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

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

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

解決方案：在resource中添加對應的log4j.properties文件,文件內容為

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
