原因：

　　这个问题是说 tomcat 不能在 64 位平台上加载 32 的 tomcat。

　　也就是说 tomcat 的版本和我电脑里 jdk 的版本不一致。查一下我的电脑 jdk 版本为 64 位系统。

解决：启动项目报错 java.lang.UnsatisfiedLinkError: D:\Java\apache-tomcat-8.0.17\bin\tcnative-1.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform

解决办法：

　　将 tomcat 换为 64 的。在官网上下载 http://tomcat.apache.org/ 。

　　换上 tomcat 后重启项目则 ok。
