摘要：项目日志文件配置,springboot项目配置log4j日志框架

1、排除默认的logback包依赖，加入log4j日志依赖

log4j日志包的版本信息

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter</artifactId>
                <exclusions>
                    <exclusion>
                        <groupId>org.springframework.boot</groupId>
                        <artifactId>spring-boot-starter-logging</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>
    
    
            <dependency>
                <groupId>log4j</groupId>
                <artifactId>log4j</artifactId>
                <version>${log4j.version}</version>
            </dependency>
    
            <dependency>
                <groupId>org.slf4j</groupId>
                <artifactId>slf4j-api</artifactId>
                <version>${slf4j.version}</version>
            </dependency>
    
            <dependency>
                <groupId>org.slf4j</groupId>
                <artifactId>slf4j-log4j12</artifactId>
                <version>${slf4j-log4j.version}</version>
            </dependency>

2、log4j.properties配置

下述配置来自网上

log4j.rootLogger=DEBUG,system,dailyFile
    
    log4j.appender.system=org.apache.log4j.ConsoleAppender
    log4j.appender.system.Target=System.out
    log4j.appender.system.layout=org.apache.log4j.PatternLayout
    log4j.appender.system.layout.ConversionPattern=%p %t %c - %m%n
    
    #日志级别
    #log4j.appender.dailyFile.Threshold=INFO
    # 每天产生一个日志文件(dailyFile)
    log4j.appender.dailyFile=org.apache.log4j.DailyRollingFileAppender
    #当天的日志文件全路径
    log4j.appender.dailyFile.File=D:/logs/sbd-log4j/b2i.log
    #服务器启动日志是追加，false：服务器启动后会生成日志文件把老的覆盖掉
    log4j.appender.dailyFile.Append=true
    #日志文件格式
    log4j.appender.dailyFile.layout=org.apache.log4j.PatternLayout  
    log4j.appender.dailyFile.layout.ConversionPattern=%-d{yyyy-MM-dd HH\:mm\:ss} [%c]-[%p] [%t] (%F\:%L) ->%m %n
    #设置每天生成一个文件名后添加的名称,备份名称：年月日.log
    log4j.appender.dailyFile.DatePattern='.'yyyy-MM-dd'.log'

3、效果

控制台

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dyb25neWFv_size_16_color_FFFFFF_t_70][]

硬盘文件，上述配置到了D:/logs/sbd-log4j
