log4j配置未写入应用程序日志

Question

我通过将log4j.properties文件放在src/main/resources/log4j.properties中成功配置了log4j配置无法使用以下配置打印应用程序日志。

log4j.rootLogger=INFO, stdout, fileAppender
log4j.logger.org.springframework=INFO
log4j.logger.com.myPackage=TRACE, fileAppender
log4j.logger.org.hibernate=INFO
log4j.logger.org.apache=DEBUG
# Redirect log messages to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
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
### File - fileAppender
log4j.appender.fileAppender=org.apache.log4j.FileAppender
log4j.appender.fileAppender.File=./logs/myapp.log
log4j.appender.fileAppender.Append=false
log4j.appender.fileAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.fileAppender.layout.ConversionPattern=%r; %d; [%t]; %p; %c; %x; - %m%n

应用类别：

package com.myPackage.config
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
@Configuration
@Profile("dev")
public class DevDataSourceConfig {
private static final Logger logger = LogManager.getLogger(DevDataSourceConfig.class);

@Bean(name="dataSource")
public DataSource getDataSource() { 
logger.error("=================Dev environment, Entered into dataasource method===============");
logger.debug("=================Dev environment, Entered into dataasource method===============");
logger.info("=================Dev environment, Entered into dataasource method===============");
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(driverClassName); 
dataSource.setUrl(jdbcUrl);
dataSource.setUsername(username);
dataSource.setPassword(password);
return dataSource;
}
}

配置了log4j.logger.com.myPackage=TRACE，但从上面的日志中，只有错误日志正在打印。不确定，为什么。有人能帮忙吗。

Answer 1

1. 您的配置语法适用于Log4j 1.x，而不是Log4j2
2. 配置文件的名称适用于Log4j 1.x，而不是Log4j2
3. 您已将所有SLF4J调用路由到log4j 1.x
4. 您已将Commons Logging路由到SLF4J

考虑到所有这些，Log4j2将只使用其默认配置，即将错误记录到控制台。如果你想使用Log4j 2，你应该

1. 不将commons日志记录从Spring依赖项中排除
2. 将jcl-over-slf4j替换为log4j-jcl
3. 将slf4j-log4j12替换为log4j-1.2-api
4. 请使用有效的log4j 2.x配置
