Setting additional profiles before the run command results in error

[ADarkDividedGem]

Firstly thanks for the great work you have done.

Recently I decided to set the active profile in my Spring Boot application programmatically so I didn't have to change the setting manually each time I changed the deployment.

This meant changing how the application was run which originally used the basic line:
SpringApplication.run(BasicApplication.class, args);

To the following:

import it.ozimov.springboot.mail.configuration.EnableEmailTools;
import org.apache.commons.lang3.SystemUtils;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@EnableEmailTools
public class BasicApplication {
    public static void main(String[] args) {
        SpringApplication application = new SpringApplication(BasicApplication.class);        
        String profile = "production";
        if(SystemUtils.IS_OS_WINDOWS){
            profile = "development";
        }
        application.setAdditionalProfiles(profile);        
        application.run(args);        
    }
}

The above code then returns the following error message:

---

APPLICATION FAILED TO START

Description:

Field mailSender in uk.co.freescanner.web.controller.ContactController required a bean of type 'org.springframework.mail.javamail.JavaMailSenderImpl' that could not be found.

• Bean method 'mailSender' not loaded because AnyNestedCondition 0 matched 2 did not; NestedCondition on MailSenderAutoConfiguration.MailSenderCondition.JndiNameProperty @ConditionalOnProperty (spring.mail.jndi-name) did not find property 'jndi-name'; NestedCondition on MailSenderAutoConfiguration.MailSenderCondition.HostProperty @ConditionalOnProperty (spring.mail.host) did not find property 'host'

Action:

Consider revisiting the conditions above or defining a bean of type 'org.springframework.mail.javamail.JavaMailSenderImpl' in your configuration.

Is it possible that by using application.run(args); instead of SpringApplication.run(BasicApplication.class, args); that it has thrown off the auto configuration some how?

Hi @ADarkDividedGem,
I much appreciated your gratitude. I would like to deserve more time to this project (e.g. I would like to migrate to Spring Boot 2.x), but I'm completely alone and due to other projects I can't afford everything alone at the moment.

Let's focus on the issue you are facing. I assume you use Spring Boot 1.5.x.

I have a few questions:

1. Which OS are you running?
2. If you run the app using the following code works?

import it.ozimov.springboot.mail.configuration.EnableEmailTools;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@EnableEmailTools
public class BasicApplication {
  public static void main (Stirng ... args) {
    SpringApplication.run(BasicApplication.class, args);
  }
}

3. If you execute the following main works?

import it.ozimov.springboot.mail.configuration.EnableEmailTools;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@EnableEmailTools
public class BasicApplication {
  public static void main (Stirng ... args) {
        SpringApplication application = new SpringApplication(BasicApplication.class);        
        application.run(args);     
  }
}

Finally, can you try something like

@Configuration
public class OSBasedApplicationInitializer implements WebApplicationInitializer {     
  @Override    
  public void onStartup(ServletContext servletContext) throws ServletException {
        String profile = "production";
        if(SystemUtils.IS_OS_WINDOWS){
            profile = "development";
        }
        servletContext.setInitParameter("spring.profiles.active", profile);    
  }
}

Thanks for the quick reply, after coming back to the problem with fresh eyes and thanks to your examples, a new perspective, I got it working.

Turns out there was nothing wrong with your code, instead it was just my misunderstanding of how profiles worked. After reading the documentation on Profile-specific Properties I assumed you needed to rename application.properties to application-default.properties for it to be recognised as the default properties file when adding additional profiles.

Once I renamed it back to application.properties the defaults properties for spring.mail. were loaded back in and the application ran fine.

Sorry for taking up your time, like you I am also working solo on my project so I appreciate all the help I can get.

You can actually have one property file per profile or a single one that is multiprofile (and I think also a common properties and then those for the different profiles).

Glad everything works.
Best
