Make IntelliJ aware of a properties file

问题

Is there some way to tell IntelliJ that a particular .properties file will be loaded into a project's environment? We use @PropertySource annotations to load properties files, and in several places load override values from a file determined by an already-configured property, like so:

@Configuration
@PropertySource("classpath:com/example/package/db.properties")
@PropertySource("classpath:com/example/package/db.${db.instance}.properties")
public class DatabaseConfig {
    private @Value("${db.someProperty}") String someDBProperty;
    // ...
}

The problem is that within one of these indirectly referenced files, e.g. db.test.properties, IntelliJ doesn't know if/how the properties file is referenced, so it can't tie any of the entries to their usages. (Bizarrely, some of the properties listed in these files are not greyed out to indicate 'Unused property', though even these give no results for a 'Find usages' search). There is no issue with directly named files, e.g. db.properties above.

Is there some way to tell IntelliJ about these files short of creating additional dummy @Configuration files that reference them?

This is how I do it:

From the project explorer, i right click in src/main/resources, I hover on "Mark Directory As..." and I click on "Resources Root"

In the Spring configuration I just specify the name of the properties file directly.

Here an example when I am doing this in one of my projects: https://github.com/SFRJ/springpractice/blob/master/src/main/java/part3/PropertiesLoaderConfiguration.java

By the way, if you are using multiple property sources you can also do something like this:

@PropertySources({
        @PropertySource("a.properties"),
        @PropertySource("b.properties")
    })

This can be set in project structure. Just look at this capture.

回答3:

Create a folder named res in your project and keep the necessary property files in that folder. Go to the Project_Structures -> Modules and select the tab Resources. In your code, you can access the resource file using the path: res/your_file_name.
