Question

我有一个spring boot web应用程序。尝试自定义日志记录。我理解slf4j和log4j之间的区别。在这种情况下我需要使用log4j。在大多数情况下，它的工作方式如我所愿。

问题是，Hibernate正在向控制台打印SQL查询，并且基于我认为它根本不使用log4j的格式。我想进一步定制Hibernate的日志记录。我看到的大多数建议都假设Hibernate通过log4j进行日志记录。我如何让hibernate使用log4j作为其日志框架？

我尝试排除jboss日志记录，然后我了解到jboss实际上是一种类似于slf4j的外观，所以排除它似乎没有解决问题（当我特别咄咄逼人时，应用程序无法启动）< / p>

我还不知道jboss或hibernate是如何配置的。我是新手，所以如果您包含有关如何实施建议解决方案的详细说明，我将不胜感激。

更新有人问，是的，我正在使用Maven。我按照Spring Boot页面上的说明来排除logback，以便spring boot使用log4j。我现在确定大多数应用程序都使用log4j进行日志记录 - 直接或通过slf4j进行日志记录 - 因为系统正在按照我的log4j配置文件的指示进行操作。

应用程序是直接使用log4j还是slf4j，这是一个重要的难题，我将不得不检查。至于Hibernate正在做什么，我还不知道。当我执行我给出的建议时，我会提供进一步的更新。

非常感谢您的帮助和建议！

Answer 1

log4j是一个日志记录api，slf4j是在各种支持的日志记录apis之上的ab抽象

我怀疑在你的情况下你正在使用直接log4j并且hibernate日志记录是通过slf4j完成的，它与其他一些实现（除了log4j之外）绑定，尝试找出它被绑定到maven依赖树的日志记录< / p>

删除所有slf4j- *（slfj-api除外）并将其作为运行时依赖项slf4j-log4j，将slf4j调用绑定到log4j，它将引用放在classpath中的log4j.properties并尊重

Answer 2

您可以将slf4j与log4j一起使用。

你正在使用maven吗？如果是，您是否可以发布与slf4j或log4j相关的pom.xml依赖项？

另外，请查看以下链接：http://www.mkyong.com/hibernate/how-to-configure-log4j-in-hibernate-project/

对于log4j 1.2.x，以下maven依赖项将启动并运行slf4j appenders中的log4j日志消息：

    <!-- slf4j-log4j -->
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.6.1</version>
    </dependency>

对于log4j 2.x，以下maven依赖项将启动并运行slf4j appenders中的log4j日志消息：

<dependencies>
  <dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-slf4j-impl</artifactId>
    <version>2.2</version>
  </dependency>
</dependencies>

希望有所帮助！
