java - NumberFormatException 的含义是什么以及如何解决它？

Question

我正在用 Python/WLST 编写代码，以自动连接、启动和停止 weblogic 中的托管服务器。当我启动 Python 时，出现以下错误。

异常的含义是什么？我该如何解决它？

WLST detected that the RuntimeMBeanServer is not enabled. This might happen if the RuntimeMBeanServer is disabled via the JMXMBean. Please ensure that this MBeanServer is enabled. Online WLST cannot function without this MBeanServer. This Exception occurred at Mon Jan 13 08:52:50 CET 2020. java.lang.NumberFormatException: For input string: "7001 "

The domain is unreacheable

代码:

-bash

#! /bin/sh

echo $(find /u01/ -name config.xml |grep -v bak| xargs grep -A4 AdminServer | grep listen-address | cut -d'>' -f 2 | cut -d'<' -f 1)

-Python/WLST

import sys
import os
from java.lang import System
import getopt
import time

values = os.popen(str('sh /home/oracle/scripts/wls/adminurl.sh'))
url = str("".join(map(str, values)))
port = ":7001"

adminurl = url.rstrip() + port + "\n"

def connectToDomain():
    try:
        if ServerName != "" or username == "" and password == "" and adminUrl == "":
            print (adminurl)
            connect(userConfigFile='/home/oracle/scripts/wls/userconfig.secure', userKeyFile='/home/oracle/scripts/wls/userkey.secure', url=adminurl, timeout=60000)

此外，RuntimeMBeanServer 已在管理服务器控制台中启用

可能是由adminurl = url.rstrip() + port + "\n"引起的。尝试不使用\n。

假设说明:adminUrl 稍后可以通过“:”符号分割成多个部分。在这种情况下，它会尝试将 7001\n 解析为 int，并且在 java.lang.Integer#parseInt(java.lang.String) 等方法中会失败
