   Modify the configuration in the Semios-Gateway/src/resources/application-test.yml file
   Default:
   API:  http://localhost:9480 
   DEX:  http://localhost:9483
   

2. Build and run the service:

   Path_To_GC_Log_File:The path to GC log files, such as:/home/ubuntu/semios/gateway/logs/gc.log

   Path_To_Log:The path to store the log file, such as:/home/ubuntu/semios/gateway/logs/gateway.log

   Service_IP: Service IP address, such as: 127.0.0.1

   cd Semios-Gateway
   mvn clean install && mvn package
   java -jar -Xms128m -Xmx128m -XX:MetaspaceSize=64M -XX:MaxMetaspaceSize=128M -XX:+UseG1GC -Xloggc:{Path_To_GC_Log_File} -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -Dspring.profiles.active=test -Dserver.port=9482 -Dlogging.file.path={Path_To_Log} -Dserver.address={Service_IP} target/protodao-gateway-0.0.1-SNAPSHOT.jar
