Ubuntu

Sudo apt install libapr1 libapr1-dev libaprutil1 libtcnative-1

Add the parameter-Djava.library.path=/usr/lib/x86_64-linux-gnu when running jar, as follows:

Java-jar-Djava.library.path=/usr/lib/x86_64-linux-gnu.

Centos

There is no specific environment for testing, but the idea is the same: install apr and tomcat-native with yum, then run jar, and if you can't find it, add the-Djava.library.path parameter.

Alpine

Usually used in docker, the following code can be added to the Dockerfile file, and the runtime does not need to specify-Djava.library.path.

Apk add apr & apk add apr-util & & apk add apr-dev & & apk add tomcat-nativespring boot@Configurationpublic class APRConfig {@ Value ("${apr}") private boolean apr; @ Bean public TomcatServletWebServerFactory servletContainer () {TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory (); if (apr) {tomcat.setProtocol ("org.apache.coyote.http11.Http11AprProtocol"); tomcat.addContextLifecycleListeners (new AprLifecycleListener ()) } return tomcat;}} start
