Run/Debug Configuration: Spring BootUltimate

If necessary, specify the command-line options to be passed to the server JVM at the server start.

• Use spaces to separate options, for example, -client -ea -Xmx1024m.

• If an option includes spaces, enclose the spaces or the argument itself in double quotes, for example, some" "arg or "some arg".

• If an option includes double quotes as part of the argument, escape the double quotes using backslashes, for example, -Dmy.prop=\"quoted_value\".

• You can pass environment variable values to custom Java properties. For example, if you define a variable MY_ENV_VAR, you can pass it to the foo property:

  -Dfoo=${MY_ENV_VAR}

Select a method that will be used to shorten the command line if the classpath gets too long or you have many VM arguments that exceed your OS command line length limitation:

• none: IntelliJ IDEA will not shorten a long classpath. If the command line exceeds the OS limitation, IntelliJ IDEA will be unable to run your application and will display a message suggesting you to specify the shortening method.

• JAR manifest: IntelliJ IDEA will pass a long classpath via a temporary classpath.jar. The original classpath is defined in the manifest file as a class-path attribute in classpath.jar. Note that you will be able to preview the full command line if it was shortened using this method, not just the classpath of the temporary classpath.jar.

• classpath.file: IntelliJ IDEA will write a long classpath into a text file.

tip

Using the Enable JMX agent option might slow down the application startup.

Enables JMX agent that shows application endpoints data by adding the following VM options (requires Spring Boot 1.3.0 or later):

• -Dcom.sun.management.jmxremote
• -Dspring.jmx.enabled=true
• -DSpring.liveBeansView.mbeanDomain
• -Dspring.application.admin.enabled=true

note

The Spring Boot endpoints feature is not available by default for Windows users with the FAT file system. To enable it, add -XX:+PerfBypassFileSystemCheck to VM options, and make sure that %TMP%\hsperfdata_username has permissions for full folder access.

IntelliJ IDEA uses local JMX connector for retrieving Spring Boot actuator endpoint's data. However, it is impossible to get local JMX connector address if Spring Boot application and IntelliJ IDEA JVMs have different bitness and you are using OpenJ9 JDK. In this case, add the following lines to VM options:

• -Dcom.sun.management.jmxremote.port={some_port}
• -Dcom.sun.management.jmxremote.authenticate=false
• -Dcom.sun.management.jmxremote.ssl=false

note

As mentioned in the official Oracle documentation, this configuration is insecure. Any remote user who knows (or guesses) your port number and host name will be able to monitor and control your Java applications and platform.

Specify an action that the IDE will do after you click Update <application name> Application:

• Update resources — compile all modified and dependent resource files.

• Update classes and resources — compile all modified and dependent files.

• Update trigger file — update the trigger file. Set up the trigger filename by adding the -Dspring VM option.

• Hot swap classes and update trigger file if failed — (available only in the debug mode) compile all modified and dependent files, hot swap classes, update the trigger file if the hot swap failed. Specify the trigger filename by adding the
  -Dspring.devtools.restart.trigger-file=.restartTriggerFile VM option.

Specify an action that the IDE will do after you switch to another application (other than IntelliJ IDEA):

• Update resources — compile all modified and dependent resource files.

• Update classes and resources — compile all modified and dependent files.
