部署到apache-tomcat-7.0.68时报错如下，换成apache-tomcat-8.0.9解决

另外springboot项目打成war包部署到tomcat时需要改变启动方式，否则运行tomcat时war包只会解压，但是加载不了

部署到外部tomcat时，注意pom.xml配置，否则会报错

springboot项目使用jsp页面时会添加以下依赖，但是在外部tomcat运行时会报错
因为tomcat /lib下自带的jar包（jasper.jar，jsp-api.jar等）会跟war包项目路径/lib下的解析jsp的jar包冲突
删除项目路径/lib下的相关jar包即可，如下图

默认配置下就可以通过http://localhost:8080/war包名/@RequestMapping.value访问了， 另外部署到tomcat后静态资源（resources下的js文件）访问不到的问题还没解决。。。
