最近在学习 JavaWeb 需要要用到服务器，果断安装 Tomcat，安装完成后发现在 IntelliJ Idea 中启动时老是会出现如下警告:The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path:…查阅和参考了一大坨资料后总结一下解决方法。
1. 下载并编译 APR
下载 APR
在终端编译 APR
1
cd /<your_apr_dir>/aprCFLAGS='-arch x86_64' ./configuremakesudo make install
2. 下载并编译 APR-util
下载 APR-util
在终端编译 APR-util
1
cd /<your_apr-util_dir>/apr-utilCFLAGS='-arch x86_64' ./configure --with-apr=/usr/local/apr/bin/apr-1-configmakesudo make install
3. 安装 OpenSSL
安装 OpenSSL 之前首先需要在 Homebrew 安装 Homebrew.
安装完成后打开终端输入下面命令
编译 Tomcat native 库
Tomcat native 库已经提供在下载好的 Tomcat 中了. 我下载的 Tomcat 版本是 apache-tomcat-8.5.27, 其中 jdk 的路径需要自行更换
1
cd /<your_tomcat_dir>/bingunzip tomcat-native.tar.gztar xf tomcat-native.tarcd /<your_tomcat-native_dir>/nativeCFLAGS='-arch x86_64' ./configure --with-apr=/usr/local/apr --with-ssl=/usr/local/opt/openssl --with-java-home=/Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Homemakesudo make install
配置 Tomcat 关联路径
1
sudo ln -s /usr/local/apr/lib/libtcnative-1.dylib /Library/Java/Extensions/
在 IntelliJ idea 中启动 Tomcat，如果看到下面的提示则证明 APR 安装成功.
