------解决思路----------------------
去 tomcat 文件夹下看看，项目是否生产成功。
------解决思路----------------------
看看是否服务端异常，或者页面本身就是空白
------解决思路----------------------
代码文件编码格式是什么，与你所在操作系统的文件编码格式是否相同。
例如源文件用的utf-8，但是在Windows下部署tomcat，这样文件编码格式不一致，可能会出现前端页面空白的现象。
解决办法是， tomcat/bin目录下的catalina.bat内， 修改 set JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG% 为 set JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG% -Dfile.encoding="UTF-8"
另外，启动日志中会打印一些file.encoding之类的日志，注意核对下。
------解决思路----------------------
你的tomcat8能启动成功？你换成7试试看看项目有问题吗？如果能行的话就是tomcat8本身有问题，或者说tomcat8的规范有地方变了
