        List<GrantedAuthority> authorities = new ArrayList<>();
        authorities.add(new SimpleGrantedAuthority("ROLE_" + account.getRole()));
        User user = new User(account.getName(), passwordEncoder.encode(account.getPassword()), authorities);
        System.out.println(user.getUsername() + passwordEncoder.encode(account.getPassword()) + user.getAuthorities());
        return user;
    }
}

使用的mybatis数据库，数据库没问题

你的问题出现在这一步，这些都是多余的，光该这个的话，把这些删了就行。

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService()).passwordEncoder(new BCryptPasswordEncoder());
    }
