Autowired Environment is null

Question

I have an issue with connecting environment to my Spring project. In this class

@Configuration
@ComponentScan(basePackages = \"my.pack.offer.*\")
@PropertyS         


        

Answer 1

Change @Autowired for @Resource (from javax.annotation) and make it public e.g.:

@Configuration
@PropertySource("classpath:database.properties")
public class HibernateConfigurer {

    @Resource
    public Environment env;

    @Bean
    public DataSource dataSource() {
        BasicDataSource dataSource = new BasicDataSource();
        dataSource.setDriverClassName(env.getProperty("database.driverClassName"));
        dataSource.setUrl(env.getProperty("database.url"));
        dataSource.setUsername(env.getProperty("database.username"));
        dataSource.setPassword(env.getProperty("database.password"));
        dataSource.setValidationQuery(env.getProperty("database.validationQuery"));

        return dataSource;
    }
}

And you must register your configurer class in WebApplicationInitializer this way

AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
context.register(ApplicationConfigurer.class); //ApplicationConfigurer imports HibernateConfigurer

It's working for me! You may want to check a test project I made.
