Display Hibernate SQL To Console (Spring) - sql

Question

I'm working with spring 3, hibernate 4. I'm trying to follow this tutorial http://www.mkyong.com/hibernate/hibernate-display-generated-sql-to-console-show_sql-format_sql-and-use_sql_comments/, but my hibernate configuration is different:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jee="http://www.springframework.org/schema/jee"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:beans="http://www.springframework.org/schema/beans"

<!-- JDBC Data Source. It is assumed you have MySQL running on localhost port 3306 with
username root and blank password. Change below if it's not the case -->
<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/project"/>
<property name="username" value="root"/>
<property name="password" value="1234"/>
<property name="validationQuery" value="SELECT 1"/>
<property name="show_sql" value="true" />
<property name="format_sql" value="true" />
<property name="use_sql_comments" value="true" />
</bean>
</beans>
And the properties show_sql, format_sql and use_sql_comments are not working this way. I get this exception:
Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'show_sql' of bean class [org.apache.commons.dbcp.BasicDataSource]: Bean property 'show_sql' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
Is there anyway to achieve the tutorial with the definition of the bean??

Answer 1

show_sql not a property of org.apache.commons.dbcp.BasicDataSource . You have to define it in session factory configuration.
like this
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="data" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.H2Dialect</prop>
<prop key="hibernate.current_session_context_class">thread</prop>
<prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
</bean>

The simplest approach probably is to set following logger to DEBUG:
org.hibernate.SQL
If you use log4j, find / create a log4j.properties file on your classpath root and add
log4j.logger.org.hibernate.SQL=DEBUG
See here for more info about log4j properties: http://logging.apache.org/log4j/1.2/manual.html

As I'm using JEE 8 and JBoss EAP, I managed to got the SQL after adding this line:
-Dorg.jboss.as.logging.per-deployment=false
on the end of "VM arguments" (Server tab -> JBoss Properties -> Open lauch configuration).
