春季啓動Web應用程序：獲取休眠以使用log4j

Question

我有一個春季啓動Web應用程序。嘗試自定義日誌記錄。我瞭解slf4j和log4j之間的區別。在這種情況下我需要使用log4j。大多數情況下，它的工作方式是我想要的。

問題是，Hibernate將SQL查詢打印到控制檯，並基於格式，我認爲它根本不使用log4j。我想進一步定製Hibernate正在記錄的內容。我看到的大部分建議都假設Hibernate正在通過log4j進行日誌記錄。我怎麼會得到休眠使用log4j作爲其日誌框架？

我試着排除jboss日誌記錄，然後我知道jboss實際上是一個類似於slf4j的外觀排序，所以排除它似乎不能解決問題（並且當我對它有特別的侵略性時，應用程序無法啓動）

我還不知道如何配置jboss或hibernate。我對此很感興趣，所以如果您對如何實施建議的解決方案有合理的詳​​細說明，我將不勝感激。

更新： 有人問，是的，我使用的是Maven。 我遵循Spring Boot頁面的指導，以排除logback，以便spring引導改爲使用log4j。我確定現在絕大多數應用程序都使用log4j進行日誌記錄 - 無論是直接還是通過slf4j - 因爲系統正在按照我的log4j配置文件指示進行操作。

無論應用程序是直接使用log4j還是slf4j，都是難題中的重要部分，這是我必須檢查的。至於Hibernate在做什麼，我還不知道。我會提供進一步的更新，因爲我執行了我提出的建議。

非常感謝您的幫助和建議！

Answer 1

log4j的是一個日誌API，SLF4J是各種支持的日誌記錄API

我在你的情況下懷疑的頂部AB抽象您正在使用直的log4j並通過slf4j完成休眠日誌記錄，該日誌與其他實現綁定（log4j除外），嘗試找出綁定到或從您的Maven依賴關係樹中記錄的日誌記錄

刪除所有slf4j- *（除了slfj- api）和plac e作爲運行時依賴項slf4j-log4j，它將把slf4j調用綁定到log4j，它將引用放置在classpath中的log4j.properties，並尊重那個

Answer 2

您可以使用slf4j和log4j。

您使用的是maven嗎？如果是這樣，你可以發佈與slf4j或log4j相關的pom.xml依賴關係嗎？

此外，檢查出此鏈接：http://www.mkyong.com/hibernate/how-to-configure-log4j-in-hibernate-project/

對於log4j 1.2.x，以下Maven依賴將讓你和你的log4j追加程序與slf4j日誌消息運行：

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

對於log4j 2.x中，以下maven dependency會讓你啓動並運行你的日誌消息在你的log4j appender：

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

希望有幫助！
