原因分析
首先我们要了解到Tomcat出现问题，往往都是配置文件出现了问题，经常是web.xml、server.xml。本次错误的有效提示信息如下：
Caused by: java.lang.IllegalArgumentException: 指定的主资源集 [E:\devSoftware\apache-tomcat-8.5.58\webapps\myFileSystem] 无效
为啥我会觉得是这句呢？因为别的也看不到，当我去查看提示信息中的无效资源“myFileSystem”时发现它并不存在，这是我就更加确信我的判断，于是我找到了如下这篇博文：解决myeclipse中启动Tomcat失败以及指定的主资源集无效
在看完博文后我查看了自己的server.xml文件，找到了如下这句代码，估计本次的原因应该就是Context的问题了。
<Context docBase="myFileSystem" path="/myFileSystem" reloadable="true" source="org.eclipse.jst.jee.server:myFileSystem"/></Host>
为了处理问题我查找了有关context 中的 docBase 的博文：tomcat 配置文件 conf/server.xml 中的 appBase和docBase
看到上面这篇博文时已经找到了解决方案，但是为了更好的处理今后的Tomcat问题，建议阅读如下有关于server.xml的详解博文：Tomcat中server.xml配置详解
解决方案
1.找到Tomcat安装目录下的cong\server.xml 打开文档找到最尾部的如下代码
2. eclipse中已经创建好sever的话修改server项目下的server.xml
<Context docBase="myFileSystem" path="/myFileSystem" reloadable="true" source="org.eclipse.jst.jee.server:myFileSystem"/></Host>
这句代码就是问题的原因所在，将它删除或者注释掉就解决问题了。
