使用Eclipse启动Tomcat8时出现 'Starting Tomcat v8.0 Server at localhost' has encountered a problem.

• 问题1：
  使用Eclipse启动Tomcat8时出现 ‘Starting Tomcat v8.0 Server at localhost’ has encountered a problem.Several ports (8005, 8009，8080) required by Tomcat v6.0 Server at localhost are already in use. The server may already be running in another process, or a system process may be using the port.To start this server you will need to stop the other process or change the port number(s).

• 解决：启动任务管理器，结束javaw.exe进程

• 问题3：ajax在google浏览器上失效的解决方案

• 解决：google chrome是由于某种安全策略的需要，禁止访问本地的ajax资源！使用本机IP来访问SERVER端，而不要使用127.0.0.1或者是localhost
