日志配置ogback slf4j

日志配置

有日志然后可以打印一切(包括sql，异常，普通信息) logback取代log4j的理由

logback可以在里面切换log4j，slf4j内含log4j（默认就是这个），集成了slf4j之后就用slf4j（根据你加入的jar包自动识别切换）

 

logback日志配置：

 

1，下载jar

<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>

 

2，web.xml配置

<context-param>

<param-name>logbackConfigLocation</param-name>

<param-value>classpath:config_log/logback.xml</param-value>

</context-param>

<listener>

<listener-class>ch.qos.logback.ext.spring.web.LogbackConfigListener</listener-class>

</listener>

 

3，logback.xml配置

 

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

<configuration debug="true" scan="true">

 

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

        <resetJUL>true</resetJUL>

    </contextListener>

 

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

        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">

            <!-- <pattern>%.-1level|%-40.40logger{0}|%msg%n</pattern> -->

            <!--<pattern>%d{yyyy/MM/dd-HH:mm:ss} %-5level [%thread] %class{5}:%line>>%msg%n</pattern> -->

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

        </encoder>

    </appender>

 

    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">

        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

            <fileNamePattern>${catalina.base}/logs/esteelds/esteelLogFile_%d{yyyy-MM-dd}.%i.log</fileNamePattern>

            <minIndex>1</minIndex>

            <maxIndex>100</maxIndex>

            <maxHistory>30</maxHistory>

            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">

                <!-- or whenever the file size reaches 100MB -->

                <maxFileSize>5MB</maxFileSize>

            </timeBasedFileNamingAndTriggeringPolicy>

        </rollingPolicy>

<!--日志文件最大的大小-->

        <encoder>

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

        </encoder>

    </appender>

    <logger name="org.logicalcobwebs" level="ERROR"  />

    <logger name="com.esteel" level="INFO" />

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

    <logger name="org.springframework.jdbc" level="INFO" />

    <logger name="org.mybatis" level="INFO" />

    <logger name="org.springframework.beans" level="INFO" />

    <logger name="com.esteel.mybatis" level="INFO" />

    <!--  <logger name="org.apache.ibatis" level="DEBUG">///////////////////////mysql打印日志

<appender-ref ref="STDOUT"/>

</logger>

 

<logger name="java.sql" level="debug">

   <appender-ref ref="STDOUT"/>

</logger>  -->

    <root level="INFO">

        <appender-ref ref="STDOUT" />

        <appender-ref ref="FILE" />

    </root>

</configuration>

 

 

 

4，应用：

（1）打印sql

logback.xml加：

<logger name="org.apache.ibatis" level="DEBUG">///////////////////////mysql打印日志

<appender-ref ref="STDOUT"/>

</logger>

 

<logger name="java.sql" level="debug">

   <appender-ref ref="STDOUT"/>

</logger>

 

mybatis-config.xml加

<setting name="logImpl" value="STDOUT_LOGGING"/>///其实这个即可

 

 

（2）在Java中硬编码打印

package com.stu.system.action; 

 

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

 

public class BlogAction{

   //定义一个全局的记录器，通过LoggerFactory获取

   private final static Logger logger = LoggerFactory.getLogger(BlogAction.class); 

   /**

   * @param args

   */

  public static void main(String[] args) {

    logger.info("logback 成功了");

    logger.error("logback 成功了");

  }

}
