How to read data from java properties file using Spring Boot

by

You can use @PropertySource to externalize your configuration to a properties file. There is number of way to do get properties:

1.
Assign the property values to fields by using @Value with PropertySourcesPlaceholderConfigurer to resolve ${} in @Value:

@Configuration
@PropertySource("file:config.properties")
public class ApplicationConfiguration {

    @Value("${gMapReportUrl}")
    private String gMapReportUrl;

    @Bean
    public static PropertySourcesPlaceholderConfigurer propertyConfigInDev() {
        return new PropertySourcesPlaceholderConfigurer();
    }

}

2.
Get the property values by using Environment:

@Configuration
@PropertySource("file:config.properties")
public class ApplicationConfiguration {

    @Autowired
    private Environment env;

    public void foo() {
        env.getProperty("gMapReportUrl");
    }

}

Hope this can help
