Spring自定义AuthenticationFailureHandler

Question

我已经尝试了一整天,让我的自定义身份验证失败处理程序与Spring 3.1.3一起使用.

我认为它配置正确

<http use-expressions="true" disable-url-rewriting="true">
    <intercept-url pattern="/rest/login" access="permitAll" />
    <intercept-url pattern="/rest/**" access="isAuthenticated()" />
    <intercept-url pattern="/index.html" access="permitAll" />
    <intercept-url pattern="/js/**" access="permitAll" />
    <intercept-url pattern="/**" access="denyAll" />
    <form-login username-parameter="user" password-parameter="pass" login-page="/rest/login"
        authentication-failure-handler-ref="authenticationFailureHandler"  />
</http>
<beans:bean id="authenticationFailureHandler" class="LoginFailureHandler" />

我的实现是这样的

public class LoginFailureHandler implements AuthenticationFailureHandler {
    private static final Logger log = LoggerFactory.getLogger(LoginFailureHandler.class);

    public LoginFailureHandler() {
        log.debug("I am");
    }

    @Autowired
    private ObjectMapper customObjectMapper;

    @Override
    public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response,
            AuthenticationException exception) throws IOException, ServletException {
        log.debug("invalid login");
        User user = new User();
        user.setUsername("invalid");
        try (OutputStream out = response.getOutputStream()) {
            customObjectMapper.writeValue(out, user);
        }
    }

}

在控制台中,我看到了

2013-04-11 14:52:29,478 DEBUG LoginFailureHandler - I am

所以它被加载了.

使用错误的用户名或密码,当抛出BadCredentialsException时,我看不到无效登录.

永远不会调用Method of onheuthenticationFailure.

相反,服务会一次又一次地将浏览器重定向到/ rest/login ...

这种情况发生在调试模式中

我的错误在哪里？
