這篇文章主要為大家介紹了從零構(gòu)建可視化jar包部署平臺(tái)JarManage教程詳解，有需要的朋友可以借鑒參考下，希望能夠有所幫助，祝大家多多進(jìn)步，早日升職加薪

項(xiàng)目背景

在java項(xiàng)目部署過程中，由于內(nèi)外部各種因素，可能會(huì)遇到一些感覺操作不便捷的場(chǎng)景，例如

jar包未隨系統(tǒng)自動(dòng)啟動(dòng)需要每次手動(dòng)重啟
系統(tǒng)vpn堡壘機(jī)多重防御更新繁瑣
系統(tǒng)無圖形化界面命令行操作復(fù)雜
等等......

在工作中之前也總結(jié)了windows的Jar包部署工具與linux下的jar包自動(dòng)化部署腳本，這次就想著否能將二者統(tǒng)一結(jié)合，本著簡(jiǎn)單/高效/功能專一的原則，做出一

個(gè)可視化jar包部署平臺(tái)，JarManage應(yīng)運(yùn)而生

功能介紹

項(xiàng)目地址：https://gitee.com/code2roc/jar-manage

支持在線創(chuàng)建項(xiàng)目，上傳Jar包，自動(dòng)備份，配置啟動(dòng)參數(shù)，注冊(cè)系統(tǒng)服務(wù)，查看啟動(dòng)日志等功能，具有以下優(yōu)點(diǎn)

基于servlet開發(fā)，依賴簡(jiǎn)潔，部署包10MB左右
結(jié)合嵌入式tomcat一鍵部署，無外部容器依賴
使用h2db存儲(chǔ)數(shù)據(jù)，無外部數(shù)據(jù)庫依賴
適配windows/linux平臺(tái)，滿足多種環(huán)境
具體項(xiàng)目經(jīng)平臺(tái)部署后自動(dòng)注冊(cè)系統(tǒng)服務(wù)，無需擔(dān)心服務(wù)器重啟

系統(tǒng)架構(gòu)圖如下

系統(tǒng)截圖展示

技術(shù)分析

平臺(tái)識(shí)別

首先通過系統(tǒng)os識(shí)別是windows平臺(tái)還是linux平臺(tái)

String os = System.getProperty("os.name").toLowerCase();
if (os.startsWith("win")) {
   platform = DepolyPlatform.Windows;
}

通過system-release文件識(shí)別部分基于CentOS開發(fā)的Linux系統(tǒng)

String command = "cat /etc/system-release";
String result = CMDUtil.executeLinuxCommand(command);
if (result.startsWith("Red Hat")) {
   platform = DepolyPlatform.LinuxRedHat;
} else if (result.startsWith("CentOS")) {
   platform = DepolyPlatform.LinuxCentOS;
} else if (result.startsWith("openEuler")) {
   platform = DepolyPlatform.LinuxOpenEuler;
}

通過issue文件識(shí)別部分基于Ubuntu/Debian開發(fā)的Linux系統(tǒng)

command = "cat /etc/issue";
result = CMDUtil.executeLinuxCommand(command);
if (!StringUtil.isEmpty(result)) {
  if (result.startsWith("Ubuntu")) {
     platform = DepolyPlatform.LinuxUbuntu;
} else if (result.startsWith("Debian")) {
      platform = DepolyPlatform.LinuxDebian;
   }
}

windows注冊(cè)服務(wù)

通過sc query命令判斷服務(wù)狀態(tài)

public String getStatus(String serviceName) {
        String status = DepolyStatus.UnInstall;
        try {
            String command = "sc query " + serviceName;
            String commandResultFilePath = CMDUtil.executeWindowCommandStoreFile(command);
            BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(commandResultFilePath)));
            String line = reader.readLine();
            while (line != null) {
                if (line.trim().startsWith("STATE")) {
                    if (line.trim().substring(line.trim().indexOf(":") + 1, line.trim().indexOf(":") + 4).trim().equals("1"))
                        status = DepolyStatus.Stopped;
                    else if (line.trim().substring(line.trim().indexOf(":") + 1, line.trim().indexOf(":") + 4).trim().equals("2"))
                        status = DepolyStatus.Startting;
                    else if (line.trim().substring(line.trim().indexOf(":") + 1, line.trim().indexOf(":") + 4).trim().equals("3"))
                        status = DepolyStatus.Stopping;
                    else if (line.trim().substring(line.trim().indexOf(":") + 1, line.trim().indexOf(":") + 4).trim().equals("4"))
                        status = DepolyStatus.Running;
                }
                line = reader.readLine();
            }
        } catch (IOException e) {
            LogUtil.error(e);
        }
        return status;
    }

通過winsw這個(gè)開源項(xiàng)目配置exe和xml文件將jar包注冊(cè)為windows服務(wù)，項(xiàng)目地址：https://github.com/winsw/winsw/

linux注冊(cè)服務(wù)

通過systemctl status命令判斷服務(wù)狀態(tài)

public String getStatus(String serviceName) {
        String status = DepolyStatus.UnInstall;
        try {
            String command = "systemctl status " + serviceName;
            String commandResultFilePath = CMDUtil.executeLinuxCommandWithStore(command);
            BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(commandResultFilePath)));
            String line = reader.readLine();
            while (line != null) {
                if (line.trim().startsWith("Active")) {
                    if (line.trim().indexOf("inactive (dead)") > 0)
                        status = DepolyStatus.Stopped;
                    else if (line.trim().indexOf("active (running)") > 0)
                        status = DepolyStatus.Running;
                    else if (line.trim().indexOf("failed") > 0)
                        status = DepolyStatus.Stopped;
                }
                line = reader.readLine();
            }
        } catch (IOException e) {
            LogUtil.error(e);
        }
        return status;
    }

通過拷貝service文件到systemd/system目錄下注冊(cè)linux服務(wù)
