问题描述
是否可以对 java.util.logging.Logger 进行典型调用，并使用SLF4J将其路由到Logback？这将是很好的，因为我不必逐行重构旧的jul代码。
Is it possible to have a typical call to java.util.logging.Logger and have it route to Logback using SLF4J? This would be nice since I wouldn't have to refactor the old jul code line by line.
EG，我们有这条线：
EG, say we have this line:
private static Logger logger = Logger.getLogger(MahClass.class.getName());
//...
logger.info("blah blah blah");
将其配置为通过SLF4J调用会很好。
It would be nice to configure this to call through SLF4J.
推荐答案
这很容易而且不再是性能问题了。
It's very easy and not a performance issue anymore.
。 中也有精确的例子
There are two ways documented in the SLF4J manual. There are also precise examples in the Javadocs
将jul-to-slf4j.jar添加到类路径中。或者通过maven依赖：
Add jul-to-slf4j.jar to your classpath. Or through maven dependency:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jul-to-slf4j</artifactId>
<version>1.7.0</version>
</dependency>
如果你没有logging.properties（对于java.util.logging），请将此添加到你的引导代码：
If you don't have logging.properties (for java.util.logging), add this to your bootstrap code:
SLF4JBridgeHandler.removeHandlersForRootLogger();
SLF4JBridgeHandler.install();
如果你有logging.properties（并希望保留它），请将其添加到它：
If you have logging.properties (and want to keep it), add this to it:
handlers = org.slf4j.bridge.SLF4JBridgeHandler
为了避免性能损失，请将此contextListener添加到logback.xml（从logback版本0.9.25开始）：
In order to avoid performance penalty, add this contextListener to logback.xml (as of logback version 0.9.25):
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator">
<!-- reset all previous level configurations of all j.u.l. loggers -->
<resetJUL>true</resetJUL>
</contextListener>
...
</configuration>
