从零构建可视化jar包部署平台JarManage - 服务器托管|北京服务器租用|机房托管租用|IDC托管租用|机房机柜带宽租用-价格及费用咨询

项目背景

在java项目部署过程中，由于内外部各种因素，可能会遇到一些感觉操作不便捷的场景，例如

jar包未随系统自动启动需要每次手动重启
系统vpn堡垒机多重防御更新繁琐
系统无图形化界面命令行操作复杂
等等……

在工作中之前也总结了windows的Jar包部署工具与linux下的jar包自动化部署脚本，这次就想着否能将二者统一结合，本着简单/高效/功能专一的原则，做出一

个可视化jar包部署平台，JarManage应运而生

功能介绍

项目地址：https://gitee.com/code2roc/jar-manage

支持在线创建项目，上传Jar包，自动备份，配置启动参数，注册系统服务，查看启动日志等功能，具有以下优点

基于servlet开发，依赖简洁，部署包10MB左右
结合嵌入式tomcat一键部署，无外部容器依赖
使用h2db存储数据，无外部数据库依赖
适配windows/linux平台，满足多种环境
具体项目经平台部署后自动注册系统服务，无需担心服务器重启

系统架构图如下

技术分析

平台识别

首先通过系统os识别是windows平台还是linux平台

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

通过system-release文件识别部分基于CentOS开发的Linux系统

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;
}

通过issue文件识别部分基于Ubuntu/Debian开发的Linux系统

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注册服务

通过sc query命令判断服务状态

    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;
    }

通过winsw这个开源项目配置exe和xml文件将jar包注册为windows服务，项目地址：https://github.com/winsw/winsw/

linux注册服务

通过systemctl status命令判断服务状态

    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;
    }

通过拷贝service文件到systemd/system目录下注册linux服务

yml配置文件识别

maven配置

        
            org.yaml
            snakeyaml
            1.26

配置文件

jarmanage:
  port: 8555
  username: admin
  password: abcd@1234
  backupcount: 5

工具类

    public static String getConfigValue(String configName){
        String configValue = "";
        try{
            Yaml yaml = new Yaml();
            InputStream resourceAsStream = new FileInputStream(new File("resources"+File.separator+"application.yml"));
            Map obj = yaml.load(resourceAsStream);
            Map param = (Map) obj.get("jarmanage");
            configValue = ConvertUtil.convert2String(param.get(configName));
        }catch (Exception e){
            LogUtil.error(e);
        }
        return configValue;
    }

h2database使用

maven引用

        
            com.h2database
            h2
            2.1.214

工具类

    public static Connection getConnection() throws Exception {
        File file = new File("database");
        Connection conn = DriverManager.getConnection("jdbc:h2:file:" + file.getAbsolutePath() + File.separator + "manage", "root", "abcd@1234");
        return conn;
    }
    
    public static void executeSQL(String sql) {
        try {
            Connection conn = getConnection();
            Statement stmt = conn.createStatement();
            stmt.execute(sql);
            stmt.close();
            conn.close();
        } catch (Exception e) {
            LogUtil.error(e);
        }
    }

servelt内置tomcat打包

maven引用

        
            org.apache.tomcat.embed
            tomcat-embed-core
            9.0.35
        
        
            org.apache.tomcat.embed
            tomcat-embed-el
            9.0.35
        
        
            org.apache.tomcat.embed
            tomcat-embed-jasper
            9.0.35

手动启动

            //启动tomcat服务
            // 1.创建一个内嵌的Tomcat
            Tomcat tomcat = new Tomcat();
            // 2.设置Tomcat端口
            tomcat.setPort(8555);
            // 3.设置工作目录,tomcat需要使用这个目录进行写一些东西
            final String baseDir = "workspace" + File.separator;
            tomcat.setBaseDir(baseDir);
            tomcat.getHost().setAutoDeploy(false);
            // 4. 设置webapp资源路径
            String webappDirLocation = "webapp" + File.separator;
            StandardContext ctx = (StandardContext) tomcat.addWebapp("/", new File(webappDirLocation).getAbsolutePath());
            // 5. 设置上下文路每径
            String contextPath = "";
            ctx.setPath(contextPath);
            ctx.addLifecycleListener(new Tomcat.FixContextListener());
            ctx.setName("jar-manage");
            tomcat.getHost().addChild(ctx);
            //6.启动
            tomcat.getConnector();
            tomcat.start();
            tomcat.getServer().await();

打包包含引用类库，自定义配置xml，指定运行class
