One of the problems we often encounter with eclipse development is that you need to restart Tomcat after you modify the class file to take effect, even if you use some Tomcat plug-ins, sometimes you modify the method name or add a class, and you restart it. Using the Jolt Award-winning work Jrebel, you can easily implement the JVM thermal deployment, regardless of any circumstances, modify the class without restarting Tomcat
First, download Jrebel, go to http://fly-hyp.javaeye.com/blog/350498, and configure eclipse
Add-noverify-javaagent:d:/youpath/jrebel.jar to the startup parameter here you need to change the path to your native, and sometimes you need to place the Jrebel.jar in the project's Jar directory
You can then turn off automatic restart of the server settings so that every time you modify the file eclipse will help you restart your service.
