SpringBoot2.x carregado application.properties meios outros arquivos de recursos

1, @ PropertySource anotação modo

recurso personalizado arquivos custom.properties

@Configuration
@PropertySource(value = "custom.properties")
public class EnvironmentTest implements CommandLineRunner{

    @Value("${test.param1:}")
    private String param1;

    @Override
    public void run(String... strings) throws Exception {
        System.out.println("read test.param1: "+param1);
    }
}

2, implementar a interface de EnvironmentPostProcessor

public class CustomEnvironmentPostProcessor implements EnvironmentPostProcessor {

    private final Properties properties = new Properties();
    /**
     * The Profiles.
     */
    private String[] profiles = {
            "custom.properties",
    };

    @Override
    public void postProcessEnvironment(ConfigurableEnvironment configurableEnvironment, SpringApplication springApplication) {
        for (String profile : profiles) {
            Resource resource = new ClassPathResource(profile);
            configurableEnvironment.getPropertySources().addLast(loadProfiles(resource));
        }
    }

    private PropertySource<?> loadProfiles(Resource resource) {
        if (!resource.exists()) {
            throw new IllegalArgumentException("file" + resource + "not exist");
        }
        try {
            properties.load(resource.getInputStream());
            return new PropertiesPropertySource(resource.getFilename(), properties);
        } catch (IOException ex) {
            throw new IllegalStateException("load resource exception" + resource, ex);
        }
    }

}

spring.factories adicionar o EnvironmentPostProcessor

3, adicionado directamente ao meio ambiente em

@Configuration
public class CustomPropertiesLoadConfig {

    @Autowired
    private Environment environment;

    @PostConstruct
    public void load(){
        if(environment instanceof StandardEnvironment){
            MutablePropertySources propertySources = ((StandardEnvironment) environment).getPropertySources();
            Resource resource = new ClassPathResource("custom.properties");
            Properties properties = new Properties();
            try {
                properties.load(resource.getInputStream());
            } catch (IOException e) {
                e.printStackTrace();
            }

            propertySources.addFirst(new PropertiesPropertySource("customPorperties", properties));
        }
    }
}

Faça o teste

@Configuration
public class EnvironmentTest implements CommandLineRunner {

    @Value("${test.param1:}")
    private String param1;

    @Override
    public void run(String... strings) throws Exception {

        System.out.println("read test.param1: "+ param1);
    }
}

No entanto, esta abordagem deve prestar atenção para carregar a configuração do feijão de dar prioridade para obter a configuração do feijão é carregado.

4, spring.profile.include

O arquivo de configuração foi renomeada application-custom.properties
spring.profile.include direta a aumentar em application.properites no.

spring.profiles.include=custom
