First add the following dependencies to the pom file

Org.apache.logging.log4j log4j-api 2.6.2 org.apache.logging.log4j log4j-core 2.6.2 org.apache.logging.log4j log4j-web 2.6.2 org.slf4j slf4j-api 1.7.12 org.slf4j jcl-over-slf4j 1.7.12 org.apache.logging.log4j log4j-slf4j-impl 2.6.2

Delete the original slf4j dependency

Org.slf4j slf4j-log4j12 1.7.7

Rewrite log4j.xml configuration file

The original log4j in the project prints logs on an hourly basis, so RollingRandomAccessFile is used.

Then, rename log4j.xml to log4j2.xml, and cancel the original context configuration in web.xml!

Because the above 1.1 did not do at the beginning, but only modified the content on the basis of the original log4j.xml, so when it was packaged and run on the server, there was no log file output, because other projects relied on in the pom file had log4j-related jar packages, and slf4j did not know which one to use.

Upgrade complete.
