Grails 日志记录自动注入
Grails logging auto inject
我使用 grails 3.0.2 和 logback。我如何在我的代码中使用这个记录器,我能以某种方式自动注入它吗,比如 grails 2.x 中的 log.debug() 正在使用 org.apache.commons.logging.Log?
在您的 class 上添加 @Slf4j
注释。
This local transform adds a logging ability to your program using
LogBack logging. Every method call on a unbound variable named log
will be mapped to a call to the logger. For this a log field will be
inserted in the class. If the field already exists the usage of this transform
will cause a compilation error. The method name will be used to determine
what to call on the logger.
log.name(exp)
is mapped to
if (log.isNameLoggable() {
log.name(exp)
}
Here name is a place holder for info, debug, warning, error, etc.
If the expression exp is a constant or only a variable access the method call will
not be transformed. But this will still cause a call on the injected logger.
