maven 项目 springmvc spring 使用SLF4J和 LogBack 做为日志 xml里配置即可

pom.xl 里添加依赖包：

  <!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-api -->

    <dependency>

       <groupId>org.slf4j</groupId>

      <artifactId>slf4j-api</artifactId>

       <version>1.7.25</version>

     </dependency>

         <!-- https://mvnrepository.com/artifact/log4j/log4j -->

    <dependency>

      <groupId>log4j</groupId>

      <artifactId>log4j</artifactId>

      <version>1.2.17</version>

    </dependency>

        <!-- https://mvnrepository.com/artifact/org.slf4j/jcl-over-slf4j -->

     <dependency>
   <groupId>org.slf4j</groupId>
   <artifactId>jcl-over-slf4j</artifactId>
   <version>1.7.25</version>

    </dependency>

           <!-- https://mvnrepository.com/artifact/ch.qos.logback/logback-classic -->

    <dependency>

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

       <artifactId>logback-classic</artifactId>

      <version>1.2.3</version>

       <!--<scope>test</scope> -->

    </dependency>

           <!-- https://mvnrepository.com/artifact/ch.qos.logback/logback-core -->

   <dependency>
 <groupId>ch.qos.logback</groupId>
  <artifactId>logback-core</artifactId>
  <version>1.2.3</version>

   </dependency>

           <!-- https://mvnrepository.com/artifact/ch.qos.logback/logback-access -->
<dependency>
   <groupId>ch.qos.logback</groupId>
   <artifactId>logback-access</artifactId>
   <version>1.2.3</version>
</dependency>

在src/main/resource目录下创建 ：logback.xml 即可

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

<configuration scan="true" scanPeriod="1 seconds">

   <contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator">

       <resEYJUL>true</resEYJUL>

   </contextListener>

   <jmxConfigurator/>

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

   

   <encoder>

    <parttern>logbak: %d{HH:mm:ss.SSSS} %loger{36} - %msg%n</parttern>

   </encoder>

   </appender>

   <logger name="org.springframework.web" level="DEBUG"></logger>

   <root level="info">

       <appender-ref ref="console"/>

   </root>

</configuration>
