IDEA启动tomcat时提示：...init The APR based Apache Tomcat Native library failed to load. The error reported was ...tcnative-1.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform

警告 [main] org.apache.catalina.core.AprLifecycleListener.init The APR based Apache Tomcat Native library failed to load. The error reported was [C:WindowsSystem32 cnative-1.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform] java.lang.UnsatisfiedLinkError: C:WindowsSystem32 cnative-1.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform at java.lang.ClassLoader$NativeLibrary.load(Native Method)

原因是tomcat可移植运行库在C:WindowsSystem32目录里缺少一个tcnative-1.dll文件；解决方法如下：

* 打开tomcat官网：http://tomcat.apache.org/

 

使用的是tomcat8.5，且报错信息提示的version是1.2，所以下载这个文件：

 

下载好后解压，打开bin文件夹，根据系统是32位还是64位，选择相应的tcnative-1.dll文件

 

 之后将该文件复制到 C:WindowsSystem32 下面即可，重启tomcat不再出现报错信息。
