spring啓動時初始化properties文件

spring配置文件 

<bean id="dataCenter" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
        <property name="location" value="classpath:datacenter.properties"/>
    </bean>

@Data
@Component
public class DataCenter implements InitializingBean {

    //注入bean
    @Resource
    private Map<String,String> dataCenter;

    private String baseUrl;
    private Map<String,String> remoteCalls = new HashMap();

    static final String BASE_URL_PROPERTY_NAME = "bbd.datacenter.baseurl";
    static final String INTERFALCES_PREFIX="bbd.datacenter.remoteCall.";



    @Override
    public void afterPropertiesSet() throws Exception {
        dataCenter.entrySet().forEach(entry->{
            if(BASE_URL_PROPERTY_NAME.equals(entry.getKey())){
                baseUrl = entry.getValue();
            }else if(entry.getKey().startsWith(INTERFALCES_PREFIX)){
                remoteCalls.put(entry.getKey().replace(INTERFALCES_PREFIX,""),entry.getValue());
            }
        });
    }
}
