单独新建对象保存用户信息（并且实现UserDetails接口）

public class CustomUserDetails implements UserDetails {

    private User user;

    public CustomUserDetails(User user) {
        this.user = user;
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        // TODO: get authorities
        return AuthorityUtils.commaSeparatedStringToAuthorityList("");
    }

    @Override
    public String getPassword() {
        return user.getPassword();
    }

    @Override
    public String getUsername() {
        return user.getUsername();
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return true;
    }
}

新建对象实现UserDetailsService接口，自定义加载用户方法，本案例只传入一个固定账号密码。[ 会配置多账号的系统，可以通过username查表获取用户信息，使用该用户的用户id、密码来new User() ]

@Service
public class CustomUserDetailsServiceImpl implements UserDetailsService {

    /**
     * 加载用户
     *
     * @param userName username用户名
     * @return CustomUserDetails
     * @throws UsernameNotFoundException 找不到用户异常
     */
    @Override
    public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException {
        if (userName.equals("root")) {
            User user = new User(userName, new BCryptPasswordEncoder().encode("123456"), new ArrayList<>());
            return new CustomUserDetails(user);
        }
        t
