This article mainly introduces "IDEA how to remotely debug the server's java project". In the daily operation, I believe many people have doubts about how to remotely debug the server's java project in IDEA. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubt of "how to remotely debug the server's java project". Next, please follow the editor to study!

The server program runs on a remote server, and we can set a breakpoint in the local server code (provided that the local code must be consistent with the code run by the remote server). Whenever a request is made to the remote server, the internal state of the remote server at this time can be known locally.

Run the server code using the JVM parameter of remote debugging

-Xdebug-Xrunjdwp:transport=dt_socket,suspend=n,server=y,address=5005

Among them, 5005 is the port for remote debugging.

Local Idea connects to remote server debug port

Open Intellij IDEA and select "Edit Configurations …" on the top right. After going in, click the + sign and select "Remote". According to the following figure, just fill in the contents in the red box, where host is the ip/hostname,port of the machine on which the remote code is running, and the remote debugging port specified in the previous step is 5005 in this example.

Start debug mode

Now select "Edit Configurations …" in the previous step. Select the name of the remote created in the previous step, and then click the debug button on the right (which looks like the bug one) to view the console log. If words like "Connected to the target VM, address: 'xx.xx.xx.xx:5005', transport:' socket'" appear, the connection has been successful.

Set breakpoints and start debugging

Set the breakpoint, access the remote server to trigger the breakpoint, idea will automatically jump to the breakpoint, and the variable value also displays the variable value of the remote server.

At this point, the study on "how to remotely debug the java project on the server side of IDEA" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
