Autowired Environment is null

Autowired Environment is null

自动装配发生的时间比

load()

所谓的晚（由于某种原因）。

一种解决方法是实现

EnvironmentAware

并依赖Spring调用

setEnvironment()

方法：

@Configuration@ComponentScan(basePackages = "my.pack.offer.*")@PropertySource("classpath:OfferService.properties")public class PropertiesUtil implements EnvironmentAware {    private Environment environment;    @Override    public void setEnvironment(final Environment environment) {        this.environment = environment;    }    @Bean    public String load(String propertyName)    {        return environment.getRequiredProperty(propertyName);    }}
