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]

Log4Jdbc插件最适合您的需求。它显示如下-

1. Complete SQL query being hit to the db
2. Parameter values being passed to the query
3. Execution time taken by each query

参考下面的链接来配置Log4Jdbc-

https://code.google.com/p/log4jdbc/

在使用Wildfly (standalone.xml)进行开发时，添加以下记录器:

<logger category="org.hibernate.SQL">
   <level name="DEBUG"/>
</logger>
<logger category="org.hibernate.type.descriptor.sql">
   <level name="TRACE"/>
</logger>

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>

将hibernate.cfg.xml修改为:

<property name="show_sql">true</property>
<property name="format_sql">true</property>
<property name="use_sql_comments">true</property>

在"log4j.properties"中包含log4j和以下条目:

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
