logback使用

ゝ一世哀愁。 2022-09-21 15:29 162阅读 0赞

1、需要引入maven配置  
  
ch.qos.logback  
logback-classic  
1.0.0  
这个会依赖slf4j-api和logback-core。  
  
ch.qos.logback  
logback-access  
1.1.5  
  
所有的jar包  
logback-access-1.0.0.jar  
logback-classic-1.0.0.jar  
logback-core-1.0.0.jar  
slf4j-api-1.6.0.jar

2、LoggerFactory.getLogger()方法可以传递两种参数。自己起的名字和类.class。主要在打印的日志里有所区分

3、logback有默认的配置，会读取项目里的logback.xml和logback-test.xml配置文件

4、配置文件里可以设置到类级别的打印日志

5、appender里加上filter可以使文件里只打印改类型的日志

6、通过定义包来打印框架的日志

7、xml配置里如果使用变量来定义参数，那么就得,切记加

8、打印info级别日志时如果getLogger()参数是自定义的string的话，可能会引起无法输出日志的问题
