项目结构如下图

技术分享

一:系统环境

本机:10.4.18.3

服务器: 10.4.18.4,用户名: web02


二:初始化服务器环境

在服务器上的家目录创建目录deploy,deploy/profile

mkdir -p /home/web01/deploy

mkdir -p /home/web02/deploy/profile

安装jdk 

export JAVA_HOME=/home/web02/jdk1.7.0_67


三:源代码(这里演示了一个自己写的http web服务器)

com.lala.server.Server.java

package com.lala.server;

import java.io.IOException;
import java.io.OutputStream;
import java.net.InetSocketAddress;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;
import java.util.concurrent.Executors;

import com.google.gson.Gson;
import com.sun.net.httpserver.Headers;
import com.sun.net.httpserver.HttpExchange;
import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpServer;

public class Server 
{
	public void httpserverService() throws IOException 
	{  
		String hr = "======================================================================";
		System.out.println("");
		System.out.println(hr);
		int port = 17002;
		InetSocketAddress addr = new InetSocketAddress(port);   
		System.out.println("http server start at " + port + " ...");
        HttpServer server = HttpServer.create(addr, 0);   
        server.createContext("/gson", new GsonHandler());   
        System.out.println("create path /gson");
        server.createContext("/index", new MyHandler());   
        System.out.println("create path /index");
        server.setExecutor(Executors.newCachedThreadPool());   
        server.start();   
        System.out.println("start http server success at port [" + port + "]");
        System.out.println(hr);
	}
}

class MyHandler implements HttpHandler 
{
	@SuppressWarnings("deprecation")
	public void handle(HttpExchange exchange) throws IOException 
	{
		Headers responseHeaders = exchange.getResponseHeaders();   
		OutputStream responseBody = exchange.getResponseBody();   
        responseHeaders.set("Content-Type", "text/html;charset=UTF-8");   
        String html = "<h1>你好,现在是:" + new Date().toLocaleString() + "</h1>";
        exchange.sendResponseHeaders(200, html.getBytes().length);
        responseBody.write(html.getBytes());
        responseBody.close();
	}
}

class GsonHandler implements HttpHandler 
{
	public void handle(HttpExchange exchange) throws IOException 
	{
		Headers responseHeaders = exchange.getResponseHeaders();   
		OutputStream responseBody = exchange.getResponseBody();   
        responseHeaders.set("Content-Type", "application/json;charset=UTF-8");   
        Map<String, String> map = new HashMap<String, String>();
		map.put("id", "10083");
		map.put("name", "CMCC");
		map.put("nick", "china mobile");
		String html = null;
		try
		{
			Gson g = new Gson();
			html = g.toJson(map);
		}catch(Exception e)
		{
			e.printStackTrace();
			html = "{code : 500, msg : '"+e.getMessage()+"'}";
		}
        exchange.sendResponseHeaders(200, html.getBytes().length);
        responseBody.write(html.getBytes());
        responseBody.close();
	}
}


com.lala.server.Start.java

package com.lala.server;

import java.io.IOException;

public class Start 
{
	public static void main(String[] args) throws IOException 
	{
		new Server().httpserverService();
	}
}

#1. 首先调用checkpid函数,刷新$psid全局变量
#2. 如果程序已经启动($psid不等于0),则提示程序已启动
#3. 如果程序没有被启动,则执行启动命令行
#4. 启动命令执行后,再次调用checkpid函数
#5. 如果步骤4的结果能够确认程序的pid,则打印[OK],否则打印[Failed]

#说明:
#1. 首先调用checkpid函数,刷新$psid全局变量
#2. 如果程序已经启动($psid不等于0),则开始执行停止,否则,提示程序未运行
#3. 使用kill -9 pid命令进行强制杀死进程
#4. 执行kill命令行紧接其后,马上查看上一句命令的返回值: $?
#5. 如果步骤4的结果$?等于0,则打印[OK],否则打印[Failed]
#6. 为了防止java程序被启动多次,这里增加反复检查进程,反复杀死的处理(递归调用stop)。
#注意: 在shell编程中,"$?" 表示上一句命令或者一个函数的返回值

四:注意事项

1:pom.xml里面的/home/web02/deploy/profile/current/lib/需要和服务器的发布目录保持一致,否则会找不到jar

2:pom.xml里面的profiles配置用法,请参照我的上一篇博客


五:用法

去到项目的根目录执行

sh deploy.sh 按照提示输入即可自动部署(发布,重起)

发布成功之后,在浏览器中输入

http://10.4.18.4:17002/index

http://10.4.18.4:17002/gson

即可看到结果

使用shell脚本自动部署(发布,重起)maven(java)项目
