最近用java写了个小项目,想要部署到服务器,于是买了个Windows server2012,但是不知道怎么部署,后来才知道需要配置java运行环境.经过一番研究最终搞定了.下边是我的个人总结,由于是第一次部署服务器,所以有些地方不够完美. 第一步:安装jdk 下载 这个可以到oracle官网下载,下载步骤如下:https://jingyan.baidu.com/article/c1465413b54ec40bfcfc4cdd.html   最新版的oracle页面不是这样的,直接搜jdk,找到

debug运行java程序报错 ERROR: transport error 202: connect failed: Connection timed out ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510) JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [debugInit.c:750] 错误

报错:Unable to open debugger port (127.0.0.1:63959): java.net.SocketException "socket closed",编译过来就是无法打开调试器端口,套接字已关闭 这台笔记本操作系统是win10专业工作站版,debug启动项目,provide项目完美启动成功,然后consumer项目报错:Unable to open debugger port (127.0.0.1:63959): java.net.SocketExce

运行Java程序的时候,报错:EXCEPTION_ACCESS_VIOLATION (0xc0000005): 根据原网页的说明: EXCEPTION_ACCESS_VIOLATION In rare circumstances, a Java program could stop with a message similar to the following: An unexpected error has been detected by HotSpot Virtual Machine: E

启动node程序时,报如下错误:

首先用记事本写一个最简单的Java代码,我把文件保存在桌面的HelloWorld文件夹中,这里将记事本的名称改为HelloWorld.java public class HelloWorld{ public static void main(String args[]){ System.out.println("hello!"); } } 其次用Win+R键,输入cmd打开命令提示符 系统默认位于 C:\Users\西瓜 用命令 cd desktop\HelloWorld  转到该目录

首先,当在运行java程序出现这个错误时,首先考虑是不是路径或者未指定正确的包名,例如当运行下面这个文件时: package cn.wgh.socket; public class HelloWorld { public static void main(String[] args) { System.out.println("Hello world!"); } } 应该要将cmd的目录设置到项目的根目录后,再来进行运行操作,比如说我的项目目录是这样的: E:\Work\MyJava\

在linux下编译java程序,执行javac编译生成class文件时,在centos7终端输入如,javac hello.java    会提示未找到指令,但用java -verison测试环境变量是没问题的 百度了好久,说的很复杂,重新再linux配置环境变量,输入 vi /etc/profile进入,添加以下代码: export JAVA_HOME=/usr/local/jdk1.8.0_144 export PATH=$JAVA_HOME/bin:$PATH export CLASSPA
