使用 logback 和 slf4j 记录休眠参数值

Question

我使用hibernate、spring mvc 和eclipse。在我的eclipse控制台中，hibernate sql以如下形式显示：

Hibernate: insert into some_table (fieldname1, fieldname2, fieldname3, fieldname4)  
values (?, ?, ?, ?)

如何让控制台打印出插入到问号位置的值？我致力于使用 slf4j 和 logback 来登录我的应用程序。

这是我的 logback.xml：

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="30 seconds">

    <contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator">
        <resetJUL>true</resetJUL>
    </contextListener>

    <!-- To enable JMX Management -->
    <jmxConfigurator/>

    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%-5level %logger{0} - %msg%n</pattern>
        </encoder>
    </appender>

    <!--<logger name="org.hibernate" level="debug"/> -->
    <logger name="mypackagename.myappname" level="debug"/>
    <logger name="org.hibernate.SQL" additivity="false" level="DEBUG" />
    <logger name="org.hibernate.type" additivity="false" level="TRACE" />

    <root level="info">
        <appender-ref ref="console"/>
    </root>
</configuration>

Answer 1

正确的工作答案原来是：

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="30 seconds">

    <contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator">
        <resetJUL>true</resetJUL>
    </contextListener>

    <!-- To enable JMX Management -->
    <jmxConfigurator/>

    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%-5level %logger{0} - %msg%n</pattern>
        </encoder>
    </appender>

    <logger name="mypackagename.myappname" level="TRACE"/>
    <logger name="org.hibernate.SQL" level="DEBUG" />
    <logger name="org.hibernate.type" level="TRACE" />

    <root level="info">
        <appender-ref ref="console"/>
    </root>
</configuration>

Answer 2

配置org.hibernate.type.descriptor.sql.BasicBinder包记录TRACE级别：

 <logger name="org.hibernate.type.descriptor.sql.BasicBinder" additivity="false" level="TRACE" />

Answer 3

这是关于所提供的 2 个答案的一些信息。两者都为我工作。

用于打印您想要的查询：

<logger name="org.hibernate.SQL" additivity="false" >
    <level value="DEBUG" />
    <appender-ref ref="SQLROLLINGFILE" />
    <appender-ref ref="STDOUT" />
</logger>

要“漂亮”地打印它，您可以使用jpaProperties.put("hibernate.format_sql", true|false); 更多信息在 [https://docs.jboss.org/hibernate/stable/core.old/reference/en/html/configuration-optional.html]

现在关于价值观。 接受：

<logger name="org.hibernate.type" additivity="false" >
    <level value="TRACE" />
    <appender-ref ref="SQLROLLINGFILE" />
    <appender-ref ref="STDOUT" />
</logger>

输出将是：

2017-02-12 14:16:57 DEBUG org.hibernate.SQL - 
    select
        producttyp0_.idProductType as idProduc1_25_1_,
        producttyp0_.deleted as deleted2_25_1_,

    from
        ProductType producttyp0_ 
    left outer join
        Product products1_ 
            on producttyp0_.idProductType=products1_.idProductType 
    where
        producttyp0_.idProductType=?

以及其他提供的解决方案

<logger name="org.hibernate.type.descriptor.sql.BasicBinder" additivity="false" level="TRACE" >
    <level value="TRACE" />
    <appender-ref ref="SQLROLLINGFILE" />
    <appender-ref ref="STDOUT" />
</logger>

输出将是：

2017-02-12 14:18:55 DEBUG org.hibernate.SQL - 
    select
        producttyp0_.idProductType as idProduc1_25_1_,

        producttyp0_.name as name4_25_1_,
        products1_.idProductType as idProduc6_25_3_,
        products1_.idProduct as idProduc1_24_3_,
        products1_.idProduct as idProduc1_24_0_,
        products1_.deleted as deleted2_24_0_,
        products1_.maxQty as maxQty3_24_0_,
        products1_.name as name4_24_0_,
        products1_.price as price5_24_0_,
        products1_.idProductType as idProduc6_24_0_ 
    from
        ProductType producttyp0_ 
    left outer join
        Product products1_ 
            on producttyp0_.idProductType=products1_.idProductType 
    where
        producttyp0_.idProductType=?
2017-02-12 14:18:55 TRACE o.h.type.descriptor.sql.BasicBinder - binding parameter [1] as [INTEGER] - [36]

我个人喜欢第二个，因为信息较少（避免使用 o.h.t.descriptor.sql.BasicExtractor），但这取决于项目。

希望它能提供更多关于包含哪些内容的信息。
