Spring boot get #value within a class extending a dependency - spring-boot

Question

Folks, am trying to access config properties from within a class that I've extended from a dependency. Apparently the config class is returning a null pointer in my implementation class (CustomUtil).
pom.xml
...
<dependency>
<groupId>com.utilapp</groupId> //3rd party library that I need to use
<artifactId>util-lib</artifactId>
</dependency>
...
The BaseUtil is from the dependency. CustomUtil is a bean in my SpringBoot App & am overriding the method as below to check the key from the config property ignoreKeyList .
package com.myapp
...
#Component
public class CustomUtil extends BaseUtil {
#Autowired
private ClientConfig clientConfig; // This returns null!
#Override
protected boolean shouldExcludeFromList(String key) {
return this.clientConfig.getIgnoreKeyList.contains(key); // their library/util excludes certain keywords from the content being formatted
}
}
Config class in my SpringBoot App.
package com.myapp
...
#Configuration
#Getter
#Setter
public class ClientConfig {
#Value("${myapp.ignorekeys}")
private List<String> ignoreKeyList;
...
...
}
Main class in my app.
package com.myapp
...
#SpringBootApplication
public class MyClientApplication {
public static void main(String[] args) {
SpringApplication.run(MyClientApplication.class, args);
}
}
Service implementation class in my SpringBoot App.
package com.myapp
import com.utilapp.formatters.FormatBuilder;
import com.utilapp.formatters.TextFormatter;
...
#Service
public class ServiceImpl implements MyService {
#Autowired
private ClientConfig clientConfig; // works here!
public String formatContent(String content) {
TextFormatter formatter = this.getTextFormatter();
return formatter.parseAndFormat(content);
}
private TextFormatter getTextFormatter() {
return FormatBuilder.custom() // FormatBuilder is from the dependency
.withApplication(this.clientConfig.getAppName()) // In their library, the BaseUtil gets instantiated which am extending in my CustomUtil bean
...
...
.withIndentSupport(Boolean.TRUE)
.build();
}
}
Controller in my app
package com.myapp
...
#RestController
#RequestMapping("/app/v1")
public class StyleController {
#Autowired
private MyService myService;
#GetMapping("/format")
public String formatContent(#RequestParam String content) {
return this.myService.formatContent(content);
}
}
When I debug ClientConfig, it loads the properties from the config file; application.properties in src\main\resources.
But for some reason the ClientConfig is returning null from within the CustomUtil bean. Not sure why!
I originally thought it was due to ordering of bean instantiation. I tried playing around with #Order, #DependsOn, #ComponentScan, #ScanBasePackages etc, but none yields.
Any pointers/guidance please.
Thanks.
