spring boot 日志配置

一、properties/yml 文件配置

logging:
  level:
    com.vincent.mapper: debug #日志级别
  file:
    path: C:\Users\Administrator\Desktop\proj\hr-sys\sys-server\logs  #日志路径

在C:\Users\Administrator\Desktop\proj\hr-sys\sys-server\logs 路径下将能看到spring.log 日志文件，该日志文件是spring boot 的默认文件名。

二、日志级别每天一个文件

resources 目录下新建logback.xml

<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
    <!--输出日志格式-->
    <appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>
                %d - %msg%n
            </pattern>
        </layout>
    </appender>
    <!--只保存info日志-->
    <appender name="fileInfoLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>INFO</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
        <encoder>
            <pattern>
                %d - %msg%n
            </pattern>
        </encoder>
        <!--滚动输出策略-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--路径-->
            <fileNamePattern>C:/Users/Administrator/Desktop/proj/hr-sys/sys-server/logs/info/info.%d.log</fileNamePattern>
        </rollingPolicy>
    </appender>

    <!--只保存warn日志-->
    <appender name="fileWarnLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>WARN</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
        <encoder>
            <pattern>
                %d - %msg%n
            </pattern>
        </encoder>
        <!--滚动输出策略-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--路径-->
            <fileNamePattern>C:/Users/Administrator/Desktop/proj/hr-sys/sys-server/logs/warn/warn.%d.log</fileNamePattern>
        </rollingPolicy>
    </appender>

    <!--只保存error日志-->
    <appender name="fileErrorLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>ERROR</level>
        </filter>
        <encoder>
            <pattern>
                %d - %msg%n
            </pattern>
        </encoder>
        <!--滚动输出策略-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--路径-->
            <fileNamePattern>C:/Users/Administrator/Desktop/proj/hr-sys/sys-server/logs/error/error.%d.log</fileNamePattern>
        </rollingPolicy>
    </appender>

    <root level="info">
        <appender-ref ref="consoleLog"/>
        <appender-ref ref="fileInfoLog"/>
        <appender-ref ref="fileWarnLog"/>
        <appender-ref ref="fileErrorLog"/>
    </root>
</configuration>

启动项目将在日志目录下看到分类的日志文件，文件夹内部将是已时间命名的日志文件。
