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(); } }

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 

如果您正在使用hibernate 3.2。X使用这个:

log4j.logger.org.hibernate.SQL=trace

而不是这样:

log4j.logger.org.hibernate.SQL=debug

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]

正如我在这篇文章中所描述的，您可以使用数据源-代理来实现。

假设你的应用程序需要一个dataSource bean(例如通过@Resource)，你可以这样配置dataSource -proxy:

<bean id="actualDataSource" class="bitronix.tm.resource.jdbc.PoolingDataSource" init-method="init"
  destroy-method="close">
    <property name="className" value="bitronix.tm.resource.jdbc.lrc.LrcXADataSource"/>
    <property name="uniqueName" value="actualDataSource"/>
    <property name="minPoolSize" value="0"/>
    <property name="maxPoolSize" value="5"/>
    <property name="allowLocalTransactions" value="false" />
    <property name="driverProperties">
        <props>
            <prop key="user">${jdbc.username}</prop>
            <prop key="password">${jdbc.password}</prop>
            <prop key="url">${jdbc.url}</prop>
            <prop key="driverClassName">${jdbc.driverClassName}</prop>
        </props>
    </property>
</bean>

<bean id="proxyDataSource" class="net.ttddyy.dsproxy.support.ProxyDataSource">
    <property name="dataSource" ref="testDataSource"/>
    <property name="listener">
        <bean class="net.ttddyy.dsproxy.listener.ChainListener">
            <property name="listeners">
                <list>
                    <bean class="net.ttddyy.dsproxy.listener.CommonsQueryLoggingListener">
                        <property name="logLevel" value="INFO"/>
                    </bean>
                    <bean class="net.ttddyy.dsproxy.listener.DataSourceQueryCountListener"/>
                </list>
            </property>
        </bean>
    </property>
</bean>

<alias name="proxyDataSource" alias="dataSource"/>

现在Hibernate输出vs.数据源-代理:

INFO  [main]: n.t.d.l.CommonsQueryLoggingListener - Name:, Time:1, Num:1, Query:{[select company0_.id as id1_6_, company0_.name as name2_6_ from Company company0_][]}
INFO  [main]: n.t.d.l.CommonsQueryLoggingListener - Name:, Time:0, Num:1, Query:{[insert into WarehouseProductInfo (id, quantity) values (default, ?)][19]}
INFO  [main]: n.t.d.l.CommonsQueryLoggingListener - Name:, Time:0, Num:1, Query:{[insert into Product (id, code, company_id, importer_id, name, version) values (default, ?, ?, ?, ?, ?)][phoneCode,1,-5,Phone,0]}

数据源-代理查询包含参数值，您甚至可以添加自定义JDBC语句拦截器，以便从集成测试中捕获N+1个查询问题。
