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?

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。
为了方便起见，下面是Logback (SLF4J)的相同配置示例
<appender name="SQLROLLINGFILE">
<File>/tmp/sql.log</File>
<rollingPolicy>
<FileNamePattern>logFile.%d{yyyy-MM-dd}.log</FileNamePattern>
</rollingPolicy>
<layout>
<Pattern>%-4date | %msg %n</Pattern>
</layout>
</appender>
<logger name="org.hibernate.SQL" additivity="false" >
<level value="DEBUG" />
<appender-ref ref="SQLROLLINGFILE" />
</logger>
<logger name="org.hibernate.type" additivity="false" >
<level value="TRACE" />
<appender-ref ref="SQLROLLINGFILE" />
</logger>
sql.log(示例)中的输出如下所示:

我喜欢log4j:
log4j.logger.org.hibernate.SQL=trace
log4j.logger.org.hibernate.engine.query=trace
log4j.logger.org.hibernate.type=trace
log4j.logger.org.hibernate.jdbc=trace
log4j.logger.org.hibernate.type.descriptor.sql.BasicExtractor=error
log4j.logger.org.hibernate.type.CollectionType=error
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。
http://log4jdbc.sourceforge.net/ https://code.google.com/p/log4jdbc-remix/
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)

10 Oct 2013 16:21:22 4953 [main] INFO jdbc.resultsettable - |---|--------|--------|-----------|----------|---------|-------|
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。

Hibernate在不同的行中显示查询及其参数值。
如果你正在使用应用程序。你可以在application.properties中使用下面突出显示的参数。
org.hibernate.SQL will show queries: logging.level.org.hibernate.SQL=DEBUG org.hibernate.type will show all parameter values, which will map with select, insert and update queries. logging.level.org.hibernate.type=TRACE org.hibernate.type.EnumType will show enum type parameter value: logging.level.org.hibernate.type.EnumType=TRACE Example output: 2018-06-14 11:06:28,217 TRACE [main] [EnumType.java : 321] Binding [active] to parameter: [1] sql.BasicBinder will show integer, varchar, boolean type parameter value logging.level.org.hibernate.type.descriptor.sql.BasicBinder=TRACE Example output: * 2018-06-14 11:28:29,750 TRACE [http-nio-9891-exec-2] [BasicBinder.java : 65] binding parameter [1] as [BOOLEAN] - [true] * 2018-06-14 11:28:29,751 TRACE [http-nio-9891-exec-2] [BasicBinder.java : 65] binding parameter [2] as [INTEGER] - [1] * 2018-06-14 11:28:29,752 TRACE [http-nio-9891-exec-2] [BasicBinder.java : 65] binding parameter [3] as [VARCHAR] - [public]
