Server Tomcat v7.0 Server at localhost failed to start解决历程

 运行Tomcat出现如图所示的问题，

参考的这篇文章（https://blog.youkuaiyun.com/kwc1314/article/details/79086519/）的4种方法进行尝试解决： 

方法1：把你工作空间文件夹下的如下路径打开:<workspace>\.metadata\.plugins\org.eclipse.core.resources

然后删除 .snap 文件，我在eclipse打开的情况下有这个.snap文件

最后没有发现这个文件：

因此 继续尝试

方法2：把你工作空间文件夹下的如下路径打开：<workspace>\.metadata\.plugins\org.eclipse.wst.server.core

删除里面的temp*文件夹，删除后重启eclipse，tomcat就可以用了

还是没有存在这个文件，尝试

方法3：

 在server视图窗口中 把tomactt删除 然后再从新添加tomcat 之后再重新在启动你的web项目

还是不行： 

方法4：打开任务管理器，找到javax.exe，右键结束进程，重启eclipse，tomcat就可以用了

 压根就没找到javax那个应用，重启eclipse再说：

还是报错。 

尝试换一个新的Tomcat，因为用的Tomcat之前用过很多次，想换个新的：

 还是不行，我还是看看问题报错的具体原因：

问题应该是我的Tomcat的监听器的缘故，尝试一下：

找到Tomcat的配置文件

 

<Server port="8005" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
  <!-- Security listener. Documentation at /docs/config/listeners.html
  <Listener className="org.apache.catalina.security.SecurityListener" />
  -->
  <!--APR library loader. Documentation at /docs/apr.html -->
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  <!--Initialize Jasper prior to webapps are loaded. Documentation at /docs/jasper-howto.html -->
  <Listener className="org.apache.catalina.core.JasperListener" />
  <!-- Prevent memory leaks due to use of particular java/javax APIs-->
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

由于报错为找不到那个监听器，我们就直接注释掉，完美解决
