问题:

The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path:[D:\javalea\javalearning\jdk8\bin;…

解决

1.下载 tcnative-1.dll,放在tomcat的bin目录下,没有解决问题,copy一份放在jdk的bin目录下也还是报错;

2.又注意到console中异常信息:

Description:An attempt was made to call the method javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String; but it does not exist.

发现tomcat-7中ServletContext中没有getVirtualServerName()方法:

3.将tomcat-8引入项目中,启动成功
