actuator 提供的端点信息

监控检查url： http://localhost:8888/ + 端点

端点	描述	HTTP 方法
auditevents	显示通用的监控信息	GET
beans	显示应用程序上下文所有的Spring bean	GET
configprops	显示所有 @ConfigurationProperties 的配置属性列表	GET
dump	显示线程活动的快照	GET
env	显示应用的环境变量	GET
health	显示应用程序的健康指标，这些值由HealthIndicator的实现类提供。常见取值：UP / DOWN / UNKNOWN / OUT_OF_SERVICE	GET
info	显示应用的信息，可使用 info.* 属性自定义info端点公开的数据	GET
mappings	显示所有的URL路径	GET
metrics	显示应用的度量标准信息	GET
shutdown	关闭应用（默认情况下不启用，如需启用，需设置endpoints.shutdown.enabled=true）	POST
sessions	程序sessions的信息	GET
conditions	显示配置的条件和原因	GET
httptrace	显示http追踪信息	GET
loggers	显示修饰和配置的日志	GET
scheduledtasks	显示程序中预定的任务	GET

##druid实时信息监控

Druid是Java语言中最好的数据库连接池。

Druid能够提供强大的监控和扩展功能。

###资源引入

	<dependency>
		<groupId>com.alibaba</groupId>
		<artifactId>druid</artifactId>
		<version>${druid-version}</version>
	</dependency>

##自定义监控端点

工程化项目需要对自身项目进行监控，本demo是对功能信息考察
