我猜这与该配置类的自动装配属性有关：
@Configuration
@ComponentScan(value="spring.example")
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UsuarioService usuario;
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth
.userDetailsService(usuario)
.passwordEncoder(encoder());
}
private Md5PasswordEncoder encoder() {
return new Md5PasswordEncoder();
}
protected void configure(HttpSecurity http) throws Exception {
http
.csrf()
.disable()
.authorizeRequests()
.antMatchers("/acesso/erro").permitAll()
.antMatchers("/resources/**").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/acesso/login").permitAll()
.loginProcessingUrl("/login").permitAll()
.usernameParameter("login")
.passwordParameter("senha")
.defaultSuccessUrl("/acesso/start")
.failureUrl("/acesso/login")
.and()
.rememberMe()
.key("lembrete")
.useSecureCookie(true)
.and()
.logout()
.logoutUrl("/logout")
.logoutSuccessUrl("/acesso/login").permitAll();
}
}
我的类UsuarioService.java具有以下实现：
@Service
public class UsuarioService implements UserDetailsService {
private UsuarioDao usuario;
@Transactional(readOnly = true, propagation = Propagation.SUPPORTS)
public UserDetails loadUserByUsername(String arg0) throws UsernameNotFoundException {
Usuario account = usuario.findByField("login", arg0);
if(account==null) {
throw new UsernameNotFoundException("No such user: " + arg0);
} else if (account.getAutorizacao().isEmpty()) {
throw new UsernameNotFoundException("User " + arg0 + " has no authorities");
}
boolean accountIsEnabled = true;
boolean accountNonExpired = true;
boolean credentialsNonExpired = true;
boolean accountNonLocked = true;
return new User(account.getLogin(), account.getSenha(), accountIsEnabled, accountNonExpired, credentialsNonExpired, accountNonLocked, getAuthorities(account.getAutorizacao()));
}
public List<String> getRolesAsList(List<Autorizacao> list) {
List <String> rolesAsList = new ArrayList<String>();
for(Autorizacao role : list){
rolesAsList.add(role.getNome());
}
return rolesAsList;
}
public static List<GrantedAuthority> getGrantedAuthorities(List<String> roles) {
List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
for (String role : roles) {
authorities.add(new SimpleGrantedAuthority(role));
}
return authorities;
}
public Collection<? extends GrantedAuthority> getAuthorities(List<Autorizacao> list) {
List<GrantedAuthority> authList = getGrantedAuthorities(getRolesAsList(list));
return authList;
}
}
有什么可以为我指出正确的方向？我在SecurityConfig类中提供了另一种使用此Service类的方法，但是我可以发现我的代码与Web上的其他代码有什么不同。
最佳答案
您将在SpringConfig中自动装配具体的类（UsuarioService），而不是接口（UserDetailsService）。看一下answer here 中的点2）。
您应该在配置中像这样自动连接UserDetailsService：
@Autowired
private UserDetailsService usuario;
