说明:
@Configuration项目启动时加载
@component (把普通pojo实例化到spring容器中,相当于配置文件中的 <bean id="" class=""/>)泛指各种组件,就是说当我们的类不属于各种归类的时候(不属于@Controller、@Services等的时候),我们就可以使用@Component来标注这个类。
properties 为读取的peoperties文件集合
使用:
@Autowired
private PropertiesConfig propertiesConfig;
propertiesConfig.getProperty(key);
***暂时未找到获取所有properties文件路径
