点点滴滴

最近老是有程序占用JVM的端口号，后来上网查询资料很快给解决了，现在总结一下

严重: Error starting endpoint

方法：

1、Windows平台
在windows命令行窗口下执行：
1.查看所有的端口占用情况

C:\>netstat -ano

  协议    本地地址                     外部地址               状态                   PID

  TCP    127.0.0.1:1434         0.0.0.0:0              LISTENING       3236
  TCP    127.0.0.1:5679         0.0.0.0:0              LISTENING       4168
  TCP    127.0.0.1:7438         0.0.0.0:0              LISTENING       4168
  TCP    127.0.0.1:8015         0.0.0.0:0              LISTENING       1456
  TCP    192.168.3.230:139      0.0.0.0:0              LISTENING       4
  TCP    192.168.3.230:1957     220.181.31.225:443     ESTABLISHED     3068
  TCP    192.168.3.230:2020     183.62.96.189:1522     ESTABLISHED     1456
  TCP    192.168.3.230:2927     117.79.91.18:80        ESTABLISHED     4732
  TCP    192.168.3.230:2929     117.79.91.18:80        ESTABLISHED     4732
  TCP    192.168.3.230:2930     117.79.91.18:80        ESTABLISHED     4732
  TCP    192.168.3.230:2931     117.79.91.18:80        ESTABLISHED     4732

 

2.查看指定端口的占用情况
C:\>netstat -aon|findstr "9050"

  协议    本地地址                     外部地址               状态                   PID

  TCP    127.0.0.1:9050         0.0.0.0:0              LISTENING       2016

P: 看到了吗，端口被进程号为2016的进程占用，继续执行下面命令： （也可以去任务管理器中查看pid对应的进程）

3.查看PID对应的进程
C:\>tasklist|findstr "2016"

 映像名称                       PID 会话名              会话#       内存使用
 ========================= ======== ================
  tor.exe                     2016 Console                 0     16,064 K

P:很清楚吧，tor占用了你的端口。

 

4.结束该进程

C:\>taskkill /f /t /im tor.exe或者打开任务管理器结束该进程

但是如果JVM多次被占用，可以确定是被javaw.exe占用了，只需打开任务管理器，结束内存较小的那个javaw.exe就行了。
