Print Class Name, Method name and line number using Logger's info()
提问by amal
I already configured logback file to get classname, method name and line number.
我已经配置了 logback 文件来获取类名、方法名和行号。
<pattern> %d{HH:mm:ss.SSS} [%thread] %-5level %class{36}.%M %L - %msg%n </pattern>
I want to print log message when entering and existing method. How can i do that within the class using info() method. I used the code below. But it didnt print what i wanted.
我想在输入和现有方法时打印日志消息。我如何使用 info() 方法在课堂上做到这一点。我使用了下面的代码。但它没有打印我想要的。
I use org.slf4j.Logger and Logback logging
我使用 org.slf4j.Logger 和 Logback 日志记录
LOG.info("Entering " + );
This is what I got :
这就是我得到的：
14:41:48.097 [main] INFO c.a.j.orgchart.CsvPersonReader - Entering
I want to print something like this:
我想打印这样的东西：
14:41:48.097 [main] INFO c.a.j.orgchart.CsvPersonReader.[MethodName] [Linenumber] - Entering

logging.pattern.console=%14date{dd.MM.yyyy kk:mm:ss.SSS} [%1level] %30.30logger{1}\.%replace(%replace(%replace(%caller{3..4}){'[\n\r]',''}){'\(.+\)$','()'}){'^.+\.',''} : %msg%n
Above pattern outputs result like below:
以上模式输出结果如下：
10.05.2019 08:35:05.337 [INFO] epositoryConfigurationDelegate.forEach() : Bootstrapping Spring Data repositories in DEFAULT mode.
...
Here's another option if you want to printout little a bit polished version of it.
如果您想打印出稍微改进的版本，这是另一种选择。
logging.pattern.console=%14date{dd.MM.yyyy kk:mm:ss.SSS} [%1level] %40.40logger{0}\.%-35.35replace(%replace(%replace(%caller{3..4}){'[\n\r]',''}){'\(.+\)$','()'}){'^.+\.',''} : %msg%n
Output looks like this:
输出如下所示：
10.05.2019 08:45:57.228 [DEBUG] RepositoryConfigurationDelegate.forEach() : Bootstrapping Spring Data repositories in DEFAULT mode.
10.05.2019 08:45:59.651 [INFO] RepositoryConfigurationDelegate.forEach() : Finished Spring Data repository scanning in 384ms. Found 3 repository interfaces.

Just keep in mind that "...Generating the caller class information is not particularly fast. ..."
请记住“...生成调用者类信息不是特别快。...”
