logging - Spring Security 日志记录访问被拒绝异常

Question

我有一个带有 Spring Security 的应用程序，它目前不记录访问被拒绝的异常。我试图弄清楚我需要在我的 log4j 配置中更改什么设置才能记录访问被拒绝的异常。

我目前使用的是默认 org.springframework.security.web.access.AccessDeniedHandlerImpl作为我的 AccessDeniedHandler(带有一个用于 errorPage 的参数)。我是否需要创建一个替代品或从现有的 AccessDeniedHandler 继承？或者是否有像 logExceptions = true 这样的设置可以添加到 AccessDeniedHandler 中？

或者是否有一些我需要更改的 log4j 记录器设置？我目前有以下设置:

log4j.logger.org.springframework.security=WARN

配置的日志级别太高。访问被拒绝的异常将记录在级别 DEBUG :

2018-07-18 16:15:09.802 DEBUG 30380 --- [           main] o.s.s.w.a.ExceptionTranslationFilter     : Access is denied (user is not anonymous); delegating to AccessDeniedHandler

所以添加一个日志规则，如 org.springframework.security.web.access=DEBUG看见了。
