Spring boot properties file tips

I jot down random tech stuff here. It's great if it helps others too but the main intent is for me to come back later and refer to it, if ever. So don't expect the posts to be detailed or organized.

Setting a variable with the value of a property from .properties file (note how spring does automatic type conversion to int)

    @Value("${some.property}")
    private int SOME_PROPERTY;
Enter fullscreen mode Exit fullscreen mode

Use a default property value if the specified property is not present

    @Value("#{'${prop.val.specific:${prop.val.default:}}'}")
    private String PROP_VALUE;
Enter fullscreen mode Exit fullscreen mode

Setting comma separated values to a List

    @Value("#{'${comma.separated.property}'.split(',')}")
    private List<String> COMMA_SEPARATED_PROPERTY;
Enter fullscreen mode Exit fullscreen mode
