**在网上查了一下还是解决不了，然后又查了一下控制台，突然发现旁边的有个Servers的选项，就点进去看了一下，里面的Tomcat有我上次删的项目还在发布中。于是就把设个项目给移除了，再运行其它的项目的时候就没有出现错误了。
原来是因为当初用MyEClispe创建项目的时候，总是配置错误，被搞得心烦，就又创建了一个项目，把先前的一部分项目给移值过来然后就删了之前的项目，顺便把Myeclispe给重启了，再开启的时候发现不管运行哪个项目控制台都有出现错误，而且由于我习惯不把Tomcat给关掉，直接把Myclipse给重启来，经常会出现错误，一般解决的方法用上面的方法，若果还是解决不了的话，就再Myeclipse给关掉，然后调出任务管理器把有关java运行的进程都给关掉，我的进程在关掉MyEclipse之后还有一个javaw.exe,关掉它之后就在重启Myeclipse之后不会出现Mycelispe奔溃的现象了**
