log4j:WARN No appenders could be found for logger (org.springframework.core.env.StandardEnvironment)的解决

2023-06-08,,

报错：log4j:WARN No appenders could be found for logger (org.springframework.core.env.StandardEnvironment).

出错原因：缺少日志文件,主要是后面的原因org.springframework.core.env.StandardEnvironment

解决方案：在resource中添加对应的log4j.properties文件,文件内容为

log4j.rootLogger=DEBUG,A1
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%c]-[%p] %m%n

或者

# Configure logging for testing: optionally with log file
log4j.rootLogger=WARN, stdout
# log4j.rootLogger=WARN, stdout, logfile
 
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern= %d %p [%c] - %m%n
 
log4j.appender.logfile=org.apache.log4j.FileAppender
log4j.appender.logfile.File=target/spring.log
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern= %d %p [%c] - %m%n
