您需要为以下类别启用日志记录:

SQL -设置为调试，以便在执行所有SQL DML语句时记录日志 type -设置为trace以记录所有JDBC参数

所以log4j配置可以是这样的:

# logs the SQL statements
log4j.logger.org.hibernate.SQL=debug 

# Logs the JDBC parameters passed to a query
log4j.logger.org.hibernate.type=trace 

第一种方法相当于冬眠。Show_sql =true遗留属性时，第二个函数将打印绑定的参数。

另一种解决方案(非基于hibernate)是使用像P6Spy这样的JDBC代理驱动程序。

解决方案是正确的，但也记录结果对象的所有绑定。为了防止这种情况，可以创建一个单独的追加器并启用过滤。例如:

<!-- A time/date based rolling appender -->
<appender name="FILE_HIBERNATE" class="org.jboss.logging.appender.DailyRollingFileAppender">
    <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
    <param name="File" value="${jboss.server.log.dir}/hiber.log"/>
    <param name="Append" value="false"/>
    <param name="Threshold" value="TRACE"/>
    <!-- Rollover at midnight each day -->
    <param name="DatePattern" value="'.'yyyy-MM-dd"/>

    <layout class="org.apache.log4j.PatternLayout">
        <!-- The default pattern: Date Priority [Category] Message\n -->
        <param name="ConversionPattern" value="%d %-5p [%c] %m%n"/>
    </layout>
  
    <filter class="org.apache.log4j.varia.StringMatchFilter">
        <param name="StringToMatch" value="bind" />
        <param name="AcceptOnMatch" value="true" />
    </filter>
    <filter class="org.apache.log4j.varia.StringMatchFilter">
        <param name="StringToMatch" value="select" />
        <param name="AcceptOnMatch" value="true" />
    </filter>  
    <filter class="org.apache.log4j.varia.DenyAllFilter"/>
</appender> 

<category name="org.hibernate.type">
  <priority value="TRACE"/>
</category>

<logger name="org.hibernate.type">
   <level value="TRACE"/> 
   <appender-ref ref="FILE_HIBERNATE"/>
</logger>

<logger name="org.hibernate.SQL">
   <level value="TRACE"/> 
   <appender-ref ref="FILE_HIBERNATE"/>
</logger>

对我来说，最简单的解决方案是实现一个常规的字符串替换，将参数输入替换为参数值(为了简单起见，将所有参数都视为字符串):

String debuggedSql = sql;
// then, for each named parameter
debuggedSql = debuggedSql.replaceAll(":"+key, "'"+value.toString()+"'");
// and finally
System.out.println(debuggedSql);

或者类似的位置参数(?)。

如果您想要记录运行就绪的SQL，请注意空值和特定的值类型(如date)。

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 )

Log4JDBC是一种很好的解决方案，它打印带有适当参数的精确SQL到数据库，而不是这里最流行的答案，它不这样做。这样做的一个主要便利之处在于，您可以直接将SQL复制到您的DB前端并原样执行它。

后者还输出查询结果的表格表示。

示例输出显示生成的SQL与参数一起到位的结果集表从查询:

5. insert into ENQUIRY_APPLICANT_DETAILS (ID, INCLUDED_IN_QUOTE, APPLICANT_ID, TERRITORY_ID, ENQUIRY_ID, ELIGIBLE_FOR_COVER) values (7, 1, 11, 1, 2, 0)

更新2016

最近我一直在使用log4jdbc-log4j2 (https://code.google.com/archive/p/log4jdbc-log4j2/)和SLF4j和logback。我的设置所需的Maven依赖项如下:

<dependency>
    <groupId>org.bgee.log4jdbc-log4j2</groupId>
    <artifactId>log4jdbc-log4j2-jdbc4.1</artifactId>
    <version>1.16</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>${slf4j.version}</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-core</artifactId>
    <version>${logback.version}</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>$logback.version}</version>
</dependency>

驱动程序和DB url如下所示:

database.driver.class=net.sf.log4jdbc.sql.jdbcapi.DriverSpy
database.url=jdbc:log4jdbc:hsqldb:mem:db_name #Hsql
#database.url=jdbc:log4jdbc:mysql://localhost:3306/db_name 

我的logback.xml配置文件如下所示:输出所有带有参数的SQL语句以及所有查询的结果集表。

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

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
            </pattern>
        </encoder>
    </appender>

    <logger name="jdbc.audit" level="ERROR" />
    <logger name="jdbc.connection" level="ERROR" />
    <logger name="jdbc.sqltiming" level="ERROR" />
    <logger name="jdbc.resultset" level="ERROR" />
    
    <!-- UNCOMMENT THE BELOW TO HIDE THE RESULT SET TABLE OUTPUT -->
    <!--<logger name="jdbc.resultsettable" level="ERROR" /> -->

    <root level="debug">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>

最后，我必须创建一个名为log4jdbc.log4j2的文件。例如，Maven项目中的src/test/resources或src/main/resources。这个文件只有一行:

log4jdbc.spylogdelegator.name=net.sf.log4jdbc.log.slf4j.Slf4jSpyLogDelegator

以上将取决于您的日志库。更多信息请参见https://code.google.com/archive/p/log4jdbc-log4j2上的文档。

样例输出:

10:44:29.400 [main] DEBUG jdbc.sqlonly -  org.hibernate.engine.jdbc.internal.ResultSetReturnImpl.extract(ResultSetReturnImpl.java:70)

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 ();
