I have two applications that I need to run simultaneously, and both are trying to run on port
8080. I’d like to change one of them to port
9000. The application I’m trying to change has spring security, so it runs on port
8443 when using
https and port
8080 when using
http. I have to move it from port
8080 without changing any
.java files. Also, I need to run the other application on port
8080 as well, so changing the default tomcat port wouldn’t be a good idea.
I tried adding to
application.properties the lines
spring.main.server.port=9000, then running
mvn install, and then
java -jar target/app.jar.
I also tried running
java -jar target/app.jar with different flags:
Regardless, I get
- Tomcat started on port(s): 8443 (https) 8080 (http).
So, my questions are:
- How do I get it to run on a port different from
- And, what could be causing the configuration files to not change the port?
Run the following command:
mvn spring-boot:run -Drun.jvmArguments='-Dserver.port=8088'
