Log SQL that is communicated with the database

Question

I am working on a SQL Logger for my web application. I want to be able to Log the SQL query that is fired by user-interaction with the GUI. I\'m working in a Spring environm

Answer 1

i use jdbcdslog-exp for cases like this.

add jdbcdslog-1.0.6.2.jar to classpath.

add categories to log4j configuration (set INFO for ResultSetLogger too if you want - beware of OutOfMemory)

<category name="org.jdbcdslog.StatementLogger">
  <priority value="INFO"/>
</category>  
<category name="org.jdbcdslog.ResultSetLogger">
  <priority value="FATAL"/>
</category>

if you need to switch statement logging by runtime you can start your log4j with

PropertyConfigurator.configureAndWatch("log4j.xml", 60000);

change your jdbc connection parameters (here example for hsql in jboss)

from

<connection-url>jdbc:hsqldb:hsql://localhost:1801</connection-url>
<driver-class>org.hsqldb.jdbcDriver</driver-class>

to

<connection-url>jdbc:jdbcdslog:hsqldb:hsql://localhost:1801;targetDriver=org.hsqldb.jdbcDriver</connection-url>
<driver-class>org.jdbcdslog.DriverLoggingProxy</driver-class>
