spring boot 使用 EnvironmentAware 加载配置文件

@Configuration
public class PropertiesUtils implements EnvironmentAware {

	private int redisExpireTime;

	private boolean enabled;

	private int refreshTime;

	@Override
	public void setEnvironment(Environment environment) {
　　　　　　　　　　//解析配置文件头
		 RelaxedPropertyResolver relaxedPropertyResolver = new RelaxedPropertyResolver(environment, "custom.");
		this.redisExpireTime=Integer.valueOf(relaxedPropertyResolver.getProperty("redisExpireTime"));
		this.enabled=Boolean.valueOf(relaxedPropertyResolver.getProperty("enabled"));
		this.refreshTime=Integer.valueOf(relaxedPropertyResolver.getProperty("refreshTime"));
	}
