Spring安全服务配置

Question

我正在尝试使用不同的框架构建Java应用程序原型。除了安全层，一切都很好。我选择使用Spring配置配置的Security。

代码如下：

Security

@Configuration
@EnableWebMvcSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter
{
    @Autowired
    private MyUserDetailsService userDetailsService;

    @Override
    protected UserDetailsService userDetailsService () {
        return this.userDetailsService;
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web
        .ignoring()
        .antMatchers("/resources/**");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
        .formLogin()
        .loginPage("/login")
        .loginProcessingUrl("/login/authenticate")
        .failureUrl("/login?error=bad_credentials")
        .and()
        .logout()
        .logoutUrl("/signout")
        .deleteCookies("JSESSIONID")
        .and()
        .authorizeRequests()
        .antMatchers("/admin/**").hasRole("ADMIN")
        .antMatchers("/**").permitAll()
        .and()
        .csrf();
    }
}

用户详细服务

@Service("myUserDetailsService")
public class MyUserDetailsService implements UserDetailsService
{
    public static final Logger log = Logger.getLogger(MyUserDetailsService.class);

    public MyUserDetailsService() {
    }

    @Autowired
    private UserDao userDao;

    @Override
    public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException {
        final User user = getSystemUser(userName);
        final List<GrantedAuthority> authorities = getUserAuthorities(user);
        return buildUserForAuthentication(user, authorities);
    }

    private User buildUserForAuthentication(User user, List<GrantedAuthority> authorities) {
        //...
    }

    private User getSystemUser(String alias) {
        //...
    }

    private List<GrantedAuthority> getUserAuthorities(User user) {
        //...
        return null;
    }
}

我期待这段代码所做的是，当用户& pass参数到达/login/authenticate时，底层的spring代码会调用我的用户服务，但这种情况从未发生过。

我遗漏了什么？

我用的是弹簧安全3.2.3。

您应该在扩展了SecurityConfig的WebSecurityConfigureAdapter类中注册您的自定义身份验证：

@Autowired
private MyUserDetailsService userDetailsService;

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

对于3.2.3，配置应该是

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