Spring Boot - Configuration Value from yml is null

Question

im loading a configuration yml using spring configuration annotations. Everything is working fine with 3 of the 4 values I configured. However the 4th Value is null.

Since the other Values are loading properly i dont think there is a configuration Error. Im clueless...

Here is my Code:

Yml-File

spring:
    profiles: test

airtable:
    api-key: xxx
    base: xxx
    proxy: "localhost:8095"
    url: testUrl

mail:
    subjectPrefix: R750Explorer develop - 

PropertiesClass

@Configuration
@ConfigurationProperties(prefix = "airtable")
public class AirtableProperties {

@NotNull
private String apiKey;

@NotNull
private String base;

private String proxy;

private String url;


public String getApiKey() {
    return apiKey;
}

public void setApiKey(String apiKey) {
    this.apiKey = apiKey;
}

public String getBase() {
    return base;
}

public void setBase(String base) {
    this.base = base;
}

public String getProxy() {
    return proxy;
}

public void setProxy(String proxy) {
    this.proxy = proxy;
}

public String getUrl() {
    return url;
}

public void setUrl(String url) {
    this.url = url;
}


}

Autowired them here

public class AirtableRepository {

private final org.slf4j.Logger log = 
LoggerFactory.getLogger(this.getClass());

private Base base = null;

@Autowired
private AirtableProperties prop;

Main Application File

@SpringBootApplication
@EnableCaching
@EnableScheduling
@EnableConfigurationProperties
public class Application extends SpringBootServletInitializer {


public static void main(String[] args) throws Exception {
.
.
.

public static void main(String[] args) throws Exception {

    SpringApplication.run(Application.class, args);
}
}

So I get the Values I define in api-key,base and proxy. However url is null.

========================= Edit =============================

Update. I use both a default application.yml and a profile specific application-test.yml

The above yml is the application-test yml. Heres the application.yml

spring:
    application:
        name: R750Explorer

    boot:
        admin:
            #url: http://localhost:8085       

    devtools:
        restart:
            additional-paths: src, target
            exclude: "**/*.log"

    mail:
        properties:
            mail:
                smp:
                   connectiontimeout: 5000
                   timeout: 3000
                   writetimeout: 5000

    mvc:
        view:
            prefix: /WEB-INF/jsp/
            suffix: .jsp

    output:
        ansi:
            enabled: ALWAYS

    profiles:
        #default: default
        #active: dev 

    airtable:
        api-key: none-default 

    mail:
        from-address: XXX
        to-address: XXX
        user: XXX
        password: XXX

server:
    address: 127.0.0.1
    #port: 9000
    compression:
        enabled: true
    session:
        cookie:
            #comment: # Comment for the session cookie.
            # domain: # Domain for the session cookie.
            http-only: true
            # -> ein Jahr / Maximum age of the session cookie in seconds.
            max-age: 31536000
            #name:  Session cookie name.
            #path: # Path of the session cookie.
            # "Secure" flag for the session cookie.
            secure: true    

logging:
    file: logs/r750explorer.log
    level:
        com:
            sybit: DEBUG

management:
    context-path: /manage
    security: 
        enabled: false
        # roles: SUPERUSER

security:
    user:
        #name: admin
        #password=****

Now heres the clue: If i add url: testurl in the default application.yml under airtable it writes the value. however it doesent in the application-test.yml. Although this is only the case for url not for proxy etc, they are working fine.

Solution

So guys i found the answer. As I already told in the question im using a default application.yml and a application-test.yml.

These 2 were in seperate resource folders ( A copy of the test.yml with a syntax-Error was in the src/resource folder ).

After removing the Copy and implementing this structure everything worked:

| src/resources/

|--> application.yml

| test/resources/

|--> application-test.yml

Because of the Syntax-Error and the false placement of the Files it didnt worked out. Thanks for all the Helpers!

can you try url: 'testUrl'

[Zelle]

Tryed with url: 'testUrl'. No changes.

[pleft]

Have you defined getter and setter methods for url field in your AirtableProperties class?

[Zelle]

Yes, added them so its clear in the question.

[pleft]

Can you run your app in debug mode and place a breakpoint in the setUrl method and examine the values there?

[Barath]

I guess try setting to url from endpointURL in the setter

[Zelle]

I ran the app in debug mode. However it didnt hit the Breakpoint of setUrl. So I tried it with the setProxy Method. There it did stop. So the setUrl Method isnt called to set the Value am I right? What could be the cause?

[Zelle]

Changed the name of endpointUrl to url so it does match no changes.

[PaulNUK]

Check application.yaml doesn't have weird tabs in it for the URL property. Try running it with -Dairtable.url=someurl and see if that works Also inject in an Environment and then debug that to look at the property sources and see if airtable.url is there, or an alternative url property

[Zelle]

checked the yaml for weird tabs etc, no luck. Runnig it with -Dairtable.url=someurl didnt helped either.

[PaulNUK]

Why have you got quotes around this : proxy: "localhost:8095" ?

[Zelle]

it was suggested to try it with quotes because there is a : in there. I tested with single quotes double quotes etc but it doesent matter.

[PaulNUK]

In your example you're setting proxy to localhost:8095 whereas in the original post it's being set to "localhost:8095"' so that is different,

[Barath]

@PaulNUK he edited the question after reading the comments posted by someone. see the time of answered vs question edited

[PaulNUK]

Ah OK, I suspect the quotes are messing it up, based on the fact that your version is working fine.
