受Leif的Hypoport帖子启发,这就是我将Hibernate 4弯曲到slf4j的方式:
假设您正在使用Maven。
- 添加
org.slf4j:log4j-over-slf4j
为对您的依赖pom.xml
- 使用命令
mvn dependency:tree
,确保没有你使用上depende的文物slf4j:slf4j
(准确地说,没有神器应有编译范围依赖或运行时对范围的依赖性slf4j:slf4j
)
背景:Hibernate 4.x依赖于工件org.jboss.logging:jboss-logging
。及物,这件神器有一个提供对神器范围的依赖性slf4j:slf4j
。
当我们现在添加了org.slf4j:log4j-over-slf4j
工件时,org.slf4j:log4j-over-slf4j
模仿该slf4j:slf4j
工件。因此,所有JBoss Logging
记录的日志现在实际上都将通过slf4j传递。
假设您使用Logback作为日志记录后端。这是一个样本pom.xml

在您的类路径上,有个logback.xml
,例如位于的src/main/java
:
<!-- begin: logback.xml -->
<configuration>
<appender name="console" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<logger name="org.hibernate" level="debug"/>
<root level="info">
<appender-ref ref="console"/>
</root>
</configuration>
<!-- end: logback.xml -->
一些组件可能想要logback.xml
在JVM启动时访问以进行正确的日志记录,例如Jetty Maven插件。在这种情况下,请将Java系统添加logback.configurationFile=./path/to/logback.xml
到您的命令中(例如mvn -Dlogback.configurationFile=./target/classes/logback.xml jetty:run
)。
如果您仍在获取“原始”控制台标准输出的Hibernate输出(如Hibernate: select ...
),则可能适用堆栈溢出问题“ 关闭向控制台的休眠记录 ”。
