如何使用python代码启动服务器？

Question

我正在使用Stanford Core NLP Server。我想从python文件中启动它。

要从命令提示符启动它，我使用：

cd C:\ProgramData\Anaconda3\stanford-corenlp-full-2018-10-05
java -mx1g -cp "*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer -port 9000 -tiemout 15000

我试图从包含此代码的python文件中启动它：

import subprocess
subprocess.call([r'C:\Users\maell\PycharmProjects\Preprocessing\launch_NLP.bat'])

使用launch_NLP.bat包含：

cd C:\ProgramData\Anaconda3\stanford-corenlp-full-2018-10-05
java -mx1g -cp "*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer -port 9000 -tiemout 15000

输出是这样的：

C:\Users\maell\PycharmProjects\Pre-processing>cd                     
C:\ProgramData\Anaconda3\stanford-corenlp-full-2018-10-05 

C:\ProgramData\Anaconda3\stanford-corenlp-full-2018-10-05>java -mx1g -cp "*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer -port 9000 -tiemout 15000

如何让我的服务器运行而不是在线路过后关闭？

Answer 1

看起来像一个更简单的错误：

java.net.BindException: Address already in use: bind

要么终止在端口9000上运行的进程，要么在另一个端口上运行，它应该在下次运行。

Answer 2

java.net.BindException：已在使用的地址：bind

它说端口已经被使用，尝试使用launch_NLP.bat中的不同端口，如9001。
