  maven的porm.xml需要以下几个依赖

  <!-- sl4j -->

  <dependency>

  <groupId>org.slf4j</groupId>

  <artifactId>slf4j-api</artifactId>

  <version>1.7.10</version>

  </dependency>

  <dependency>

  <groupId>ch.qos.logback</groupId>

  <artifactId>logback-classic</artifactId>

  <version>1.1.2</version>

  </dependency>

  <dependency>

  <groupId>ch.qos.logback</groupId>

  <artifactId>logback-core</artifactId>

  <version>1.1.2</version>

  </dependency>

  
  

  logback.xml文件放到指定的文件夹目录下src/main/resources
  

  <?xml version="1.0" encoding="UTF-8"?>

  <configuration>

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">

  <!-- encoders are assigned the type ch.qos.logback.classic.encoder.PatternLayoutEncoder 

  by default -->

  <encoder>

  <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>

  </encoder>

  </appender>

  
  

  <root level="debug">

  <appender-ref ref="STDOUT" />

  </root>

  </configuration>

  
  

  测试类当中像老师那样调用即可

  private final Logger logger = LoggerFactory.getLogger(this.getClass());

  logger.info("s={}", s);
