Idea's debug debugging server springboot project

The online code needs to be the same as the local one, remember to open the server port (firewall)

1. Write a shell script to start the jar project

#!/bin/sh
# 定义变量
JAR_NAME="$2.jar"
# 监听端口
ADD_PORT="$3"
# 该方法会重新启动程序
debug() {
    
    
  # 查看pid,先杀掉，再运行jar
  pid=$(ps -ef | grep $JAR_NAME | grep -v grep | awk '{print $2}')
  # 设置默认监听端口
  if [ -z $ADD_PORT ]; then
    ADD_PORT="51135"
    echo "......default Listen on port for DEBUG:${ADD_PORT}"
  fi
  # -z 表示为空
  if [ ! -z $pid ]; then
    kill -9 $pid
    echo ""
    echo "......kill -9 ${pid}....."
    nohup java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=$ADD_PORT -Dloader.path=lib/ -jar $JAR_NAME >debugOut.log 2>&1 &
    pid=$(ps -ef | grep $JAR_NAME | grep -v grep | awk '{print $2}')
    echo ""
    echo "debug Service ${JAR_NAME} is starting！newPid:${pid}, Listen on port:${ADD_PORT}"
    echo "......debug restart: success......"
    echo ""
  else 
    nohup java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=$ADD_PORT -Dloader.path=lib/ -jar $JAR_NAME >debugOut.log 2>&1 &
    pid=$(ps -ef | grep $JAR_NAME | grep -v grep | awk '{print $2}')
    echo ""
    echo "debug Service ${JAR_NAME} is starting！pid:${pid}, address:${ADD_PORT}"
    echo "......debug Start： success......"
    echo ""
  fi
}
# 根据输入参数执行对应方法
case "$1" in
"debug")
  debug
  ;;
esac

Two, idea configuration connection

Debugger mode : Choose Attach to remote JVM
Host: The IP of your own server;
Port: Listening port, not the same as the port of the program
Command line arguments for remote JVM: Choose according to the jdk version installed by yourself
Use module classPath: Generally, idea will be automatically selected as your project name

Three, test

1. Use tools: network debugging assistant, test interface with postman is also wide

Network debugging assistant download address Password: mkd7 Netty service嘞

2. Linux run jar project

[root@kong demo]# ls
demo_logs  lib  demo-1.2.jar  start.sh
[root@kong demo]# sh start.sh debug demo-1.2
......default Listen on port for DEBUG:51135

debug Service demo-1.2.jar is starting！pid:23084, address:51135
......debug Start： success......
[root@kong demo]#

[root@kong dust]# sh start.sh debug demo-1.2 12364

......kill -9 23084......

debug Service demo-1.2.28.jar is starting！newPid:23234, Listen on port:12364
......debug restart: success......

[root@kong dust]#
