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/

MySQL JDBC驱动程序已经提供了一个方便的特性来满足这个需求。您必须至少拥有大于或等于5.1.6的JAR版本(例如mysql-connect-jar-5.1.6.jar)。

配置jdbc。添加日志记录器和自定义日志记录器的Url: jdbc.url = jdbc: mysql: / /主持人:港口/ your_db ?记录器= com.mysql.jdbc.log.Slf4JLogger&profileSQL = true&profilerEventHandler = com.xxx.CustomLoggingProfilerEventHandler

它使用slf4j日志记录，如果你的默认日志记录是log4j，你必须添加slf4j-api和slf4j-log4j12作为依赖项来使用slf4j日志记录:

Write your custom logging code: package com.xxx; import java.sql.SQLException; import java.util.Properties; import com.mysql.jdbc.Connection; import com.mysql.jdbc.log.Log; public class CustomLoggingProfilerEventHandler implements ProfilerEventHandler { private Log log; public LoggingProfilerEventHandler() { } public void consumeEvent(ProfilerEvent evt) { /** * you can only print the sql as his.log.logInfo(evt.getMessage()) * you can adjust your sql print log level with: DEBUG,INFO * you can also handle the message to meet your requirement */ this.log.logInfo(evt); } public void destroy() { this.log = null; } public void init(Connection conn, Properties props) throws SQLException { this.log = conn.getLog(); } }

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]

将以下内容添加到log4j或logback配置中:

org.hibernate.sql=DEBUG
org.hibernate.type.descriptor.sql.BasicBinder=TRACE

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
