问题：tomcat容器启动时报错：

The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found

原因：tomcat的系统环境变量没有配置。

解决办法：

配置Tomcat环境变量

1，新建变量名：CATALINA_HOME，变量值（tomcat的解压包路径或者安装路径）如：C:\tomcat

2，打开PATH，添加变量值：%CATALINA_HOME%\lib;%CATALINA_HOME%\bin

3，重启eclipse即可。重启eclipse才能使新配置的环境变量生效。
