Windows 7下端口占用的进程分析

以你之姓@ 2022-07-17 15:26 213阅读 0赞

引言： 在windows下进行开发之时，经常会发现某端口被占用，一般情况下，只能重启系统来草率解决问题，这里我们将通过进程的停掉，释放端口的方式来解决这个问题。

1.  问题的提出

在上次调试应用过程中，某进程貌似未被正确的停掉，故在新启动某个应用的过程中，报出了如下的错误信息：

2016-09-01 10:51:43.525 ERROR 11420 --- [  restartedMain] o.apache.catalina.core.StandardService   : Failed to start connector [Connector[HTTP/1.1-8080]]

从错误信息来看，是8080 端口被占用了，故由于端口冲突，tomcat服务无法正常启动

2.  找到占用端口的进程

>>  netstat -ano | findStr 8080

![Center][]

最后一列，列出了目前的进程pid

3.  基于进程监控器找到相应的进程信息

>>  tasklist | findStr 10184

![Center 1][]

>>  打开进程管理器

![Center 2][]

4.  杀掉进程，重启应用即可正常使用了。
