security中loadUserByUsername传入多个参数

在Spring Security中，loadUserByUsername方法只接受一个参数，即用户名。该方法用于加载用户的详细信息，例如密码、角色、权限等。如果需要传入多个参数，则可以通过自定义UserDetailsService来实现。可以创建一个包含多个参数的自定义UserDetails类，然后在UserDetailsService的实现类中使用该类来加载用户详细信息。例如：

public class CustomUserDetails implements UserDetails {

    private String username;
    private String password;
    private List<GrantedAuthority> authorities;

    public CustomUserDetails(String username, String password, List<GrantedAuthority> authorities) {
        this.username = username;
        this.password = password;
        this.authorities = authorities;
    }

    // 省略其他实现方法
}

@Service
public class CustomUserDetailsService implements UserDetailsService {

    @Autowired
    private UserRepository userRepository;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = userRepository.findByUsername(username);
        if (user == null) {
            throw new UsernameNotFoundException("User not found");
        }

        List<GrantedAuthority> authorities = new ArrayList<>();
        authorities.add(new SimpleGrantedAuthority(user.getRole()));

        return new CustomUserDetails(user.getUsername(), user.getPassword(), authorities);
    }
}

在上面的例子中，CustomUserDetails类包含了用户名、密码和权限三个参数。CustomUserDetailsService类使用userRepository来加载用户信息，并将用户的角色转换为GrantedAuthority对象。最后，loadUserByUsername方法返回一个CustomUserDetails对象，该对象包含了所有用户信息。
