tomcat里面配置文件写上内存大小，在重启
1.确定你的eclipse是否只有一个项目启动；
2.project clean 一下；
3.tomcat clean;
4,再启动看一下，如果不行，那就是你代码的问题了，这需要仔细检查
要学会排错，先判断有没有多次启动了tomcat服务器（有时候会启动多个，运行一个进程的时候要把其他的进程都关掉）。
还是不行的话，关掉eclipse，在tomcat的安装包bin里启动startup.sh，再在浏览器中输入http://localhost/8080试试能不能正常启动。
如果正常启动了就不是服务器的问题，检查一下代码，有没有问题。
可能安装的项目大了，在启动时，手动设置一下内存大小
