- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
在尝试实现 spring-security 时,我不断收到上述错误。请帮忙,因为我对 spring mvc 还很陌生
我尝试过使用提供的解决方案
No qualifying bean of type available in SpringBoot Application
No qualifying bean of type 'concert.PerformanceImp' available
还有其他一些,但我不明白为什么问题仍然存在
我的代码

@Autowired
private UserDetailsService userDetailsService;
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService);
}
.....
.....

}
MyUserDetailsService
@Component
public class MyUserDetailsService implements UserDetailsService {
@Autowired
private AccountDao accountDao;
@Transactional(readOnly=true)
@Override
public UserDetails loadUserByUsername(String email) throws UsernameNotFoundException {
Account account = accountDao.findAccountByEmail(email);
System.out.println("User " + account );
if(account == null ) {
throw new UsernameNotFoundException(
"User " + email + " was not found in database");
}
return (UserDetails) account;
}
