今天考试的时候出了个错误  把我搞的蛋疼了半天 在最后关头找到了 

在配置完Hibernate,运行时出现错误:log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).

log4j:WARN Please initialize the log4j system properly.

 

解决办法如下:

在src下面新建file名为log4j.properties内容如下:

### direct log messages to stdout ###

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{ABSOLUTE} %5p %c{1}:%L - %m%n

### root logger option ###

log4j.rootLogger=warn, stdout

### Hibernate logging options ###

log4j.logger.net.sf.hibernate=info

### log JDBC bind parameters ###

log4j.logger.net.sf.hibernate.type=info

### log PreparedStatement cache activity ###

log4j.logger.net.sf.hibernate.ps.PreparedStatementCache=info
