我有一段代码-

    @PropertySource(value = "classpath:securityConfig.properties", ignoreResourceNotFound = true)
    @Controller
    public class IndexController {
        private static final String LOGIN_PAGE           = "login";
        private static final String HOME_PAGE            = "home";
        private static final String LOBBY_PAGE           = "lobby";
        private static final String FORGOT_USER_PAGE     = "forgotUserName";
        private static final String FORGOT_PASSWORD_PAGE = "forgotPassWord";

        @ConditionalOnProperty(name = "auth.mode", havingValue = "fixed")
        @PreAuthorize("isAnonymous()")
        @RequestMapping(method = RequestMethod.GET, value = { "/login" })
        public String getIndexPage() {
            return LOGIN_PAGE;
        }
}

但是，ConditionalOn注释不能按预期工作。我不想控制器执行，如果auth.mode是比其他任何东西fixed。注意-
auth.mode已在securityConfig.properties文件中

我想念什么吗？可能是在课堂上的注释？
