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]

使用Wireshark或类似的工具:

上面提到的答案都不会正确地打印带参数的SQL，或者让它与它们一起工作是一件痛苦的事情。我通过使用WireShark实现了这一点，它可以捕获从应用程序发送到Oracle/MySQL等的所有SQL/命令。

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

<!-- A time/date based rolling appender -->
<appender name="FILE" class="org.apache.log4j.RollingFileAppender">

</appender>

    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%d %d{Z} [%t] %-5p (%F:%L) - %m%n" />
    </layout>
</appender>

<logger name="com.journaldev.hibernate" additivity="false">
    <level value="DEBUG" />
    <appender-ref ref="journaldev-hibernate" />

<logger name="org.hibernate" additivity="false">

    <appender-ref ref="FILE" />

使用YAML属性:

logging.level.org.hibernate:
    SQL: DEBUG
    type.descriptor.sql.BasicBinder: TRACE
