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?


当前回答

如果你正在使用Spring Boot,只需配置如下:

application.yml

logging:
  level:
    org.hibernate.SQL: DEBUG
    org.hibernate.type: TRACE

application.properties

logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type=TRACE

仅此而已。

你的日志会是这样的:

2020-12-07 | DEBUG | o.h.SQL:127 - insert into Employee (id, name, title, id) values (?, ?, ?, ?)
2020-12-07 | TRACE | o.h.t.d.s.BasicBinder:64 - binding parameter [1] as [VARCHAR] - [001]
2020-12-07 | TRACE | o.h.t.d.s.BasicBinder:64 - binding parameter [2] as [VARCHAR] - [John Smith]
2020-12-07 | TRACE | o.h.t.d.s.BasicBinder:52 - binding parameter [3] as [VARCHAR] - [null]
2020-12-07 | TRACE | o.h.t.d.s.BasicBinder:64 - binding parameter [4] as [BIGINT] - [1]

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>

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

打开org.hibernate.type记录器,查看实际参数是如何绑定到问号的。

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 )

如果你想让Hibernate用真实值而不是问号打印生成的SQL查询,请在Hibernate .cfg.xml/ Hibernate .properties中添加以下条目:

show_sql=true
format_sql=true
use_sql_comments=true

并在log4j.properties中添加以下条目:

log4j.logger.org.hibernate=INFO, hb
log4j.logger.org.hibernate.SQL=DEBUG
log4j.logger.org.hibernate.type=TRACE
log4j.appender.hb=org.apache.log4j.ConsoleAppender
log4j.appender.hb.layout=org.apache.log4j.PatternLayout
