{"title":"What is the default port number for a Spring Boot application?","content":"The default port number for a Spring Boot application is 8080. When you create and run a Spring Boot application, if you do not explicitly specify another port in the configuration file (such as application.properties or application.yml), the application will default to listening on port 8080.
For example, the following is an example of the content of an application.properties file for a simple Spring Boot application:
# If server.port is not set, Spring Boot will default to using 8080 server.port=8080
If you do not set server.port or leave it empty, Spring Boot will default to using port 8080. This ensures conflict-free operation in most development environments, as port 8080 is commonly regarded as the standard port for HTTP services in development. If port 8080 is already occupied by another service, developers can easily specify a different port by changing the value of server.port."}
