Jrebel installation instructions

If you are interested in Java Development, refer.

In the development environment, Tomcat's support for hot deployment is still relatively weak, resulting in a large waste of time in the development process to restart the service. To improve development efficiency, we decided to introduce jrebel, which had relatively comprehensive support for the hot deployment.

Although jrebel officially claims that there is no memory leakage problem when using jrebel, it certainly occupies a certain amount of resources, so it does not consider using hot deployment in the formal environment. In addition to Tomcat, jrebel also supports jetty, resin, and weblogic. This article describes the Tomcat + eclipse + spring + struts2 environment. After using jrebel, it is expected that it will be enough after the developer starts Tomcat once in the morning.

PS. Rebel provides the free community edition. For details, see:
