JAVA itself supports the debugging function, and provides a simple debugging tool - JDB, similar to the powerful GDB, JDB is also a character interface debugging environment, and supports setting breakpoints, and supports thread-level debugging.
1. Add to the process startup parameters on the server:
-Xdebug -Xrunjdwp:transport=dt_socket,address=5555,server=y,suspend=n

-Xrunjdwp is to inform the JVM to use (java debug wire protocol) to run the debugging environment. This parameter has a series of debugging options at the same time:
transport specifies the transmission method of debugging data
dt_socket refers to using SOCKET mode
server=y/n Whether the VM needs to be executed as a debug server
suspend=y/n Whether to start the VM after the debug client establishes a connection
Connect to the debugging service provided by myhost:5555, select Remote JVM Debug in Edit Configurations in idea and add the following:
