JAVA remote debug

Enable the remote Debug mode of JVM and add the following parameter when starting JVM: // non-blocking mode. After jvm is started, attach to the server at any time-Xdebug-Xnoagent-Xrunjdwp: transport = dt_socket, address = 11312, server = y, suspend = n // block debug. After JVM is started, the JVM will continue to execute this operation only when attach is remotely connected to the corresponding port. -Xdebug-Xnoagent-Xrunjdwp: transport = dt_socket, address = 11312, server = y, suspend = y the second program module is particularly suitable for debugging class initialization. In eclipse, the bug items include Debug Configurations... selected. Select remove java application and create a Project, which is the JAVA source code file Project that you want to remotely debug. HOST is the name or IP address of the server. PORT is the preceding address item 11312. Set the Connection Type to Standard. Click debug. If a connection error occurs after debug. 1. Check whether the server or service has been started. 2. Check whether the configuration is correct. 3. Check whether the port is occupied by other programs. If the above detection is complete, the connection still fails. Restart eclipse or restart server to solve the problem. In addition, the Xnoagent option is generally not required in remote debug.
