1,p6spy.jar放入lib目录,spy.properties文件放入classes目录
2,spy.properties文件做下面的配置之后,可以把sql语句打印到控制台和文件:

# EXECUTION THRESHOLD PROPERTIES #
################################################################
# This feature applies to the standard logging of P6Spy. #
# While the standard logging logs out every statement #
# regardless of its execution time, this feature puts a time #
# condition on that logging. Only statements that have taken #
# longer than the time specified (in milliseconds) will be #
# logged. This way it is possible to see only statements that #
# have exceeded some high water mark. #
# This time is reloadable. #

# P6OUTAGE SPECIFIC PROPERTIES #
################################################################
# Outage Detection
#
# This feature detects long-running statements that may be indicative of
# a database outage problem. If this feature is turned on, it will log any
# statement that surpasses the configurable time boundary during its execution.
# When this feature is enabled, no other statements are logged except the long
# running statements. The interval property is the boundary time set in seconds.
# For example, if this is set to 2, then any statement requiring at least 2
# seconds will be logged. Note that the same statement will continue to be logged
# for as long as it executes. So if the interval is set to 2, and the query takes
# 11 seconds, it will be logged 5 times (at the 2, 4, 6, 8, 10 second intervals).

# DataSource replacement #

#################################################################
# DataSource properties #
# #
# If you are using the DataSource support to intercept calls #
# to a DataSource that requires properties for proper setup, #
# define those properties here. Use name value pairs, separate #
# the name and value with a semicolon, and separate the #
# pairs with commas. #
# #
# The example shown here is for mysql #
# #

#realdatasourceproperties=port;3306,serverName;myhost,databaseName;jbossdb,foo;bar
#################################################################
# JNDI DataSource lookup #
# #
# If you are using the DataSource support outside of an app #
# server, you will probably need to define the JNDI Context #
# environment. #
# #
# If the P6Spy code will be executing inside an app server then #
# do not use these properties, and the DataSource lookup will #
# use the naming context defined by the app server. #
# #
# The two standard elements of the naming environment are #
# jndicontextfactory and jndicontextproviderurl. If you need #
# additional elements, use the jndicontextcustom property. #
# You can define multiple properties in jndicontextcustom, #
# in name value pairs. Separate the name and value with a #
# semicolon, and separate the pairs with commas. #
# #
# The example shown here is for a standalone program running on #
# a machine that is also running JBoss, so the JDNI context #
# is configured for JBoss (3.0.4). #

注:貌似hibernate3.0以前是这样。
虽然在hibernate中有show_sql选项,但是显示出来的语句大多类似
select * from xxx where value=?
但是有时候我们需要得到完整的SQL语句,怎么办呢?使用P6SPY就可以完成这个任务
p6spy是一个开源软件,它可以跟踪任何使用jdbc的应用产生的数据库操作。特别适合于监控ejb服务器产生的 sql statements。
官方网址:http://www.p6spy.com/
目前p6spy 适用的应用服务器包括jboss, atg, orion, jonas, iplanet, weblogic, websphere, resin and tomcat.
下面我介绍一下p6spy在tomcat应用程序上安装的步骤:
(1)http://www.p6spy.com/download.html,下载zip包
(2)解压出p6spy.jar spy.properties两个文件
(3)将p6spy.jar 放入应用程序的WEB-INF/lib目录,将spy.properties放入WEB-INF/classes目录
(4)修改spy.properties
realdriver =com.mysql.jdbc.Driver 将这行前面的#去掉
logfile = c:/spy.log 修改一个你需要的日志文件名
(5)修改hibernate.xml,修改connection.driver_class的值为com.p6spy.engine.spy.P6SpyDriver
(6)重启tomcat
(7)这样在c:/下的spy.log记录了数据库的访问情况。
-----------------------------------------
1.下载附件的p6psy.jar以及spy.properties文件
2.将p6spy.jar放到应用的lib目录下,将spy.properties放到WEB-INF\classes目录下
3.修改spy.properties样本的第41行。改成需要的数据库信息
修改spy.properties样本的第54行 。改成需要的数据库信息
修改spy.properties样本的第168行,将spy.log放到比较好找的位置:
例如:logfile = E:/spy.log
4.驱动程序加载先后的问题解决
如果spy.log里出现
你的程序的数据库驱动名称 is a real driver in spy.properties, but it has been loaded before p6spy. p6spy will not wrap these connections. Either prevent the driver from loading, or try setting 'deregisterdrivers' to true in spy.properties
请把spy.properties文件里的deregisterdrivers=false改为deregisterdrivers=true,重新运行即可。
