在Hibernate中是否有可能用真实值而不是问号打印生成的SQL查询?
如果无法使用Hibernate API,您会建议如何使用实际值打印查询?

将以下内容添加到log4j或logback配置中:
org.hibernate.sql=DEBUG
org.hibernate.type.descriptor.sql.BasicBinder=TRACE
其他回答
您可以在log4j.xml中添加类别行:
<category name="org.hibernate.type">
<priority value="TRACE"/>
</category>
并添加hibernate属性:
<property name="show_sql">true</property>
<property name="format_sql">true</property>
<property name="use_sql_comments">true</property>
正如我在这篇文章中所描述的,您可以使用数据源-代理来实现。
假设你的应用程序需要一个dataSource bean(例如通过@Resource),你可以这样配置dataSource -proxy:
<bean id="actualDataSource" class="bitronix.tm.resource.jdbc.PoolingDataSource" init-method="init"
destroy-method="close">
<property name="className" value="bitronix.tm.resource.jdbc.lrc.LrcXADataSource"/>
<property name="uniqueName" value="actualDataSource"/>
<property name="minPoolSize" value="0"/>
<property name="maxPoolSize" value="5"/>
<property name="allowLocalTransactions" value="false" />
<property name="driverProperties">
<props>
<prop key="user">${jdbc.username}</prop>
<prop key="password">${jdbc.password}</prop>
<prop key="url">${jdbc.url}</prop>
<prop key="driverClassName">${jdbc.driverClassName}</prop>
</props>
</property>
</bean>
<bean id="proxyDataSource" class="net.ttddyy.dsproxy.support.ProxyDataSource">
<property name="dataSource" ref="testDataSource"/>
<property name="listener">
<bean class="net.ttddyy.dsproxy.listener.ChainListener">
<property name="listeners">
<list>
<bean class="net.ttddyy.dsproxy.listener.CommonsQueryLoggingListener">
<property name="logLevel" value="INFO"/>
</bean>
<bean class="net.ttddyy.dsproxy.listener.DataSourceQueryCountListener"/>
</list>
</property>
</bean>
</property>
</bean>
<alias name="proxyDataSource" alias="dataSource"/>
现在Hibernate输出vs.数据源-代理:
INFO [main]: n.t.d.l.CommonsQueryLoggingListener - Name:, Time:1, Num:1, Query:{[select company0_.id as id1_6_, company0_.name as name2_6_ from Company company0_][]}
INFO [main]: n.t.d.l.CommonsQueryLoggingListener - Name:, Time:0, Num:1, Query:{[insert into WarehouseProductInfo (id, quantity) values (default, ?)][19]}
INFO [main]: n.t.d.l.CommonsQueryLoggingListener - Name:, Time:0, Num:1, Query:{[insert into Product (id, code, company_id, importer_id, name, version) values (default, ?, ?, ?, ?, ?)][phoneCode,1,-5,Phone,0]}
数据源-代理查询包含参数值,您甚至可以添加自定义JDBC语句拦截器,以便从集成测试中捕获N+1个查询问题。
在Java中:
如果查询是CriteriaQuery (javax.persistence),则转换TypedQuery中的查询。
然后:
query.unwrap (org.hibernate.Query.class) .getQueryString ();

您需要配置如下:
# Hibernate logging options (INFO only shows startup messages)
log4j.logger.org.hibernate=INFO
# Log JDBC bind parameter runtime arguments
log4j.logger.org.hibernate.type=trace
