两种方式可以实现初始化配置信息
①： 实现CommandLineRunner，重写run()
②： 实现ApplicationRunner，重写run()

@Component
@Order(3)//根据order的值的大小决定启动顺序
public class InitializeSetting implements ApplicationRunner {
	
	@Value("${PROJECT_NAME}")
	private String PROJECT_NAME;
	
	@Value("${PACKAGE_NAME}")
	private String PACKAGE_NAME;
	
	@Value("${SETTING_NAME}")
	private String SETTING_NAME;
	
    //将获取的配置信息放到静态变量中
	@Override
	public void run(ApplicationArguments args) throws Exception {
		StaticVariable.projectName = PROJECT_NAME;
		StaticVariable.packageName = PACKAGE_NAME;
		StaticVariable.settingName = SETTING_NAME;
	}
	
}

存储配置信息类

/***
 * 
 * @author shy
 * @deprecated 项目配置赋值
 */
public class StaticVariable {
	
	public static String projectName;
	public static String packageName;
	public static String settingName;
}

可以用StaticVariable.projectName，StaticVariable.packageName，StaticVariable.settingName 在项目中使用
