显示Hibernate SQL到控制台(Spring)

我正在使用 spring 3,hibernate 4.我正在尝试按照本教程 http://www.mkyong.com/hibernate/hibernate-display-generated-sql-to-console-show_sql-format_sql-and-use_sql_comments/,但我的hibernate配置不同:

<?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>

并且属性show_sql,format_sql和use_sql_comments不能以这种方式工作.我得到这个例外:

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?

反正有没有用bean的定义来实现教程?

show_sql不是org.apache.commons.dbcp.BasicDataSource的属性.您必须在会话工厂配置中定义它.
像这样

<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>
