Where is the application properties file in a Spring Boot project

Question

I started a new Spring boot project  I want to change the port number and I read that I have to modify the  resource application properties to do so    I cannot locate this file however  did I miss something  Do I need to install a boot starter  I don t want to set this using the spring CLI    Should I create this file manually  If so  I think I ll have to mark this file as the properties file somewhere in the code  Where would that be   Thanks a lot

You will need to add the application properties file in your classpath     If you are using Maven or Gradle  you can just put the file under src main resources  If you are not using Maven or any other build tools  put that under your src folder and you should be fine   Then you can just add an entry server port   xxxx in the properties file

You can also create the application properties file manually    SpringApplication will load properties from application properties files in the following locations and add them to the Spring Environment    A  config subdirectory of the current directory  The current directory A classpath  config package The classpath root   The list is ordered by precedence  properties defined in locations higher in the list override those defined in lower locations    From the Spring boot features external configuration doc page   So just go ahead and create it
