I am trying to use properties from a .properties file, but it doesn\'t seem to work.

Here is my code:

@Service(\"ServiceFTP\")
@Transact         


        

Answer 1

This Issue occurs if the application is unable to access the some_file_name.properties file.Make sure that the properties file is placed under resources folder in spring.

Trouble shooting Steps

1: Add the properties file under the resource folder.

2: If you don't have a resource folder. Create one by navigating new by Right click on the project new > Source Folder, name it as resource and place your properties file under it.

For annotation based Implementation

Add @PropertySource(ignoreResourceNotFound = true, value = "classpath:some_file_name.properties")//Add it before using the place holder

Example:

Assignment1Controller.Java

@PropertySource(ignoreResourceNotFound = true, value = "classpath:assignment1.properties")
@RestController  
public class Assignment1Controller {

//  @Autowired
//  Assignment1Services assignment1Services;
    @Value("${app.title}")
    private String appTitle;
     @RequestMapping(value = "/hello")  
        public String getValues() {

          return appTitle;

        }  

}

assignment1.properties

app.title=Learning Spring
