I have the following application.properties where I have a Service definition

service.user=${SERVICE_USER}
service.password=${SERVICE_PASSWORD}
service.url=http://someurl.com/api

In the Environment I then specify User and Password

SERVICE_USER=test
SERVICE_PASSWORD=test

The configurations is read in as follows

@Configuration
@ConfigurationProperties(prefix = "service")
public class ServiceConfiguration {

    private String url;

    private String user;

    private String password;

    // setters and getters
}

The issue is that ${SERVICE_PASSWORD} seems not to be resolved. When checking in Debugger it's exactly the value of the variable password. Therefor I can't connect to the Service as it gives the Error "Authentication failed". When I enter the values directly like

service.user=test
service.password=test
service.url=http://someurl.com/api

everything works as expected. Must Environment Variables, that are needed in the Code, be read in directly?

CodePudding user response：

You can refer below configuration to read values from properties file.

@Configuration
public class ServiceConfiguration {

    @Value("${service.url}")
    private String url;

    @Value("${service.user}")    
    private String user;

    @Value("${service.password}")    
    private String password;
}

CodePudding user response：

You can use prefix and do the same like this:

@Configuration

@ConfigurationProperties(prefix = "service")

public class ServiceConfiguration {
@Value("${url}")  
private String url;
@Value("${user}")  
private String user;
@Value("${password}")  
private String password;}
