SpringBoot使用log4j给日志落盘

写磁盘，使用log4j
    但是springboot，内置的日志是logging
    所以，1.需要把logging去掉 2.换成log4j

*  把logging去掉  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQ2NTQ4ODU1_size_16_color_FFFFFF_t_70_pic_center]

<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>

*  2.添加log4j

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-log4j</artifactId>
                <version>1.3.8.RELEASE</version>
            </dependency>

在resources下创建log4j.properties

# 写到控制台
    log4j.appender.donglin.MyConsole=org.apache.log4j.ConsoleAppender
    log4j.appender.donglin.MyConsole.target=System.out
    log4j.appender.donglin.MyConsole.layout=org.apache.log4j.PatternLayout
    log4j.appender.donglin.MyConsole.layout.ConversionPattern=%d{ yyyy-MM-dd HH:mm:ss} %6p (%c:%M) - %m%n
    
    # 写到磁盘
    log4j.appender.donglin.File=org.apache.log4j.DailyRollingFileAppender
    # 部署到linux的时候，这个目录需要更改到liunx上可用的目录
    log4j.appender.donglin.File.file=F:/app1015.log
    log4j.appender.donglin.File.DatePattern='.'yyyy-MM-dd
    log4j.appender.donglin.File.layout=org.apache.log4j.PatternLayout
    log4j.appender.donglin.File.layout.ConversionPattern=%m%n
    
    # 哪些东西往外写   com.donglin.gmalllogger.controller.LoggerController这是全类名
    log4j.logger.com.donglin.gmalllogger.controller.LoggerController=info,donglin.File,donglin.MyConsole

日志落盘

/** * 日志的落盘，使用的log4j来完成 * @param log */
        private Logger logger = LoggerFactory.getLogger(LoggerController.class);
        private void saveToFile(String log) { 
            logger.info(log);
    
        }
