Acerca de
Jrebel is a Java development tool that enables hot reloading of classes without restarting the JVM. This mind map covers key aspects of JRebel, including its background, environment setup, configuration for Jetty, differences between hot swap and JRebel, and working with data sources. It explains that classes cannot be changed once loaded into the container (JVM), and that JRebel creates a new class and associates it with a holder when methods are added or modified, achieving dynamic behavior changes. The template includes environment variable exports like JAVA_OPTS and MAVEN_OPTS, and configuration for the maven-jetty-plugin. It contrasts JRebel with HotSwap, noting that HotSwap only supports method body changes, while JRebel handles method and signature modifications. The 'Working with ds' section covers setting project path using module compile output path and running gradle reaMakeDev to generate rebel.xml.
