display Hibernate SQL Per Console (primavera)

Question

Sto lavorando con molla 3, ibernazione 4. Sto cercando di seguire questo tutorial http://www.mkyong.com/hibernate/hibernate-display-generated-sql-to-console-show_sql-format_sql-and-use_sql_comments/, ma la mia configurazione hibernate è diverso:

<?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" 
    xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" 
    xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd 
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd 
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd 
    http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee.xsd"> 


    <!-- 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> 

E le proprietà show_sql , format_sql e use_sql_comments non funzionano in questo modo. Ricevo questa eccezione:

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? 

Esiste comunque il tutorial per la definizione del bean ??

Answer 1

show_sql non una proprietà di org.apache.commons.dbcp.BasicDataSource. Devi definirlo nella configurazione di fabbrica della sessione. come questo

<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> 

Answer 2

L'approccio più semplice è probabilmente quello di impostare seguente logger di DEBUG:

org.hibernate.SQL 

Se si utilizza log4j, trovare/creare un file log4j.properties sul radice classpath e aggiungere

log4j.logger.org.hibernate.SQL=DEBUG 

See qui per maggiori informazioni sulle proprietà di log4j: http://logging.apache.org/log4j/1.2/manual.html
