How to configure remote debugging jar packages using idea

This article mainly introduces how to configure the use of idea remote debugging jar package, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

1. Start the project remotely

Configure JVM parameters to run

-Xdebug-Xrunjdwp:transport=dt_socket,suspend=n,server=y,address=$ {debug_port}

Start an example:

Java-Xdebug-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=80-jar demo.jar

Nohup java-Xdebug-Xrunjdwp:transport=dt_socket,suspend=n,server=y,address=8189-Dfile.encoding=utf-8-jar demo.jar > demo.log 2 > & 1 &

-Dfile.encoding=utf-8, but not.

Parameter meaning:

-XDebug enables debugging

-Xnoagent disables the default sun.tools.debug debugger

-Djava.compiler=NONE forbids loading of JIT compiler

-Xrunjdwp loads the JPDA reference execution example of JDWP

Transport is used to communicate between debuggers and processes used by JVM

Dt_socket socket transmission

Whether server=y/n JVM needs to be executed as a debugging server

The port number on which the address=2345 debug server is listening

Whether suspend=y/n starts JVM after the debug client establishes a connection

Note: the-jar parameter cannot be written before the-XDebug parameter

2.idea configuration

Choose to add a Remote, configure debug ip or domain name and port port.

Use module classpath: select a debug module

3.debug start

You can break the mode.

4. Connected successfully

Note: need to ensure consistency between local and remote code

The following error indicates that the jar was not executed or the jar package was not executed successfully, resulting in a failure to connect
