当我打开IE时，输入http://localhost:8080/ 想不到的是，却报了404的错。

　　这想不至于吧，于时要重复了好几遍操作，结果都一样，很是奇怪，我想是不是tomcat 有什么问题，于是我是脱离eclipse，单独启动tomcat，启动完，刷新了页面，正常的tomcat页面出来了。

　　到此得出个问题，肯定是eclipse的问题了，应该不是软件的什么bug，可能是在某个地方设置有问题，从这个角度找下去，后来发现，原来在eclipse中的server中添加一个新的服务时，eclipse默认值有点小问题，

　　具体操作如下：

　　1、找到server操作窗口，双击下面的tomcat服务

　　２、在打开的设置中，将Server Locations的选项选成第二个“Use Tomcat installation (takes control of .........)”

　　现在刷新页面已经好了，能够正常出现大家熟悉的页面，接下你要做的，你懂的。

　　结束语：要是这个选项是灰的，不能够改，请删除，再重新试试，不要启动服务，刚添加tomcat时就切换到该窗口进行以下两步，就可以了。eclipse 将这项默认值选成第一个选项了。导致了今天的问题，希望能够给出现相同问题的人有所帮助！
