Hi，大家好，我是编程小6，很荣幸遇见你，我把这些年在开发过程中遇到的问题或想法写出来，今天说一说
p6spy工具_p6软件安装教程,希望能够帮助你!!!。

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 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) # ################################################################# #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 ################################################################ # P6 LOGGING SPECIFIC PROPERTIES # ################################################################ # filter what is logged # please note this is a precondition for usage of: include/exclude/sqlexpression # (default is false) #filter=false # comma separated list of strings to include # please note that special characters escaping (used in java) has to be done for the provided regular expression # (default is empty) #include = # comma separated list of strings to exclude # (default is empty) #exclude = # sql expression to evaluate if using regex # please note that special characters escaping (used in java) has to be done for the provided regular expression # (default is empty) #sqlexpression = #list of categories to exclude: error, info, batch, debug, statement, #commit, rollback and result are valid values # (default is info,debug,result,resultset,batch) #excludecategories=info,debug,result,resultset,batch # Execution threshold 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.

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

##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
