Log4j1.27配置日志输出级别不起效

起因：构建独立版本debezuim使用时，日志一直打印debug信息。

原因：包冲突问题，进行排包操作。

参考log4j日志级别配置完成后不生效系统一直打印debug日志_log4j不起作用-CSDN博客

1、application.properties

logging.config=classpath:log4j.properties

2、log4j.properties 配置打印error日志，因依赖jar中已打印debug，所以升级打印级别，识别有效信息。

# 设置根日志级别
#log4j.rootLogger=DEBUG, stdout, R
log4j.rootLogger=ERROR, stdout, R

# 标准输出Appender配置
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

# 文件输出Appender配置
log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.File=logs/app.log
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

3、查看系统mvn依赖树：

mvn dependency:tree

首先 mvn dependency:tree 检查，打印如下：

确实存在logback包，在Springboot自带的依赖里。

通过mvn dependency:tree 查下系统的依赖树，检查下是否存在logback的依赖包，如果发现有logback-classic logback-core之类的包，从依赖树的上层过滤掉之后再看下，系统日志打印级别就会正常了

4、pom中操作排包 exclusions标签：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <!--排除，不包含-->
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </exclusion>
    </exclusions>
</dependency>

相关maven命令和排包可以参考

排包后打印：成功去除logback.jar。
