前言：ssm框架集成的log4j打印的sql日志信息时，sql语句中总是出现？ 这种预编译sql的符号。而有时候sql过长，参数过多的情况下，查看完整sql以及拷贝sql入工具执行的情况下，比较麻烦。所以这里我使用集成p6spy打印完整sql方案解决这种问题。
1。准备p6spy的jar包
<dependency>
<groupId>p6spy</groupId>
<artifactId>p6spy</artifactId>
<version>3.0.0</version>
</dependency>2。在spring中配置数据源代理
<!-- p6spy sql dynamicDataSources:数据源或者是动态代理数据源-->
<bean id="dynamicDataSource" class="com.p6spy.engine.spy.P6DataSource">
<constructor-arg>
<ref bean="dynamicDataSources"/>
</constructor-arg>
</bean>3。新建一个spy.properties文件

#################################################################
# 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. #
# #
#################################################################
#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). #
# #
# (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

# 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. 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)
# (default is 0)
#executionThreshold=
################################################################
# P6 OUTAGE 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)
#
# (default is false)
#outagedetection=false
# (default is 60)
#outagedetectioninterval=304。然后在log4j里面加上p6spy的配置
##p6spy
log4j.logger.p6spy=info,spyConsole,spyFile
#配置p6spy的日志不重复打印
log4j.additivity.p6spy=false
#配置p6spy打印输出到控制台并定义其格式
log4j.appender.spyConsole = org.apache.log4j.ConsoleAppender
log4j.appender.spyConsole.Target=System.out
log4j.appender.spyConsole.layout = org.apache.log4j.PatternLayout
log4j.appender.spyConsole.layout.ConversionPattern = %m%n
#配置p6spy打印输出到文件并定义其格式
log4j.appender.spyFile = org.apache.log4j.RollingFileAppender
log4j.appender.spyFile.File = logs/spy/spy.log
log4j.appender.spyFile.MaxFileSize = 10MB
log4j.appender.spyFile.layout = org.apache.log4j.PatternLayout
log4j.appender.spyFile.layout.ConversionPattern = %m%n5。自定义p6spy格式化输出消息类
public class P6LpyLogger implements MessageFormattingStrategy {
private SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss:SSS");
public String formatMessage(int connectionId, String now, long elapsed, String category, String prepared, String sql) {
if (!sql.trim().equals("")) {
return "# " + format.format(new Date()) + " | took " + elapsed + "ms | " + category + " | connection " + connectionId + "\n "
+ sql + ";";
}
return "";
}
}
