为什么要用热部署？如果你公司使用微服务开发，你使用了一段时间的jenkins集成开发部署，你会发现即使有了这一套集成开发环境，假如我让你改个变量...你就需要跑一次jenkins,麻烦倒不麻烦，主要是花费太长的时间，所以开发阶段用远程服务热部署会更加方便和前端的对接，这也是这篇文章着重说的一点。

IntelliJ IDEA的JRebel插件包括JRebel代理并帮助您自动生成JRebel配置。它通过单击为应用程序和服务器启用JRebel，并改进了IDE中的调试支持。

这篇文章用英文来写(滑稽),希望你能看懂(滑稽)。

ok, let`s go

it can support many IDE tools that below:

1. Installation

1.1 Open the IntelliJ IDEA Settings
1.2. Select Plugins from the sections menu.
1.3. Press Browse plugin repositories... and locate the JRebel plugin.

1.4. restart IntelliJ IDEA

2. Activation

An excellent plugin is offen not free, and this is no exception.But i cant to teach you to buy it, of course that is the best way to get it, i will tall you how to crack this plugin.

2.1 open the JRebel control panel

you just need to fill in the infomation in these two boxes.

Filled in the first box is http://139.199.89.239:1008/d6bbb34d-84c4-4214-907e-26fc52f8e1b8 Filled in the second box is your email

Node: If the first box prompt expire, you can change to a uuid after the url.

OK, it is done when you click OK.

2.2 Change working model

if you just complete the first step, you also need to set this setting. Because in the case of working online, Exception will be detected at any time,(Will be detected as pirated).So follow me down:

After that, you will see it becomes like this:

OK, this is a success.

3. How to use on local

The only required configuration file is rebel.xml. This is used by JRebel to map the running application to the workspace. The good news is that IDE plugin can automate this configuration for you.

The meaning of the check mark is: Enable JRebel and generator therebel.xml

What`s in this file?

This file is automatically generated, Generally not need to manually modify .

<?xml version="1.0" encoding="UTF-8"?>

<!--
  This is the JRebel configuration file. It maps the running application to your IDE workspace, enabling JRebel reloading for this project.
  Refer to https://manuals.zeroturnaround.com/jrebel/standalone/config.html for more information.
-->
<application generated-by="intellij" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	</classpath>

</application>
Server startup

The JRebel plugin for IntelliJ IDEA includes dedicated launch buttons. These buttons are located on the main toolbar and on the navigation toolbar by default. You can also find these commands via the Run menu.

The first button launches the container with JRebel. The second button launches the container with JRebel in debug mode.

By launching the process from one of these buttons, the JRebel plugin will automatically add the appropriate command line parameters.

Node: You must have to use Run with JRebel or Debug with JRebel to start server, Because only then will it work, If you use Run mainor Debug main, sorry, you won`t be able to experience it !

4. How to use in remote servers

This chapter lists the steps required to set up JRebel remote server support for IntelliJ IDEA. You need a working, activated JRebel installation in your IDE. Please follow the instructions on how to install and configure JRebel for IntelliJ IDEA. If you have already set up JRebel, move on to step 1.

1. Enable JRebel remote server support on the server

Running JRebel on a remote server requires the JRebel agent and a special launch parameter. Follow these steps to do this.

  1. Open Settings > JRebel > Startup.
  2. Select Run on a remote server.
  3. Use the drop-down menus to specify your remote server configuration.
  4. Follow the instructions displayed.
1.1 if remote server is tomcat

if remote server is tomcat

1.2 If remote server is springboot 2.x

If remote server is springboot2.x

2. Server Config
2.1 download and install jrebel server
[root@FantJ jrebel]# curl -O http://dl.zeroturnaround.com/jrebel-stable-nosetup.zip
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 21.2M  100 21.2M    0     0  2584k      0  0:00:08  0:00:08 --:--:-- 4778k
[root@FantJ jrebel]# unzip jrebel-stable-nosetup.zip
2.2 start up

because I am using the remote service of springboot 2.x, so I execute this statement :java "-agentpath:[JRebel root folder]/lib/libjrebel64.so" -Drebel.remoting_plugin=true -jar myapp-boot.jar

[root@FantJ test-jenkins]# java "-agentpath:/home/fantj/jrebel/jrebel/lib/libjrebel64.so" -Drebel.remoting_plugin=true -jar web.jar

......

if you want it run in the background.

nohup java "-agentpath:/home/fantj/jrebel/jrebel/lib/libjrebel64.so" -Drebel.remoting_plugin=true -jar web.jar > nohup.out &

you always can view its logs:

tail -f nohup.out

3. create a connect

Node: You may also notice that is not safe, because there is not need any certification. Official provides a method: java -jar jrebel.jar -set-remote-password <NewPassword>, You should set it up , I will not make a demo here.

Press OK to store the new remote server.

4. Configure modules for remote server support

  1. Open View > Tool Windows > JRebel. The JRebel Modules view is opened in IntelliJ IDEA:
  1. Select the checkbox for your desired modules.

  1. Build and redeploy your application containing the rebel-remote.xml configuration file to the remote server.

  1. You`re done, congratulations!
