• Spring logger 配置


    1. logback-spring.xml 

    <?xml version="1.0" encoding="UTF-8"?>
    <configuration scan="true" scanPeriod="60 seconds" debug="false">
        <contextName>logback</contextName>
        <!--输出到控制台-->
        <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
            <encoder>
                <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger -%msg%n</pattern>
            </encoder>
        </appender>
    
        <appender name="INFO_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <File>C:gather-logscrm-info.log</File>
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <fileNamePattern>C:gather-logsserver-info-%d{yyyyMMdd}.log.%i</fileNamePattern>
                <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                    <maxFileSize>5MB</maxFileSize>
                </timeBasedFileNamingAndTriggeringPolicy>
                <maxHistory>2</maxHistory>
            </rollingPolicy>
            <layout class="ch.qos.logback.classic.PatternLayout">
                <Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger -%msg%n</Pattern>
            </layout>
            <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
                <!--格式化输出:%d表示日期,%thread表示线程名,%-5level:级别从左显示5个字符宽度%msg:日志消息,%n是换行符-->
                <pattern>%date{yyyy-MM-dd HH:mm:ss} | %highlight(%-5level) | %boldYellow(%thread) | %boldGreen(%logger) |
                    %msg%n
                </pattern>
            </encoder>
    
        </appender>
    
        <appender name="ERROR_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
                <level>ERROR</level>
            </filter>
            <File>C:gather-logscrm-error.log</File>
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <fileNamePattern>C:gather-logsserver-error-%d{yyyyMMdd}.log.%i
                </fileNamePattern>
                <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                    <maxFileSize>5MB</maxFileSize>
                </timeBasedFileNamingAndTriggeringPolicy>
                <maxHistory>2</maxHistory>
            </rollingPolicy>
            <layout class="ch.qos.logback.classic.PatternLayout">
                <Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger -%msg%n
                </Pattern>
            </layout>
        </appender>
    
        <!--    <logger name="com.example.demo1.controller" level="INFO">-->
    
        <!--    </logger>-->
    
        <root level="INFO">
            <appender-ref ref="console"/>
            <appender-ref ref="INFO_FILE"/>
            <appender-ref ref="ERROR_FILE"/>
        </root>
    
    
        <!-- TRACE, DEBUG, INFO, WARN, ERROR, ALL 和 OFF -->
        <logger name="org.springframework" level="DEBUG" additivity="true"/>
    
    
        <logger name="org.apache" level="OFF"/>
        <logger name="com.alibaba" level="OFF"/>
        <!-- 如果这里设置了additivity=true 代码打印信息向上传递,将打印信息传递到root ,并且自己的appender-ref 也会打印,这样就是打印了俩次日志-->
        <logger name="com.example.demo1" level="OFF" additivity="false">
            <appender-ref ref="console"/>
        </logger>
    </configuration>
    

     (1) 

        <contextName>logback</contextName>
        <!-- name的值是变量的名称,value的值时变量定义的值。通过定义的值会被插入到logger上下文中。定义后,可以使“${}”来使用变量。 -->
        <property name="log.path" value="G:/logs/pmp" />
    

     (2)

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

    scan: 当此属性设置为true时,配置文档如果发生改变,将会被重新加载,默认值为true 

    scanPeriod: 设置监测配置文档是否有修改的时间间隔,如果没有给出时间单位,默认单位是毫秒。当scan为true时,此属性生效。默认的时间间隔为1分钟。

    debug: 当此属性设置为true时,将打印出logback内部日志信息,实时查看logback运行状态。默认值为false。 

        

    2. 设置Logger 

     <logger name="com.example.demo1" level="INFO" additivity="true">
            <appender-ref ref="console"/>
     </logger>
    

      (1)logger 设置 level 时,则根据level 过滤日志信息,如果没有设置level ,则继承root的level。

      (2)logger 的additivity属性,如果设置为true,则会将日志信息向上传递给root,同时也执行自己的<appender-ref> 这里会出现打印2次的现象。

