15      * GenerationType.AUTO 主键由程序控制
16      * GenerationType.TABLE 使用一个特定的数据库表格来保存主键

# Root logger option
log4j.rootLogger=INFO, console
log4j.logger.com.ch.demo=INFO, console

# Direct log messages to console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.Target=System.out
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{HH:mm}| %p | %F %L | %m%n

# direct messages to file hibernate.log
# log4j.logger.org.hibernate=DEBUG, hibernate
log4j.appender.hibernate=org.apache.log4j.RollingFileAppender
log4j.appender.hibernate.File=hibernate.log
log4j.appender.hibernate.layout=org.apache.log4j.PatternLayout

# Hibernate主要的类别如下：

# 1）org.hibernate.SQL
# 日志输出所有Hibernate执行的SQL DML语句
log4j.logger.org.hibernate.SQL=debug 

# 2）org.hibernate.type
# 日志输出所有的JDBC参数

# 3）org.hibernate.transaction
# 日志输出所有活动相关的事务

# 4）org.hibernate.jdbc
# 日志输出所有的JDBC资源采集

# 5）org.hibernate.tool.hbm2ddl
# 日志输出所有Hibernate执行的SQL DDL语句
log4j.logger.org.hibernate.tool.hbm2ddl = Debug

# 6）org.hibernate
# 日志输出所有的Hibernate信息

# 如果指定日志输出类别为org.hibernate.SQL，那么将会输出SQL语句。但是，还有一种更简单的查看SQL语句的方法，只需简单地设置show_sql参数为true。
