信息: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: C:\Program Files (x86)\Java\jdk1.8.0_73\bin;D:\AppData\Tomcat\apache-tomcat-7.0.53\bin

异常现象：正常使用中的Tomcat，在MyEclipse中切换了一下工作空间，出现如上异常，http://localhost:8080/首页打不开，用bin文件夹内的startup.bat打开报相同的异常。

解决过程：参考了网上很多解决办法，如查看JDK的位数是否和Tomcat运行系统的位数一致等等，均未解决！

解决办法：去Tomcat官网 重新下载相应的版本，并重新配置。
