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(); } }

使用YAML属性:

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

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:

打开org.hibernate.type记录器，查看实际参数是如何绑定到问号的。

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。
