如何使用spring創建自定義用戶會話對象

Question

我構建了一個簡單的webapp，它是我學習彈簧技術的一部分。

我正在考慮創建一些自定義用戶會話，該會話持有許多用戶屬性的引用，例如語言，貨幣等等。

我怎樣才能在春天實現這一目標？或者有一些已經存在的東西？

您可以編寫自定義authentication provider，並通過自定義UserDetailsService

<authentication-manager> 
    <authentication-provider user-service-ref="customUserService" /> 
</authentication-manager> 

<beans:bean id="customUserService" class="custom.UserServiceImpl"> 
</beans:bean> 

public class UserServiceImpl implements UserDetailsService { 

    @Override 
    public UserDetails loadUserByUsername(String username) 
      throws UsernameNotFoundException { 
     //Your logic 
     return new AuthenticatedUser("", "", true, true, true, new HashSet<GrantedAuthority>()); 
    } 
} 

public class AuthenticatedUser extends 
     org.springframework.security.core.userdetails.User { 
    private static final long serialVersionUID = 1L; 

    // Your additional properties 

    public AuthenticatedUser(String username, String password, 
      boolean enabled, boolean accountNonExpired, 
      boolean credentialsNonExpired, 
      Collection<? extends GrantedAuthority> authorities) 
      throws IllegalArgumentException { 
     super(username, password, enabled, accountNonExpired, 
       credentialsNonExpired, true, authorities); 
    } 
}
