解决：1 在Create a Java project时，一定要选Project layout中的Create separate source and output foldedrs 解决找不到hibernate.cfg.xml
2 在src下在创建log4j.properties 解决log4j:WARN
内容为：
log4j.rootLogger=debug,A1,R
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-ddHH:mm:ss}[%c]-[%p]%m-(:%L)%n
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=D:/workspace/DemoHibernate/HibernateDemoLog.log
log4j.appender.R.MaxFileSize=100KB
log4j.appender.R.MaxBackupIndex=1
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%-d{yyyy-MM-ddHH:mm:ss}[%c]-[%p]%m-(:%L)%n
修改DemoHibernateTest.java如下：
publicclass DemoHibernateTest {
