如果用户尝试使用错误的凭据进行身份验证，我想记录。因此，我已将此事件监听器类添加到我的项目中:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.ApplicationListener;
import org.springframework.security.authentication.event.AuthenticationFailureBadCredentialsEvent;
import org.springframework.stereotype.Component;

@Component
public class AuthenticationFailureListener
        implements ApplicationListener<AuthenticationFailureBadCredentialsEvent>{

    private final Logger logger = LoggerFactory.getLogger(getClass());

    @Override
    public void onApplicationEvent(AuthenticationFailureBadCredentialsEvent event) {
        System.out.println("test");
        logger.info("test2");
    }
}

问题是它根本不起作用。我使用 Spring Security 默认登录页面。使用错误的凭据时，页面会显示“错误的凭据”错误，但不会调用我上面的方法。 我有非常相似的成功事件监听器代码，效果非常好:

@Component
public class AuthenticationSuccessListener implements
        ApplicationListener<InteractiveAuthenticationSuccessEvent> {

    private final Logger logger = LoggerFactory.getLogger(getClass());

    @Autowired private UserService users;

    @Override
    public void onApplicationEvent(InteractiveAuthenticationSuccessEvent event) {
        User user = users.get(event.getAuthentication().getName());
        boolean isAdmin = user.getRole().equals(User.ROLE_ADMIN);
        logger.info((isAdmin ? "Admin" : "User") + " with id " + user.getIdLink()
                + " has successfully logged in!");
    }
}

这是我的 Spring Security Java 配置:

@Configuration
@EnableWebMvcSecurity
@EnableGlobalMethodSecurity(prePostEnabled=true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter{

    @Autowired
    private CustomUserDetailsService userDetailsService;

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

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

    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf().disable()
            .formLogin()
                .and()
            .httpBasic();
    }
}

我不知道这里发生了什么，非常感谢帮助!

Spring 版本:4.0.9
Spring Security 版本:3.2.5(也试过4.0.1)

编辑:

好的，我将 Spring 的日志级别设置为 DEBUG，但什么也没有。我搜索了“Listener”的每一次出现，日志指出 AuthenticationFailureListener 和 AuthenticationSuccessListeners 的实例已创建且没有任何错误。

我什至将日志放入差异工具(在替换所有时间和审查之后)并与 FailureListener 代码被注释掉的代码版本进行比较，但没有找到任何东西。有需要的可以自行搜索:

在页面底部，您会在左侧找到纯日志文本。

Edit2:部分解决

Serges 解决方案有帮助，这是我对 onAuthenticationFailure 方法的完整实现:​​

@Override
public void onAuthenticationFailure(
        HttpServletRequest request, HttpServletResponse response,
        AuthenticationException exception) throws IOException, ServletException {

    if (exception instanceof BadCredentialsException) {
        String name = request.getParameter("username");
        String password = request.getParameter("password");
        Authentication auth =
                new UsernamePasswordAuthenticationToken(name, password);
        eventPublisher.publishEvent(
                new AuthenticationFailureBadCredentialsEvent(auth, exception));
    }
    super.onAuthenticationFailure(request, response, exception);
}

最佳答案

我以不同的方式让它工作。

@Configuration
@EnableWebMvcSecurity
@EnableGlobalMethodSecurity(prePostEnabled=true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter{

    // Inject applicationEventPublisher
    @Inject
    private ApplicationEventPublisher applicationEventPublisher;

    @Autowired
    private CustomUserDetailsService userDetailsService;

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth
            // configure a auth event publisher
            .authenticationEventPublisher(new DefaultAuthenticationEventPublisher(applicationEventPublisher))
            .userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
    }

    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf().disable()
            .formLogin()
                .and()
            .httpBasic();
    }
}

通过这些更改，我的事件监听器能够接收身份验证失败事件。 这是 spring-security 4.0.2.RELEASE 和 spring-boot 1.2.5.RELEASE

希望对您有所帮助。
