Using Dynamic Resource Properties
If you want to use dynamic properties in your spring applications then it is best to make a class and use @ConfigurationProperties.
application.properties
logging.level.org.springframework=debug
#spring.profiles.active=dev
currency-service.url=http://brains.com
currency-service.username=defaultUsername
currency-service.key=defaultKey
package com.brains.springboot.learnspringboot;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import lombok.Data;
@ConfigurationProperties(prefix = "currency-service")
@Data
@Component
public class CurrencyServiceConfiguration {
private String url;
private String username;
private String key;
}
package com.brains.springboot.learnspringboot;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class CourseController {
@Autowired
private CurrencyServiceConfiguration currencyServiceConfiguration;
@GetMapping("/currency")
public CurrencyServiceConfiguration getCurrencyDetails() {
return currencyServiceConfiguration;
}
}
