springboo 添加logback日志

springboot默认引入logback相关的jar包

1、在 Application.properties里添加

logging.config=classpath:logback-spring.xml  

注：当文件名为logback-spring.xml时 不需要配置logging.config

logback日志基础配置可以参照官方

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml" />
    <logger name="sample.logback" level="DEBUG" />
    <springProfile name="staging">
        <logger name="sample.logback" level="TRACE" />
    </springProfile>
</configuration>

"sample.logback"是包名

logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml"/>
    <!-- 文件输出格式 -->
    <property name="PATTERN" value="%-12(%d{yyyy-MM-dd HH:mm:ss.SSS}) |-%-5level [%thread] %c [%L] -| %msg%n"/>
    <!-- test文件路径 -->
    <property name="TEST_FILE_PATH" value="F:/vrv/logs/hrmis"/>
    <!-- prod文件路径 -->
    <property name="PRO_FILE_PATH" value="/vrv/logs/hrmis" />
    <!-- 开发环境 -->
    <springProfile name="dev">
        <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
            <encoder>
                <pattern>${PATTERN}</pattern>
            </encoder>
        </appender>
        <logger name="com.example" level="DEBUG"/>
        <root level="info">
            <appender-ref ref="CONSOLE"/>
        </root>
    </springProfile>
    <!-- 测试环境 -->
    <springProfile name="test">
        <!-- 每天产生一个文件 -->
        <appender name="TEST-FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <!-- 文件路径 -->
            <file>${TEST_FILE_PATH}</file>
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <!-- 文件名称 -->

                <!-- 文件最大保存历史数量 -->
                <MaxHistory>100</MaxHistory>
            </rollingPolicy>
            <layout class="ch.qos.logback.classic.PatternLayout">
                <pattern>${PATTERN}</pattern>
            </layout>
        </appender>
        <root level="info">
            <appender-ref ref="TEST-FILE"/>
        </root>
    </springProfile>
    <!-- 生产环境 -->
    <springProfile name="prod">
        <appender name="PROD_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <file>${PRO_FILE_PATH}</file>
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <fileNamePattern>${PRO_FILE_PATH}/warn.%d{yyyy-MM-dd}.log</fileNamePattern>

            </rollingPolicy>
            <layout class="ch.qos.logback.classic.PatternLayout">
                <pattern>${PATTERN}</pattern>

        <root level="warn">
            <appender-ref ref="PROD_FILE" />
        </root>
    </springProfile>
</configuration>

以下是扩展配置,仅作参考：

<configuration scan="true" scanPeriod="60 seconds" debug="false">  

    <include resource="org/springframework/boot/logging/logback/defaults.xml" />

    <property name="LOG_HOME" value="/var/log" />

    <!-- 彩色日志格式 -->
    <property name="CONSOLE_LOG_PATTERN" value="${CONSOLE_LOG_PATTERN:-%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}" />
    <!-- Console 输出设置 -->

关于Spring-Boot给出的配置方式如下：

# LOGGING
logging.config= # Location of the logging configuration file. For instance `classpath:logback.xml` for Logback

logging.exception-conversion-word=%wEx # Conversion word used when logging exceptions.

logging.file= # Log file name. For instance `myapp.log`

logging.level.*= # Log levels severity mapping. For instance `logging.level.org.springframework=DEBUG`

logging.path= # Location of the log file. For instance `/var/log`

logging.pattern.console= # Appender pattern for output to the console. Only supported with the default logback setup.

logging.pattern.file= # Appender pattern for output to the file. Only supported with the default logback setup.

logging.pattern.level= # Appender pattern for log level (default %5p). Only supported with the default logback setup.

logging.register-shutdown-hook=false # Register a shutdown hook for the logging system when it is initialized.
