远程调用cmd更新本地jar

最近遇到一个项目需求需要实现远程更新，但是本地项目无法更新自己，这让博主很是头疼，既然自己无法更新自己的话，那就自建新的项目，通过本地项目来调用新项目接口来更新本地项目。

代码如下：

/**
     * 重启完成更新
     */
    public boolean restart() {
        log.info("restart");
        String command = "cmd /c start C:\\rct\\winsw\\rct\\update.bat";
        //测试
        String distName = "dist";
        String jarName = "rct-demo-1.0.jar";
        String bat;
        if (type.equals("dist")) {
            log.info("dist");
            bat = "@echo off\n" +
                    "%1 mshta vbscript:CreateObject(\"Shell.Application\").ShellExecute(\"cmd.exe\",\"/c %~s0 ::\",\"\",\"runas\",1)(window.close)&&exit\n" +
                    "cd /d \"%~dp0\"\n" +
                    "net stop \"" + webService + "\"" + "\n" +
                    "rmdir /S /Q " + targetFile + "\\" + "dist" + "\n" +
                    "xcopy /Y /E /i " + sourceFile + "\\" + distName + " " + targetFile + "\\" + distName + "\n" +
                    "net start \"" + webService + "\"";
        } else if (type.equals("jar")) {
            log.info("jar");
            bat = "@echo off\n" +
                    "%1 mshta vbscript:CreateObject(\"Shell.Application\").ShellExecute(\"cmd.exe\",\"/c %~s0 ::\",\"\",\"runas\",1)(window.close)&&exit\n" +
                    "cd /d \"%~dp0\"\n" +
                    "net stop \"" + jarService + "\"" + "\n" +
                    "xcopy /Y /E /i " + sourceFile + "\\" + jarName + " " + targetFile + "\\" + jarName + "\n" +
                    "net start \"" + jarService + "\"";
        } else {
            log.info("all");
            bat = "@echo off\n" +
                    "%1 mshta vbscript:CreateObject(\"Shell.Application\").ShellExecute(\"cmd.exe\",\"/c %~s0 ::\",\"\",\"runas\",1)(window.close)&&exit\n" +
                    "cd /d \"%~dp0\"\n" +
                    "net stop \"" + jarService + "\"" + "\n" +
                    "net stop \"" + webService + "\"" + "\n" +
                    "rmdir /S /Q " + targetFile + "\\" + "dist" + "\n" +
                    "xcopy /Y /E /i " + sourceFile + "\\" + jarName + " " + targetFile + "\\" + jarName + "\n" +
                    "xcopy /Y /E /i " + sourceFile + "\\" + distName + " " + targetFile + "\\" + distName + "\n" +
                    "net start \"" + jarService + "\"" + "\n" +
                    "net start \"" + webService + "\"";
        }
        creatBat(bat);
        log.info("cmd exec");
        try {
            if (HttpUtil.isConnect(checkUrl)) {
                updated = true;
                try {
                    Thread.sleep(5000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                HttpUtil.HttpClientPost(cmdUrl, command);
            } else {
                errored = true;
                return false;
            }
        } catch (Exception e) {
            log.error("http请求异常");
            e.printStackTrace();
            errored = true;
            return false;
        }
        log.info("cmd success");
        return true;
    }

    public void creatBat(String bat) {
        FileWriter fw = null;
        try {
            fw = new FileWriter("C:\\rct\\winsw\\rct\\update.bat");
            fw.write(bat);
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (fw != null) {
                try {
                    fw.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
