我是靠谱客的博主机灵香菇，最近开发中收集的这篇文章主要介绍P6Spy应用:Hibernate显示真正SQL(1)，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

P6Spy和sping配合显示真正的SQL

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：

# MODULES #
# #
# Modules provide the P6Spy functionality. If a module, such #
# as module_log is commented out, that functionality will not #
# be available. If it is not commented out (if it is active), #
# the functionality will be active. #
# #
# Values set in Modules cannot be reloaded using the #
# reloadproperties variable. Once they are loaded, they remain #
# in memory until the application is restarted. #
# #
##############################################################
module.log=com.p6spy.engine.logging.P6LogFactory
#module.outage=com.p6spy.engine.outage.P6OutageFactory
#################################################################
# REALDRIVER(s) #
# #
# In your application server configuration file you replace the #
# "real driver" name with com.p6spy.engine.P6SpyDriver. This is #
# where you put the name of your real driver P6Spy can find and #
# register your real driver to do the database work. #
# #
# If your application uses several drivers specify them in #
# realdriver2, realdriver3. See the documentation for more #
# details. #
# #
# Values set in REALDRIVER(s) cannot be reloaded using the #
# reloadproperties variable. Once they are loaded, they remain #
# in memory until the application is restarted. #
# #

realdriver3=
#the DriverManager class sequentially tries every driver that is
#registered to find the right driver. In some instances, it's possible to
#load up the realdriver before the p6spy driver, in which case your connections
#will not get wrapped as the realdriver will "steal" the connection before
#p6spy sees it. Set the following property to "true" to cause p6spy to
#explicitily deregister the realdrivers

# P6LOG SPECIFIC PROPERTIES #
##############################################################
# no properties currently available
##############################################################
# 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. #
#
# executionthreshold=integer time (milliseconds)
#
executionthreshold=
##############################################################
# 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).
#
# outagedetection=true|false
# outagedetectioninterval=integer time (seconds)

# DataSource replacement #
# #
# Replace the real DataSource class in your application server #
# configuration with the name com.p6spy.engine.spy.P6DataSource,#
# then add the JNDI name and class name of the real #
# DataSource here #
# #
# Values set in this item cannot be reloaded using the #
# reloadproperties variable. Once it is loaded, it remains #
# in memory until the application is restarted. #
# #
##############################################################
#realdatasource=/RealMySqlDS
#realdatasourceclass=com.mysql.jdbc.jdbc2.optional.MysqlDataSource
##############################################################
# 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). #
# #
##############################################################
#jndicontextfactory=org.jnp.interfaces.NamingContextFactory
#jndicontextproviderurl=localhost:1099

3，修改Spring的context文件（本身引入了配置文件）：
