tomcat8/9集成log4j2

蜀川居 2019-01-24

1、下载tomcat8.0.53 中的插件tomcat-juli.jar和tomcat-juli-adapters.jar两个jar把,经过测试,这两个jar适用于tomcat8.0、8.5、9.0
2、下载log4j-1.2-api-2.11.1.jar、log4j-api-2.11.1.jar、log4j-core-2.11.1.jar三个jar包,此处注意log4j2有bug,
笔者第一次使用2.8.2三个jar包,启动tomcat后写入文件的日志正常,但是控制台输出一直报错,错误内容如下:

 经在百度查找发现是log4j2的bug,该bug在2.8.2以后修改,提示升级到最新版的log4j2,因此笔者升级到2.11.1后就正常了。
3、将这5个jar拷贝到tomcat/lib目录下
4、将tomcat-juli.jar覆盖到tomcat/bin目录下
5、删除tomcat/conf下logging.properties文件
6、在tomcat/lib目录下创建log4j.xml文件,内容如下:
