Question

我正在尝试使用log4j将生成的SQL查询导出到控制台。使用Spring 4和Hibernate 4。

servlet-context.xml：

    <beans:bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <beans:property name="dataSource" ref="dataSource" />
    <beans:property name="configLocation" value="classpath:hibernate.cfg.xml" />
    <beans:property name="hibernateProperties">
        <beans:props>
            <beans:prop key="hibernate.show_sql">true</beans:prop>
        </beans:props>
    </beans:property>
</beans:bean>

hibernate.cfg.xml

<hibernate-configuration>
<session-factory>
    <property name="dialect">
        org.hibernate.dialect.MySQLDialect
    </property>
    <property name="show_sql">true</property>
    <property name="connection.autocommit">false</property>
</session-factory>

当我调用以下方法时，控制台不会生成任何信息：

List<Comment> listComment = (List<Comment>) sessionFactory.getCurrentSession()
            .createCriteria(Comment.class).list();

有什么建议吗？

我认为问题出在log4j.xml文件中。顺便说一句，我正在使用STS的Spring MVC项目。 Spring 4.3.2 + Hibernate 4.2.5 + Tomcat 8.0 + log4j 1.2.15。

的log4j.xml

<?xml version="1.0" encoding="UTF-8"?>

<!-- Appenders -->
<appender name="console" class="org.apache.log4j.ConsoleAppender">
    <param name="Target" value="System.out" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%-5p: %c - %m%n" />
    </layout>
</appender>

<!-- Application Loggers -->
<logger name="com.hersbitcloud.cancercloud">
    <level value="info" />
</logger>

<!-- 3rdparty Loggers -->
<logger name="org.springframework.core">
    <level value="info" />
</logger>

<logger name="org.springframework.beans">
    <level value="info" />
</logger>

<logger name="org.springframework.context">
    <level value="info" />
</logger>

<logger name="org.springframework.web">
    <level value="info" />
</logger>

<logger name="org.hibernate">
    <level value="info" />
</logger>

<logger name="org.hibernage.SQL">
    <level value="debug" />
</logger>

<!-- Root Logger -->
<root>
    <priority value="warn" />
    <appender-ref ref="console" />
</root>

Hibernate生成的日志是：

INFO : org.hibernate.annotations.common.Version - HCANN000001: Hibernate Commons Annotations {4.0.4.Final}
INFO : org.hibernate.Version - HHH000412: Hibernate Core {4.3.5.Final}

INFO : org.hibernate.hql.internal.ast.ASTQueryTranslatorFactory - HHH000397: Using ASTQueryTranslatorFactory
INFO : org.springframework.web.servlet.DispatcherServlet - FrameworkServlet 'appServlet': initialization completed in 2663 ms

甚至'sessionFactory.getCurrentSession（）。createCriteria'也不会生成任何SQL语句。

我应该在log4j.xml中添加什么内容吗？

Answer 1

I got everything to work by changing

<logger name="org.hibernate">
    <level value="info" />
</logger>

into

<logger name="org.hibernate">
    <level value="all" />
</logger>

Answer 2

根据我的知识，这可能是配置，

<session-factory>

   <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>

   <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/db</property>

   <property name="hibernate.connection.username">root</property>

    <property name="hibernate.connection.password">root</property>

   <property name="hibernate.show_sql">true</property>
