How to read application.properties in utils class

I am writing a REST service using Spring Boot.

Method in my rest service calls a util class and this util class needs to refer certain properties defined in the application.properties

I user @Value and it didnt work inside the util class, where as it works in my REST service class.

My REST service: ReportsController.java

@RestController
@RequestMapping("/api/v1")
public class ReportsController

@Value("$report.path")
private String reportPath;

@GetMapping
@RequestMapping("/welcome")
public String retrieveWelcomeMessage()
return new ExcelFileUtil().test();

@GetMapping
@RequestMapping("/welcome1")
public String retrieveWelcomeMessage()
return reportPath;




My Utils class: MyUtil.java

public class MyUtil

@Value("$report.path")
private String reportPath;

public String test()

return reportPath;




I am getting the value from application.properties is printed for http://localhost:8080/api/v1/welcome1
But getting blank for http://localhost:8080/api/v1/welcome

How to make the application.properties readable inside the MyUtil.java?

Make your Util class as a component of spring. @Value will work only on spring managed dependencies

@Component
public class MyUtil

@Value("$report.path")
private String reportPath;

public String test()
return reportPath;




Make sure the package of MyUtil is added to component-scan

..and use the MyUtil as a Autowired dependency whereever you want to use like

@RestController
@RequestMapping("/api/v1")
public class ReportsController{

@Autowired
private MyUtil myUtil;

public void someMethod()
myUtil.reportPath();
