我正在通过阅读学习Spring4。现在，我遇到了一个关于Spring Security的问题。当我请求“/ home”时，我得到了登录页面，但是当我填写表单并提交时，我无法进入UserDetailsService 但直接转到控制器然后返回登录页面。我调试它，发现 spitterUserDetailsService 不为空，它是自动装配的。所以我不知道是什么问题。这是我的代码。提前致谢。
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserDetailsService spitterUserDetailsService;
@Override
protected void configure(HttpSecurity http) throws Exception{
http.formLogin().loginPage("/spitter/login").permitAll()
.and().rememberMe()
.and().authorizeRequests().antMatchers("/spitter/home").hasRole("SPITTER")
.anyRequest().permitAll();
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception{
auth.userDetailsService(spitterUserDetailsService);
}
}
@Service
public class SpitterUserDetailsService implements UserDetailsService {
@Autowired
private SpitterRepository spitterRepository;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
System.err.println("---------- User Details Service start -----------");
Spitter spitter = spitterRepository.findByUsername(username);
if(spitter == null){
throw new UsernameNotFoundException(username + " not found ");
}
List<SimpleGrantedAuthority> authorities = new ArrayList<SimpleGrantedAuthority>();
authorities.add(new SimpleGrantedAuthority("ROLE_SPITTER"));
System.out.println(spitter.getUsername() + " : ROLE_SPITTER");
return new User(spitter.getUsername(), spitter.getPassword(), authorities);
}
}
@Controller
@RequestMapping("/spitter")
public class SpitterController {
@Autowired
private SpitterRepository spitterRepository;
@RequestMapping(value= "/login", method = RequestMethod.GET)
public String login(Model model){
model.addAttribute("spitter", new Spitter());
return "spitter/login";

System.out.println(spitter.getUsername() + " logined..");
