集成p6spy到spring中

网上好多帖子都是说，修改原有 JDBC Driver为：com.p6spy.engine.spy.P6SpyDriver

然后修改spy.properties 中的 realdriver值为原有的JDBC Driver

如果在spring开发环境中使用org.springframework.jdbc.datasource.DriverManagerDataSource来模拟dataSource是不会生效的，

Java代码  

1. <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
2. <property  name="driverClassName">
3. <value>com.sybase.jdbc2.jdbc.SybDriver</value>
4. </property>
5. <property  name="url">
6. <value>jdbc:sybase:Tds:192.168.0.2:6100/db</value>
7. </property>
8. <property  name="username">
9. <value>usr</value>
10. </property>
11. <property  name="password">
12. <value>pwd</value>
13. </property>
14. </bean>

因为在spring加载时我们无法控制先加载哪个，spring会报错不能使用com.p6spy.engine.spy.P6SpyDriver连接到数据库，

其实p6spy只是想做jdbc的代理，而不是真正想连数据库，而spring却不知道这些，所以应该采用另外一种方式来集成p6spy

Java代码  

1. <bean id="dataSourceTarget" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
2. <property  name="driverClassName">
3. <value>com.sybase.jdbc2.jdbc.SybDriver</value>
4. </property>
5. <property  name="url">
6. <value>jdbc:sybase:Tds:192.168.0.2:6100/db</value>
7. </property>
8. <property  name="username">
9. <value>usr</value>
10. </property>
11. <property  name="password">
12. <value>pwd</value>
13. </property>
14. </bean>
15. <bean id="dataSource" class="com.p6spy.engine.spy.P6DataSource"
16. destroy-method="close">
17. <constructor-arg>
18. <ref local="dataSourceTarget"/>
19. </constructor-arg>
20. </bean>

有时候会报错cvc-complex-type.3.2.2: 元素 ‘ref‘ 中不允许出现属性 ‘local‘，

只需要把local改成bean就可以了。估计新版本去掉了这个local

这样就可以把p6spy集成到spring中去了。

配置文件spy.properties

################################################################
# EXECUTION THRESHOLD PROPERTIES #
################################################################
# This feature 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. #

# 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).

# DataSource properties #
# #
# If you are using the DataSource support to intercept calls #
# to a DataSource that requires properties for proper setup, #

# pairs with commas. #
# #

# 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). #
