Autowired Environment is null
我在将环境连接到Spring项目时遇到问题。在这个班上
@Configuration@ComponentScan(basePackages = "my.pack.offer.*")
@PropertySource("classpath:OfferService.properties")
public class PropertiesUtil {
    @Autowired
    private Environment environment;
    @Bean
    public String load(String propertyName)
    {
        return environment.getRequiredProperty(propertyName);
    }
}
环境始终为null。
回答:
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);
    }
}
以上是 Autowired Environment is null 的全部内容, 来源链接: utcz.com/qa/417514.html
