shiro自定义authc过滤器的问题

配置了

过滤器代码如下
public class FormAuthenticationCaptchaFilter extends FormAuthenticationFilter {
public static final String DEFAULT_CAPTCHA_PARAM = ""captcha"";

private String captchaParam = DEFAULT_CAPTCHA_PARAM;public String getCaptchaParam() {    return captchaParam;}protected String getCaptcha(ServletRequest request) {    return WebUtils.getCleanParam(request getCaptchaParam());}protected AuthenticationToken createToken(ServletRequest request ServletResponse response) {    String username = getUsername(request);    String password = getPassword(request);    String captcha = getCaptcha(request);    boolean rememberMe = isRememberMe(request);    return new UsernamePasswordCaptchaToken(username            password rememberMe captcha);} // 验证码校验   protected void doCaptchaValidate( HttpServletRequest request       UsernamePasswordCaptchaToken token ){        String captcha = (String) SecurityUtils.getSubject().getSession()        .getAttribute(CaptchaServlet.KEY_CAPTCHA);      if( captcha!=null &&          !captcha.equalsIgnoreCase(token.getCaptcha()) ){          throw new CaptchaException (""验证码错误！"");       }    } // 认证   protected boolean executeLogin(ServletRequest request       ServletResponse response) throws Exception {        UsernamePasswordCaptchaToken token = (UsernamePasswordCaptchaToken)createToken(request response);       try {          doCaptchaValidate( (HttpServletRequest)requesttoken );          Subject subject = getSubject(request response);          subject.login(token);          return onLoginSuccess(token subject request response);       } catch (AuthenticationException e) {          return onLoginFailure(token e request response);       }    } 

}
但是在访问相应 url的时候再过滤器中debug进不去
