Java Web 环境搭建

1.下载JDK（Java8为例）

  • 下载地址：

      [Java SE Development Kit 8 - Downloads](http://www.oracle.com/technetwork/java/javase/downloads/j	dk8-downloads-2133151.html)

  [jdk-8u171-windows-x64.exe 一键下载地址](http://download.oracle.com/otn-pub/java/jdk/8u171-b11/512cd62ec5174c3487ac17c61aaa89e8/jdk-8u171-windows-x64.exe?AuthParam=1527129569_16da17421367f457979a306ac9a85b08)

  • 安装步骤参考如下：

      如何安装Java8？如何安装JDK8与配置环境变量_百度经验

    https://jingyan.baidu.com/article/7c6fb4282f1f6580642c90e1.html

  • 配置环境变量

    JAVA_HOME：C:\Program Files\Java\jdk1.8.0_171

    Path：%JAVA_HOME%\bin;

  • 验证

    C:\Users\Frank>where java
C:\Program Files\Java\jdk1.8.0_171\bin\java.exe

2.Maven安装

  • 官网下载：Maven – Download Apache Maven

  • 配置环境变量

    M2_HOME ：D:\Program Files\apache-maven-3.5.3

    Path ：%M2_HOME%\bin;

  • 验证（win+R 打开运行面板，然后输入CMD，打开命令提示符对话框，然后输入mvn -version）

    C:\Users\Frank>mvn -version
Apache Maven 3.5.3 (3383c37e1f9e9b3bc3df5050c29c8aff9f295297; 2018-02-25T03:49:05+08:00)
Maven home: D:\Program Files\apache-maven-3.5.3\bin\..
Java version: 1.8.0_171, vendor: Oracle Corporation
Java home: C:\Program Files\Java\jdk1.8.0_171\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

    出现如上版本号，则说明maven配置成功

3.IntelliJ IDEA 中配置Tomcat

部署线上环境

（1）使用cmd命令行，就进入项目根目录。mvn执行：mvn clean install package -Dmaven.test.skip=true，生成mango.jar文件

（2）上传mango.jar文件至目录/home/www/api.chengchijinfu.com

（3）已定义service，直接执行service mango start（启动），service mango stop（停止）

注意：默认端口号为8080，通过nginx反向代理，api.chengchijinfu.com域名指向8080端口

在PowerShell窗口下执行maven命令行报错：Unknown lifecycle phase ".test.skip=true". - CSDN博客 https://blog.csdn.net/wushengjun753/article/details/78973618

不要使用PowerShell命令行模式，使用 cmd 进入命令行执行：

mvn clean install package -Dmaven.test.skip=true

java -jar -Dserver.port=8090 mango.jar

nohup java -jar mango.jar > /dev/null 2>&1 &

!/bin/sh
nohup java -jar mango.jar > /dev/null 2>&1 &

ps -ef | grep mango.jar

kill -9 2576