          如下:

       

    package com.example.demo1.controller;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @Controller
    public class MyController {
    
        private static Logger logger= LoggerFactory.getLogger(MyController.class);
    
        @RequestMapping("/getOut")
        @ResponseBody
        public String getBody(){
    
            logger.info("-----------info");
            logger.debug("----------debug");
            logger.warn("-----------warn");
            logger.error("----------error");
            return "body";
        }
    }
    

      

     3. appender  

     

        <appender name="INFO_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <File>C:gather-logscrm-info.log</File>
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <fileNamePattern>C:gather-logsserver-info-%d{yyyyMMdd}.log.%i</fileNamePattern>
                <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                    <maxFileSize>5MB</maxFileSize>
                </timeBasedFileNamingAndTriggeringPolicy>
                <maxHistory>2</maxHistory>
            </rollingPolicy>
            <layout class="ch.qos.logback.classic.PatternLayout">
                <Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger -%msg%n</Pattern>
            </layout>
            <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
                <!--格式化输出:%d表示日期,%thread表示线程名,%-5level:级别从左显示5个字符宽度%msg:日志消息,%n是换行符-->
                <pattern>%date{yyyy-MM-dd HH:mm:ss} | %highlight(%-5level) | %boldYellow(%thread) | %boldGreen(%logger) |
                    %msg%n
                </pattern>
            </encoder>
    
        </appender>
    

      (1)  日志打印保存的路径  

       <File>C:gather-logscrm-info.log</File>
    

      (2) 日志文件的命名方式 如果: server-info-20190617.log.1   

    <fileNamePattern>C:gather-logsserver-info-%d{yyyyMMdd}.log.%i</fileNamePattern>
    

      (3) 日志的最大设置为5M ,如果大于5M ,则归档,创建文件如:  server-info-20190617.log.2

    <maxFileSize>5MB</maxFileSize>
    

     (4)日志的保存时间 2天 

      <maxHistory>2</maxHistory>
    

     (5)Logger 的输入格式 eg: 

      

    <layout class="ch.qos.logback.classic.PatternLayout">
         <Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger -%msg%n</Pattern>
    </layout>
    <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
        <!--格式化输出:%d表示日期,%thread表示线程名,%-5level:级别从左显示5个字符宽度%msg:日志消息,%n是换行符-->
         <pattern>%date{yyyy-MM-dd HH:mm:ss} | %highlight(%-5level) | %boldYellow(%thread) | %boldGreen(%logger) | %msg%n
         </pattern>
     </encoder>    
    

    4. 配置log的dev prd环境

     <springProfile name="dev">
            <property name="log.path" value="/Users/guoxiwang/software/idea/log/dev" />
        </springProfile>
        <springProfile name="prd">
            <property name="log.path" value="/Users/guoxiwang/software/idea/log/prd" />
        </springProfile>
    

     

     <appender name="DEBUG_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <!-- 正在记录的日志文档的路径及文档名 -->
            <file>${log.path}/web_debug.log</file>
            <!--日志文档输出格式-->
            <encoder>
                <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
                <charset>UTF-8</charset> <!-- 设置字符集 -->
            </encoder>
            <!-- 日志记录器的滚动策略,按日期,按大小记录 -->
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <!-- 日志归档 -->
                <fileNamePattern>${log.path}/web-debug-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
                <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                    <maxFileSize>1MB</maxFileSize>
                </timeBasedFileNamingAndTriggeringPolicy>
                <!--日志文档保留天数-->
                <maxHistory>15</maxHistory>
            </rollingPolicy>
            <!-- 此日志文档只记录debug级别的 -->
            <filter class="ch.qos.logback.classic.filter.LevelFilter">
                <level>debug</level>
                <onMatch>ACCEPT</onMatch>
                <onMismatch>DENY</onMismatch>
            </filter>
        </appender>
