使用此工具在运行代码需要访问数据库的时候,可以在控制台看见sql语句

在开发的过程中,我们经常会遇到由于sql语句书写错误导致的bug,那么如何来解决这种困扰呢?如果方法执行完了可以打印出完整的sql语句,就可以方便我们判断执行的是否正确,所以我们希望有一个可以打印sql语句的插件。p6spy就是一款这样的工具,下面给大家介绍一下p6spy的使用。

一、导包

# 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  #

# 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).                              #

# 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

三、修改database.properties中的driver和url

在这里插入图片描述

##mysql
#driver=com.mysql.jdbc.Driver
#url=jdbc:mysql://localhost:3306/db_test1?characterEncoding=utf-8
#username=root
#password=root
#p6spy
driver=com.p6spy.engine.spy.P6SpyDriver
url=jdbc:p6spy:mysql://localhost:3306/db_test1
username=root
password=root

接下来看我的运行结果
功能:先查找用户名是否存在,如果不存在就插入用户
