authProvider.setPasswordEncoder(new BCryptPasswordEncoder());
return authProvider;
}
```
In this code snippet, the userDetailsService is injected using the @Autowired annotation, and a new instance of DaoAuthenticationProvider is created with the userDetailsService and a new BCryptPasswordEncoder. This allows Spring Security to authenticate users using the provided user details and encrypted passwords.
auth.userdetailsservice
auth.userdetailsservice是Spring Security框架中的一个接口,用于获取用户的详细信息。它定义了一个方法loadUserByUsername,该方法根据用户名加载用户的详细信息,例如密码、角色、权限等。开发人员可以实现这个接口,自定义用户信息的获取方式,以满足不同的业务需求。
