普通情况下,控制台打印出的sql是带?的,开发人员在自己调试的过程中遇到bug是再常见不过了,如果想看一下程序打出来的sql,发现参数的位置都是?,是不是很不爽,若想在数据库中执行sql,还需要手动修改sql的参数,真是麻烦,使用p6spy可以将sql格式化然后打出,打出的sql不再是带有?的,而是可以直接拷贝到数据库执行的。整合步骤如下:

# <table>   <tbody>    <tr>     <td><font>添加jar包依赖</font></td>    </tr>   </tbody>  </table> #

在service层添加依赖: \`\`\` p6spy p6spy 3.7.0

# DataSource replacement #

#  #

# Replace the real DataSource class in your application server #

# configuration with the name com.p6spy.engine.spy.P6DataSource #

# (that provides also connection pooling and xa support). #

# 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. #

# 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 #

# 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). #

#  #

# (by default all these are empty) #

# 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) #

#  #

# (default is false) #

\#outagedetection=false

# (default is 60) #

\#outagedetectioninterval=30
