在服务中读取application.yml

Question

I have a oracle rest end point, and I read the entries from there. This is my application.yml

spring:
  profiles:
    active: dev
oracleUrl: https://cloud-url/filter_by/login_id/

OracleProperties

@Configuration
@ConfigurationProperties
public class OracleProperties {

    @Value("${oracleUrl}")
    String oracleUrl;

    public String getOracleUrl() {
        return oracleUrl;
    }

    public void setOracleUrl(String oracleUrl) {
        this.oracleUrl = oracleUrl;
    }
}

Application.java

@EnableConfigurationProperties({OracleProperties.class})
@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Service

@Autowired
private OracleProperties oracleProperties;

String oracleUrl = oracleProperties.getOracleUrl();

My oracleUrl is null, Please let me know where I am going wrong.

You don't need @Configuration annotation on OracleProperties . The @ConfigurationProperties("oracle") will pick up any properties with prefix oracle . Helps to group a family of properties with oracle prefix. Also Notice, there is no @Value on top of url attribute.

@ConfigurationProperties("oracle")
public class OracleProperties {

    private String url;

    public String getUrl() {
        return oracleUrl;
    }

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

Changes to your application.yml ,

oracle:
  url: https://cloud-url/filter_by/login_id/
