Now you should be good to go to either login or register for an account. It will spew out lots of startup messages to the log, which should end with a message of the form: Start a terminal to watch for monitoring the logs during startup (if this is the first time you're starting Tomcat you'll need to do this after startup since the log won't yet exist): tail -f $TOMCAT_HOME/logs/catalina.out If it is running, issue a shutdown/kill until it succumbs (see above). Start Tomcat with JRebel and jpda debuggingīefore issuing the Tomcat start command, make sure it is really not running. If you see one, try to kill the process, ps again, etc. Look for processes with args relating to Tomcat. Make sure it's really dead: ps auwwx | grep java Issue the shutdown command: cd $TOMCAT_HOME
Linux, if following directory pattern from Amazon EC2 setup example export TOMCAT_HOME=/opt/tomcat/home Shutdown Tomcatīefore trying to shutdown Tomcat, make sure the IntelliJ IDEA debugger doesn't have the process broken at a breakpoint. Mac: export TOMCAT_HOME=/Library/Tomcat/Home
#JREBEL SETUP INSTALL#
Setup Mac setup JRebel setup jrebel.tar rebel.xml Additional Tomcat setup Install IntelliJ IDEA IntelliJ IDEA settings Care and feeding of Tomcat Setup TOMCAT_HOME
#JREBEL SETUP UPDATE#
After loading, The hot update effect has been realized.
#JREBEL SETUP CODE#
Modify the code （ Only tested Java Code changes ） after, Press shortcut key Ctrl + Shift + F9, After running, you will be prompted whether to reload if there are changes, choose yes. Modify some code in the running project ,Jrebel Will automatically monitor the changed code, The output log is as follows : When running a project, choice Jrebel run payplatform-admin perhaps Jrebel Debug payplatform-admin (payplatform-admin Name the project you want to run ) To run a project, click the button in the red box in the figure, You can run ： Press shortcut key Ctrl+Shift+Alt+/, choice Registry, Pop up the following interfaceĬ.app.running The option must be checked Use Shortcut key ctrl+shift+A, Search for ：registry Open runtime compilation Set up .app.running To achieve hot deployment, The first thing we need to do is Intellij Set as follows ：ġ, because JRebel It's real-time monitoring class File changes to achieve hot deployment, So in idea In this environment, you need to turn on the automatic mutation function to modify it at any time, Effective from time to timeĢ.
Step four ： open jrebel Panel as shown below, choice Connect to online licensing serviceĬlick on Activate JRebel After a short time, The interface is as follows ：įollow the instructions Next, The following interface is ,Jrebel Plug in installed successfully. Step three ： On-line GUID Address ： Online generation GUID Step two ： Click on Install After installation ,restart Restart Intellij idea, Installation step one : file->settings->plugins-> Search in the search box Rrebel Here's the picture : įor now idea The best solution for hot deployment is to install JRebel plug-in unit. IDEA Upper native does not support hot deployment, Generally updated Java Restart the file manually Tomcat The server, To take effect, Waste time waste life. JRebel Is a JVM plug-in unit, It makes the Java No need to restart the system after the code is modified, Immediate effect. When a programmer makes changes to any class or resource in the development environment, This change will be directly reflected in the deployed application, This skips the process of building and deploying, A lot of deployment time can be saved. JRebel Enables you to see the code separately in real time 、 Changes in classes and resources, You can upload them one by one instead of deploying them all at once.
JRebel Is a JAVA Virtual machine plug-ins, It makes the JAVA Programmers can do this without redeploying, See the impact of code changes on an application in real time. Jrebel Fast hot deployment, Save a lot of restart time, Improved personal development efficiency. JRebel It's a set JavaEE development tool.
