This article is about why you want to use JRebel. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Why use JRebel?

There is a headache in the development process: every time you modify the background code, you need to redeploy the project to tomcat, and then start tomcat to rerun the project to view the modified results, wasting a lot of time. It is estimated that the development time taken by restarting the application server in one day is about 8% of the time, so it is necessary to introduce hot deployment in order to make reasonable use of the wasted time.

Download and install JRebel

1. Download address: link: http://pan.baidu.com/s/1i5E3WTv password: T79p

2. Get jrebel_6.4.3_update-site.zip (eclipse's jrebel plug-in package) and jrebel-6.4.3-crack.rar (jrebel's cracked package) after decompression.

3. Install the jrebel plug-in in eclipse (Mars.2):

Click "OK" to save when you are finished

Click "next"

Since then, the operation will not be repeated, but the choice to accept will appear, and the next step along the way can be completed.

After the installation is complete, you will be prompted to restart. Please select "Yes".

4. You can see "JRebel configuration" in help, indicating that the installation is successful, as shown in the following figure:

6. When you start eclipse again, you can see the figure below, which means that the crack and installation is successful.

7. After clicking "advanced", select the following figure
