1、下载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.

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.

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) # outagedetection=false outagedetectioninterval= ################################################################ # COMMON PROPERTIES # ################################################################ # comma separated list of tables to include include = # comma separated list of tables to exclude exclude = # sql expression to evaluate if using regex sqlexpression = # filter what is logged filter=false # turn on tracing trace = true autoflush = true # sets the date format using Java's SimpleDateFormat routine dateformat= #list of categories to explicitly include includecategories= #list of categories to exclude: error, info, batch, debug, statement, #commit, rollback and result are valid values #excludecategories= excludecategories=info,debug,result,batch #allows you to use a regex engine or your own matching engine to determine #which statements to log # #stringmatcher=com.p6spy.engine.common.GnuRegexMatcher #stringmatcher=com.p6spy.engine.common.JakartaRegexMatcher stringmatcher= # prints a stack trace for every statement logged stacktrace=false # if stacktrace=true, specifies the stack trace to print stacktraceclass= # determines if property file should be reloaded reloadproperties=false # determines how often should be reloaded in seconds reloadpropertiesinterval=60 #if=true then url must be prefixed with p6spy: useprefix=false #specifies the appender to use for logging appender=com.p6spy.engine.logging.appender.Log4jLogger #appender=com.p6spy.engine.logging.appender.StdoutLogger #appender=com.p6spy.engine.logging.appender.FileLogger # name of logfile to use, note Windows users should make sure to use forward slashes in their pathname (e:/test/spy.log) (used for file logger only) #logfile = c:/spy.log # append to the p6spy log file. if this is set to false the # log file is truncated every time.

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 #jndicontextcustom=java.naming.factory.url.pkgs;org.jboss.nameing:org.jnp.interfaces #jndicontextfactory=com.ibm.websphere.naming.WsnInitialContextFactory #jndicontextproviderurl=iiop://localhost:900
3、修改hibernate的配置文件hibernate.cf.xml：
<!-- <property name="connection.driver_class">com.mysql.jdbc.Driver</property> -->
<property name="connection.driver_class">com.p6spy.engine.spy.P6SpyDriver</property>
<property name="connection.url">jdbc:mysql://localhost/hibernate</property>
<property name="connection.username">root</property>
<property name="connection.password">123456</property>
4、重新运行即可。
