警告: The APR based Apache Tomcat Native library failed to load.

（以下内容为自己在学习和开发中所遇到的问题及解决办法，如有不当之处，欢迎指正）

启动服务器，出现如下图所示警告，这是由于Tomcat服务器配置错误导致的。

解决方法：

以idea2019为例

1.Settings -> Build,Execution,Deployment -> Application Servers -> 移出之前部署的Tomcat

2.重新添加新的Tomcat

3.重新部署项目

我试了上面这种方法以后还是报错，又找了一种解决方法，这次成功了

1.打开cmd，在cmd中输入命令：java -version，按回车

2.查看内容是否包含“64”，如果不包含，说明你设置的【JAVA_HOME】的地址是指向32bit的jdk，那么你就需要下载一个64bit的jdk安装，并修改环境变量

电脑->属性->高级系统设置->高级->环境变量

3.安装配置完成以后，重新导入jdk，重启Tomcat运行，正常
