| <p>The Log4j 2 SLF4J Binding allows applications coded to the SLF4J API to use Log4j 2 as the implementation.</p> |
| <p>Due to a break in compatibility in the SLF4J binding, as of release 2.11.1 two SLF4J to Log4j Adapters are provided.</p> |
| |
| <ol style="list-style-type: decimal"> |
| |
| <li>log4j-slf4j-impl should be used with SLF4J 1.7.x releases or older.</li> |
| |
| <li>log4j-slf4j18-impl should be used with SLF4J 1.8.x releases or newer.</li> |
| </ol> |
| <p>Applications that take advantage of the Java Module System should use SLF4J 1.8.x and log4j-slf4j18-impl.</p> |
| <div class="section"> |
| <h2><a name="Requirements"></a>Requirements</h2> |
| <p>The Log4j 2 SLF4J Binding has a dependency on the Log4j 2 API as well as the SLF4J API. For more information, see <a href="../runtime-dependencies.html">Runtime Dependencies</a>.</p></div> |
| <div class="section"> |
| <h2><a name="Usage"></a>Usage</h2> |
| <p>The SLF4J binding provided in this component cause all the SLF4J APIs to be routed to Log4j 2. Simply include the Log4j 2 SLF4J Binding jar along with the Log4j 2 jars and SLF4J API jar to cause all SLF4J logging to be handled by Log4j 2.</p> |
| |
| <div class="alert alert-danger"> |
| Use of the Log4j 2 SLF4J Binding (log4j-slf4j-impl-2.0.jar) together with |
| the SLF4J adapter (log4j-to-slf4j-2.0.jar) should |
| never be attempted, as it will cause events to endlessly be routed between |
| SLF4J and Log4j 2. |
