eclipse启动tomcat报错 Failed to initialize connector [Connector[org.apache.coyote.http11.Http11AprProtoc

tomcat版本是tomcat-8.5.42，在server.xml里面开启了APR模式，通过windows服务启动正常，但是通过eclipse启动tomcat出现下面的报错:The configured protocol [org.apache.coyote.http11.Http11AprProtocol] requires the APR/native library which is not available

解决办法：在tomcat的bin路径取中间的tcnative-1.dll文件，然后将该文件放入java.library.path的路径 C:\Program Files (x86)\Java\jre7\bin中。

#备注：如果当前tomcat版本没有tcnative-1.dll文件，下载与tomcat版本一致的tomcat-native-xxx-win32-bin.zip压缩包，并取中间的tcnative-1.dll文件。 提前一个地址 http://archive.apache.org/dist/tomcat/tomcat-connectors/native/
