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?

如果您正在使用hibernate 3.2。X使用这个:
log4j.logger.org.hibernate.SQL=trace
而不是这样:
log4j.logger.org.hibernate.SQL=debug

MySQL JDBC驱动程序已经提供了一个方便的特性来满足这个需求。您必须至少拥有大于或等于5.1.6的JAR版本(例如mysql-connect-jar-5.1.6.jar)。
配置jdbc。添加日志记录器和自定义日志记录器的Url: jdbc.url = jdbc: mysql: / /主持人:港口/ your_db ?记录器= com.mysql.jdbc.log.Slf4JLogger&profileSQL = true&profilerEventHandler = com.xxx.CustomLoggingProfilerEventHandler
它使用slf4j日志记录,如果你的默认日志记录是log4j,你必须添加slf4j-api和slf4j-log4j12作为依赖项来使用slf4j日志记录:
Write your custom logging code: package com.xxx; import java.sql.SQLException; import java.util.Properties; import com.mysql.jdbc.Connection; import com.mysql.jdbc.log.Log; public class CustomLoggingProfilerEventHandler implements ProfilerEventHandler { private Log log; public LoggingProfilerEventHandler() { } public void consumeEvent(ProfilerEvent evt) { /** * you can only print the sql as his.log.logInfo(evt.getMessage()) * you can adjust your sql print log level with: DEBUG,INFO * you can also handle the message to meet your requirement */ this.log.logInfo(evt); } public void destroy() { this.log = null; } public void init(Connection conn, Properties props) throws SQLException { this.log = conn.getLog(); } }
如果您使用Spring Boot 3和/或Hibernate 6,以下配置将显示参数值:
# basic log level for all messages
logging.level.org.hibernate=info
# SQL statements and parameters
logging.level.org.hibernate.SQL=debug
logging.level.org.hibernate.orm.jdbc.bind=trace
# Statistics and slow queries
logging.level.org.hibernate.stat=debug
logging.level.org.hibernate.SQL_SLOW=info
# 2nd Level Cache
logging.level.org.hibernate.cache=debug
你可以记录这个:net.sf.hibernate.hql.QueryTranslator
输出的例子:
2013-10-31 14:56:19,029 DEBUG [net.sf.hibernate.hql.QueryTranslator] HQL: select noti.id, noti.idmicrosite, noti.fcaducidad, noti.fpublicacion, noti.tipo, noti.imagen, noti.visible, trad.titulo, trad.subtitulo, trad.laurl, trad.urlnom, trad.fuente, trad.texto from org.ibit.rol.sac.micromodel.Noticia noti join noti.traducciones trad where index(trad)='ca' and noti.visible='S' and noti.idmicrosite=985 and noti.tipo=3446
2013-10-31 14:56:19,029 DEBUG [net.sf.hibernate.hql.QueryTranslator] SQL: select noticia0_.NOT_CODI as x0_0_, noticia0_.NOT_MICCOD as x1_0_, noticia0_.NOT_CADUCA as x2_0_, noticia0_.NOT_PUBLIC as x3_0_, noticia0_.NOT_TIPO as x4_0_, noticia0_.NOT_IMAGEN as x5_0_, noticia0_.NOT_VISIB as x6_0_, traduccion1_.NID_TITULO as x7_0_, traduccion1_.NID_SUBTIT as x8_0_, traduccion1_.NID_URL as x9_0_, traduccion1_.NID_URLNOM as x10_0_, traduccion1_.NID_FUENTE as x11_0_, traduccion1_.NID_TEXTO as x12_0_ from GUS_NOTICS noticia0_ inner join GUS_NOTIDI traduccion1_ on noticia0_.NOT_CODI=traduccion1_.NID_NOTCOD where (traduccion1_.NID_CODIDI='ca' )and(noticia0_.NOT_VISIB='S' )and(noticia0_.NOT_MICCOD=985 )and(noticia0_.NOT_TIPO=3446 )

log4j.logger.org.hibernate.SQL=trace
而不是这样:
log4j.logger.org.hibernate.SQL=debug
日志可以工作,但并不是您想要的,但P6Spy可以完美地工作。
这里有一个简单的教程来实现以及。对我来说,这就像魅力。
下载P6Spy库:获取P6Spy -install.jar 解压:解压p6spy-install.jar文件,查找p6spy.jar和spy.properties 添加库依赖项:将p6spy.jar添加到项目库依赖项中 Modify P6Spy properties file:修改数据库配置文件。您需要用P6Spy JDBC驱动程序替换现有的JDBC驱动程序。
原来是MySQL JDBC驱动程序- (com.mysql.jdbc.Driver)
<session-factory>
<property name="hibernate.bytecode.use_reflection_optimizer">false</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <!-- note the difference -->
<property name="hibernate.connection.password">password</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/myuser</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="show_sql">true</property>
</session-factory>
更改为P6Spy JDBC驱动程序(com.p6spy.engine.spy.P6SpyDriver)
<session-factory>
<property name="hibernate.bytecode.use_reflection_optimizer">false</property>
<property name="hibernate.connection.driver_class">com.p6spy.engine.spy.P6SpyDriver</property> <!-- note the difference -->
<property name="hibernate.connection.password">password</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/myuser</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="show_sql">true</property>
</session-factory>
修改P6Spy属性文件:spy.properties
用现有的MySQL JDBC驱动程序替换realdriver
realdriver=com.mysql.jdbc.Driver
# specifies another driver to use
realdriver2=
# specifies a third driver to use
realdriver3=
在logfile属性中更改日志文件的位置。所有SQL语句都将被记录到这个文件中。
窗口:
logfile=c:/spy.log
UNIX:
logfile=/srv/log/spy.log
复制的间谍。属性到项目类路径:复制间谍。属性添加到项目根文件夹。确保你的项目可以定位间谍。财产,否则就是间谍。属性文件未找到异常将被抛出。
