解决log4j:WARN No appenders could be found for logger

这个问题是因为我们的log4j.properties文件配置不够完整，所以我们给它配置齐了就不会再出现这个问题。
log4j.properties不完整配置如下：

log4j.rootLogger=DEBUG, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%c{1} - %m%n

log4j.logger.java.sql.PreparedStatement=DEBUG
